Class: Cookies

Query and modify a session's cookies.

Process: Main

Instances of the Cookies class are accessed by using cookies property of a Session.

For example:

const { session } = require('electron')

// Query all cookies.
session.defaultSession.cookies.get({})
  .then((cookies) => {
    console.log(cookies)
  }).catch((error) => {
    console.log(error)
  })

// Query all cookies associated with a specific url.
session.defaultSession.cookies.get({ url: 'http://www.github.com' })
  .then((cookies) => {
    console.log(cookies)
  }).catch((error) => {
    console.log(error)
  })

// Set a cookie with the given cookie data;
// may overwrite equivalent cookies if they exist.
const cookie = { url: 'http://www.github.com', name: 'dummy_name', value: 'dummy' }
session.defaultSession.cookies.set(cookie)
  .then(() => {
    // success
  }, (error) => {
    console.error(error)
  })

Instance Events

The following events are available on instances of Cookies:

Event: 'changed'

  • event Event
  • cookie Cookie - The cookie that was changed.
  • cause String - The cause of the change with one of the following values:
    • explicit - The cookie was changed directly by a consumer's action.
    • overwrite - The cookie was automatically removed due to an insert operation that overwrote it.
    • expired - The cookie was automatically removed as it expired.
    • evicted - The cookie was automatically evicted during garbage collection.
    • expired-overwrite - The cookie was overwritten with an already-expired expiration date.
  • removed Boolean - true if the cookie was removed, false otherwise.

Emitted when a cookie is changed because it was added, edited, removed, or expired.

Instance Methods

The following methods are available on instances of Cookies:

cookies.get(filter)

  • filter Object
    • url String (optional) - Retrieves cookies which are associated with url. Empty implies retrieving cookies of all URLs.
    • name String (optional) - Filters cookies by name.
    • domain String (optional) - Retrieves cookies whose domains match or are subdomains of domains.
    • path String (optional) - Retrieves cookies whose path matches path.
    • secure Boolean (optional) - Filters cookies by their Secure property.
    • session Boolean (optional) - Filters out session or persistent cookies.

Returns Promise<Cookie[]> - A promise which resolves an array of cookie objects.

Sends a request to get all cookies matching filter, and resolves a promise with the response.

cookies.set(details)

  • details Object
    • url String - The URL to associate the cookie with. The promise will be rejected if the URL is invalid.
    • name String (optional) - The name of the cookie. Empty by default if omitted.
    • value String (optional) - The value of the cookie. Empty by default if omitted.
