Setup Rollbar

[rmariuzzo]

1. Edit src/client/index.html.
2. Add the following code (after the “Single Page Apps for GitHub Page” script)

   <script>
   var _rollbarConfig = {
   accessToken: "b6d98a1b975a4ac6adbcf22e12c69435",
   captureUncaught: true,
   captureUnhandledRejections: true,
   payload: {
       environment: "production"
   }
   };
   // Rollbar Snippet
   !function(r){function e(n){if(o[n])return o[n].exports;var t=o[n]={exports:{},id:n,loaded:!1};return r[n].call(t.exports,t,t.exports,e),t.loaded=!0,t.exports}var o={};return

   // End Rollbar Snippet
   </script>

3. Modify config/webpack.config.js to inject HTML template variable with the current NODE_ENV VALUE. For example: env: process.NODE_ENV.
4. Replace the value of the Rollbar script: environment: "production" with environment: <%= htmlWebpackPlugin.options.env %>.

@rmariuzzo I would like to try this!
