Package Exports

workers-pool

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (workers-pool) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

workers-pool

Creating truly asynchronus functions has never been easier!

The workers-pool package allows you to easily create a pool of workers, pass them some heavy tasks in the form of functions, and use them as if they were asynchronous Promise-based functions.

Important note 1: This is not yet stable, you may not use it for production!
Important note 2: Currently there is supports for only node environment!

Installing the package

npm i workers-pool

Usage

Method 1: Creating an asynchronous function

const Pool = require('workers-pool');
const {isMainThread} = require('worker_threads');
const pool = new Pool();

function add (a, b) {
    return a + b;
}
module.exports.add = add;

addAsync = pool.getAsyncFunc({func: add});

if (isMainThread){
    addAsync(2, 5)
    .then((result)=>{
        console.log(result) // output: 7
    }).catch(err => {
        console.log(error);
    });
}

Method 2: Executing a function on the fly

Another way to run functions on the fly is also available:

const Pool = require('workers-pool');
const {isMainThread} = require('worker_threads');
const pool = new Pool();

function add (a, b) {
    return a + b;
}

module.exports.add = add;

if (isMainThread){
    pool.enqueueTask({
        func: add, 
        params: [2, 5], 
        resolveCallback: (result) => {
            console.log(result) // output: 7
        },
        rejectCallback: (error) => {
            // Handle error
            console.log(error);
        }
    });
}

Getting status

You can also get the status of the pools:

const Pool = require('workers-pool');

Pool.status();     // brief info about the pools
Pool.status(true); // Verbose info about the pools
