Redis for Caching

Part of the Backend Developer Roadmap

In short

Using Redis's speed and TTL (time-to-live) support to cache database query results, computed values, or API responses — the most common caching backend for Node.js apps.

How to learn this

  1. 1Cache a slow database query's result in Redis with a sensible TTL.
  2. 2Measure the latency difference between hitting the cache vs the database.
  3. 3Learn cache key naming conventions to avoid collisions across different data types.
