ESM builds of React & React DOM (v16)

@pika/react & @pika/react-dom

ESM builds of React v16 & React DOM v16, published to NPM.
This repo is no longer maintained.

Why?

React & React-DOM are both written as Common.js, and rely on some funky dynamic logic that's difficult for ESM bundlers like Rollup to statically analyze.

This package used to be the only way to use React in an ESM-only environment. However, Snowpack v2.0+ introduced the ability to use the "react" & "react-dom" packages directly. These packages are no longer necessary for Snowpack. We'll even warn if you use them! This repo only exists now for projects that need native ESM or that don't support more advanced CJS upconversions (ex: Vite).

The React team is working on ESM support. Until then, you can install these drop-in replacements in your projects to get smaller, optimized production installs with Snowpack, Rollup, Webpack, and Parcel.

# Install with npm
