Usage

Login on /login or register with /register then use the auth_token value as a authorization header with subsequent API calls.

Web socket subscribes to POST: http://localhost:4000/ws/chat

Check config/test.exs for Test ENV config. To run test, run;

What I could have done better

Given more time, I would have;

• Added more test coverage
• Added CI deployment script
• Figure out adding route scope macro for plug routes
• Check deeply into cowboy web sockets
