HTTPS Everywhere

Part of the Full Stack Developer Roadmap

In short

Serving both your frontend and backend exclusively over HTTPS in production — mixed content (an HTTPS page calling an HTTP API) is blocked by browsers and a common full-stack deployment mistake.

How to learn this

  1. 1Confirm both your deployed frontend and backend serve HTTPS with valid certificates.
  2. 2Check your frontend's API base URL uses `https://`, not `http://`, in production.
  3. 3Understand why browsers block 'mixed content' requests from an HTTPS page to an HTTP endpoint.
