More about environmental variables

After setting up your .env from the template provided in the env/.env.sample file; to use these environment variables anywhere in the app, simply:

process.env.MY_ENV_VARIABLE

Run the Service Using Docker

NOTE: Make sure no service is running on port 5000 and ensure there is a .env file with all the necessary environment variables.

To run the application just type: make start

this would run your application inside a container which you can easily access using localhost:5000.

To stop the application, you can just hit ^c.

To delete the containers: make stop

WARNING: Running below command will make you loose all your data including data in the database!

To cleanup all the containers + volumes: make clean

NOTE: The below commands should be run when the application is running inside container

To migrate database: make migrate

To seed database: make seed

To rollback migrations: make rollback

To get inside the container: make ssh

HINT: To use docker, ensure that your .env file does not contain DATABASE_URL as it conflicts with the value in docker-compose.yml

Testing

Jest is used as the testing framework for both the unit tests and integration tests. To execute all tests, run the command

  yarn test or make test
