React Redux Starter Kit

Join the chat at https://gitter.im/davezuko/react-redux-starter-kit Build Status dependencies devDependency Status js-standard-style

This starter kit is designed to get you up and running with a bunch of awesome new front-end technologies, all on top of a configurable, feature-rich webpack build system that's already setup to provide hot reloading, CSS modules with Sass support, unit testing, code coverage reports, bundle splitting, and a whole lot more.

The primary goal of this project is to remain as unopinionated as possible. Its purpose is not to dictate your project structure or to demonstrate a complete sample application, but to provide a set of tools intended to make front-end development robust, easy, and, most importantly, fun. Check out the full feature list below!

Finally, This project wouldn't be possible without the help of our many contributors, so thank you for all of your help.

Features

Requirements

  • node ^4.2.0
  • npm ^3.0.0

Getting Started

After confirming that your development environment meets the specified requirements, you can follow these steps to get the project up and running:

$ git clone https://github.com/davezuko/react-redux-starter-kit.git
$ cd react-redux-starter-kit
$ npm install                   # Install project dependencies
$ npm start                     # Compile and launch

If everything works, you should see the following:

While developing, you will probably rely mostly on npm start; however, there are additional scripts at your disposal:

npm run <script> Description
start Serves your app at localhost:3000. HMR will be enabled in development.
compile Compiles the application to disk (~/dist by default).
dev Same as npm start, but enables nodemon for the server as well.
dev:no-debug Same as npm run dev but disables devtool instrumentation.
test Runs unit tests with Karma and generates a coverage report.
test:dev Runs Karma and watches for changes to re-run tests; does not generate coverage reports.
deploy Runs linter, tests, and then, on success, compiles your application to disk.
deploy:dev Same as deploy but overrides NODE_ENV to "development".
deploy:prod Same as deploy but overrides NODE_ENV to "production".
lint Lint all .js files.
lint:fix Lint and fix all .js files. Read more on this.

Application Structure

The application structure presented in this boilerplate is fractal, where functionality is grouped primarily by feature rather than file type. Please note, however, that this structure is only meant to serve as a guide, it is by no means prescriptive. That said, it aims to represent generally accepted guidelines and patterns for building scalable applications. If you wish to read more about this pattern, please check out this awesome writeup by Justin Greenberg.

Development

Developer Tools

We recommend using the Redux DevTools Chrome Extension. Using the chrome extension allows your monitors to run on a separate thread and affords better performance and functionality. It comes with several of the most popular monitors, is easy to configure, filters actions, and doesn’t require installing any packages.

However, adding the DevTools components to your project is simple. First, grab the packages from npm:

npm i --save-dev redux-devtools redux-devtools-log-monitor redux-devtools-dock-monitor

Then follow the manual integration walkthrough.

Routing

We use react-router route definitions (<route>/index.js) to define units of logic within our application. See the application structure section for more information.

Testing

To add a unit test, simply create a .spec.js file anywhere in ~/tests. Karma will pick up on these files automatically, and Mocha and Chai will be available within your test without the need to import them. If you are using redux-cli, test files should automatically be generated when you create a component or redux module.

Coverage reports will be compiled to ~/coverage by default. If you wish to change what reporters are used and where reports are compiled, you can do so by modifying coverage_reporters in ~/config/index.js.

Deployment

Out of the box, this starter kit is deployable by serving the ~/dist folder generated by npm run deploy (make sure to specify your target NODE_ENV as well). This project does not concern itself with the details of server-side rendering or API structure, since that demands an opinionated structure that makes it difficult to extend the starter kit. However, if you do need help with more advanced deployment strategies, here are a few tips:

Static Deployments

If you are serving the application via a web server such as nginx, make sure to direct incoming routes to the root ~/dist/index.html file and let react-router take care of the rest. The Koa server that comes with the starter kit is able to be extended to serve as an API or whatever else you need, but that's entirely up to you.

Heroku

More details to come, but in the meantime check out this helpful comment by DonHansDampf addressing Heroku deployments.

Build System

Configuration

Default project configuration can be found in ~/config/index.js. Here you'll be able to redefine your src and dist directories, adjust compilation settings, tweak your vendor dependencies, and more. For the most part, you should be able to make changes in here without ever having to touch the actual webpack build configuration.

If you need environment-specific overrides (useful for dynamically setting API endpoints, for example), you can edit ~/config/environments.js and define overrides on a per-NODE_ENV basis. There are examples for both development and production, so use those as guidelines. Here are some common configuration options:

Key Description
dir_src application source code base path
dir_dist path to build compiled application to
server_host hostname for the Koa server
server_port port for the Koa server
compiler_css_modules whether or not to enable CSS modules
compiler_devtool what type of source-maps to generate (set to false/null to disable)
compiler_vendor packages to separate into to the vendor bundle

Root Resolve

Webpack is configured to make use of resolve.root, which lets you import local packages as if you were traversing from the root of your ~/src directory. Here's an example:

// current file: ~/src/views/some/nested/View.js 
// What used to be this: 
import SomeComponent from '../../../components/SomeComponent'
 
// Can now be this: 
import SomeComponent from 'components/SomeComponent' // Hooray! 

Globals

These are global variables available to you anywhere in your source code. If you wish to modify them, they can be found as the globals key in ~/config/index.js. When adding new globals, make sure you also add them to ~/.eslintrc.

Variable Description
process.env.NODE_ENV the active NODE_ENV when the build started
__DEV__ True when process.env.NODE_ENV is development
__PROD__ True when process.env.NODE_ENV is production
__TEST__ True when process.env.NODE_ENV is test
__DEBUG__ True when process.env.NODE_ENV is development and cli arg --no_debug is not set (npm run dev:no-debug)
__BASENAME__ history basename option

Styles

Both .scss and .css file extensions are supported out of the box and are configured to use CSS Modules. After being imported, styles will be processed with PostCSS for minification and autoprefixing, and will be extracted to a .css file during production builds.

Server

This starter kit comes packaged with an Koa server. It's important to note that the sole purpose of this server is to provide webpack-dev-middleware and webpack-hot-middleware for hot module replacement. Using a custom Koa app in place of webpack-dev-server makes it easier to extend the starter kit to include functionality such as API's, universal rendering, and more -- all without bloating the base boilerplate.

Production Optimization

Babel is configured to use babel-plugin-transform-runtime so transforms aren't inlined. Additionally, in production, we use react-optimize to further optimize your React code.

In production, webpack will extract styles to a .css file, minify your JavaScript, and perform additional optimizations such as module deduplication.
