Getting Started

Clone the repo and install the necessary node modules:

$ git clone https://github.com/hirako2000/react-hackathon-board.git
$ cd react-hackathon-board
$ npm install                   # Install Node modules listed in ./package.json (may take a while the first time)

Start mongodb

$ mongod

Start the node application (dev - hot module reloading)

$ npm run start:dev  # Compile and launch

Deploy and start for production (with npm)

$ npm run deploy  # Compile all to ./dist
$ npm run start:prod

Deploy and start for production (with pm2)

$ npm run deploy
$ pm2 start npm --name=react-hackathton-board -- start

Dev

Here's a brief summary of the three which will most likely be your bread and butter:

• Doing live development? Use npm run start:dev to spin up the dev server.
• Compiling the application to disk? Use npm run compile.

NOTE: This package makes use of debug to improve your debugging experience. For convenience, all of messages are prefixed with app:*. If you'd like to to change what debug statements are displayed, you can override the DEBUG environment variable via the CLI (e.g. DEBUG=app:* npm run start:dev) or tweak the npm scripts (betterScripts in package.json).

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

npm run...	Description
start:dev	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 run start:dev, 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.
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.

NOTE: Deploying to a specific environment? Make sure to specify your target NODE_ENV so webpack will use the correct configuration. For example: NODE_ENV=production npm run compile will compile your application with ~/config/_production.js.

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

CLI Generators

This project integrates with Redux CLI out of the box. If you used it to generate this project you have immediate access to the generators listed below (if you cloned/forked the project you have these features as well, but make sure to install the CLI first!).

Script	Description	Options
redux g dumb <comp name>	generates a dumb component and test file
redux g smart <smart name>	generates a smart connected component and test file
redux g layout <comp name>	generates functional layout component
redux g view <comp name>	generates a view component
redux g form <form name>	generates a form component (assumes redux-form)
redux g duck <duck name>	generates a redux duck and test file
redux g blueprint <new blueprint>	generates an empty blueprint for you to make
NOTE: redux-form is not a dependency by default. If you wish to use it make sure to npm i --save redux-form, or if you wish to modify the skeleton you can update the blueprint in ~/blueprints/form/files/....

All of these blueprints are available (and can be overridden) in the ~/blueprints folder so you can customize the default generators for your project's specific needs. If you have an existing app you can run redux init to set up the CLI, then make sure to copy over the blueprints folder in this project.

See the Redux CLI github repo for more information on how to create and use blueprints.

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

Vendor Bundle

You can add 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

Server

This app comes Koa 2 as server.

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.

NOTE: If you're importing styles from a base styles directory (useful for generic, app-wide styles), you can make use of the styles alias, e.g.:

// current file: ~/src/components/some/nested/component/index.jsx
import 'styles/core.scss' // this imports ~/src/styles/core.scss

Furthermore, this styles directory is aliased for sass imports, which further eliminates manual directory traversing; this is especially useful for importing variables/mixins.

Here's an example:

// current file: ~/src/styles/some/nested/style.scss
// what used to be this (where base is ~/src/styles/_base.scss):
@import '../../base';

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

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 (duck).

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/_base.js.

Deployment

Out of the box, this app is deployable by serving the ~/dist folder generated by npm run compile (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 app. However, if you do need help with more advanced deployment strategies, here are a few tips:

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 app is able to be extended to serve as an API or whatever else you need, but that's entirely up to you.

Troubleshooting

npm run dev:nw produces cannot read location of undefined.

This is most likely because the new window has been blocked by your popup blocker, so make sure it's disabled before trying again.

Babel Issues

Running into issues with Babel? Babel 6 can be tricky, please either report an issue or try out the [stable v0.18.1 release]

Babel Polyfill

By default this repo does not bundle the babel polyfill in order to reduce bundle size. If you want to include it, you can use this commit from jokeyrhyme as a reference.

Deployment Issues (Generally Heroku)

Make sure that your environment is installing both dependencies and devDependencies, since the latter are required to build the application.

High editor CPU usage after compilation

While this is common to any sizable application, it's worth noting for those who may not know: if you happen to notice higher CPU usage in your editor after compiling the application, you may need to tell your editor not to process the dist folder. For example, in Sublime you can add:

	"folder_exclude_patterns": [".svn",	".git",	".hg", "CVS",	"node_modules",	"dist"]

Thank You

This project wouldn't be possible without help from the community, so I'd like to highlight some project that helped getting started. Thank you all for your hard work, you've made my life a lot easier and taught me a lot in the process.
