I want to create a worker to send back an array as response to my main file, but I can't understand why the worker is not sending postMessage
to main. Here is some dummy code to explain
My main file:
const { Worker } = require('worker_threads')
const worker = new Worker('./workerFile.js')
worker.on('message', msg => console.log(msg))
My workerFile.js
this.postMessage('hello world!')
CodePudding user response:
I had to import parentPort
and then use it in workerFile.js:
const { parentPort } = require('worker_threads')
parentPort.postMessage('hello world!')
