I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

react-app-rewire-micro-frontends

This package makes a couple of modifications to react-scripts 2.0 for the purpose of building microfrontends

Single chunk

In react-scripts v1, your JavaScript was always compiled to a single file. In version 2, code splitting is enabled by default, so your application will be split into several 'chunks' which can be loaded onto the page indepedently. This makes it much more difficult to dynamically download the required scripts into an HTML file other than the one that react-scripts generates. So this rewiring puts things back into a single chunk.

Externals

To save bandwidth, react and react-dom are excluded from the compiled code, and are expected to be present on the page as scripts instead.

Installation

Install required dependencies:

yarn add -D react-app-rewired react-app-rewire-micro-frontends

Edit your package.json scripts to use react-app-rewired instead of react-scripts.

Add this line to your package.json:

  "config-overrides-path": "node_modules/react-app-rewire-micro-frontends",

That's it! Your app should now be compiled to just /static/js/bundle.js in dev mode, or main.[hash].js for production builds, and in either case the compiled code will not include react or react-dom.
