+# react-dev-utils
+
+This package includes some utilities used by [Create React App](https://github.com/facebook/create-react-app).<br>
+Please refer to its documentation:
+
+- [Getting Started](https://facebook.github.io/create-react-app/docs/getting-started) – How to create a new app.
+- [User Guide](https://facebook.github.io/create-react-app/) – How to develop apps bootstrapped with Create React App.
+
+## Usage in Create React App Projects
+
+These utilities come by default with [Create React App](https://github.com/facebook/create-react-app). **You don’t need to install it separately in Create React App projects.**
+
+## Usage Outside of Create React App
+
+If you don’t use Create React App, or if you [ejected](https://facebook.github.io/create-react-app/docs/available-scripts#npm-run-eject), you may keep using these utilities. Their development will be aligned with Create React App, so major versions of these utilities may come out relatively often. Feel free to fork or copy and paste them into your projects if you’d like to have more control over them, or feel free to use the old versions. Not all of them are React-specific, but we might make some of them more React-specific in the future.
+
+### Entry Points
+
+There is no single entry point. You can only import individual top-level modules.
+
+#### `new InterpolateHtmlPlugin(htmlWebpackPlugin: HtmlWebpackPlugin, replacements: {[key:string]: string})`
+
+This webpack plugin lets us interpolate custom variables into `index.html`.<br>
+It works in tandem with [HtmlWebpackPlugin](https://github.com/ampedandwired/html-webpack-plugin) 2.x via its [events](https://github.com/ampedandwired/html-webpack-plugin#events).
+
+```js
+var path = require('path');
+var HtmlWebpackPlugin = require('html-webpack-plugin');
+var InterpolateHtmlPlugin = require('react-dev-utils/InterpolateHtmlPlugin');
+
+// webpack config
+var publicUrl = '/my-custom-url';
+
+module.exports = {
+  output: {
+    // ...
+    publicPath: publicUrl + '/',
+  },
+  // ...
+  plugins: [
+    // Generates an `index.html` file with the <script> injected.
+    new HtmlWebpackPlugin({
+      inject: true,
+      template: path.resolve('public/index.html'),
+    }),
+    // Makes the public URL available as %PUBLIC_URL% in index.html, e.g.:
+    // <link rel="icon" href="%PUBLIC_URL%/favicon.ico">
+    new InterpolateHtmlPlugin(HtmlWebpackPlugin, {
+      PUBLIC_URL: publicUrl,
+      // You can pass any key-value pairs, this was just an example.
+      // WHATEVER: 42 will replace %WHATEVER% with 42 in index.html.
+    }),
+    // ...
+  ],
+  // ...
+};
+```
+
+#### `new InlineChunkHtmlPlugin(htmlWebpackPlugin: HtmlWebpackPlugin, tests: Regex[])`
+
+This webpack plugin inlines script chunks into `index.html`.<br>
+It works in tandem with [HtmlWebpackPlugin](https://github.com/ampedandwired/html-webpack-plugin) 4.x.
+
+```js
+var path = require('path');
+var HtmlWebpackPlugin = require('html-webpack-plugin');
+var InlineChunkHtmlPlugin = require('react-dev-utils/InlineChunkHtmlPlugin');
+
+// webpack config
+var publicUrl = '/my-custom-url';
+
+module.exports = {
+  output: {
+    // ...
+    publicPath: publicUrl + '/',
+  },
+  // ...
+  plugins: [
+    // Generates an `index.html` file with the <script> injected.
+    new HtmlWebpackPlugin({
+      inject: true,
+      template: path.resolve('public/index.html'),
+    }),
+    // Inlines chunks with `runtime` in the name
+    new InlineChunkHtmlPlugin(HtmlWebpackPlugin, [/runtime/]),
+    // ...
+  ],
+  // ...
+};
+```
+
+#### `new ModuleScopePlugin(appSrc: string | string[], allowedFiles?: string[])`
+
+This webpack plugin ensures that relative imports from app's source directories don't reach outside of it.
+
+```js
+var path = require('path');
+var ModuleScopePlugin = require('react-dev-utils/ModuleScopePlugin');
+
+module.exports = {
+  // ...
+  resolve: {
+    // ...
+    plugins: [
+      new ModuleScopePlugin(paths.appSrc, [paths.appPackageJson]),
+      // ...
+    ],
+    // ...
+  },
+  // ...
+};
+```
+
+#### `new WatchMissingNodeModulesPlugin(nodeModulesPath: string)`
+
+This webpack plugin ensures `npm install <library>` forces a project rebuild.<br>
+We’re not sure why this isn't webpack's default behavior.<br>
+See [#186](https://github.com/facebook/create-react-app/issues/186) for details.
+
+```js
+var path = require('path');
+var WatchMissingNodeModulesPlugin = require('react-dev-utils/WatchMissingNodeModulesPlugin');
+
+// webpack config
+module.exports = {
+  // ...
+  plugins: [
+    // ...
+    // If you require a missing module and then `npm install` it, you still have
+    // to restart the development server for webpack to discover it. This plugin
+    // makes the discovery automatic so you don't have to restart.
+    // See https://github.com/facebook/create-react-app/issues/186
+    new WatchMissingNodeModulesPlugin(path.resolve('node_modules')),
+  ],
+  // ...
+};
+```
+
+#### `checkRequiredFiles(files: Array<string>): boolean`
+
+Makes sure that all passed files exist.<br>
+Filenames are expected to be absolute.<br>
+If a file is not found, prints a warning message and returns `false`.
+
+```js
+var path = require('path');
+var checkRequiredFiles = require('react-dev-utils/checkRequiredFiles');
+
+if (
+  !checkRequiredFiles([
+    path.resolve('public/index.html'),
+    path.resolve('src/index.js'),
+  ])
+) {
+  process.exit(1);
+}
+```
+
+#### `clearConsole(): void`
+
+Clears the console, hopefully in a cross-platform way.
+
+```js
+var clearConsole = require('react-dev-utils/clearConsole');
+
+clearConsole();
+console.log('Just cleared the screen!');
+```
+
+#### `eslintFormatter(results: Object): string`
+
+This is our custom ESLint formatter that integrates well with Create React App console output.<br>
+You can use the default one instead if you prefer so.
+
+```js
+const eslintFormatter = require('react-dev-utils/eslintFormatter');
+
+// In your webpack config:
+// ...
+module: {
+  rules: [
+    {
+      test: /\.(js|jsx)$/,
+      include: paths.appSrc,
+      enforce: 'pre',
+      use: [
+        {
+          loader: 'eslint-loader',
+          options: {
+            // Pass the formatter:
+            formatter: eslintFormatter,
+          },
+        },
+      ],
+    },
+  ];
+}
+```
+
+#### `FileSizeReporter`
+
+##### `measureFileSizesBeforeBuild(buildFolder: string): Promise<OpaqueFileSizes>`
+
+Captures JS and CSS asset sizes inside the passed `buildFolder`. Save the result value to compare it after the build.
+
+##### `printFileSizesAfterBuild(webpackStats: WebpackStats, previousFileSizes: OpaqueFileSizes, buildFolder: string, maxBundleGzipSize?: number, maxChunkGzipSize?: number)`
+
+Prints the JS and CSS asset sizes after the build, and includes a size comparison with `previousFileSizes` that were captured earlier using `measureFileSizesBeforeBuild()`. `maxBundleGzipSize` and `maxChunkGzipSizemay` may optionally be specified to display a warning when the main bundle or a chunk exceeds the specified size (in bytes).
+
+```js
+var {
+  measureFileSizesBeforeBuild,
+  printFileSizesAfterBuild,
+} = require('react-dev-utils/FileSizeReporter');
+
+measureFileSizesBeforeBuild(buildFolder).then(previousFileSizes => {
+  return cleanAndRebuild().then(webpackStats => {
+    printFileSizesAfterBuild(webpackStats, previousFileSizes, buildFolder);
+  });
+});
+```
+
+#### `formatWebpackMessages({errors: Array<string>, warnings: Array<string>}): {errors: Array<string>, warnings: Array<string>}`
+
+Extracts and prettifies warning and error messages from webpack [stats](https://github.com/webpack/docs/wiki/node.js-api#stats) object.
+
+```js
+var webpack = require('webpack');
+var config = require('../config/webpack.config.dev');
+var formatWebpackMessages = require('react-dev-utils/formatWebpackMessages');
+
+var compiler = webpack(config);
+
+compiler.hooks.invalid.tap('invalid', function() {
+  console.log('Compiling...');
+});
+
+compiler.hooks.done.tap('done', function(stats) {
+  var rawMessages = stats.toJson({}, true);
+  var messages = formatWebpackMessages(rawMessages);
+  if (!messages.errors.length && !messages.warnings.length) {
+    console.log('Compiled successfully!');
+  }
+  if (messages.errors.length) {
+    console.log('Failed to compile.');
+    messages.errors.forEach(e => console.log(e));
+    return;
+  }
+  if (messages.warnings.length) {
+    console.log('Compiled with warnings.');
+    messages.warnings.forEach(w => console.log(w));
+  }
+});
+```
+
+#### `printBuildError(error: Object): void`
+
+Prettify some known build errors.
+Pass an Error object to log a prettified error message in the console.
+
+```
+  const printBuildError = require('react-dev-utils/printBuildError')
+  try {
+    build()
+  } catch(e) {
+    printBuildError(e) // logs prettified message
+  }
+```
+
+#### `getProcessForPort(port: number): string`
+
+Finds the currently running process on `port`.
+Returns a string containing the name and directory, e.g.,
+
+```
+create-react-app
+in /Users/developer/create-react-app
+```
+
+```js
+var getProcessForPort = require('react-dev-utils/getProcessForPort');
+
+getProcessForPort(3000);
+```
+
+#### `launchEditor(fileName: string, lineNumber: number): void`
+
+On macOS, tries to find a known running editor process and opens the file in it. It can also be explicitly configured by `REACT_EDITOR`, `VISUAL`, or `EDITOR` environment variables. For example, you can put `REACT_EDITOR=atom` in your `.env.local` file, and Create React App will respect that.
+
+#### `noopServiceWorkerMiddleware(servedPath: string): ExpressMiddleware`
+
+Returns Express middleware that serves a `${servedPath}/service-worker.js` that resets any previously set service worker configuration. Useful for development.
+
+#### `redirectServedPathMiddleware(servedPath: string): ExpressMiddleware`
+
+Returns Express middleware that redirects to `${servedPath}/${req.path}`, if `req.url`
+does not start with `servedPath`. Useful for development.
+
+#### `openBrowser(url: string): boolean`
+
+Attempts to open the browser with a given URL.<br>
+On Mac OS X, attempts to reuse an existing Chrome tab via AppleScript.<br>
+Otherwise, falls back to [opn](https://github.com/sindresorhus/opn) behavior.
+
+```js
+var path = require('path');
+var openBrowser = require('react-dev-utils/openBrowser');
+
+if (openBrowser('http://localhost:3000')) {
+  console.log('The browser tab has been opened!');
+}
+```
+
+#### `printHostingInstructions(appPackage: Object, publicUrl: string, publicPath: string, buildFolder: string, useYarn: boolean): void`
+
+Prints hosting instructions after the project is built.
+
+Pass your parsed `package.json` object as `appPackage`, your URL where you plan to host the app as `publicUrl`, `output.publicPath` from your webpack configuration as `publicPath`, the `buildFolder` name, and whether to `useYarn` in instructions.
+
+```js
+const appPackage = require(paths.appPackageJson);
+const publicUrl = paths.publicUrlOrPath;
+const publicPath = config.output.publicPath;
+printHostingInstructions(appPackage, publicUrl, publicPath, 'build', true);
+```
+
+#### `WebpackDevServerUtils`
+
+##### `choosePort(host: string, defaultPort: number): Promise<number | null>`
+
+Returns a Promise resolving to either `defaultPort` or next available port if the user confirms it is okay to do. If the port is taken and the user has refused to use another port, or if the terminal is not interactive and can’t present user with the choice, resolves to `null`.
+
+##### `createCompiler(args: Object): WebpackCompiler`
+
+Creates a webpack compiler instance for WebpackDevServer with built-in helpful messages.
+
+The `args` object accepts a number of properties:
+
+- **appName** `string`: The name that will be printed to the terminal.
+- **config** `Object`: The webpack configuration options to be provided to the webpack constructor.
+- **devSocket** `Object`: Required if `useTypeScript` is `true`. This object should include `errors` and `warnings` which are functions accepting an array of errors or warnings emitted by the type checking. This is useful when running `fork-ts-checker-webpack-plugin` with `async: true` to report errors that are emitted after the webpack build is complete.
+- **urls** `Object`: To provide the `urls` argument, use `prepareUrls()` described below.
+- **useYarn** `boolean`: If `true`, yarn instructions will be emitted in the terminal instead of npm.
+- **useTypeScript** `boolean`: If `true`, TypeScript type checking will be enabled. Be sure to provide the `devSocket` argument above if this is set to `true`.
+- **tscCompileOnError** `boolean`: If `true`, errors in TypeScript type checking will not prevent start script from running app, and will not cause build script to exit unsuccessfully. Also downgrades all TypeScript type checking error messages to warning messages.
+- **webpack** `function`: A reference to the webpack constructor.
+
+##### `prepareProxy(proxySetting: string, appPublicFolder: string, servedPathname: string): Object`
+
+Creates a WebpackDevServer `proxy` configuration object from the `proxy` setting in `package.json`.
+
+##### `prepareUrls(protocol: string, host: string, port: number, pathname: string = '/'): Object`
+
+Returns an object with local and remote URLs for the development server. Pass this object to `createCompiler()` described above.
+
+#### `webpackHotDevClient`
+
+This is an alternative client for [WebpackDevServer](https://github.com/webpack/webpack-dev-server) that shows a syntax error overlay.
+
+It currently supports only webpack 3.x.
+
+```js
+// webpack development config
+module.exports = {
+  // ...
+  entry: [
+    // You can replace the line below with these two lines if you prefer the
+    // stock client:
+    // require.resolve('webpack-dev-server/client') + '?/',
+    // require.resolve('webpack/hot/dev-server'),
+    'react-dev-utils/webpackHotDevClient',
+    'src/index',
+  ],
+  // ...
+};
+```
+
+#### `getCSSModuleLocalIdent(context: Object, localIdentName: String, localName: String, options: Object): string`
+
+Creates a class name for CSS Modules that uses either the filename or folder name if named `index.module.css`.
+
+For `MyFolder/MyComponent.module.css` and class `MyClass` the output will be `MyComponent.module_MyClass__[hash]`
+For `MyFolder/index.module.css` and class `MyClass` the output will be `MyFolder_MyClass__[hash]`
+
+```js
+const getCSSModuleLocalIdent = require('react-dev-utils/getCSSModuleLocalIdent');
+
+// In your webpack config:
+// ...
+module: {
+  rules: [
+    {
+      test: /\.module\.css$/,
+      use: [
+        require.resolve('style-loader'),
+        {
+          loader: require.resolve('css-loader'),
+          options: {
+            importLoaders: 1,
+            modules: {
+              getLocalIdent: getCSSModuleLocalIdent,
+            },
+          },
+        },
+        {
+          loader: require.resolve('postcss-loader'),
+          options: postCSSLoaderOptions,
+        },
+      ],
+    },
+  ];
+}
+```
+
+#### `getCacheIdentifier(environment: string, packages: string[]): string`
+
+Returns a cache identifier (string) consisting of the specified environment and related package versions, e.g.,
+
+```js
+var getCacheIdentifier = require('react-dev-utils/getCacheIdentifier');
+
+getCacheIdentifier('prod', ['react-dev-utils', 'chalk']); // # => 'prod:react-dev-utils@5.0.0:chalk@3.0.0'
+```

+
+> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+<img src="https://cdn.rawgit.com/chalk/ansi-styles/8261697c95bf34b6c7767e2cbe9941a851d59385/screenshot.svg" width="900">
+
+
+## Install
+
+```
+$ npm install ansi-styles
+```
+
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+//       may be degraded to fit that color palette. This means terminals
+//       that do not support 16 million colors will best-match the
+//       original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#ABCDEF') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(Not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(Not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `gray` ("bright black")
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright`
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+
+The config to share target browsers and Node.js versions between different
+front-end tools. It is used in:
+
+* [Autoprefixer]
+* [Babel]
+* [postcss-preset-env]
+* [eslint-plugin-compat]
+* [stylelint-no-unsupported-browser-features]
+* [postcss-normalize]
+* [obsolete-webpack-plugin]
+
+All tools will find target browsers automatically,
+when you add the following to `package.json`:
+
+```json
+  "browserslist": [
+    "defaults",
+    "not IE 11",
+    "not IE_Mob 11",
+    "maintained node versions"
+  ]
+```
+
+Or in `.browserslistrc` config:
+
+```yaml
+# Browsers that we support
+
+defaults
+not IE 11
+not IE_Mob 11
+maintained node versions
+```
+
+Developers set their version lists using queries like `last 2 versions`
+to be free from updating versions manually.
+Browserslist will use [`caniuse-lite`] with [Can I Use] data for this queries.
+
+Browserslist will take queries from tool option,
+`browserslist` config, `.browserslistrc` config,
+`browserslist` section in `package.json` or environment variables.
+
+[Browserslist Example] shows how every tool uses Browserslist.

+## Tools
+
+* [`browserl.ist`](https://browserl.ist/) is an online tool to check
+  what browsers will be selected by some query.
+* [`browserslist-ga`] and [`browserslist-ga-export`] download your website
+  browsers statistics to use it in `> 0.5% in my stats` query.
+* [`browserslist-useragent-regexp`] compiles Browserslist query to a RegExp
+  to test browser useragent.
+* [`browserslist-useragent-ruby`] is a Ruby library to checks browser
+  by user agent string to match Browserslist.
+* [`browserslist-browserstack`] runs BrowserStack tests for all browsers
+  in Browserslist config.
+* [`browserslist-adobe-analytics`] use Adobe Analytics data to target browsers.
+* [`caniuse-api`] returns browsers which support some specific feature.
+* Run `npx browserslist` in your project directory to see project’s
+  target browsers. This CLI tool is built-in and available in any project
+  with Autoprefixer.

+
+
+## Best Practices
+
+* There is a `defaults` query, which gives a reasonable configuration
+  for most users:
+
+  ```json
+    "browserslist": [
+      "defaults"
+    ]
+  ```
+
+* If you want to change the default set of browsers, we recommend combining
+  `last 2 versions`, `not dead` with a usage number like `> 0.2%`. This is
+  because `last n versions` on its own does not add popular old versions, while
+  only using a percentage above `0.2%` will in the long run make popular
+  browsers even more popular. We might run into a monopoly and stagnation
+  situation, as we had with Internet Explorer 6. Please use this setting
+  with caution.
+* Select browsers directly (`last 2 Chrome versions`) only if you are making
+  a web app for a kiosk with one browser. There are a lot of browsers
+  on the market. If you are making general web app you should respect
+  browsers diversity.
+* Don’t remove browsers just because you don’t know them. Opera Mini has
+  100 million users in Africa and it is more popular in the global market
+  than Microsoft Edge. Chinese QQ Browsers has more market share than Firefox
+  and desktop Safari combined.
+
+
+## Browsers Data Updating
+
+`npx browserslist@latest --update-db` updates `caniuse-lite` version
+in your npm, yarn or pnpm lock file.
+
+You need to do it regularly for two reasons:
+
+1. To use the latest browser’s versions and statistics in queries like
+   `last 2 versions` or `>1%`. For example, if you created your project
+   2 years ago and did not update your dependencies, `last 1 version`
+   will return 2 year old browsers.
+2. `caiuse-lite` deduplication: to synchronize version in different tools.
+
+> What is deduplication?
+
+Due to how npm architecture is setup, you may have a situation
+where you have multiple versions of a single dependency required.
+
+Imagine you begin a project, and you add `autoprefixer` as a dependency.
+npm looks for the latest `caniuse-lite` version (1.0.30000700) and adds it to
+`package-lock.json` under `autoprefixer` dependencies.
+
+A year later, you decide to add Babel. At this moment, we have a
+new version of `canuse-lite` (1.0.30000900). npm took the latest version
+and added it to your lock file under `@babel/preset-env` dependencies.
+
+Now your lock file looks like this:
+
+```ocaml
+autoprefixer 7.1.4
+  browserslist 3.1.1
+    caniuse-lite 1.0.30000700
+@babel/preset-env 7.10.0
+  browserslist 4.13.0
+    caniuse-lite 1.0.30000900
+```
+
+As you can see, we now have two versions of `caniuse-lite` installed.
+
+
+## Queries
+
+Browserslist will use browsers and Node.js versions query
+from one of these sources:
+
+1. `browserslist` key in `package.json` file in current or parent directories.
+   **We recommend this way.**
+2. `.browserslistrc` config file in current or parent directories.
+3. `browserslist` config file in current or parent directories.
+4. `BROWSERSLIST` environment variable.
+5. If the above methods did not produce a valid result
+   Browserslist will use defaults:
+   `> 0.5%, last 2 versions, Firefox ESR, not dead`.
+
+
+### Query Composition
+
+An `or` combiner can use the keyword `or` as well as `,`.
+`last 1 version or > 1%` is equal to `last 1 version, > 1%`.
+
+`and` query combinations are also supported to perform an
+intersection of all the previous queries:
+`last 1 version or chrome > 75 and > 1%` will select
+(`browser last version` or `Chrome since 76`) and `more than 1% marketshare`.
+
+There is 3 different ways to combine queries as depicted below. First you start
+with a single query and then we combine the queries to get our final list.
+
+Obviously you can *not* start with a `not` combiner, since there is no left-hand
+side query to combine it with. The left-hand is always resolved as `and`
+combiner even if `or` is used (this is an API implementation specificity).
+
+| Query combiner type | Illustration | Example |
+| ------------------- | :----------: | ------- |
+|`or`/`,` combiner <br> (union) | ![Union of queries](img/union.svg)  | `> .5% or last 2 versions` <br> `> .5%, last 2 versions` |
+| `and` combiner <br> (intersection) | ![intersection of queries](img/intersection.svg) | `> .5% and last 2 versions` |
+| `not` combiner <br> (relative complement) | ![Relative complement of queries](img/complement.svg) | All those three are equivalent to the first one <br> `> .5% and not last 2 versions` <br> `> .5% or not last 2 versions` <br> `> .5%, not last 2 versions` |
+
+_A quick way to test your query is to do `npx browserslist '> 0.5%, not IE 11'`
+in your terminal._
+
+### Full List
+
+You can specify the browser and Node.js versions by queries (case insensitive):
+
+* `defaults`: Browserslist’s default browsers
+  (`> 0.5%, last 2 versions, Firefox ESR, not dead`).
+* `> 5%`: browsers versions selected by global usage statistics.
+  `>=`, `<` and `<=` work too.
+  * `> 5% in US`: uses USA usage statistics.
+    It accepts [two-letter country code].
+  * `> 5% in alt-AS`: uses Asia region usage statistics.
+    List of all region codes can be found at [`caniuse-lite/data/regions`].
+  * `> 5% in my stats`: uses [custom usage data].
+  * `> 5% in browserslist-config-mycompany stats`: uses [custom usage data]
+    from `browserslist-config-mycompany/browserslist-stats.json`.
+  * `cover 99.5%`: most popular browsers that provide coverage.
+  * `cover 99.5% in US`: same as above, with [two-letter country code].
+  * `cover 99.5% in my stats`: uses [custom usage data].
+* `dead`: browsers without official support or updates for 24 months.
+  Right now it is `IE 10`, `IE_Mob 11`, `BlackBerry 10`, `BlackBerry 7`,
+  `Samsung 4` and `OperaMobile 12.1`.
+* `last 2 versions`: the last 2 versions for *each* browser.
+  * `last 2 Chrome versions`: the last 2 versions of Chrome browser.
+  * `last 2 major versions` or `last 2 iOS major versions`:
+    all minor/patch releases of last 2 major versions.
+* `node 10` and `node 10.4`: selects latest Node.js `10.x.x`
+  or `10.4.x` release.
+  * `current node`: Node.js version used by Browserslist right now.
+  * `maintained node versions`: all Node.js versions, which are [still maintained]
+    by Node.js Foundation.
+* `iOS 7`: the iOS browser version 7 directly.
+  * `Firefox > 20`: versions of Firefox newer than 20.
+    `>=`, `<` and `<=` work too. It also works with Node.js.
+  * `ie 6-8`: selects an inclusive range of versions.
+  * `Firefox ESR`: the latest [Firefox ESR] version.
+  * `PhantomJS 2.1` and `PhantomJS 1.9`: selects Safari versions similar
+    to PhantomJS runtime.
+* `extends browserslist-config-mycompany`: take queries from
+  `browserslist-config-mycompany` npm package.
+* `supports es6-module`: browsers with support for specific features.
+  `es6-module` here is the `feat` parameter at the URL of the [Can I Use]
+  page. A list of all available features can be found at
+  [`caniuse-lite/data/features`].
+* `since 2015` or `last 2 years`: all versions released since year 2015
+  (also `since 2015-03` and `since 2015-03-10`).
+* `unreleased versions` or `unreleased Chrome versions`:
+  alpha and beta versions.
+* `not ie <= 8`: exclude browsers selected by previous queries.
+
+You can add `not ` to any query.

+
+
+## Config File
+
+### `package.json`
+
+If you want to reduce config files in project root, you can specify
+browsers in `package.json` with `browserslist` key:
+
+```json
+{
+  "private": true,
+  "dependencies": {
+    "autoprefixer": "^6.5.4"
+  },
+  "browserslist": [
+    "last 1 version",
+    "> 1%",
+    "IE 10"
+  ]
+}
+```
+
+
+### `.browserslistrc`
+
+Separated Browserslist config should be named `.browserslistrc`
+and have browsers queries split by a new line.
+Each line is combined with the `or` combiner. Comments starts with `#` symbol:
+
+```yaml
+# Browsers that we support
+
+last 1 version
+> 1%
+IE 10 # sorry
+```
+
+Browserslist will check config in every directory in `path`.
+So, if tool process `app/styles/main.css`, you can put config to root,
+`app/` or `app/styles`.
+
+You can specify direct path in `BROWSERSLIST_CONFIG` environment variables.
+
+
+## Shareable Configs
+
+You can use the following query to reference an exported Browserslist config
+from another package:
+
+```json
+  "browserslist": [
+    "extends browserslist-config-mycompany"
+  ]
+```
+
+For security reasons, external configuration only supports packages that have
+the `browserslist-config-` prefix. npm scoped packages are also supported, by
+naming or prefixing the module with `@scope/browserslist-config`, such as
+`@scope/browserslist-config` or `@scope/browserslist-config-mycompany`.
+
+If you don’t accept Browserslist queries from users, you can disable the
+validation by using the or `BROWSERSLIST_DANGEROUS_EXTEND` environment variable
+or `dangerousExtend` option.
+
+```sh
+BROWSERSLIST_DANGEROUS_EXTEND=1 npx webpack
+```
+
+Because this uses `npm`'s resolution, you can also reference specific files
+in a package:
+
+```json
+  "browserslist": [
+    "extends browserslist-config-mycompany/desktop",
+    "extends browserslist-config-mycompany/mobile"
+  ]
+```
+
+When writing a shared Browserslist package, just export an array.
+`browserslist-config-mycompany/index.js`:
+
+```js
+module.exports = [
+  'last 1 version',
+  '> 1%',
+  'ie 10'
+]
+```
+
+You can also include a `browserslist-stats.json` file as part of your shareable
+config at the root and query it using
+`> 5% in browserslist-config-mycompany stats`. It uses the same format
+as `extends` and the `dangerousExtend` property as above.
+
+You can export configs for different environments and select environment
+by `BROWSERSLIST_ENV` or `env` option in your tool:
+
+```js
+module.exports = {
+  development: [
+    'last 1 version'
+  ],
+  production: [
+    'last 1 version',
+    '> 1%',
+    'ie 10'
+  ]
+}
+```
+
+
+## Configuring for Different Environments
+
+You can also specify different browser queries for various environments.
+Browserslist will choose query according to `BROWSERSLIST_ENV` or `NODE_ENV`
+variables. If none of them is declared, Browserslist will firstly look
+for `production` queries and then use defaults.
+
+In `package.json`:
+
+```js
+  "browserslist": {
+    "production": [
+      "> 1%",
+      "ie 10"
+    ],
+    "modern": [
+      "last 1 chrome version",
+      "last 1 firefox version"
+    ],
+    "ssr": [
+      "node 12"
+    ]
+  }
+```
+
+In `.browserslistrc` config:
+
+```ini
+[production]

+
+
+## Custom Usage Data
+
+If you have a website, you can query against the usage statistics of your site.
+[`browserslist-ga`] will ask access to Google Analytics and then generate
+`browserslist-stats.json`:
+
+```
+npx browserslist-ga
+```
+
+Or you can use [`browserslist-ga-export`] to convert Google Analytics data without giving a password for Google account.
+
+You can generate usage statistics file by any other method. File format should
+be like:
+
+```js
+{
+  "ie": {
+    "6": 0.01,
+    "7": 0.4,
+    "8": 1.5
+  },
+  "chrome": {
+    …
+  },
+  …
+}
+```
+
+Note that you can query against your custom usage data while also querying
+against global or regional data. For example, the query
+`> 1% in my stats, > 5% in US, 10%` is permitted.

+[`browserslist-ga-export`]: https://github.com/browserslist/browserslist-ga-export
+[`browserslist-ga`]:        https://github.com/browserslist/browserslist-ga
+[Can I Use]:                https://caniuse.com/
+
+
+## JS API
+
+```js
+const browserslist = require('browserslist')
+
+// Your CSS/JS build tool code
+function process (source, opts) {
+  const browsers = browserslist(opts.overrideBrowserslist, {
+    stats: opts.stats,
+    path:  opts.file,
+    env:   opts.env
+  })
+  // Your code to add features for selected browsers
+}
+```
+
+Queries can be a string `"> 1%, IE 10"`
+or an array `['> 1%', 'IE 10']`.
+
+If a query is missing, Browserslist will look for a config file.
+You can provide a `path` option (that can be a file) to find the config file
+relatively to it.
+
+Options:
+
+* `path`: file or a directory path to look for config file. Default is `.`.
+* `env`: what environment section use from config. Default is `production`.
+* `stats`: custom usage statistics data.
+* `config`: path to config if you want to set it manually.
+* `ignoreUnknownVersions`: do not throw on direct query (like `ie 12`).
+  Default is `false.`
+* `dangerousExtend`: Disable security checks for `extend` query.
+  Default is `false.`
+* `mobileToDesktop`: Use desktop browsers if Can I Use doesn’t have data
+  about this mobile version. For instance, Browserslist will return
+  `chrome 20` on `and_chr 20` query (Can I Use has only data only about
+  latest versions of mobile browsers). Default is `false`.
+
+For non-JS environment and debug purpose you can use CLI tool:
+
+```sh
+browserslist "> 1%, IE 10"
+```
+
+You can get total users coverage for selected browsers by JS API:
+
+```js
+browserslist.coverage(browserslist('> 1%'))
+//=> 81.4
+```
+
+```js
+browserslist.coverage(browserslist('> 1% in US'), 'US')
+//=> 83.1
+```
+
+```js
+browserslist.coverage(browserslist('> 1% in my stats'), 'my stats')
+//=> 83.1
+```
+
+```js
+browserslist.coverage(browserslist('> 1% in my stats', { stats }), stats)
+//=> 82.2
+```
+
+Or by CLI:
+
+```sh
+$ browserslist --coverage "> 1%"
+These browsers account for 81.4% of all users globally
+```
+
+```sh
+$ browserslist --coverage=US "> 1% in US"
+These browsers account for 83.1% of all users in the US
+```
+
+```sh
+$ browserslist --coverage "> 1% in my stats"
+These browsers account for 83.1% of all users in custom statistics
+```
+
+```sh
+$ browserslist --coverage "> 1% in my stats" --stats=./stats.json
+These browsers account for 83.1% of all users in custom statistics
+```
+
+
+## Environment Variables
+
+If a tool uses Browserslist inside, you can change the Browserslist settings
+with [environment variables]:
+
+* `BROWSERSLIST` with browsers queries.
+
+   ```sh
+  BROWSERSLIST="> 5%" npx webpack
+   ```
+
+* `BROWSERSLIST_CONFIG` with path to config file.
+
+   ```sh
+  BROWSERSLIST_CONFIG=./config/browserslist npx webpack
+   ```
+
+* `BROWSERSLIST_ENV` with environments string.
+
+   ```sh
+  BROWSERSLIST_ENV="development" npx webpack
+   ```
+
+* `BROWSERSLIST_STATS` with path to the custom usage data
+  for `> 1% in my stats` query.
+
+   ```sh
+  BROWSERSLIST_STATS=./config/usage_data.json npx webpack
+   ```
+
+* `BROWSERSLIST_DISABLE_CACHE` if you want to disable config reading cache.
+
+   ```sh
+  BROWSERSLIST_DISABLE_CACHE=1 npx webpack
+   ```
+
+* `BROWSERSLIST_DANGEROUS_EXTEND` to disable security shareable config
+  name check.
+
+   ```sh
+  BROWSERSLIST_DANGEROUS_EXTEND=1 npx webpack
+   ```
+
+[environment variables]: https://en.wikipedia.org/wiki/Environment_variable
+
+
+## Cache
+
+Browserslist caches the configuration it reads from `package.json` and
+`browserslist` files, as well as knowledge about the existence of files,
+for the duration of the hosting process.
+
+To clear these caches, use:
+
+```js
+browserslist.clearCaches()
+```
+
+To disable the caching altogether, set the `BROWSERSLIST_DISABLE_CACHE`
+environment variable.

+
+
+## Usage
+
+```js
+const chalk = require('chalk');
+
+console.log(chalk.blue('Hello world!'));
+```
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+const chalk = require('chalk');
+const log = console.log;
+
+// Combine styled and normal strings
+log(chalk.blue('Hello') + ' World' + chalk.red('!'));
+
+// Compose multiple styles using the chainable API
+log(chalk.blue.bgRed.bold('Hello world!'));
+
+// Pass in multiple arguments
+log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
+
+// Nest styles
+log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
+
+// Nest styles of the same type even (color, underline, background)
+log(chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+));
+
+// ES2015 template literal
+log(`
+CPU: ${chalk.red('90%')}
+RAM: ${chalk.green('40%')}
+DISK: ${chalk.yellow('70%')}
+`);
+
+// ES2015 tagged template literal
+log(chalk`
+CPU: {red ${cpu.totalPercent}%}
+RAM: {green ${ram.used / ram.total * 100}%}
+DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
+`);
+
+// Use RGB colors in terminal emulators that support it.
+log(chalk.keyword('orange')('Yay for orange colored text!'));
+log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
+log(chalk.hex('#DEADED').bold('Bold gray!'));
+```
+
+Easily define your own themes:
+
+```js
+const chalk = require('chalk');
+
+const error = chalk.bold.red;
+const warning = chalk.keyword('orange');
+
+console.log(error('Error!'));
+console.log(warning('Warning!'));
+```
+
+Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
+
+```js
+const name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> 'Hello Sindre'
+```
+
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.enabled
+
+Color support is automatically detected, as is the level (see `chalk.level`). However, if you'd like to simply enable/disable Chalk, you can do so via the `.enabled` property.
+
+Chalk is enabled by default unless explicitly disabled via the constructor or `chalk.level` is `0`.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.constructor({enabled: false});
+```
+
+### chalk.level
+
+Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.constructor({level: 0});
+```
+
+Levels are as follows:
+
+0. All colors disabled
+1. Basic color support (16 colors)
+2. 256 color support
+3. Truecolor support (16 million colors)
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
+

+
+
+## Tagged template literal
+
+Chalk can be used as a [tagged template literal](http://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
+
+```js
+const chalk = require('chalk');
+
+const miles = 18;
+const calculateFeet = miles => miles * 5280;
+
+console.log(chalk`
+  There are {bold 5280 feet} in a mile.
+  In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
+`);
+```
+
+Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
+
+Template styles are chained exactly like normal Chalk styles. The following two statements are equivalent:
+
+```js
+console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
+console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
+```
+
+Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
+
+All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
+
+
+## 256 and Truecolor color support
+
+Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
+
+Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
+
+Examples:
+
+- `chalk.hex('#DEADED').underline('Hello, world!')`
+- `chalk.keyword('orange')('Some orange text')`
+- `chalk.rgb(15, 100, 204).inverse('Hello!')`
+
+Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
+
+- `chalk.bgHex('#DEADED').underline('Hello, world!')`
+- `chalk.bgKeyword('orange')('Some orange text')`
+- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
+
+The following color models can be used:
+
+- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
+- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
+- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
+- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
+- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
+- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model)  - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
+- `ansi16`
+- `ansi256`
+
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [`cmder`](http://cmder.net/) instead of `cmd.exe`.
+
+
+## Origin story
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.

+# color-convert
+
+[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](https://travis-ci.org/Qix-/color-convert)
+
+Color-convert is a color conversion library for JavaScript and node.
+It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hsl(140, 200, 100);             // [96, 48, 59]
+convert.keyword.rgb('blue');                // [0, 0, 255]
+
+var rgbChannels = convert.rgb.channels;     // 3
+var cmykChannels = convert.cmyk.channels;   // 4
+var ansiChannels = convert.ansi16.channels; // 1
+```
+
+# Install
+
+```console
+$ npm install color-convert
+```
+
+# API
+
+Simply get the property of the _from_ and _to_ conversion that you're looking for.
+
+All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
+
+All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
+
+```js
+var convert = require('color-convert');
+
+// Hex to LAB
+convert.hex.lab('DEADBF');         // [ 76, 21, -2 ]
+convert.hex.lab.raw('DEADBF');     // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
+
+// RGB to CMYK
+convert.rgb.cmyk(167, 255, 4);     // [ 35, 0, 98, 0 ]
+convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
+```
+
+### Arrays
+All functions that accept multiple arguments also support passing an array.
+
+Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hex(123, 45, 67);      // '7B2D43'
+convert.rgb.hex([123, 45, 67]);    // '7B2D43'
+```
+
+## Routing
+
+Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
+
+Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).
+
+# Contribute
+
+If there is a new model you would like to support, or want to add a direct conversion between two existing models, please send us a pull request.

+# globby [![Build Status](https://travis-ci.org/sindresorhus/globby.svg?branch=master)](https://travis-ci.org/sindresorhus/globby)
+
+> User-friendly glob matching
+
+Based on [`fast-glob`](https://github.com/mrmlnc/fast-glob) but adds a bunch of useful features.
+
+## Features
+
+- Promise API
+- Multiple patterns
+- Negated patterns: `['foo*', '!foobar']`
+- Expands directories: `foo` → `foo/**/*`
+- Supports `.gitignore`
+
+## Install
+
+```
+$ npm install globby
+```
+
+## Usage
+
+```
+├── unicorn
+├── cake
+└── rainbow
+```
+
+```js
+const globby = require('globby');
+
+(async () => {
+	const paths = await globby(['*', '!cake']);
+
+	console.log(paths);
+	//=> ['unicorn', 'rainbow']
+})();
+```
+
+## API
+
+Note that glob patterns can only contain forward-slashes, not backward-slashes, so if you want to construct a glob pattern from path components, you need to use `path.posix.join()` instead of `path.join()`.
+
+### globby(patterns, options?)
+
+Returns a `Promise<string[]>` of matching paths.
+
+#### patterns
+
+Type: `string | string[]`
+
+See supported `minimatch` [patterns](https://github.com/isaacs/minimatch#usage).
+
+#### options
+
+Type: `object`
+
+See the [`fast-glob` options](https://github.com/mrmlnc/fast-glob#options-3) in addition to the ones below.
+
+##### expandDirectories
+
+Type: `boolean | string[] | object`\
+Default: `true`
+
+If set to `true`, `globby` will automatically glob directories for you. If you define an `Array` it will only glob files that matches the patterns inside the `Array`. You can also define an `object` with `files` and `extensions` like below:
+
+```js
+const globby = require('globby');
+
+(async () => {
+	const paths = await globby('images', {
+		expandDirectories: {
+			files: ['cat', 'unicorn', '*.jpg'],
+			extensions: ['png']
+		}
+	});
+
+	console.log(paths);
+	//=> ['cat.png', 'unicorn.png', 'cow.jpg', 'rainbow.jpg']
+})();
+```
+
+Note that if you set this option to `false`, you won't get back matched directories unless you set `onlyFiles: false`.
+
+##### gitignore
+
+Type: `boolean`\
+Default: `false`
+
+Respect ignore patterns in `.gitignore` files that apply to the globbed files.
+
+### globby.sync(patterns, options?)
+
+Returns `string[]` of matching paths.
+
+### globby.stream(patterns, options?)
+
+Returns a [`stream.Readable`](https://nodejs.org/api/stream.html#stream_readable_streams) of matching paths.
+
+Since Node.js 10, [readable streams are iterable](https://nodejs.org/api/stream.html#stream_readable_symbol_asynciterator), so you can loop over glob matches in a [`for await...of` loop](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for-await...of) like this:
+
+```js
+const globby = require('globby');
+
+(async () => {
+	for await (const path of globby.stream('*.tmp')) {
+		console.log(path);
+	}
+})();
+```
+
+### globby.generateGlobTasks(patterns, options?)
+
+Returns an `object[]` in the format `{pattern: string, options: Object}`, which can be passed as arguments to [`fast-glob`](https://github.com/mrmlnc/fast-glob). This is useful for other globbing-related packages.
+
+Note that you should avoid running the same tasks multiple times as they contain a file system cache. Instead, run this method each time to ensure file system changes are taken into consideration.
+
+### globby.hasMagic(patterns, options?)
+
+Returns a `boolean` of whether there are any special glob characters in the `patterns`.
+
+Note that the options affect the results.
+
+This function is backed by [`fast-glob`](https://github.com/mrmlnc/fast-glob#isdynamicpatternpattern-options).
+
+### globby.gitignore(options?)
+
+Returns a `Promise<(path: string) => boolean>` indicating whether a given path is ignored via a `.gitignore` file.
+
+Takes `cwd?: string` and `ignore?: string[]` as options. `.gitignore` files matched by the ignore config are not used for the resulting filter function.
+
+```js
+const {gitignore} = require('globby');
+
+(async () => {
+	const isIgnored = await gitignore();
+	console.log(isIgnored('some/file'));
+})();
+```
+
+### globby.gitignore.sync(options?)
+
+Returns a `(path: string) => boolean` indicating whether a given path is ignored via a `.gitignore` file.
+
+Takes the same options as `globby.gitignore`.
+
+## Globbing patterns
+
+Just a quick overview.
+
+- `*` matches any number of characters, but not `/`
+- `?` matches a single character, but not `/`
+- `**` matches any number of characters, including `/`, as long as it's the only thing in a path part
+- `{}` allows for a comma-separated list of "or" expressions
+- `!` at the beginning of a pattern will negate the match
+

+
+# ignore
+
+`ignore` is a manager, filter and parser which implemented in pure JavaScript according to the [.gitignore spec 2.22.1](http://git-scm.com/docs/gitignore).
+
+`ignore` is used by eslint, gitbook and [many others](https://www.npmjs.com/browse/depended/ignore).
+
+Pay **ATTENTION** that [`minimatch`](https://www.npmjs.org/package/minimatch) (which used by `fstream-ignore`) does not follow the gitignore spec.
+
+To filter filenames according to a .gitignore file, I recommend this npm package, `ignore`.
+
+To parse an `.npmignore` file, you should use `minimatch`, because an `.npmignore` file is parsed by npm using `minimatch` and it does not work in the .gitignore way.
+
+### Tested on
+
+`ignore` is fully tested, and has more than **five hundreds** of unit tests.
+
+- Linux + Node: `0.8` - `7.x`
+- Windows + Node: `0.10` - `7.x`, node < `0.10` is not tested due to the lack of support of appveyor.
+
+Actually, `ignore` does not rely on any versions of node specially.
+
+Since `4.0.0`, ignore will no longer support `node < 6` by default, to use in node < 6, `require('ignore/legacy')`. For details, see [CHANGELOG](https://github.com/kaelzhang/node-ignore/blob/master/CHANGELOG.md).

+- [Usage](#usage)
+- [`Pathname` Conventions](#pathname-conventions)
+- See Also:
+  - [`glob-gitignore`](https://www.npmjs.com/package/glob-gitignore) matches files using patterns and filters them according to gitignore rules.
+- [Upgrade Guide](#upgrade-guide)
+
+## Install
+
+```sh
+npm i ignore
+```
+
+## Usage
+
+```js
+import ignore from 'ignore'
+const ig = ignore().add(['.abc/*', '!.abc/d/'])
+```
+
+### Filter the given paths
+
+```js
+const paths = [
+  '.abc/a.js',    // filtered out
+  '.abc/d/e.js'   // included
+]
+
+ig.filter(paths)        // ['.abc/d/e.js']
+ig.ignores('.abc/a.js') // true
+```
+
+### As the filter function
+
+```js
+paths.filter(ig.createFilter()); // ['.abc/d/e.js']
+```
+
+### Win32 paths will be handled
+
+```js
+ig.filter(['.abc\\a.js', '.abc\\d\\e.js'])
+// if the code above runs on windows, the result will be
+// ['.abc\\d\\e.js']
+```
+
+## Why another ignore?
+
+- `ignore` is a standalone module, and is much simpler so that it could easy work with other programs, unlike [isaacs](https://npmjs.org/~isaacs)'s [fstream-ignore](https://npmjs.org/package/fstream-ignore) which must work with the modules of the fstream family.
+
+- `ignore` only contains utility methods to filter paths according to the specified ignore rules, so
+  - `ignore` never try to find out ignore rules by traversing directories or fetching from git configurations.
+  - `ignore` don't cares about sub-modules of git projects.
+
+- Exactly according to [gitignore man page](http://git-scm.com/docs/gitignore), fixes some known matching issues of fstream-ignore, such as:
+  - '`/*.js`' should only match '`a.js`', but not '`abc/a.js`'.
+  - '`**/foo`' should match '`foo`' anywhere.
+  - Prevent re-including a file if a parent directory of that file is excluded.
+  - Handle trailing whitespaces:
+    - `'a '`(one space) should not match `'a  '`(two spaces).
+    - `'a \ '` matches `'a  '`
+  - All test cases are verified with the result of `git check-ignore`.
+
+# Methods
+
+## .add(pattern: string | Ignore): this
+## .add(patterns: Array<string | Ignore>): this
+
+- **pattern** `String | Ignore` An ignore pattern string, or the `Ignore` instance
+- **patterns** `Array<String | Ignore>` Array of ignore patterns.
+
+Adds a rule or several rules to the current manager.
+
+Returns `this`
+
+Notice that a line starting with `'#'`(hash) is treated as a comment. Put a backslash (`'\'`) in front of the first hash for patterns that begin with a hash, if you want to ignore a file with a hash at the beginning of the filename.
+
+```js
+ignore().add('#abc').ignores('#abc')    // false
+ignore().add('\#abc').ignores('#abc')   // true
+```
+
+`pattern` could either be a line of ignore pattern or a string of multiple ignore patterns, which means we could just `ignore().add()` the content of a ignore file:
+
+```js
+ignore()
+.add(fs.readFileSync(filenameOfGitignore).toString())
+.filter(filenames)
+```
+
+`pattern` could also be an `ignore` instance, so that we could easily inherit the rules of another `Ignore` instance.
+
+## <strike>.addIgnoreFile(path)</strike>
+
+REMOVED in `3.x` for now.
+
+To upgrade `ignore@2.x` up to `3.x`, use
+
+```js
+import fs from 'fs'
+
+if (fs.existsSync(filename)) {
+  ignore().add(fs.readFileSync(filename).toString())
+}
+```
+
+instead.
+
+## .filter(paths: Array&lt;Pathname&gt;): Array&lt;Pathname&gt;
+
+```ts
+type Pathname = string
+```
+
+Filters the given array of pathnames, and returns the filtered array.
+
+- **paths** `Array.<Pathname>` The array of `pathname`s to be filtered.
+
+### `Pathname` Conventions:
+
+#### 1. `Pathname` should be a `path.relative()`d pathname
+
+`Pathname` should be a string that have been `path.join()`ed, or the return value of `path.relative()` to the current directory,
+
+```js
+// WRONG, an error will be thrown
+ig.ignores('./abc')
+
+// WRONG, for it will never happen, and an error will be thrown
+// If the gitignore rule locates at the root directory,
+// `'/abc'` should be changed to `'abc'`.
+// ```
+// path.relative('/', '/abc')  -> 'abc'
+// ```
+ig.ignores('/abc')
+
+// WRONG, that it is an absolute path on Windows, an error will be thrown
+ig.ignores('C:\\abc')
+
+// Right
+ig.ignores('abc')
+
+// Right
+ig.ignores(path.join('./abc'))  // path.join('./abc') -> 'abc'
+```
+
+In other words, each `Pathname` here should be a relative path to the directory of the gitignore rules.
+
+Suppose the dir structure is:
+
+```
+/path/to/your/repo
+    |-- a
+    |   |-- a.js
+    |
+    |-- .b
+    |
+    |-- .c
+         |-- .DS_store
+```
+
+Then the `paths` might be like this:
+
+```js
+[
+  'a/a.js'
+  '.b',
+  '.c/.DS_store'
+]
+```
+
+#### 2. filenames and dirnames
+
+`node-ignore` does NO `fs.stat` during path matching, so for the example below:
+
+```js
+// First, we add a ignore pattern to ignore a directory
+ig.add('config/')
+
+// `ig` does NOT know if 'config', in the real world,
+//   is a normal file, directory or something.
+
+ig.ignores('config')
+// `ig` treats `config` as a file, so it returns `false`
+
+ig.ignores('config/')
+// returns `true`
+```
+
+Specially for people who develop some library based on `node-ignore`, it is important to understand that.
+
+Usually, you could use [`glob`](http://npmjs.org/package/glob) with `option.mark = true` to fetch the structure of the current directory:
+
+```js
+import glob from 'glob'
+
+glob('**', {
+  // Adds a / character to directory matches.
+  mark: true
+}, (err, files) => {
+  if (err) {
+    return console.error(err)
+  }
+
+  let filtered = ignore().add(patterns).filter(files)
+  console.log(filtered)
+})
+```
+
+## .ignores(pathname: Pathname): boolean
+
+> new in 3.2.0
+
+Returns `Boolean` whether `pathname` should be ignored.
+
+```js
+ig.ignores('.abc/a.js')    // true
+```
+
+## .createFilter()
+
+Creates a filter function which could filter an array of paths with `Array.prototype.filter`.
+
+Returns `function(path)` the filter function.
+
+## .test(pathname: Pathname) since 5.0.0
+
+Returns `TestResult`
+
+```ts
+interface TestResult {
+  ignored: boolean
+  // true if the `pathname` is finally unignored by some negative pattern
+  unignored: boolean
+}
+```
+
+- `{ignored: true, unignored: false}`: the `pathname` is ignored
+- `{ignored: false, unignored: true}`: the `pathname` is unignored
+- `{ignored: false, unignored: false}`: the `pathname` is never matched by any ignore rules.
+
+## `options.ignorecase` since 4.0.0
+
+Similar as the `core.ignorecase` option of [git-config](https://git-scm.com/docs/git-config), `node-ignore` will be case insensitive if `options.ignorecase` is set to `true` (the default value), otherwise case sensitive.
+
+```js
+const ig = ignore({
+  ignorecase: false
+})
+
+ig.add('*.png')
+
+ig.ignores('*.PNG')  // false
+```
+
+## static `ignore.isPathValid(pathname): boolean` since 5.0.0
+
+Check whether the `pathname` is an valid `path.relative()`d path according to the [convention](#1-pathname-should-be-a-pathrelatived-pathname).
+
+This method is **NOT** used to check if an ignore pattern is valid.
+
+```js
+ignore.isPathValid('./foo')  // false
+```
+
+****
+
+# Upgrade Guide
+
+## Upgrade 4.x -> 5.x
+
+Since `5.0.0`, if an invalid `Pathname` passed into `ig.ignores()`, an error will be thrown, while `ignore < 5.0.0` did not make sure what the return value was, as well as
+
+```ts
+.ignores(pathname: Pathname): boolean
+
+.filter(pathnames: Array<Pathname>): Array<Pathname>
+
+.createFilter(): (pathname: Pathname) => boolean
+
+.test(pathname: Pathname): {ignored: boolean, unignored: boolean}
+```
+
+See the convention [here](#1-pathname-should-be-a-pathrelatived-pathname) for details.
+
+If there are invalid pathnames, the conversion and filtration should be done by users.
+
+```js
+import {isPathValid} from 'ignore' // introduced in 5.0.0
+
+const paths = [
+  // invalid
+  //////////////////
+  '',
+  false,
+  '../foo',
+  '.',
+  //////////////////
+
+  // valid
+  'foo'
+]
+.filter(isValidPath)
+
+ig.filter(paths)
+```
+
+## Upgrade 3.x -> 4.x
+
+Since `4.0.0`, `ignore` will no longer support node < 6, to use `ignore` in node < 6:
+
+```js
+var ignore = require('ignore/legacy')
+```
+
+## Upgrade 2.x -> 3.x
+
+- All `options` of 2.x are unnecessary and removed, so just remove them.
+- `ignore()` instance is no longer an [`EventEmitter`](nodejs.org/api/events.html), and all events are unnecessary and removed.
+- `.addIgnoreFile()` is removed, see the [.addIgnoreFile](#addignorefilepath) section for details.
