# BrowserContext class
|
|
|
|
BrowserContexts provide a way to operate multiple independent browser sessions. When a browser is launched, it has a single BrowserContext used by default. The method [Browser.newPage](./puppeteer.browser.newpage.md) creates a page in the default browser context.
|
|
|
|
#### Signature:
|
|
|
|
```typescript
|
|
export declare class BrowserContext extends EventEmitter<BrowserContextEvents>
|
|
```
|
|
|
|
**Extends:** [EventEmitter](./puppeteer.eventemitter.md)<[BrowserContextEvents](./puppeteer.browsercontextevents.md)>
|
|
|
|
## Remarks
|
|
|
|
The Browser class extends from Puppeteer's [EventEmitter](./puppeteer.eventemitter.md) class and will emit various events which are documented in the [BrowserContextEvents](./puppeteer.browsercontextevents.md) enum.
|
|
|
|
If a page opens another page, e.g. with a `window.open` call, the popup will belong to the parent page's browser context.
|
|
|
|
Puppeteer allows creation of "incognito" browser contexts with [Browser.createIncognitoBrowserContext](./puppeteer.browser.createincognitobrowsercontext.md) method. "Incognito" browser contexts don't write any browsing data to disk.
|
|
|
|
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
|
|
|
|
```ts
|
|
// Create a new incognito browser context
|
|
const context = await browser.createIncognitoBrowserContext();
|
|
// 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();
|
|
```
