Caching Data to Speed Up Your Node.js and React Applications

Let’s face it — nobody likes waiting. Whether it’s for a webpage to load or for an app to respond, slow experiences can be frustrating. That’s why optimizing your app’s performance is crucial, especially when it comes to handling frequent database queries or repetitive requests. One way to make things run much smoother is by using caching. In this article, I’m going to show you how you can use caching in both Node.js and React to give your users a faster, more efficient experience.

What Exactly Is Caching?

Think of caching like this: You know how you memorize the location of your favorite snack in the kitchen? Instead of searching the entire house every time you’re hungry, you go straight to the cupboard. That’s essentially what caching does in web development.

When you cache data, you’re storing a copy of it temporarily in a quick-access spot, so the app doesn’t have to do all the heavy lifting of fetching it from the database again and again. It’s faster, easier, and reduces the strain on your backend.

Why Should You Care About Caching?

Before we jump into code, let’s talk about why caching matters. Here are a few reasons why you should start using caching today:
