React.js Boilerplate

Quick setup for new React.js applications featuring Redux, hot–reloading, PostCSS, react-router and Mocha.

---

Features

• Using react-hot-loader, your changes in the CSS and JS get reflected in the app instantly without refreshing the page. That means that the current application state persists even when you change something in the underlying code! For a very good explanation and demo watch Dan Abramov himself talking about it at react-europe.

• Redux is a much better implementation of a flux–like, unidirectional data flow. Redux makes actions composable, reduces the boilerplate code and makes hot–reloading possible in the first place. For a good overview of redux check out the talk linked above or the official documentation!

• PostCSS is like Sass, but modular and capable of much more. PostCSS is, in essence, just a wrapper for plugins which exposes an easy to use, but very powerful API. While it is possible to replicate Sass features with PostCSS, PostCSS has an ecosystem of amazing plugins with funcionalities Sass cannot even dream about having.

• Unit tests should be an important part of every web application developers toolchain. Mocha checks your application is working exactly how it should without you lifting a single finger. Congratulations, you just won a First Class ticket to world domaination, fasten your seat belt please!

• react-router is used for routing in this boilerplate. Using the new, and currently unreleased, 1.0 version, react-router makes routing really easy to do and takes care of a lot of the work. Since the version is not officially out yet, the documentation is not fully finished, but by far finished enough to work for most needs.

Getting started

1. Clone this repo using git clone git@github.com:mxstbr/react-boilerplate.

2. Delete the existing git repository by running rm -rf .git.

3. Initialize a new git repository with git init, git add . and git commit -m "Initial commit".

4. Run npm install to install the dependencies.

5. Run npm start to start the local web server.

6. Go to http://localhost:3000 and you should see the app running!

Building & Deploying

1. Run npm run build, which will compile all the necessary files in a build folder.

2. Upload the contents of the build folder to your web server.

3. ?????? (You figure this part out)

4. Profit!

CSS

The CSS modules found in the css subfolders all get imported into the main.css file, which get inlined and minified into the compiled.css file. To add/change the styling, either write the CSS into the appropriate module or make a new one and @import it in the main.css file at the appropriate place.

PostCSS Plugins

The boilerplate uses PostCSS, and includes a few plugins by default:

• postcss-import: Inlines @imported stylesheets to create one big stylesheet.

• postcss-simple-vars: Makes it possible to use `$variables in your CSS.

• postcss-focus: Adds a :focus selector to every :hover.

• autoprefixer-core: Prefixes your CSS automatically, supporting the last two versions of all major browsers and IE 8 and up.

• cssnano: Optimizes your CSS file. For a full list of optimizations check the offical website.

• postcss-reporter: Makes warnings by the above plugins visible in the console.

For a full, searchable catalog of plugins go to postcss.parts.

Folder Structure

The boilerplate comes with a basic folder structure to keep the CSS files organised. This is what the folders are for:

• base: Global styling, e.g. setting the box–model for all elements

• components: Component specific styling, e.g. buttons, modals,...

• layout: Global layouts, e.g. article, homepage,...

• utils: Utility files, e.g. variables, mixins, functions,...

• vendor: External files, e.g. a CSS reset

JS

All files that are imported/required somewhere get compiled into one big file at build time. (build/bundle.js) Webpack automatically optimizes your JavaScript with UglifyJS, so you do not have to worry about that.

Folder Structure

The folder structure of the JS files reflects how Redux works, so if you are not familiar with Redux check out the official documentation.

• actions: Actions get dispatched with this/these utility module(s)

• components: The main JS folder. All your React components should be in this folder, for big projects they might be grouped into seperate subfolders. E.g. a navigation component Nav.react.js

• constants: Action constants need to be defined in this/these utility module(s)

• reducers: Reducers manage the state of an app, basically a simplified implementation of Stores in Flux. For an introduction to reducers, watch this talk by @gaearon.

Testing

Unit tests live in the test directory, and are run with npm test. There are two files in there already, testing that the current AppActions and Reducers are working correctly. Should you be stuck and have no idea what is going on check out the official Mocha documentation!
