How can I optimize the performance of my Node.js application?
There are several strategies you can use, such as using asynchronous programming, optimizing your database queries, and implementing caching.
What are some best practices for asynchronous programming in Node.js?
Best practices include using Promises or async/await for better readability, avoiding callback hell, and handling errors properly.
Can you explain how caching can improve performance?
Caching stores frequently accessed data in memory, reducing the need to fetch it from the database, which speeds up response times.
What tools can I use to monitor my application's performance?
You can use tools like New Relic, AppDynamics, or even built-in Node.js modules like 'perf_hooks' for performance monitoring.
