Use Puppeteer’s cookie methods to inspect the cookies available in a browser context, set cookies before or after navigation, and remove them during cleanup. For simple scripts, the Browser methods operate on the default context; use the equivalent BrowserContext methods when you need isolated test state. The examples below use the current documented API shape; check the API reference for your installed Puppeteer version because supported fields can vary.

Read cookies from Puppeteer

browser.cookies() returns the cookies available in Puppeteer’s default browser context. To inspect a particular context, call context.cookies() instead. Cookie access is asynchronous, so await the result.

const cookies = await browser.cookies();
console.log(cookies);

To read cookies for a specific page or URL, the guide’s browser-level method returns the cookies available in the default context. If your work uses a non-default context, use its cookie method so the result corresponds to that isolated cookie jar. See the Puppeteer cookies guide and the Browser API reference.

Set cookies for a page or test

Pass one or more cookie objects to browser.setCookie(...cookies) to set cookies in the default context. Use context.setCookie(...cookies) to target a specific context. A cookie requires a name and value; define scope and security attributes to match the application under test.

Magicmoon 2-Pack 24 Inch Computer Privacy Screen Filter for 16:9 Monitor
  • Compatible Model(s): Magicmoon brand filter only for 24 inch -diagonally measured - widescreen monitor - aspect ratio 16:9 - filter size: width: 20 15/16", Height: 11 13/16" (531mm x 298mm)
  • Superior Privacy: The computer privacy filter makes the screen appear dark when looking at it from an angle (the angle is about 30 to 60 degree), but bright when looking directly at it. To change the privacy level - simply adjust your monitor’s brightness accordingly
  • Eye and Screen Protection: Privacy Filter does not only protect your private life but also protects your eyes by blocking 30% of blue light , blocking the harmful blue light between 380 to 495 nm, it filters out the blue light and relieves eye strain
  • Perfect For Open Workspaces: Great for maintaining screen privacy in open work spaces
  • Includes Two Options: Option 1 uses clear adhesive strips that securely attach to any computer screen. Option 2 (for computer screens with a raised bezel only) uses slide mount tabs that easily stick to the display frame, allowing you to slide the privacy screen filter on and off as needed
await browser.setCookie({
  name: 'session',
  value: 'test-session-value',
  domain: 'localhost',
  path: '/',
  httpOnly: true,
  secure: false,
  sameSite: 'Lax'
});

The values in this example are for a local test only. Use the target site’s correct domain, path, HTTPS behavior, and SameSite policy rather than copying them indiscriminately. Puppeteer also documents a page-level CookieParam with an optional url, which can affect default domain, path, and source-scheme values. Consult the CookieParam reference when choosing that form.

Cookie attributes to choose deliberately

  • domain and path determine where the cookie applies. Use values consistent with the target application.
  • expires is a number; if omitted, the cookie is a session cookie.
  • httpOnly and secure are boolean attributes. Match them to how the application uses the cookie and whether the site is served over HTTPS.
  • sameSite should reflect the behavior the test is meant to exercise.
  • partitionKey is available for partitioned-cookie cases. Only include it when the test requires that scope.
  • priority and sourceScheme are documented as Chrome-supported fields; do not assume they are portable across browsers.

The documented CookieData fields and platform qualifications are listed in the CookieData reference. Verify the reference matching your installed Puppeteer release.

Delete cookies and clean up state

Use browser.deleteCookie(...cookies) to delete specified cookie objects from the default context, or call context.deleteCookie(...cookies) for a chosen context. For filter-based cleanup, BrowserContext.deleteMatchingCookies(...filters) removes matching cookies within that context.

const cookies = await browser.cookies();
await browser.deleteCookie(...cookies);

The example clears the cookies returned from the default context. For cleanup scoped by filters, check the filter shape for your Puppeteer version in the deleteMatchingCookies reference. Browser-level methods are shortcuts for the default browser context; they do not clear cookies from other contexts.

Isolate cookie state between tests

A BrowserContext isolates browser storage, including cookies and local storage. Create a separate context when a test should not share state with other contexts, open its pages through that context, and close it when finished. Closing a context closes its associated pages; the default context cannot be closed. In Chrome, Puppeteer’s current class reference describes non-default contexts as incognito.

const context = await browser.createBrowserContext();
try {
  const page = await context.newPage();
  await context.setCookie({
    name: 'session',
    value: 'isolated-test-value',
    domain: 'localhost',
    path: '/'
  });
  await page.goto('http://localhost:3000');
  console.log(await context.cookies());
} finally {
  await context.close();
}

For tests that intentionally share a logged-in state, keep the setup and cleanup within the same context. For independent tests, create and close a context per test or per isolated test group. See the BrowserContext reference.

Common problems and fixes

  • The cookie does not appear on the page: confirm the domain and path match the URL, and check whether secure or SameSite settings prevent the scenario you are testing. If using a separate context, inspect that context’s cookies rather than the default context’s.
  • Cookie changes seem to disappear: check whether you are using the intended context and whether the cookie has an expiry. An omitted expiry creates a session cookie, and closing a context closes its pages and isolated storage.
  • Setting a cookie fails or behaves differently across browsers: compare the object against the installed release’s CookieData or CookieParam documentation. Fields such as priority and sourceScheme are documented as Chrome-only.
  • Cleanup removes too much or too little: use explicit cookie objects when you know which cookies to delete, or carefully scope deleteMatchingCookies filters to the intended context.
