njobs v1.0.4

NJOBS

Run some function, any function, on multiple threads up to the number of cores on your machine.

Usage

npm install njobs

const runConcurrently = require('njobs');

// second argument is the number of repetitions
// third argument is the number of threads
await runConcurrently(myfunc, 8, 4);
console.log("Done!");

Note: child processes attach a child=1 environment variable to the process to help you identify the main thread in more complicated code. Example function to determine whether you are in the main thread:

const isMain = () => {
  return !process.env.child;
};

Test

node test.js
