Usage

Before delving into the descriptions of each available npm script, here's a brief summary of the three which will most likely be your bread and butter:

• Doing live development? Use npm start to spin up the dev server.
• Compiling the application to disk? Use npm run compile.
• Deploying to an environment? npm run deploy can help with that.

Great, now that introductions have been made here's everything in full detail:

npm run...	Description
start	Spins up Koa server to serve 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 to automatically restart the server when server-related code is changed.
dev:nw	Same as npm run dev, but opens the redux devtools in a new window.
dev:no-debug	Same as npm run dev but disables redux devtools.
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".
flow:check	Analyzes the project for type errors.
lint	Lint all .js files.
lint:fix	Lint and fix all .js files. Read more on this.

Configuration

Basic project configuration can be found in ~/config/_base.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 webpack build configuration.

If you need environment-specific overrides (useful for dynamically setting API endpoints, for example), create a file with the name of target NODE_ENV prefixed by an _ in ~/config (e.g. ~/config/_production.js). This can be entirely arbitrary, such as NODE_ENV=staging where the config file is ~/config/_staging.js.

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

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.

Webpack

Vendor Bundle

You can redefine which packages to bundle separately by modifying compiler_vendor in ~/config/_base.js. These default to:

[
  'history',
  'react',
  'react-redux',
  'react-router',
  'react-router-redux',
  'redux'
]

Webpack 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/_base.js. When adding new globals, 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__	npm history basename option
