How do I enable caching in Express?

You can enable caching in Express by using middleware like apicache or express-cache-controller. Would you like to see an example?

Yes, please provide an example using apicache.

First, install apicache using npm: npm install apicache. Then, you can use it like this:

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

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');
});

What if I want to cache different routes with different durations?

You can specify different cache durations for each route by passing a different duration string to the cache middleware. For example:

app.get('/short-cache', cache('1 minute'), (req, res) => { /* ... */ });
app.get('/long-cache', cache('10 minutes'), (req, res) => { /* ... */ });
