Babel React Koa - Hot Universal Boilerplate

Breko Hub

Breko hub is a github repository that helps anyone create new JavaScript applications. Giving you a technically sound and well tested starting point for your application.

Why?

Create-React-App, Razzle, NextJS, etc... are fantastic alternatives!

The reason for Breko-hub is that it comes with some extras:

• test setup for integration on client and server
• test setup with additional helpers
• config management
• accessibility features on routing
• code splitting configuration
• configuration for linting
• it's not a framework, tool or library -- so everything is transparent!

Why not?

• The community around the alternatives are much bigger!
• There's more exposed configuration
• The documentation is lacking because
• tomatau: "I might stop supporting it one day, although I don't intend to!"
• The alternatives have some very nice features!

Documentation

Features

• Quick setup universal SPAs
• Universal redux architecture
• Hot reloading of CSS-modules
• Fast server side hot updates
• Babel 7 codebase everywhere
• A comprehensive integration and unit test suite
• A lucid code-base
• Great debugging tools!

Prerequsits

Breko-hub will only work on node version 6 and above as it is making use of Koa v2 along with polyfills for async/await syntax. To make it work on a lower version of node, the runtime compilation would need to be applied to koa and other node_modules.

Quick Start

Use the following commands to get started on your new app using breko-hub.

git clone --depth=1 [email protected]:tomatau/breko-hub.git <directory-name>
cd <directory-name>
rm -rf .git
git init
npm i
mv example.env .env
npm start

With the default .env file, this will start your application in development mode on port 9001. It also provides a configuration for running the debugger with a useful console output.

Open a browser window at localhost:9001.

You'll see example routes that demonstrate API calls and flash messages after redirects.

You can remove the example code for a cleaner starting point by running:

npm run remove-examples

This is a one time operation that can't be undone, it's also advised to run this before you start making any changes as it will hard replace some ./src files.

Blog

There is also a new blog that documents some of the techniques used in breko-hub. The blog was also created using breko-hub as a starting point.

Libraries

Breko hub uses the following libraries at its core:

Build tools

• webpack - A module bundler.
• babel - A JavaScript compiler.
• webpack-isomorphic-tools - Library for isomorphic rendering.

Server

• koa - A lightweight server framework.
• koa-router - Router middleware for koa.
• socket.io - A node engine for WebSocket communication.
• redux-via-socket.io - An adapter for sharing redux actions over WebSockets.

Universal Application

• react - A library for building interfaces.
• redux - A library for state management.
• react-router - A routing library for React.
• connected-react-router - Binding between react-router and redux.
• redux-saga - Side effect management for redux.
• reselect - A library for creating state selectors.
• redux-promise-middleware - A redux middleware for creating asynchronous actions.

Utility

• lodash - A popular modular utility library.
• ramda - A modular utility library focused on functional programming.

Styling

• SCSS - A popular CSS preprocessor.
• PostCSS - CSS transformations with JavaScript.
• css-modules - A build step for modular, local scoped CSS management.

Commands

Developing

npm run start [-- --open]

Builds and serves app with hot reloading and debugging support.

Build client-side app

Change your NODE_ENV to "production", you can do this is .env file or your hosted environment.

npm run build

Creates bundles and assets into ./src/static directory. Reads .env but always uses production Webpack configuration.

Start the server in production

Set the NODE_ENV flag to production in your .env file.

npm start

Expects bundles and assets to exist in the ./src/static directory. Runs the server in production mode.

Unit test single run

npm run test:unit

Runs the test suite in a node environment through mocha, once.

integration tests run

npm run test:int

Runs integration tests inside ./test/integration directory.

Lint

npm run lint:js
npm run lint:styles

Reads .eslintrc and sass-lint.yml for linting configurations.

Coverage

npm run coverage
npm run coverage:check

Reads .istanbul.yml for thresholds in check.

Unit test development server (BROKEN)

npm run test:server

Start a test server using Mocha and Webpack-middleware. Provides a browser based testing environment. Loading tests from within ./src where extension is .test.js.

Configuration

Change anything you want! It's all exposed and for you! <3

Docker

There's a starting docker images you can use to get going. You'll probably wanr to modify the Dockerfile to your needs.

# production image built with assets
$ docker build --compress -t your-username/your-app-name .
# runs `npm start` with port at 9001
$ docker run -p 9001:9001 your-username/your-app-name
