This is a [webpack](http://webpack.js.org/) plugin that simplifies creation of HTML files to serve your `webpack` bundles. This is especially useful for `webpack` bundles that include a hash in the filename which changes every compilation. You can either let the plugin generate an HTML file for you, supply
|
|
your own template using `lodash` templates or use your own loader.

<h2 align="center">Zero Config</h2>
|
|
|
|
The `html-webpack-plugin` works without configuration.
|
|
It's a great addition to the [⚙️ webpack-config-plugins](https://github.com/namics/webpack-config-plugins/blob/master/README.md#zero-config-webpack-dev-server-example).
|
|
|
|
<h2 align="center">Plugins</h2>
|
|
|
|
The `html-webpack-plugin` provides [hooks](https://github.com/jantimon/html-webpack-plugin#events) to extend it to your needs. There are already some really powerful plugins which can be integrated with zero configuration
|
|
|
|
* [webpack-subresource-integrity](https://www.npmjs.com/package/webpack-subresource-integrity) for enhanced asset security
|
|
* [appcache-webpack-plugin](https://github.com/lettertwo/appcache-webpack-plugin) for iOS and Android offline usage
|
|
* [favicons-webpack-plugin](https://github.com/jantimon/favicons-webpack-plugin) which generates favicons and icons for iOS, Android and desktop browsers
|
|
* [html-webpack-harddisk-plugin](https://github.com/jantimon/html-webpack-harddisk-plugin) can be used to always write to disk the html file, useful when webpack-dev-server / HMR are being used
|
|
* [html-webpack-inline-source-plugin](https://github.com/DustinJackson/html-webpack-inline-source-plugin) to inline your assets in the resulting HTML file
|
|
* [html-webpack-inline-svg-plugin](https://github.com/thegc/html-webpack-inline-svg-plugin) to inline SVGs in the resulting HTML file.
|
|
* [html-webpack-exclude-assets-plugin](https://github.com/jamesjieye/html-webpack-exclude-assets-plugin) for excluding assets using regular expressions
|
|
* [html-webpack-include-assets-plugin](https://github.com/jharris4/html-webpack-include-assets-plugin) for including lists of js or css file paths (such as those copied by the copy-webpack-plugin).
|
|
* [script-ext-html-webpack-plugin](https://github.com/numical/script-ext-html-webpack-plugin) to add `async`, `defer` or `module` attributes to your `<script>` elements, or even inline them
|
|
* [style-ext-html-webpack-plugin](https://github.com/numical/style-ext-html-webpack-plugin) to convert your `<link>`s to external stylesheets into `<style>` elements containing internal CSS
|
|
* [html-webpack-injector](https://github.com/thearchitgarg/html-webpack-injector) to inject chunks in `head` or `body` (different locations ) of same html document.
|
|
* [resource-hints-webpack-plugin](https://github.com/jantimon/resource-hints-webpack-plugin) to add resource hints for faster initial page loads using `<link rel='preload'>` and `<link rel='prefetch'>`
|
|
* [preload-webpack-plugin](https://github.com/GoogleChrome/preload-webpack-plugin) for automatically wiring up asynchronous (and other types) of JavaScript chunks using `<link rel='preload'>` helping with lazy-loading
|
|
* [link-media-html-webpack-plugin](https://github.com/yaycmyk/link-media-html-webpack-plugin) allows for injected stylesheet `<link />` tags to have their media attribute set automatically; useful for providing specific desktop/mobile/print etc. stylesheets that the browser will conditionally download
|
|
* [inline-chunk-manifest-html-webpack-plugin](https://github.com/jouni-kantola/inline-chunk-manifest-html-webpack-plugin) for inlining webpack's chunk manifest. Default extracts manifest and inlines in `<head>`
|
|
* [html-webpack-inline-style-plugin](https://github.com/djaax/html-webpack-inline-style-plugin) for inlining styles to HTML elements using [juice](https://github.com/Automattic/juice). Useful for email generation automatisation.
|
|
* [html-webpack-exclude-empty-assets-plugin](https://github.com/KnisterPeter/html-webpack-exclude-empty-assets-plugin) removes empty assets from being added to the html. This fixes some problems with extract-text-plugin with webpack 4.
|
|
* [webpack-concat-plugin](https://github.com/hxlniada/webpack-concat-plugin) for concat and uglify files that needn't to be webpack bundles(for legacy files) and inject to html-webpack-plugin.
|
|
* [html-webpack-link-type-plugin](https://github.com/steadyapp/html-webpack-link-type-plugin) adds a configurable mimetype to resources injected as links (such as adding type="text/css" to external stylesheets) for compatibility with "strict mode".
|
|
* [csp-html-webpack-plugin](https://github.com/slackhq/csp-html-webpack-plugin) to add [Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy) meta tags to the HTML output
|
|
* [webpack-nomodule-plugin](https://github.com/swimmadude66/webpack-nomodule-plugin) allows you to add a `nomodule` attribute to specific injected scripts, which prevents the scripts from being loaded by newer browsers. Good for limiting loads of polyfills.
|
|
* [html-webpack-skip-assets-plugin](https://github.com/swimmadude66/html-webpack-skip-assets-plugin) Skip adding certain output files to the html file. Built as a drop-in replacement for [html-webpack-exclude-assets-plugin](https://www.npmjs.com/package/html-webpack-exclude-assets-plugin) and works with newer [html-webpack-plugin](https://github.com/jantimon/html-webpack-plugin) versions
|
|
|
|
|
|
<h2 align="center">Usage</h2>
|
|
|
|
The plugin will generate an HTML5 file for you that includes all your `webpack`
|
|
bundles in the body using `script` tags. Just add the plugin to your `webpack`
|
|
config as follows:
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
const HtmlWebpackPlugin = require('html-webpack-plugin')
|
|
|
|
module.exports = {
|
|
entry: 'index.js',
|
|
output: {
|
|
path: __dirname + '/dist',
|
|
filename: 'index_bundle.js'
|
|
},
|
|
plugins: [
|
|
new HtmlWebpackPlugin()
|
|
]
|
|
}
|
|
```
|
|
|
|
This will generate a file `dist/index.html` containing the following
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<meta charset="utf-8">
|
|
<title>Webpack App</title>
|
|
</head>
|
|
<body>
|
|
<script src="index_bundle.js"></script>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
If you have multiple `webpack` entry points, they will all be included with `script` tags in the generated HTML.
|
|
|
|
If you have any CSS assets in webpack's output (for example, CSS extracted with the [mini-css-extract-plugin](https://github.com/webpack-contrib/mini-css-extract-plugin))
|
|
then these will be included with `<link>` tags in the HTML head.
|
|
|
|
If you have plugins that make use of it, `html-webpack-plugin` should be ordered first before any of the integrated plugins.
|
|
|
|
<h2 align="center">Options</h2>
|
|
|
|
You can pass a hash of configuration options to `html-webpack-plugin`.
|
|
Allowed values are as follows
|
|
|
|
|Name|Type|Default|Description|
|
|
|:--:|:--:|:-----:|:----------|
|
|
|**`title`**|`{String}`|`Webpack App`|The title to use for the generated HTML document|
|
|
|**`filename`**|`{String}`|`'index.html'`|The file to write the HTML to. Defaults to `index.html`. You can specify a subdirectory here too (eg: `assets/admin.html`)|
|
|
|**`template`**|`{String}`|``|`webpack` relative or absolute path to the template. By default it will use `src/index.ejs` if it exists. Please see the [docs](https://github.com/jantimon/html-webpack-plugin/blob/master/docs/template-option.md) for details|
|
|
|**`templateContent`**|`{string\|Function\|false}`|false| Can be used instead of `template` to provide an inline template - please read the [Writing Your Own Templates](https://github.com/jantimon/html-webpack-plugin#writing-your-own-templates) section |
|
|
|**`templateParameters`**|`{Boolean\|Object\|Function}`| `false`| Allows to overwrite the parameters used in the template - see [example](https://github.com/jantimon/html-webpack-plugin/tree/master/examples/template-parameters) |
|
|
|**`inject`**|`{Boolean\|String}`|`true`|`true \|\| 'head' \|\| 'body' \|\| false` Inject all assets into the given `template` or `templateContent`. When passing `true` or `'body'` all javascript resources will be placed at the bottom of the body element. `'head'` will place the scripts in the head element - see the [inject:false example](https://github.com/jantimon/html-webpack-plugin/tree/master/examples/custom-insertion-position)|
|
|
|**`publicPath`**|`{String|'auto'}`|`'auto'`|The publicPath used for script and link tags|
|
|
|**`scriptLoading`**|`{'blocking'\|'defer'}`|`'blocking'`| Modern browsers support non blocking javascript loading (`'defer'`) to improve the page startup performance. |
|
|
|**`favicon`**|`{String}`|``|Adds the given favicon path to the output HTML|
|
|
|**`meta`**|`{Object}`|`{}`|Allows to inject `meta`-tags. E.g. `meta: {viewport: 'width=device-width, initial-scale=1, shrink-to-fit=no'}`|
|
|
|**`base`**|`{Object\|String\|false}`|`false`|Inject a [`base`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/base) tag. E.g. `base: "https://example.com/path/page.html`|
|
|
|**`minify`**|`{Boolean\|Object}`|`true` if `mode` is `'production'`, otherwise `false`|Controls if and in what ways the output should be minified. See [minification](#minification) below for more details.|
|
|
|**`hash`**|`{Boolean}`|`false`|If `true` then append a unique `webpack` compilation hash to all included scripts and CSS files. This is useful for cache busting|
|
|
|**`cache`**|`{Boolean}`|`true`|Emit the file only if it was changed|
|
|
|**`showErrors`**|`{Boolean}`|`true`|Errors details will be written into the HTML page|
|
|
|**`chunks`**|`{?}`|`?`|Allows you to add only some chunks (e.g only the unit-test chunk)|
|
|
|**`chunksSortMode`**|`{String\|Function}`|`auto`|Allows to control how chunks should be sorted before they are included to the HTML. Allowed values are `'none' \| 'auto' \| 'manual' \| {Function}`|
|
|
|**`excludeChunks`**|`{Array.<string>}`|``|Allows you to skip some chunks (e.g don't add the unit-test chunk)|
|
|
|**`xhtml`**|`{Boolean}`|`false`|If `true` render the `link` tags as self-closing (XHTML compliant)|
|
|
|
|
Here's an example webpack config illustrating how to use these options
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
{
|
|
entry: 'index.js',
|
|
output: {
|
|
path: __dirname + '/dist',
|
|
filename: 'index_bundle.js'
|
|
},
|
|
plugins: [
|
|
new HtmlWebpackPlugin({
|
|
title: 'My App',
|
|
filename: 'assets/admin.html'
|
|
})
|
|
]
|
|
}
|
|
```
|
|
|
|
### Generating Multiple HTML Files
|
|
|
|
To generate more than one HTML file, declare the plugin more than
|
|
once in your plugins array
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
{
|
|
entry: 'index.js',
|
|
output: {
|
|
path: __dirname + '/dist',
|
|
filename: 'index_bundle.js'
|
|
},
|
|
plugins: [
|
|
new HtmlWebpackPlugin(), // Generates default index.html
|
|
new HtmlWebpackPlugin({ // Also generate a test.html
|
|
filename: 'test.html',
|
|
template: 'src/assets/test.html'
|
|
})
|
|
]
|
|
}
|
|
```
|
|
|
|
### Writing Your Own Templates
|
|
|
|
If the default generated HTML doesn't meet your needs you can supply
|
|
your own template. The easiest way is to use the `template` option and pass a custom HTML file.
|
|
The html-webpack-plugin will automatically inject all necessary CSS, JS, manifest
|
|
and favicon files into the markup.
|
|
|
|
Details of other template loaders are [documented here](https://github.com/jantimon/html-webpack-plugin/blob/master/docs/template-option.md).
|
|
|
|
```js
|
|
plugins: [
|
|
new HtmlWebpackPlugin({
|
|
title: 'Custom template',
|
|
// Load a custom template (lodash by default)
|
|
template: 'index.html'
|
|
})
|
|
]
|
|
```
|
|
|
|
**index.html**
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<meta charset="utf-8"/>
|
|
<title><%= htmlWebpackPlugin.options.title %></title>
|
|
</head>
|
|
<body>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
If you already have a template loader, you can use it to parse the template.
|
|
Please note that this will also happen if you specify the html-loader and use `.html` file as template.
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
module: {
|
|
loaders: [
|
|
{ test: /\.hbs$/, loader: "handlebars-loader" }
|
|
]
|
|
},
|
|
plugins: [
|
|
new HtmlWebpackPlugin({
|
|
title: 'Custom template using Handlebars',
|
|
template: 'index.hbs'
|
|
})
|
|
]
|
|
```
|
|
|
|
You can use the `lodash` syntax out of the box. If the `inject` feature doesn't fit your needs and you want full control over the asset placement use the [default template](https://github.com/jaketrent/html-webpack-template/blob/86f285d5c790a6c15263f5cc50fd666d51f974fd/index.html) of the [html-webpack-template project](https://github.com/jaketrent/html-webpack-template) as a starting point for writing your own.
|
|
|
|
The following variables are available in the template by default (you can extend them using the `templateParameters` option):
|
|
|
|
- `htmlWebpackPlugin`: data specific to this plugin
|
|
|
|
- `htmlWebpackPlugin.options`: the options hash that was passed to
|
|
the plugin. In addition to the options actually used by this plugin,
|
|
you can use this hash to pass arbitrary data through to your template.
|
|
|
|
- `htmlWebpackPlugin.tags`: the prepared `headTags` and `bodyTags` Array to render the `<base>`, `<meta>`, `<script>` and `<link>` tags.
|
|
Can be used directly in templates and literals. For example:
|
|
```html
|
|
<html>
|
|
<head>
|
|
<%= htmlWebpackPlugin.tags.headTags %>
|
|
</head>
|
|
<body>
|
|
<%= htmlWebpackPlugin.tags.bodyTags %>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
- `htmlWebpackPlugin.files`: direct access to the files used during the compilation.
|
|
|
|
```typescript
|
|
publicPath: string;
|
|
js: string[];
|
|
css: string[];
|
|
manifest?: string;
|
|
favicon?: string;
|
|
```
|
|
|
|
|
|
- `webpackConfig`: the webpack configuration that was used for this compilation. This
|
|
can be used, for example, to get the `publicPath` (`webpackConfig.output.publicPath`).
|
|
|
|
- `compilation`: the webpack [compilation object](https://webpack.js.org/api/compilation-object/).
|
|
This can be used, for example, to get the contents of processed assets and inline them
|
|
directly in the page, through `compilation.assets[...].source()`
|
|
(see [the inline template example](examples/inline/template.pug)).
|
|
|
|
|
|
The template can also be directly inlined directly into the options object.
|
|
⚠️ **`templateContent` does not allow to use webpack loaders for your template and will not watch for template file changes**
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
new HtmlWebpackPlugin({
|
|
templateContent: `
|
|
<html>
|
|
<body>
|
|
<h1>Hello World</h1>
|
|
</body>
|
|
</html>
|
|
`
|
|
})
|
|
```
|
|
|
|
The `templateContent` can also access all `templateParameters` values.
|
|
⚠️ **`templateContent` does not allow to use webpack loaders for your template and will not watch for template file changes**
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
new HtmlWebpackPlugin({
|
|
inject: false,
|
|
templateContent: ({htmlWebpackPlugin}) => `
|
|
<html>
|
|
<head>
|
|
${htmlWebpackPlugin.tags.headTags}
|
|
</head>
|
|
<body>
|
|
<h1>Hello World</h1>
|
|
${htmlWebpackPlugin.tags.bodyTags}
|
|
</body>
|
|
</html>
|
|
`
|
|
})
|
|
```
|
|
|
|
### Filtering Chunks
|
|
|
|
To include only certain chunks you can limit the chunks being used
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
plugins: [
|
|
new HtmlWebpackPlugin({
|
|
chunks: ['app']
|
|
})
|
|
]
|
|
```
|
|
|
|
It is also possible to exclude certain chunks by setting the `excludeChunks` option
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
plugins: [
|
|
new HtmlWebpackPlugin({
|
|
excludeChunks: [ 'dev-helper' ]
|
|
})
|
|
]
|
|
```
|
|
|
|
### Minification
|
|
|
|
If the `minify` option is set to `true` (the default when webpack's `mode` is `'production'`),
|
|
the generated HTML will be minified using [html-minifier-terser](https://github.com/DanielRuf/html-minifier-terser)
|
|
and the following options:
|
|
|
|
```js
|
|
{
|
|
collapseWhitespace: true,
|
|
removeComments: true,
|
|
removeRedundantAttributes: true,
|
|
removeScriptTypeAttributes: true,
|
|
removeStyleLinkTypeAttributes: true,
|
|
useShortDoctype: true
|
|
}
|
|
```
|
|
|
|
To use custom [html-minifier options](https://github.com/DanielRuf/html-minifier-terser#options-quick-reference)
|
|
pass an object to `minify` instead. This object will not be merged with the defaults above.
|
|
|
|
To disable minification during production mode set the `minify` option to `false`.
|
|
|
|
### Meta Tags
|
|
|
|
If the `meta` option is set the html-webpack-plugin will inject meta tags.
|
|
For the default template the html-webpack-plugin will already provide a default for the `viewport` meta tag.
|
|
|
|
Please take a look at this well maintained list of almost all [possible meta tags](https://github.com/joshbuchea/HEAD#meta).
|
|
|
|
#### name/content meta tags
|
|
|
|
Most meta tags are configured by setting a `name` and a `content` attribute.
|
|
To add those use a key/value pair:
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
plugins: [
|
|
new HtmlWebpackPlugin({
|
|
'meta': {
|
|
'viewport': 'width=device-width, initial-scale=1, shrink-to-fit=no',
|
|
// Will generate: <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
|
|
'theme-color': '#4285f4'
|
|
// Will generate: <meta name="theme-color" content="#4285f4">
|
|
}
|
|
})
|
|
]
|
|
```
|
|
|
|
#### Simulate http response headers
|
|
|
|
The **http-equiv** attribute is essentially used to simulate a HTTP response header.
|
|
This format is supported using an object notation which allows you to add any attribute:
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
plugins: [
|
|
new HtmlWebpackPlugin({
|
|
'meta': {
|
|
'Content-Security-Policy': { 'http-equiv': 'Content-Security-Policy', 'content': 'default-src https:' },
|
|
// Will generate: <meta http-equiv="Content-Security-Policy" content="default-src https:">
|
|
// Which equals to the following http header: `Content-Security-Policy: default-src https:`
|
|
'set-cookie': { 'http-equiv': 'set-cookie', content: 'name=value; expires=date; path=url' },
|
|
// Will generate: <meta http-equiv="set-cookie" content="value; expires=date; path=url">
|
|
// Which equals to the following http header: `set-cookie: value; expires=date; path=url`
|
|
}
|
|
})
|
|
]
|
|
```
|
|
|
|
### Base Tag
|
|
|
|
When the `base` option is used,
|
|
html-webpack-plugin will inject a [base tag](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/base).
|
|
By default, a base tag will not be injected.
|
|
|
|
The following two are identical and will both insert `<base href="http://example.com/some/page.html">`:
|
|
|
|
```js
|
|
new HtmlWebpackPlugin({
|
|
'base': 'http://example.com/some/page.html'
|
|
})
|
|
```
|
|
|
|
```js
|
|
new HtmlWebpackPlugin({
|
|
'base': { 'href': 'http://example.com/some/page.html' }
|
|
})
|
|
```
|
|
|
|
The `target` can be specified with the corresponding key:
|
|
|
|
```js
|
|
new HtmlWebpackPlugin({
|
|
'base': {
|
|
'href': 'http://example.com/some/page.html',
|
|
'target': '_blank'
|
|
}
|
|
})
|
|
```
|
|
|
|
which will inject the element `<base href="http://example.com/some/page.html" target="_blank">`.
|
|
|
|
### Long Term Caching
|
|
|
|
For long term caching add `contenthash/templatehash` to the filename.
|
|
|
|
**Example:**
|
|
|
|
```js
|
|
plugins: [
|
|
new HtmlWebpackPlugin({
|
|
filename: 'index.[contenthash].html'
|
|
})
|
|
]
|
|
```
|
|
|
|
`contenthash/templatehash` is the hash of the content of the output file.
|
|
|
|
Optionally, You can configure like `[<hashType>:contenthash:<digestType>:<length>]`
|
|
|
|
* `hashType` - one of `sha1`, `md5`, `sha256`, `sha512` or any other node.js supported hash type
|
|
* `digestType` - one of `hex`, `base26`, `base32`, `base36`, `base49`, `base52`, `base58`, `base62`, `base64`
|
|
* `maxlength` - maximum length of the generated hash in chars
|
|
|
|
**Defaults:** `[md5:contenthash:hex:9999]`
|
|
|
|
### Events
|
|
|
|
To allow other [plugins](https://github.com/webpack/docs/wiki/plugins) to alter the HTML this plugin executes
|
|
[tapable](https://github.com/webpack/tapable/tree/master) hooks.
|
|
|
|
The [lib/hooks.js](https://github.com/jantimon/html-webpack-plugin/blob/master/lib/hooks.js) contains all information
|
|
about which values are passed.
|
|
|
|

**plugin.js**
|
|
```js
|
|
// If your plugin is direct dependent to the html webpack plugin:
|
|
const HtmlWebpackPlugin = require('html-webpack-plugin');
|
|
// If your plugin is using html-webpack-plugin as an optional dependency
|
|
// you can use https://github.com/tallesl/node-safe-require instead:
|
|
const HtmlWebpackPlugin = require('safe-require')('html-webpack-plugin');
|
|
|
|
class MyPlugin {
|
|
apply (compiler) {
|
|
compiler.hooks.compilation.tap('MyPlugin', (compilation) => {
|
|
console.log('The compiler is starting a new compilation...')
|
|
|
|
// Static Plugin interface |compilation |HOOK NAME | register listener
|
|
HtmlWebpackPlugin.getHooks(compilation).beforeEmit.tapAsync(
|
|
'MyPlugin', // <-- Set a meaningful name here for stacktraces
|
|
(data, cb) => {
|
|
// Manipulate the content
|
|
data.html += 'The Magic Footer'
|
|
// Tell webpack to move on
|
|
cb(null, data)
|
|
}
|
|
)
|
|
})
|
|
}
|
|
}
|
|
|
|
module.exports = MyPlugin
|
|
```
|
|
|
|
**webpack.config.js**
|
|
```js
|
|
plugins: [
|
|
new MyPlugin({ options: '' })
|
|
]
|
|
```
|
|
|
|
Note that the callback must be passed the HtmlWebpackPluginData in order to pass this onto any other plugins listening on the same `beforeEmit` event
