What is workerpool?

The workerpool npm package is a robust solution for offloading CPU intensive tasks to worker threads. It allows you to create a pool of workers and manage the execution of tasks in parallel, which can significantly improve the performance of Node.js applications that need to handle heavy computational work.

What are workerpool's main functionalities?

Creating a worker pool and executing tasks

This code sample demonstrates how to create a pool of workers and execute a simple 'add' function in a worker thread. The 'exec' method is used to send the task to an available worker and returns a promise that resolves with the result.

const workerpool = require('workerpool');
const pool = workerpool.pool();

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

pool.exec(add, [5, 7])
  .then(function (result) {
    console.log('Result: ' + result); // prints 12
  })
  .catch(function (err) {
    console.error(err);
  })
  .then(function () {
    pool.terminate(); // terminate all workers when done
  });

Using a worker script

This code sample shows how to use a separate worker script file. The 'pool' method is given the path to a worker script, and the 'exec' method is used to call a specific exported function from that script, passing in any necessary arguments.

const workerpool = require('workerpool');
const pool = workerpool.pool(__dirname + '/myWorker.js');

pool.exec('heavyComputation', [largeDataSet])
  .then(function (result) {
    console.log('Computation result: ' + result);
  })
  .catch(function (err) {
    console.error(err);
  })
  .then(function () {
    pool.terminate();
  });

Handling timeouts

This code sample illustrates how to handle task timeouts. The 'exec' method accepts an options object where you can specify a 'timeout' in milliseconds. If the task does not complete within the specified time, the promise is rejected.

const workerpool = require('workerpool');
const pool = workerpool.pool();

pool.exec('longRunningTask', [inputData], { timeout: 10000 })
  .then(function (result) {
    console.log('Task result: ' + result);
  })
  .catch(function (err) {
    console.error('Task timed out or other error:', err);
  })
  .then(function () {
    pool.terminate();
  });
