Node.js and Browser polyfill gap

webpack and browserify user polyfill libraries for in-browser usage.

For example, webpack and browserify alias assert module to commonjs-assert in browser-env.

polyfill library

• webpack:
  • webpack/node-libs-browser: The node core libs for in browser usage.
• browserify:
  • substack/browserify-handbook: how to build modular applications with browserify
  • node-browserify/builtins.js at master · substack/node-browserify

Issues

• webpack: Incompatibility between Node.js core libs and webpack's lib · Issue #78 · webpack/node-libs-browser

Purpose

Recently, Node.js have upgraded own core module like assert. But, polyfill module like commonjs-assert does not follow the breaking change.

This repository aim to collect the gap issue between Node.js and Browser polyfills.
