|
||||
Basic HTTP cookie parser and serializer for HTTP servers.
|
||||
|
||||
## Installation
|
||||
|
||||
This is a [Node.js](https://nodejs.org/en/) module available through the
|
||||
[npm registry](https://www.npmjs.com/). Installation is done using the
|
||||
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
|
||||
|
||||
```sh
|
||||
$ npm install cookie
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
```js
|
||||
var cookie = require('cookie');
|
||||
```
|
||||
|
||||
### cookie.parse(str, options)
|
||||
|
||||
Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
|
||||
The `str` argument is the string representing a `Cookie` header value and `options` is an
|
||||
optional object containing additional parsing options.
|
||||
|
||||
```js
|
||||
var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
|
||||
// { foo: 'bar', equation: 'E=mc^2' }
|
||||
```
|
||||
|
||||
#### Options
|
||||
|
||||
`cookie.parse` accepts these properties in the options object.
|
||||
|
||||
##### decode
|
||||
|
||||
Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
|
||||
has a limited character set (and must be a simple string), this function can be used to decode
|
||||
a previously-encoded cookie value into a JavaScript string or other object.
|
||||
|
||||
The default function is the global `decodeURIComponent`, which will decode any URL-encoded
|
||||
sequences into their byte representations.
|
||||
|
||||
**note** if an error is thrown from this function, the original, non-decoded cookie value will
|
||||
be returned as the cookie's value.
|
||||
|
||||
### cookie.serialize(name, value, options)
|
||||
|
||||
Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
|
||||
name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
|
||||
argument is an optional object containing additional serialization options.
|
||||
|
||||
```js
|
||||
var setCookie = cookie.serialize('foo', 'bar');
|
||||
// foo=bar
|
||||
```
|
||||
|
||||
#### Options
|
||||
|
||||
`cookie.serialize` accepts these properties in the options object.
|
||||
|
||||
##### domain
|
||||
|
||||
Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no
|
||||
domain is set, and most clients will consider the cookie to apply to only the current domain.
|
||||
|
||||
##### encode
|
||||
|
||||
Specifies a function that will be used to encode a cookie's value. Since value of a cookie
|
||||
has a limited character set (and must be a simple string), this function can be used to encode
|
||||
a value into a string suited for a cookie's value.
|
||||
|
||||
The default function is the global `encodeURIComponent`, which will encode a JavaScript string
|
||||
into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
|
||||
|
||||
##### expires
|
||||
|
||||
Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1].
|
||||
By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
|
||||
will delete it on a condition like exiting a web browser application.
|
||||
|
||||
**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
|
||||
`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
|
||||
so if both are set, they should point to the same date and time.
|
||||
|
||||
##### httpOnly
|
||||
|
||||
Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy,
|
||||
the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
|
||||
|
||||
**note** be careful when setting this to `true`, as compliant clients will not allow client-side
|
||||
JavaScript to see the cookie in `document.cookie`.
|
||||
|
||||
##### maxAge
|
||||
|
||||
Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2].
|
||||
The given number will be converted to an integer by rounding down. By default, no maximum age is set.
|
||||
|
||||
**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
|
||||
`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
|
||||
so if both are set, they should point to the same date and time.
|
||||
|
||||
##### path
|
||||
|
||||
Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path
|
||||
is considered the ["default path"][rfc-6265-5.1.4].
|
||||
|
||||
##### sameSite
|
||||
|
||||
Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-03-4.1.2.7].
|
||||
|
||||
- `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
|
||||
- `false` will not set the `SameSite` attribute.
|
||||
- `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
|
||||
- `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie.
|
||||
- `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
|
||||
|
||||
More information about the different enforcement levels can be found in
|
||||
[the specification][rfc-6265bis-03-4.1.2.7].
|
||||
|
||||
**note** This is an attribute that has not yet been fully standardized, and may change in the future.
|
||||
This also means many clients may ignore this attribute until they understand it.
|
||||
|
||||
##### secure
|
||||
|
||||
Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy,
|
||||
the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
|
||||
|
||||
**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
|
||||
the server in the future if the browser does not have an HTTPS connection.
|
||||
|
||||
## Example
|
||||
|
||||
The following example uses this module in conjunction with the Node.js core HTTP server
|
||||
to prompt a user for their name and display it back on future visits.
|
||||
|
||||
```js
|
||||
var cookie = require('cookie');
|
||||
var escapeHtml = require('escape-html');
|
||||
var http = require('http');
|
||||
var url = require('url');
|
||||
|
||||
function onRequest(req, res) {
|
||||
// Parse the query string
|
||||
var query = url.parse(req.url, true, true).query;
|
||||
|
||||
if (query && query.name) {
|
||||
// Set a new cookie with the name
|
||||
res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
|
||||
httpOnly: true,
|
||||
maxAge: 60 * 60 * 24 * 7 // 1 week
|
||||
}));
|
||||
|
||||
// Redirect back after setting cookie
|
||||
res.statusCode = 302;
|
||||
res.setHeader('Location', req.headers.referer || '/');
|
||||
res.end();
|
||||
return;
|
||||
}
|
||||
|
||||
// Parse the cookies on the request
|
||||
var cookies = cookie.parse(req.headers.cookie || '');
|
||||
|
||||
// Get the visitor name set in the cookie
|
||||
var name = cookies.name;
|
||||
|
||||
res.setHeader('Content-Type', 'text/html; charset=UTF-8');
|
||||
|
||||
if (name) {
|
||||
res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>');
|
||||
} else {
|
||||
res.write('<p>Hello, new visitor!</p>');
|
||||
}
|
||||
|
||||
res.write('<form method="GET">');
|
||||
res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">');
|
||||
res.end('</form>');
|
||||
}
|
||||
|
||||
http.createServer(onRequest).listen(3000);

||||
