React Falcor Skeleton

A simple skeleton to start you off on your ReactJS project. Uses a Flux framework and Falcor for data.

Getting Started

Just clone the repo and install the necessary node modules:

$ npm install                   # Install Node modules listed in ./package.json (may take a while the first time)
$ npm install -g nodemon        # Install Nodemon
$ gulp                          # Compile and launch

Usage

gulp also gulp dev

Runs the webpack build system just like in compile but enables HMR. The webpack dev server can be found at localhost:3000.

gulp compile

Runs the Webpack build system with your current NODE_ENV and compiles the application to disk (~/dist). Production builds will fail on eslint errors (but not on warnings).

gulp test

Runs unit tests with Karma.

gulp deploy

Helper script to run tests and then, on success, compile your application.

Configuration

Basic project configuration can be found in ~/build/config.js. Here you'll be able to redefine your src and dist directories, as well as tweak what ports Webpack and WebpackDevServer run on.

Structure

The folder structure provided is only meant to serve as a guide, it is by no means prescriptive. It is something that has worked very well for me and my team, but use only what makes sense to you.

Components vs. Views vs. Layouts

TL;DR: They're all components.

This distinction may not be important for you, but as an explanation: A Layout is something that describes an entire page structure, such as a fixed navigation, viewport, sidebar, and footer. Most applications will probably only have one layout, but keeping these components separate makes their intent clear. Views are components that live at routes, and are generally rendered within a Layout. What this ends up meaning is that, with this structure, nearly everything inside of Components ends up being a dumb component.

Webpack

Configuration

The webpack compiler configuration is located in ~/build/webpack. When the webpack dev server runs, only the client compiler will be used. When webpack itself is run to compile to disk, both the client and server configurations will be used. Settings that are bundle agnostic should be defined in ~/build/config.js and imported where needed.

Vendor Bundle

You can redefine which packages to treat as vendor dependencies by editing vendor_dependencies in ~/config/index.js. These default to:

[
  'history',
  'react',
  'react-redux',
  'react-router',
  'redux-router',
  'redux',
  'redux-devtools',
  'redux-devtools/lib/react'
]

Aliases

As mentioned in features, the default Webpack configuration provides some globals and aliases to make your life easier. These can be used as such:

import MyComponent from '../../components/my-component'; // without alias
import MyComponent from 'components/my-component'; // with alias

  // Available aliases:
  actions     => '~/src/actions'
  components  => '~/src/components'
  constants   => '~/src/constants'
  containers  => '~/src/containers'
  layouts     => '~/src/layouts'
  reducers    => '~/src/reducers'
  routes      => '~/src/routes'
  services    => '~/src/services'
  styles      => '~/src/styles'
  utils       => '~/src/utils'
  views       => '~/src/views'

Globals

__DEV__

True when process.env.NODE_ENV is development

__PROD__

True when process.env.NODE_ENV is production

__DEBUG__

True when the compiler is run with --debug (any environment).

Styles

All .scss imports will be run through the sass-loader, extracted during production builds, and ignored during server builds. If you're requiring styles from a base styles directory (useful for generic, app-wide styles) in your JS, you can make use of the styles alias, e.g.:

// ~/src/components/some/nested/component/index.jsx
import `styles/core.scss`;

Furthermore, this styles directory is aliased for sass imports, which further eliminates manual directory traversing. An example nested .scss file:

// current path: ~/src/styles/some/nested/style.scss
// what used to be this:
@import '../../base';

// can now be this:
@import 'base';

Testing

To add a unit test, simply create .spec.js file anywhere in ~/test. All imports will be relative to the "~/src" directory. The entry point for Karma uses webpack's custom require to load all these files, and Jasmine will be available to you within your test without the need to import them.

Utilities

This boilerplate comes with two simple utilities (thanks to StevenLangbroek) to help speed up your Redux development process. In ~/client/utils you'll find exports for createConstants and createReducer. The former is pretty much an even lazier keyMirror, so if you really hate typing out those constants you may want to give it a shot. Check it out:

import { createConstants } from 'utils';

export default createConstants(
  'TODO_CREATE',
  'TODO_DESTROY',
  'TODO_TOGGLE_COMPLETE'
);

The other utility, create-reducer, is designed to expedite creating reducers when they're defined via an object map rather than switch statements. As an example, what once looked like this:

import { TODO_CREATE } from 'constants/todo';

const initialState = [];
const handlers = {
  [TODO_CREATE] : (state, payload) => { ... }
};

export default function todo (state = initialState, action) {
  const handler = handlers[action.type];

  return handler ? handler(state, action.payload) : state;
}

Can now look like this:

import { TODO_CREATE } from 'constants/todo';
import { createReducer } from 'utils';

const initialState = [];

export default createReducer(initialState, {
  [TODO_CREATE] : (state, payload) => { ... }
});
