How do I implement caching in my app?

Implementing caching can significantly improve your app's performance. What type of caching are you considering: in-memory, distributed, or browser caching?

I'm thinking of in-memory caching. How can I do that?

For in-memory caching, you can use libraries like Redis or Memcached. Would you like a code example for either?

Yes, please provide a code example using Redis.

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

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

client.on('error', (err) => {
  console.log('Error ' + err);
});

// Set a value
client.set('key', 'value', redis.print);

// Get a value
client.get('key', (err, reply) => {
  console.log(reply); // Will print 'value'
});
