Example for React-ESC
universal-react-redux-starter-kit
This project is based onInstall dependencies, and check to see it works
$ 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. |
start:dev |
Same as start but overrides NODE_ENV to "development". |
start:prod |
Serves your app at localhost:3000 . Production environment. |
compile |
Compiles the application to disk (~/dist by default). |
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". |
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.

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:
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 with React-ESC (Easy to use Client and Server) who handles the complete server side and client rendering so you can focus on what you love.
