Teaching backend with Node.js

Notes from mentoring new developers on Express APIs and practical backend habits.

  • nodejs
  • teaching

At Cubos Academy I spend a lot of time helping people go from “I can write JavaScript” to “I can ship a small API.”

A few habits that help early on:

  1. Start with a clear resource — name the route after the thing it returns.
  2. Validate input early — bad data should fail before it hits the database.
  3. Keep handlers thin — move business logic into functions you can test.
  4. Log useful failures — status codes alone rarely explain what went wrong.

The goal is not perfection on day one. It is shipping something understandable, then iterating.
