Is your Node.js API slow? Do you find yourself fetching the same data from your database over and over again?
Today, I'm going to show you one of the most effective ways to fix that. We're going to speed up our API by adding a Redis cache.
Here's the plan:
First, we'll build a simple API endpoint that slowly fetches user's profile data from a database.
2- Then, we'll implement Redis to save, or 'cache,' that user's JSON object.
3- Then, we'll see how the next request for that same user is incredibly fast because it reads from the cache, not the database.
4- Finally, i will show you the cache invalidation technique to make sure the cache data always synced with database
