# Browser Log Collection

Send logs to Datadog from web browser pages with the browser logs SDK.

See the [dedicated datadog documentation][1] for more details.

## Usage

After adding [`@datadog/browser-logs`][2] to your `package.json` file, initialize it with:

```javascript
import { datadogLogs } from '@datadog/browser-logs'

datadogLogs.init({
  clientToken: '<DATADOG_CLIENT_TOKEN>',
  site: '<DATADOG_SITE>',
  forwardErrorsToLogs: true,
  sessionSampleRate: 100,
})
```

After the Datadog browser logs SDK is initialized, send custom log entries directly to Datadog:

```javascript
import { datadogLogs } from '@datadog/browser-logs'

datadogLogs.logger.info('Button clicked', { name: 'buttonName', id: 123 })

try {
  ...
  throw new Error('Wrong behavior')
  ...
} catch (ex) {
  datadogLogs.logger.error('Error occurred', { team: 'myTeam' }, ex)
}
```
