A Video Course Platform Built for a Course Called Modern DevTools

In this episode of Running in Production, Umar Hansa talks about building a video course platform with Express and Node. It’s hosted on a single $10 / month DigitalOcean server. It took about 3 months of part time development and has been up and running since late 2017.

Umar talks about keeping it simple, building a server rendered monolith, using SQLite and not being afraid to build something from scratch. He covered a lot of ground in this episode.

Support the Show

This episode does not have a sponsor and this podcast is a labor of love. If you want to support the show, the best way to do it is to purchase one of my courses or suggest one to a friend.

  • Dive into Docker is a video course that takes you from not knowing what Docker is to being able to confidently use Docker and Docker Compose for your own apps. Long gone are the days of "but it works on my machine!". A bunch of follow along labs are included.
  • Build a SAAS App with Flask is a video course where we build a real world SAAS app that accepts payments, has a custom admin, includes high test coverage and goes over how to implement and apply 50+ common web app features. There's over 20+ hours of video.
