How can I implement caching in my Express app?

You can use middleware like apicache or node-cache to implement caching in your Express app.

What are the benefits of caching?

Caching can significantly improve your app's performance by reducing response times and server load.

Can you show me a code example?

Sure! Here's a simple example using apicache:

const express = require('express');
const apicache = require('apicache');

const app = express();
const cache = apicache.middleware;

app.get('/data', cache('5 minutes'), (req, res) => {
  res.json({ message: 'This is cached data!' });
});

app.listen(3000, () => {
  console.log('Server running on port 3000');
});
