The core concept of this service was to serve a gateway to all the incoming traffic. As the traffic grew the service introduced some performance spikes so I decided to distribute the traffic through the main load balancer. Now, this service is focused on user management. Registration, login, logout, referrals, and other user oriented functionality.

Local environment

Daily Gateway requires a running instance of MySQL.

Make sure to apply the latest migrations by running: yarn knex:migrate:latest

Check out the config.js file to see the environment variables list. Some of the variables have a default value preconfigured.

Finally run yarn watch to run the service and listen to port 4000.
