How do I implement web caching in my application?

To implement web caching, you can use techniques like HTTP caching, reverse proxies, or in-memory caches. What type of application are you working on?

I'm building a web application using Node.js.

Great! For a Node.js application, you can use libraries like node-cache or integrate with Redis for caching. Would you like a code example?

Yes, please provide a code example using Redis.

Sure! Here's a simple example using the redis package in Node.js to cache API responses:

const redis = require('redis');
const client = redis.createClient();

app.get('/api/data', (req, res) => {
    client.get('data', (err, result) => {
        if (result) {
            return res.json(JSON.parse(result));
        }
        // Fetch data from the database
        const data = fetchDataFromDatabase();
        client.setex('data', 3600, JSON.stringify(data)); // Cache for 1 hour
        res.json(data);
    });
});

This caches the API response for one hour. Let me know if you need more help!
