BrowserContext class

BrowserContext represents individual user contexts within a browser.

When a browser is launched, it has a single browser context by default. Others can be created using Browser.createBrowserContext(). Each context has isolated storage (cookies/localStorage/etc.)

BrowserContext emits various events which are documented in the BrowserContextEvent enum.

If a page opens another page, e.g. using window.open, the popup will belong to the parent page's browser context.

Signature:

export declare abstract class BrowserContext extends EventEmitter<BrowserContextEvents>

Extends: EventEmitter<BrowserContextEvents>

Remarks

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the BrowserContext class.

Example

Creating a new browser context:

// Create a new browser context
const context = await browser.createBrowserContext();
// Create a new page inside context.
const page = await context.newPage();
// ... do stuff with page ...
await page.goto('https://example.com');
// Dispose context once it's no longer needed.
await context.close();
