How to handle redis connection in node.js?

@lew 

To handle a Redis connection in Node.js, you can use the popular npm package called redis. Here is a step-by-step guide on how to handle Redis connection in Node.js:

1. Install the redis npm package by running the following command: npm install redis
2. Import the redis package in your Node.js application: const redis = require('redis');
3. Create a Redis client by connecting to the Redis server: const client = redis.createClient({ host: '127.0.0.1', // Redis server host port: 6379, // Redis server port }); client.on('error', (error) => { console.error(error); }); client.on('connect', () => { console.log('Connected to Redis server'); });
4. Now you can use the client object to interact with the Redis server, such as setting and getting values: client.set('key', 'value', (error) => { if (error) { console.error(error); } }); client.get('key', (error, value) => { if (error) { console.error(error); } else { console.log('Value:', value); } });
5. Finally, remember to close the connection to the Redis server when you are done using it: client.quit((error) => { if (error) { console.error(error); } else { console.log('Disconnected from Redis server'); } });

By following these steps, you can successfully handle a Redis connection in your Node.js application.
