WorkerOut

Library that makes any operation async

Why?

No need to write much code to move some command to web worker. Just use a library!

Usage

Translating sync operation to async

let json = '{"a":{"b":{"c":"d"}}}'; // 40KB of JSON

// Sync
let parsed = JSON.parse(json); // Wait
alert(parsed);

// Async
let worker = new WorkerOut();
let parsed = worker.JSON.parse(json);
parsed.then(alert);

Using promises

let address = "https://cors-anywhere.herokuapp.com/";

// Promises
fetch(address)
    .then(response => response.text())
    .then(alert);

// Worker
let worker = new WorkerOut();
worker.fetch(address)
    .then(response => response.text())
    .then(alert);

Your functions

let json = '{"a":{"b":{"c":"d"}}}'; // 40KB of JSON

let parseAndDoCoolThings = json => {
    return Object.entries(JSON.parse(json)).length;
};

// Sync
alert(parseAndDoCoolThings(json));

// Async
let worker = new WorkerOut();
worker(() => parseAndDoCoolThings(json)).then(alert);

Passing data

let json = '{"a":{"b":{"c":"d"}}}'; // 40KB of JSON

let CoolClass = {};

CoolClass.parse = json => {
    return JSON.parse(json);
};
CoolClass.calculate = json => {
    return Object.entries(json).length;
};
CoolClass.getAnswer = json => {
    return CoolClass.calculate(CoolClass.parse(json)) + 41;
};

// Sync
alert(CoolClass.getAnswer(json));

// Async
let worker = new WorkerOut();
worker.CoolClass = CoolClass;
worker.CoolClass.getAnswer(json).then(alert);

Methods

1. Save and load data:

   worker.answer = 42;
   console.log(worker.answer); // 42
   

2. Call WorkerOut as a function to make it async:

   worker(() => answer); // Promise <42>
   

3. Call default functions:

   worker.JSON.parse("{}"); // Promise <Object {}>
