DevOps Lab

In this lab you will practice traceability with RollBar.

Overview

In this lab you will install Rollbar and implement it into a node application.

Step 1

• Build a node application using express and deploy it to AWS EC2 (or, open up a node application you already have deployed to AWS EC2)

• Link your Rollbar account to your repo

• Back in your code, import Rollbar and create a new instance of it using your `post_server_item access token

• Add an endpoint and in the callback function, call a function that does not exist so you can test out Rollbar (hint: try using a try…catch block)

• Push your code, redeploy (if you don’t have automatic deployments on), and go to that endpoint to trigger your error

• Check your Rollbar dashboard, you should have an error being displayed

Step 2

• Expand your error handling by creating custom Rollbar errors

• Create at least one Rollbar critical error

• Create at least one Rollbar warning

Step 3

• Continue to build out your application by adding new features

• Make sure to include Rollbar error handling in your code (front-end or back-end)

• As you are testing your app locally, go check out your Rollbar dashboard to see if you have any errors

• Each time you have added a feature to your application, push your changes and redeploy

• Once deployed, go and test those features on the deployed site, checking out your Rollbar dashboard as yo go along
