About

There may have been times where you would like to use an async function inside a forEach loop.

[1, 2, 3, 4].forEach(async (num) => {
    await someAsyncFunction(num);
});

As we know, the above example does not work. @async/foreach is a no frills, no dependencies module that makes iterating with async functions easier. @async/foreach takes advantage of Promise.all under the hood, so your invocations will run concurrently.

Usage

const asyncForEach = require('@async/foreach');
const fs = require('fs');

(async () => {

    const files = ['./path/to/file1.js', './path/to/file2.js', './path/to/file3.js'];

    const filesContent = await asyncForEach(files, async (file, index, array) => {
        console.log('The current index in the array:', index);
        console.log('The entire array:', array);
        await fs.readFile(file, 'utf8');
    });

    // Prints the contents of the files read
    console.log(filesContent);
})();
