How can I implement caching in my application?

To implement caching, you can use in-memory stores like Redis or Memcached. What type of application are you working on?

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

Great! You can use libraries like node-cache for simple caching or integrate Redis for more complex scenarios. Do you need help with code examples?

Yes, please provide a code example for using Redis.

Sure! First, install the Redis client with npm install redis. Then, you can use the following code snippet to set and get cached data.

Thanks! How do I handle cache expiration?

You can set an expiration time when you store data in Redis using the EX option. For example, client.set('key', 'value', 'EX', 3600) sets the key to expire in one hour.
