• MONGO_URL URL to a running Mongo instance which includes user and password
• BYPASS_MONGO if set to "true", will drop the database on each request, to get fresh data from external APIS. Use with caution.

Watches for changes to TypeScript files and compiles them to JavaScript (use yarn run build to do it manually)

Runs the development server and restarts it when any file is changed

Runs the cron job feature using ts-node

Runs the server

Runs the test suite

Starts the API and cron job in production mode. TypeScript files are compiled in memory on application start.

To view the production logs:

1. Run sudo sh -c "du -ch /var/lib/docker/containers/*/*-json.log" to print the list of logs. Look for the biggest one and copy the container ID.
2. Run docker logs -f --tail 100 CONTAINER_ID

If the production server is unstable, it could be because the Docker cache is filling the hard drive. To fix it, run docker system prune -a to clear unused stuff.
