Node.js traditionally runs in a single-threaded environment, making it excellent for handling I/O-bound tasks but challenging for CPU-intensive computations. The introduction of worker_threads, stabilized in Node.js v12, allows developers to execute JavaScript code in parallel, facilitating multithreading and improving performance for heavy operations. The guide covers how to effectively implement worker threads, the communication between them, performance considerations, and how to leverage tools like N|Solid for monitoring and optimizing distributed workloads. It provides insights for building more efficient and robust applications capable of handling complex tasks.
Node.js is known for its non-blocking, event-driven architecture, great for I/O-bound tasks, but CPU-intensive operations can block the event loop, degrading performance.
Worker Threads, stabilized in Node.js v12, allow parallel processing off the main thread, enabling true multithreading in Node.js for handling asynchronous and computational workloads.
N|Solid provides real-time performance monitoring, advanced profiling, and insights into worker threads, helping to find bottlenecks and optimize Node.js applications confidently.
The article guides you through worker threads' functionality, optimal usage scenarios, implementation strategies, communication methods between threads, performance considerations, and avoiding common pitfalls.
