I uploaded sample code I'm very proud of. I had to take it out of a larger personal project called "rlty.app" and make a few changes.

What this code does :

This code is part of a larger system and performs the following functions:

It creates a service and API endpoint called "project(s)". Launches a CloudFormation stack that:

• Creates a new project bucket in S3
• Creates a new Route53 CNAME record and gives it an S3 bucket alias.

Why this code makes me happy:

There are 2 important bits here that I would like to highlight :

tests/integration
https://github.com/mbejda/code-sample/tree/master/services/projects/tests/integration

tests/unit
https://github.com/mbejda/code-sample/tree/master/services/projects/tests/unit

As I mentioned earlier, this code is part of a larger system which is made out of many moving parts. Integration tests and unit tests ensure progress can be made on a service level without creating a need to test the whole system.

Unit tests test how well the code works while integration tests test how well the code integrates with other services/parts.

Both save me a lot of time debugging , testing and developing, allowing me to spend more time on other things. That is why this code makes me happy.
