How do I clear the cache in Express.js?

To clear the cache in Express.js, you can use the cache middleware. You can set it up to clear the cache on specific routes.

Can you show me an example of how to implement that?

Sure! You can use the memory-cache package. First, install it using npm, then use it in your route like this:

const cache = require('memory-cache');

app.get('/your-route', (req, res) => {
    const cachedData = cache.get('yourKey');
    if (cachedData) {
        return res.send(cachedData);
    }
    // Fetch data and cache it
    const data = fetchData();
    cache.put('yourKey', data, 60000); // Cache for 60 seconds
    res.send(data);
});

What if I want to clear the cache manually?

You can clear the cache manually by using cache.del('yourKey'); to remove specific entries or cache.clear(); to clear all cached data.
