Setup Airbrake for your JavaScript application

### Install Airbrake in 2 easy steps:

**Step 1:** Add the library
Include via CDN:
```html

```
We also support installation via [npm](https://github.com/airbrake/airbrake-js#installation) and [Bower](https://github.com/airbrake/airbrake-js#installation).

**Step 2:** Copy this config snippet to your `app.js` file

(You can find your project ID and API KEY with your [project's settings](https://airbrake.io/projects/171845/edit)):

```js
var airbrake = new airbrakeJs.Client({
projectId: ,
projectKey: ''
});
airbrake.addFilter(function (notice) {
notice.context.environment = 'production';
return notice;
});
```

To test that Airbrake has been installed correctly in your JavaScript project, just open up the JavaScript console in your internet browser and paste in:

```js
airbrake.notify('hey there!')
```

Visit [official GitHub repo](https://github.com/airbrake/airbrake-js) for more info on alternative configurations and advanced options.

Start by checking the application’s app.js entry point and the linked airbrake-js installation documentation. Verify how the CDN, npm, or Bower setup fits this project, then use the browser console notification example to confirm that Airbrake reports successfully.
