How To Implement Caching in Node.js Using Redis?

I’m working on a Node.js app that needs to run faster, especially when it comes to fetching the same data over and over. I’ve read that using Redis can help by storing data in memory, making it quicker to access. But I’m not exactly sure how to get started. I need help figuring out how to install Redis, connect it to my Node.js app, and then use it to store and retrieve data. Also, I’m worried about how to keep the cached data updated so that users always see the latest information. Any simple instructions or tips on how to do this would be great.
