Running application
To run application:
docker-compose up --build
Then:
http://localhost:8000
It could be that Mongo is not ready by the time Node is trying to connect so it will exit with code 1 but dockerd will restart it because of the restart policy in docker-compose so on the second attempt connection should be successful.
Running tests
To run tests go to app folder and run npm install and once installation of node packages is complete
run npm test.
