require-browser

The require-browser package gives you an easy-to-use require function for your browser that behaves the same as the one in Node.js.

Features

• Works without installation via npx
• Makes it easy to get started developing with modules now
• Works on Windows, Linux, and macOS
• Can later be replaced with Webpack or browserify with few or no code changes
• require("fs") works the same as in Node (via fs-remote)
• require("os"), require("buffer"), and other Node builtin modules will be automatically replaced with browser-compatible shims
• Supports lookup via node_modules, so you can use npm to manage your dependencies

require-browser is not suitable for use in production (it's insecure), but makes it easy to get started developing in the browser. Once you want to run your code in production, I suggest using Webpack to bundle your application.

Usage

You must have Node.js 8.12.0 or higher installed, then run the following in your terminal or command prompt:

npx require-browser

A server will start and further instructions will be printed in your terminal/command prompt:

Installation

If you want to install require-browser globally so you don't need to use npx, run the following in your terminal or command prompt:

npm install -g require-browser

Then you can run it without npx:

require-browser
