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):

## API
```js
var cookie = require('cookie');
const cookie = require("cookie");
// import * as cookie from 'cookie';
```
### cookie.parse(str, options)
### cookie.parseCookie(str, options)
Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
Parse an HTTP `Cookie` header string and return an [object](#cookie-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');
const cookieObject = cookie.parseCookie("foo=bar; equation=E%3Dmc%5E2");
// { foo: 'bar', equation: 'E=mc^2' }
```
#### Options
`cookie.parse` accepts these properties in the options object.
- `decode` Specifies the function to decode a [cookie-value](https://datatracker.ietf.org/doc/html/rfc6265#section-4.1.1). Defaults to [`decodeURIComponent`](#encode-and-decode).
##### decode
### cookie.stringifyCookie(cookieObj, options)
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.
Stringifies a [cookie object](#cookie-object) into an HTTP `Cookie` header.
```js
var setCookie = cookie.serialize('foo', 'bar');
const cookieHeader = cookie.stringify({ a: "foo", b: "bar" });
// a=foo; b=bar
```
#### Options
- `encode` Specifies the function to encode a [cookie-value](https://datatracker.ietf.org/doc/html/rfc6265#section-4.1.1). Defaults to [`encodeURIComponent`](#encode-and-decode).
### cookie.parseSetCookie(str, options)
Parse an HTTP `Set-Cookie` header string and return an [object](#set-cookie-object) of the options.
```js
const setCookieObject = cookie.parseSetCookie("foo=bar; httpOnly");
// { name: "foo", value: "bar", httpOnly: true }
```
**Note:** Cookie follows the specification and ignores invalid attributes, but does not attempt to normalize or modify any attributes as a browser might. For example:
```js
cookie.parseSetCookie(
"session=abc; max-age=1.5; expires=invalid; custom=value; domain=example.com",
);
// { name: "session", value: "abc", domain: "example.com" }
```
#### Options
- `decode` Specifies the function to decode a [cookie-value](https://datatracker.ietf.org/doc/html/rfc6265#section-4.1.1). Defaults to [`decodeURIComponent`](#encode-and-decode).
### cookie.stringifySetCookie(setCookieObj, options)
Stringifies a [`Set-Cookie` object](#set-cookie-object) into a `Set-Cookie` header string.
```js
const setCookieHeader = cookie.stringifySetCookie({
name: "foo",
value: "bar",
});
// foo=bar
```
#### Options
`cookie.serialize` accepts these properties in the options object.
- `encode` Specifies the function to encode a [cookie-value](https://datatracker.ietf.org/doc/html/rfc6265#section-4.1.1). Defaults to [`encodeURIComponent`](#encode-and-decode).
##### domain
## Cookie object
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.
The cookie object represents all cookie name-value pairs in a `Cookie` header, where `{ name: "value" }` is used for `name=value`.
##### encode
## `Set-Cookie` object
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 `Set-Cookie` object represents all the options in a `Set-Cookie` header.
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.
### name
##### expires
The name of the cookie.
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.
### value
**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
The value of a cookie after it has been [decoded](#encode-and-decode).
### maxAge
Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute](https://tools.ietf.org/html/rfc6265#section-5.2.2).
The [cookie storage model specification](https://tools.ietf.org/html/rfc6265#section-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
### expires
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.
Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute](https://tools.ietf.org/html/rfc6265#section-5.2.1).
When no expiration is set, clients consider this a "non-persistent cookie" and delete it when the current session is over.
**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
The [cookie storage model specification](https://tools.ietf.org/html/rfc6265#section-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.
##### partitioned
### domain
Specifies the `boolean` value for the [`Partitioned` `Set-Cookie`](rfc-cutler-httpbis-partitioned-cookies)
attribute. When truthy, the `Partitioned` attribute is set, otherwise it is not. By default, the
`Partitioned` attribute is not set.
Specifies the value for the [`Domain` `Set-Cookie` attribute](https://tools.ietf.org/html/rfc6265#section-5.2.3).
When no domain is set, clients consider the cookie to apply to the current domain only.
**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.
### path
More information about can be found in [the proposal](https://github.com/privacycg/CHIPS).
Specifies the value for the [`Path` `Set-Cookie` attribute](https://tools.ietf.org/html/rfc6265#section-5.2.4).
When no path is set, the path is considered the ["default path"](https://tools.ietf.org/html/rfc6265#section-5.1.4).
##### path
### httpOnly
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].
Enables the [`HttpOnly` `Set-Cookie` attribute](https://tools.ietf.org/html/rfc6265#section-5.2.6).
When enabled, clients will not allow client-side JavaScript to see the cookie in `document.cookie`.
##### priority
### secure
Specifies the `string` to be the value for the [`Priority` `Set-Cookie` attribute][rfc-west-cookie-priority-00-4.1].
Enables the [`Secure` `Set-Cookie` attribute](https://tools.ietf.org/html/rfc6265#section-5.2.5).
When enabled, clients will only send the cookie back if the browser has an HTTPS connection.
- `'low'` will set the `Priority` attribute to `Low`.
- `'medium'` will set the `Priority` attribute to `Medium`, the default priority when not set.
- `'high'` will set the `Priority` attribute to `High`.
### partitioned
More information about the different priority levels can be found in
[the specification][rfc-west-cookie-priority-00-4.1].
Enables the [`Partitioned` `Set-Cookie` attribute](https://tools.ietf.org/html/draft-cutler-httpbis-partitioned-cookies/).
When enabled, clients will only send the cookie back when the current domain _and_ top-level domain matches.
**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.

##### sameSite
### priority
Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-09-5.4.7].
Specifies the value for the [`Priority` `Set-Cookie` attribute](https://tools.ietf.org/html/draft-west-cookie-priority-00#section-4.1).
- `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.
- `'low'` will set the `Priority` attribute to `Low`.
- `'medium'` will set the `Priority` attribute to `Medium`, the default priority when not set.
- `'high'` will set the `Priority` attribute to `High`.

## Encode and decode
Cookie accepts `encode` or `decode` options for processing a [cookie-value](https://datatracker.ietf.org/doc/html/rfc6265#section-4.1.1).
Since the value of a cookie has a limited character set (and must be a simple string), these functions are used to transform values into strings suitable for a cookies value.
The default `encode` function is the global `encodeURIComponent`.
The default `decode` function is the global `decodeURIComponent`, wrapped in a `try..catch`. If an error
is thrown it will return the cookie's original value. If you provide your own encode/decode
scheme you must ensure errors are appropriately handled.
