Setup Airbrake for your JavaScript application

### **Installation**

Add the library

```sh
npm install @airbrake/browser
```

### **Configuration**

```js
import { Notifier } from '@airbrake/browser';

const airbrake = new Notifier({
projectId: 386514,
projectKey: '8ced26a92117c8ac2efb12653324cbeb',
environment: 'production'
});
```

To test that Airbrake has been installed correctly in your project, start up
your JS project locally. Then visit it in your browser (eg:
`http://localhost:1080`), open the JS console, and paste in the following to
trigger a test error:

```js
window.onerror("TestError: This is a test", "path/to/file.js", 123);
```

This should send a test error to your Airbrake project.
