## Integrations

- [`universal-cookie`](https://www.npmjs.com/package/universal-cookie) - Universal cookies for JavaScript
- [`universal-cookie-express`](https://www.npmjs.com/package/universal-cookie-express) - Hook cookies get/set on Express for server-rendering

## Minimum requirement

### react-cookie @ v3.0+

- React.js >= 16.3.0 (new context API + forward ref)

### react-cookie @ v0.0-v2.2

- React.js >= 15

## Getting started

`npm install react-cookie`

or in the browser (global variable `ReactCookie`):

```html
<script
  crossorigin
  src="https://unpkg.com/react@16/umd/react.production.js"
></script>
<script
  crossorigin
  src="https://unpkg.com/universal-cookie@3/umd/universalCookie.min.js"
></script>
<script
  crossorigin
  src="https://unpkg.com/react-cookie@3/umd/reactCookie.min.js"
></script>
```

## `<CookiesProvider />`

Set the user cookies

On the server, the `cookies` props must be set using `req.universalCookies` or `new Cookie(cookieHeader)`

## `useCookies([dependencies])`

Access and modify cookies using React hooks.

```jsx
const [cookies, setCookie, removeCookie] = useCookies(['cookie-name']);
```

**React hooks are available starting from React 16.8**

### `dependencies` (optional)

Let you optionally specify a list of cookie names your component depend on or that should trigger a re-render. If unspecified, it will render on every cookie change.

### `cookies`

Javascript object with all your cookies. The key is the cookie name.

### `setCookie(name, value, [options])`

Set a cookie value

- name (string): cookie name
- value (string|object): save the value and stringify the object if needed
- options (object): Support all the cookie options from RFC 6265
  - path (string): cookie path, use `/` as the path if you want your cookie to be accessible on all pages
  - expires (Date): absolute expiration date for the cookie
  - maxAge (number): relative max age of the cookie from when the client receives it in seconds
  - domain (string): domain for the cookie (sub.domain.com or .allsubdomains.com)
  - secure (boolean): Is only accessible through HTTPS?
  - httpOnly (boolean): Can only the server access the cookie? **Note: You cannot get or set httpOnly cookies from the browser, only the server.**
  - sameSite (boolean|none|lax|strict): Strict or Lax enforcement

### `removeCookie(name, [options])`

Remove a cookie

- name (string): cookie name
- options (object): Support all the cookie options from RFC 6265
  - path (string): cookie path, use `/` as the path if you want your cookie to be accessible on all pages
  - expires (Date): absolute expiration date for the cookie
  - maxAge (number): relative max age of the cookie from when the client receives it in seconds
  - domain (string): domain for the cookie (sub.domain.com or .allsubdomains.com)
  - secure (boolean): Is only accessible through HTTPS?
  - httpOnly (boolean): Can only the server access the cookie? **Note: You cannot get or set httpOnly cookies from the browser, only the server.**
  - sameSite (boolean|none|lax|strict): Strict or Lax enforcement

## `withCookies(Component)`

Give access to your cookies anywhere. Add the following props to your component:

- cookies: Cookies instance allowing you to get, set and remove cookies.
- allCookies: All your current cookies in an object.

Your original static properties will be hoisted on the returned component. You can also access the original component by using the `WrappedComponent` static property. Example:

```jsx
function MyComponent() {
  return null;
}
const NewComponent = withCookies(MyComponent);
NewComponent.WrappedComponent === MyComponent;
```

## Cookies

### `get(name, [options])`

Get a cookie value

- name (string): cookie name
- options (object):
  - doNotParse (boolean): do not convert the cookie into an object no matter what

### `getAll([options])`

Get all cookies

- options (object):
  - doNotParse (boolean): do not convert the cookie into an object no matter what

### `set(name, value, [options])`

Set a cookie value

- name (string): cookie name
- value (string|object): save the value and stringify the object if needed
- options (object): Support all the cookie options from RFC 6265
  - path (string): cookie path, use `/` as the path if you want your cookie to be accessible on all pages
  - expires (Date): absolute expiration date for the cookie
  - maxAge (number): relative max age of the cookie from when the client receives it in seconds

  - httpOnly (boolean): Can only the server access the cookie? **Note: You cannot get or set httpOnly cookies from the browser, only the server.**
  - sameSite (boolean|none|lax|strict): Strict or Lax enforcement

## Simple Example with React hooks

```js
// Root.jsx
import React from 'react';
import App from './App';
import { CookiesProvider } from 'react-cookie';

export default function Root() {
  return (
    <CookiesProvider>
      <App />
    </CookiesProvider>
  );
}
```

```js
// App.jsx
import React from 'react';
import { useCookies } from 'react-cookie';

import NameForm from './NameForm';

function App() {
  const [cookies, setCookie] = useCookies(['name']);

  function onChange(newName) {
    setCookie('name', newName, { path: '/' });
  }

  return (
    <div>
      <NameForm name={cookies.name} onChange={onChange} />
      {cookies.name && <h1>Hello {cookies.name}!</h1>}
    </div>
  );
}

export default App;
```

## Simple Example with Higher-Order Component

```js
// Root.jsx
import React from 'react';
import App from './App';
import { CookiesProvider } from 'react-cookie';

export default function Root() {
  return (
    <CookiesProvider>
      <App />
    </CookiesProvider>
  );
}
```

```js
// App.jsx
import React, { Component } from 'react';
import { instanceOf } from 'prop-types';
import { withCookies, Cookies } from 'react-cookie';

import NameForm from './NameForm';

class App extends Component {
  static propTypes = {
    cookies: instanceOf(Cookies).isRequired
  };

  constructor(props) {
    super(props);

    const { cookies } = props;
    this.state = {
      name: cookies.get('name') || 'Ben'
    };
  }

  handleNameChange(name) {
    const { cookies } = this.props;

    cookies.set('name', name, { path: '/' });
    this.setState({ name });
  }

  render() {
    const { name } = this.state;

    return (
      <div>
        <NameForm name={name} onChange={this.handleNameChange.bind(this)} />
        {this.state.name && <h1>Hello {this.state.name}!</h1>}
      </div>
    );
  }
}

export default withCookies(App);
```

## Server-Rendering Example

```js
// src/components/App.js
import React from 'react';
import { useCookies } from 'react-cookie';

import NameForm from './NameForm';

function App() {
  const [cookies, setCookie] = useCookies(['name']);

  function onChange(newName) {
    setCookie('name', newName, { path: '/' });
  }

  return (
    <div>
      <NameForm name={cookies.name} onChange={onChange} />
      {cookies.name && <h1>Hello {cookies.name}!</h1>}
    </div>
  );
}

export default App;
```

```js
// src/server.js
import React from 'react';
import ReactDOMServer from 'react-dom/server';
import { CookiesProvider } from 'react-cookie';

import Html from './components/Html';
import App from './components/App';

export default function middleware(req, res) {
  const markup = ReactDOMServer.renderToString(
    <CookiesProvider cookies={req.universalCookies}>
      <App />
    </CookiesProvider>
  );

  const html = ReactDOMServer.renderToStaticMarkup(<Html markup={markup} />);

  res.send('<!DOCTYPE html>' + html);
}
```

```js
// src/client.js
import React from 'react';
import ReactDOM from 'react-dom';
import { CookiesProvider } from 'react-cookie';

import App from './components/App';

const appEl = document.getElementById('main-app');

ReactDOM.render(
  <CookiesProvider>
    <App />
  </CookiesProvider>,
  appEl
);
```

```js
// server.js
require('@babel/register');

const express = require('express');
const serverMiddleware = require('./src/server').default;
const cookiesMiddleware = require('universal-cookie-express');

const app = express();

app
  .use('/assets', express.static('dist'))
  .use(cookiesMiddleware())
  .use(serverMiddleware);

app.listen(8080, function() {
  console.log('Listening on 8080...');
});
```
