How Can You Optimize Node.js Performance For Long-running Processes? - JavaScript Toolkit

Описание: How Can You Optimize Node.js Performance For Long-running Processes? Are you looking to improve the performance of your Node.js applications, especially for long-running processes? In this detailed video, we’ll walk you through essential strategies to keep your server responsive and efficient over time. You’ll learn how to utilize profiling and monitoring tools like Node.js built-in profilers and Clinic.js to identify bottlenecks such as CPU usage and memory leaks. We’ll also cover the importance of asynchronous operations, demonstrating how to properly implement async functions and avoid blocking the event loop with heavy tasks, ensuring your server remains responsive even under load. Managing memory effectively is another key aspect, and we’ll show you how to monitor memory consumption using process.memoryUsage() and optimize data handling with streams to process large datasets in manageable chunks. Additionally, we’ll explore load balancing techniques, including clustering and using tools like PM2 to distribute traffic across multiple server instances and CPU cores. Improving database query performance through indexing, caching, and efficient query writing is also discussed, along with strategies like pagination and filtering to handle large data volumes. Caching frequently accessed data in Redis or in-memory caches can significantly reduce data retrieval times. By combining these approaches, you can make your Node.js long processes faster, more reliable, and better prepared for growth. Keep watching, stay optimized, and ensure your server runs smoothly at all times.
