If you want to boost the performance of your Express.js app, one option is to use a memory cache package like Node-Cache or Memory-Cache. These packages allow you to store data in memory for a set amount of time, which can be extremely useful for frequently accessed data that does not need to be constantly updated.
Example Code:
const cache = require('memory-cache');
cache.put('video_123', 'This is the description of video 123', 60 * 60 * 1000); // store for 1 hour
const description = cache.get('video_123');
Overall, using a memory cache package can significantly improve the performance of your Express.js app by reducing the number of API calls and database queries needed to retrieve data.
