How do I implement Redis in my web application?

To implement Redis, start by installing the Redis server and the appropriate client library for your programming language.

What are the benefits of using Redis?

Redis offers high performance, scalability, and support for various data structures, making it ideal for caching and real-time analytics.

Can you show me a basic code example?

Sure! Here's a simple example in Node.js:

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

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

How do I handle errors when connecting to Redis?

You can handle errors by listening to the 'error' event on the Redis client:

client.on('error', (err) => {
  console.error('Redis error:', err);
});
