uni-require

The require() function is not available for ESM package.

But there are situation you need to use it, for example the require.resolve() function.

While you can get back the functionality using import.meta, you will run into problems if you want to do dual packaging.

This library helps you in that regards by providing a uniform (thus uni-*) interface for it.

Install

# npm
npm install uni-require

# yarn
yarn add uni-require

# pnpm
pnpm add uni-require

# rush
rush add -p uni-require

Usage

The uniRequire() function is a ponyfill of the require() function.

As such, it can be used to import CJS package, but cannot be used to import ESM package.

Most of the time, you should use import to import both CJS and ESM package.

The main benefits provided by uniRequire() is the uniRequire.resolve().

CommonJS:

const uniRequire = require('uni-require')

// it can be used to load CommonJS package
const child_process = uniRequire('child_process')

// it can be used to resolve (but not load) ESM package
const chalkPath = uniRequire.resolve('chalk')

ESM:

import uniRequire from 'uni-require'

// it can be used to load CommonJS package
const child_process = uniRequire('child_process')

// it can be used to resolve (but not load) ESM package
const chalkPath = uniRequire.resolve('chalk')
