nodejs 包 workerpool 和 worker_threads 有什么区别？

Question

Am new to JavaScript/NodeJs. I tried to understand the difference between child_process , cluster & worker_threads and then confused after finding another module called workerpool so could you tell the difference between worker_threads and workerpool in short, please?

Answer 1

workerpool provides a pool of worker threads that it uses to run things: threads that can be reused, a new thread doesn't have to be created every time. As it says in the second sentence of the npm description, it implements the worker pool pattern . worker_threads just provides a means of creating and using worker threads, it doesn't provide pooling. (Also, workerpool supports both Node.js and browsers, but worker_threads is of course Node.js specific.)
