# BrowserContext class
|
||
|
|
||
|
[BrowserContext](./puppeteer.browsercontext.md) represents individual sessions within a [browser](./puppeteer.browser.md).
|
||
|
|
||
|
When a [browser](./puppeteer.browser.md) is launched, it has a single [browser context](./puppeteer.browsercontext.md) by default. Others can be created using [Browser.createIncognitoBrowserContext()](./puppeteer.browser.createincognitobrowsercontext.md).
|
||
|
|
||
|
[BrowserContext](./puppeteer.browsercontext.md) [emits](./puppeteer.eventemitter.md) various events which are documented in the [BrowserContextEvent](./puppeteer.browsercontextevent.md) enum.
|
||
|
|
||
|
If a [page](./puppeteer.page.md) opens another [page](./puppeteer.page.md), e.g. using `window.open`, the popup will belong to the parent [page's browser context](./puppeteer.page.browsercontext.md).
|
||
|
|
||
|
#### Signature:
|
||
|
|
||
|
```typescript
|
||
|
export declare abstract class BrowserContext extends EventEmitter<BrowserContextEvents>
|
||
|
```
|
||
|
|
||
|
**Extends:** [EventEmitter](./puppeteer.eventemitter.md)<[BrowserContextEvents](./puppeteer.browsercontextevents.md)>
|
||
|
|
||
|
## 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 an incognito [browser context](./puppeteer.browsercontext.md):
|
||
|
|
||
|
```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();
|
||
|
```
|
