task-invoker

A tiny TypeScript/JavaScript utility for scheduling asynchronous task execution with zero delay. Perfect for deferring function calls to the event loop without using setTimeout(fn, 0).

✨ Features

• 🌀 Run tasks asynchronously with zero delay
• ⚡ Lightweight and dependency-free
• 🛡️ Written in TypeScript with type definitions

📦 Installation

npm install task-invoker
# or
yarn add task-invoker
# or
pnpm add task-invoker

🚀 Usage

import { schedule } from 'task-invoker';

const foo = () => {
  console.log('Hello from async task!');
};

// Task will be executed asynchronously, with no artificial delay
schedule(foo);

console.log('This will log first.');

🛠️ How it Works

task-invoker leverages microtask or macrotask scheduling to queue your function for execution after the current call stack clears — without introducing unnecessary delays.

This means:

• No need for setTimeout(fn, 0)
• Works consistently across modern runtimes
• Ensures smoother async flows

📚 API

schedule(fn: (...args: any[]) => void): void

Schedules a function to run asynchronously.

• fn — function to execute

📖 Examples

Debouncing heavy tasks

import { schedule } from 'task-invoker';

window.addEventListener('resize', () => {
  schedule(() => {
    console.log('Window resized, handle expensive logic here');
  });
});

Async UI updates

schedule(() => {
  document.body.classList.add('loaded');
});
