Like the actual John O'Shea of former Manchester United glory, this app does nothing.
It is mainly to serve as a simple Hello World / Echo app as a sample, for our infrastructure tool to deploy with.
Note: none of us are Manchester United haters. I just happen to want to use a utility player's name for this app.
Exactly.
Kidding.
The steps in the Dockerfile should provide a good idea how to run the app.
For dependency management, we use Yarn.
