Sessions vs Tokens

Part of the Full Stack Developer Roadmap

In short

The two dominant approaches to remembering a logged-in user — server-side sessions (stateful, stored in a DB/Redis) vs tokens like JWT (stateless, verified without a lookup) — each with different trade-offs for a full-stack app.

How to learn this

  1. 1Implement a simple session-based login, then a token-based one, and compare the code.
  2. 2Learn why token-based auth is often preferred for APIs consumed by separate frontend apps.
  3. 3Understand sessions need shared storage (Redis) once you run multiple backend instances.
