Min-react-setup NPM

min-react-starter

A fairly minimal React app starter designed to facilitate comprehension of the underlying tools.

I wanted a boilerplate for setting up a new React project without the full array of tools and abstractions that come with create-react-app (CRA).

Inspiration

Some beginners don't grasp that "React is just JavaScript" because CRA and JSX make it feel like you're working with a magic framework. React is great because it's just a UI library. The aim of this project is to demystify React development and give the developer complete understanding, and thus control of the toolchain.

This boilerplate provides:

A hot-reloading development server
Bundling with webpack
Compiling with Babel
A basic HTML template (for html-webpack-plugin) and sample favicon
A production build script (literally yarn build)

Unlike CRA, min-react-starter doesn't include a bunch of comments in all the config/template code, so you won't have to go remove all those when you're making this your own. The code is still understandable because min-react-starter is less complex than CRA. Relatedly, min-react-starter does not include all the the functionality of CRA and is not a replacement.

I like to know exactly what is happening when I run yarn start and to faciliate this included only what I considered the cleanest base setup. When I start developing, I add packages and webpack loaders & plugins as needed.

Getting Started

Prerequisites

The following sections assume you have the following installed:

Node.js runtime
Yarn package manager

Usage

Install the dependency packages.

yarn install

Bundle and transform the input files (with webpack), start & open the development server, and serve the output.

yarn develop

What's Happening?

First, yarn develop runs the develop script in package.json (webpack-dev-server --hot --open --mode development)

This will use the configuration set in webpack-config.js

Next, webpack will bundle and transform the input from the src/index.js entrypoint (all modules and files imported here) using the loaders and plugins specified in webpack-config.js

min-react-starter uses only one loader and one plugin.

webpack-config.js specifies babel-loader which will transform all files with a .js extension using the babel configuration set in .babelrc.

webpack-config.js specifies the html-webpack-plugin, which will inject a script tag referencing the bundled JavaScript into the end of the <body> specified in public/index.html. It will also include a <link> to public/favicon.ico in the <head>.

Finally,* the development server will serve the built application using the configuration set in webpack-config.js (http://localhost:5000).

Production

yarn build

Bundles and transforms src files with webpack mode set to production. Outputs to /dist, which can then by served (e.g. by a CDN; I like Netlify).

Recommended additions

As your project grows, you'll likely want to add some features:

Additional webpack loaders (e.g. file-loader, css-loader, style-loader) (I often use styled-components, so I didn't want to include these by default)
A separate webpack.config.dev.js and webpack.config.prod.js (see https://webpack.js.org/guides/production/)
Add historyApiFallback: true to devServer in webpack.config.js for single index.html SPAs using the History API (which is also used by React Router).

Dependencies

This project only has two client dependencies, react and react-dom.

For the toolchain, we also need:

Babel (@babel/core, @babel/corepreset-env, @babel/corepreset-react, babel-loader)
webpack and webpack-dev-server (and webpack-cli)
html-webpack-plugin

The full list is given below, from package.json.
