Caching with Aiven for Redis® and Express.js

This tutorial provides a quickstart guide for using Redis as a cache for your Node.js Express app. It demonstrates how to create two apps, one with Redis caching and another without, to show the benefits of Redis in terms of speed and efficiency. The API used is Alpha Vantage's Bitcoin health information API. The tutorial also covers setting up Redis, connecting it to your server, creating a new route for caching data, running benchmarks, and moving forward with more complex projects.
