# BrowserFetcher class

BrowserFetcher can download and manage different versions of Chromium and Firefox.

#### Signature:

```typescript
export declare class BrowserFetcher
```

## Remarks

BrowserFetcher is not designed to work concurrently with other instances of BrowserFetcher that share the same downloads directory.

## Example

An example of using BrowserFetcher to download a specific version of Chromium and running Puppeteer against it:

```ts
const browserFetcher = new BrowserFetcher({path: 'path/to/download/folder'});
const revisionInfo = await browserFetcher.download('533271');
const browser = await puppeteer.launch({
  executablePath: revisionInfo.executablePath,
});
```
