# Using Rollbar with [Webpack](http://webpack.github.io/)

1. Require and initialize the Rollbar javascript module:

```js

// Download https://raw.githubusercontent.com/rollbar/rollbar.js/master/dist/rollbar.umd.nojson.min.js and place in current directory
var rollbarConfig = {
  accessToken: 'POST_CLIENT_ACCESS_TOKEN',
  captureUncaught: true,
  payload: {
    environment: 'development',
  }
};

var Rollbar = require('./rollbar.umd.nojson.min.js').init(rollbarConfig);
```

2. Report exceptions and messages in your code:

```js
try {
  foo();
  Rollbar.debug('foo() called');
} catch (e) {
  Rollbar.error('Problem calling foo()', e);
}
```

## To build and test the example
1. Edit index.js and add your Rollbar `POST_CLIENT_ACCESS_TOKEN`
