NodeJs — Caching with Redis

Caching improves performance by storing frequently accessed data in memory. Redis is a popular in-memory data store that integrates seamlessly with Node.js, reducing database calls and speeding up responses.

npm install redis

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

client.on('connect', () => console.log('Connected to Redis'));

client.set('key', 'value', redis.print);
client.get('key', (err, reply) => {
  console.log(reply);
});
