worker-promise

Provide a better (more elegant) method to use the worker thread of javascript.

Install

Yarn

yarn add worker-promise

Npm

npm i worker-promise

Usage

Example Code 1 (Without parameters)

import WorkerPromise from "worker-promise"

const worker = new WorkerPromise()

worker.then(() => {
  console.warn('I am running in worker thread!')

  return 'From Worker Thred: Hello'
}).then(result => {
  console.warn(result)
})

console.warn('I am running in main thread')

Also , you can use await

const result = await worker.then(() => {
  console.warn('I am running in worker thread!')

  return 'From Worker Thred: Hello'
})

console.warn(result)

Example Code 2 (With parameters)

You can use prepare() to set parameter(not support multily, or you can pack then into one object) before then()

import WorkerPromise from "worker-promise"

const worker = new WorkerPromise()

worker.provide({name: 'SIMU', age: 18}).then((param) => {
  console.warn('I am running in worker thread!')
  console.warn(`I know you are ${param.name}, and ${param.age} years old!`)

  return 'From Worker Thred: Hello'
}).then(result => {
  console.warn(result)
})

Also, you can can attach parameter after callback

const worker = new WorkerPromise()

const callback = (param) => {
  console.warn('I am running in worker thread!')
  console.warn(`I know you are ${param.name}, and ${param.age} years old!`)

  return 'From Worker Thred: Hello'
}

worker.then(callback, {name: 'SIMU', age: 18}).then(result => {
  console.warn(result)
})

Example Code 3 (With imported function)

import WorkerPromise from "worker-promise"
import { getName, getAge } from './user';

const worker = new WorkerPromise()

worker
  .provide([getName, getAge])
  .then(() => {
    return `Name: ${getName()}, Age: ${getAge()}`;
  }).then(result => {
    console.warn(result)
  })

Note: You must provide the function you used
