waitEach

A modern, lightweight async forEach utility for JavaScript and TypeScript.

waitEach enables asynchronous iteration over arrays with await support. It can be used as a standalone function or globally installed on Array.prototype for more convenient syntax in both Node.js and browser environments.

Features

• ✅ Asynchronous forEach with await support
• ✅ Works in Node.js and browser environments
• ✅ Optional global installation via Array.prototype.waitEach
• ✅ Fully typed for TypeScript
• ✅ Tiny and dependency-free

Installation

npm install waitEach
# or
yarn add waitEach

Usage

Using as a standalone function

import { waitEach } from 'waitEach';

const numbers = [1, 2, 3];

await waitEach(numbers, async (num) => {
  await new Promise(resolve => setTimeout(resolve, 500));
  console.log(num);
});

console.log('Done!');

Installing globally on Array.prototype

import { install } from 'waitEach';

// Install globally
install();

const numbers = [1, 2, 3];
await numbers.waitEach(async (num) => {
  await new Promise(resolve => setTimeout(resolve, 500));
  console.log(num);
});

console.log('Done!');

TypeScript Support

waitEach is fully typed. If you use the install() method, TypeScript will recognize waitEach on all arrays automatically.
