Create React App

Docker Compose might have been a bit of overkill for a dev environment as a solo founder, but I'd found so much with past side projects (though this is no longer a side project) that I would frequently waste time every time I came back to work on the project getting my dev env sorted again.

Made the conscious choice to make a "prod-ish" docker-compose config up front to make sure that didn't bite me again.

Structured it so I have the following containers running

  • server - the Rails app in API style
  • client - the Create React App
  • ngrok - ngrok to receive webhooks in dev
  • db - PostgreSQL
  • queues - delayed_job worker
