[mgan59]

Context

We are looking to begin development of our Open Source API for the gitbabel platform.

The starting point is to create the Express app which we will generate inside of the api/ folder and it should contain the package.json and readme that explains how to run the API.

Actions

• Run the Express Easy Setup cli inside of the API folder
  • Ensure that the package.json has a npm run command that will run the server
  • Ensure that the .env can be used with the server
• Verify that the API will start
• stretch is create the github action that will run the build and verify it works
