Installation

To use the React rollbar.js SDK, simply copy-paste the following code into the <head> of any page you'd like to monitor. Add it before all other <script> tags to ensure that errors in those scripts are reported to Rollbar.

<script>
var _rollbarConfig = {
    accessToken: "{{ client_access_token }}",
    captureUncaught: true,
    payload: {
        environment: "test"
    }
};
