- Monitoring crucial metrics such as memory usage and event loop utilization is essential for preventing performance issues in Node.js applications.
Deep dives
Avoid Blocking the Event Loop
To maintain optimal performance in Node.js, it's crucial to avoid blocking the event loop. When a JavaScript function executes, it monopolizes the event loop, preventing other operations from running until completion. Developers are encouraged to break tasks into smaller chunks or offload longer tasks to worker threads. This practice not only keeps the application responsive but also enhances overall system efficiency by allowing the event loop to process I/O requests concurrently.
