Worker threads in Node.js let you offload heavy CPU intensive operations to separate threads without blocking the main loop
How do worker threads work
Worker threads run in parallel to the main thread, make a new worker thread assign it a task and it’ll communicate with the main thread via a messaging system
Features of Worker Threads
Multithreading
Each thread executes code independently, enabling true multi threading
Memory Isolation
Each worker has its own memory space, reducing risk of issues related to the shared state
Concurrency
Allows Node.js to handle multiple operations simultaneously
Communication
Worker threads communicate with main thread through message passing, simple APIs like postMessage and onMessage facilitate this communication
