How do I install Node Cache?

How do I install Node Cache in my Node.js project?

To install Node Cache, you can use npm. Run the command: npm install node-cache in your project directory.

What do I need to do after installing it?

After installation, you need to require it in your code: const NodeCache = require('node-cache'); Then, you can create a cache instance.

Can you show me a simple example of how to use it?

Sure! Here's a basic example:

const NodeCache = require('node-cache');
const myCache = new NodeCache();

myCache.set('key', 'value', 10000); // Set a key with a 10 seconds TTL
const value = myCache.get('key');
console.log(value); // Outputs: 'value'

What happens if the key expires?

If the key expires, calling myCache.get('key') will return undefined.
