React-Base

A modular platform for Redux Isomorphic applications

This repository is a modular abstraction to build a ReactJS web application based on Redux paradigm. You can use it to quickly scaffold your React web application projects and development environments for these projects.

This seed should clarify how to wire up all the modules of your application, even when we understand that in some cases there must be some changes needed by the structure to fit your needs correctly

Overview

React-Base makes use of the latest tools to improve your workflow, and enables you to create future ready applications:

• Redux based architecture
• Isomorphic / Universal Javascript Apps
• Webpack 3 build configuration depending on enviroment
• Immutable data modeling using ImmutableJS
• Store middleware to handle request actions.
• Development & Production server using express and webpack-dev-server
• Hot Reload/Live Reload support for Js & Css using Webpack HMR
• Container and component generators using Yeoman
• JSX and ES6 transpilation using Babel
• Mocha as testing framework
• Enzyme/JsDom for unit/ui testing
• Nyc for code coverage
• PostCSS processing with isomorphic support.
• CssModules based
• Code Linting using Eslint
• Css Linting using CssLint
• Airbnb React Style Guide

Getting Started

To get you started, you need to meet the prerequisites, and then follow the installation instructions.

Prerequisites

React-Base makes use a number of NodeJS tools to initialize and test React-Base. You must have node.js 6.2.0 at least, and its package manager (npm) installed. You can get it from nodejs.org.

Installing

You can clone our Git repository:

$ git clone https://github.com/atSistemas/react-base.git

This method requires Git to be installed on your computer. You can get it from here.

Wiring up your development environment

Setting up React-Base is as easy as running:

$ npm install

This command will install all the required dependencies and start your development server, which takes care of all the changes you make to your code and runs all the awesome stuff that ends with your code automagically transpiled and running on your browser.

Please note that npm install is only required on your first start, or in case of updated dependencies.

Initializing development server

Once all the dependencies are installed, you can run $ npm run start to initialize your development server using webpack-dev-server express middleware.

The dev server uses HMR (Hot module replacement) that injects updated modules into the bundle in runtime. It's like LiveReload

Architecture

React-base is based on Redux paradigm so you can find all the typical entities of an Redux project like reducers , store, actions , etc.

There are four main folders:

• server contains React-Base development & production server based in express with Universal/Isomorphic support and custom middlewares like Gzip.

server
  api/ //Api mocks
  lib/ //Universal rendering files
  middleware/ //enviroment middleware
  statics/ //definition of  statics path
  templates/ //universal templates
    server  //Server  
    routing  //Routing middleware  

• webpack contains React-Base Webpack configuration separated by enviroment that allows to use different plugins and loaders in each target enviroment.

webpack
  webpack.common.config/ //Common config
  webpack.dev.config/ //Development config
  webpack.prod.config/ //Production config
  webpack.test.config/ //Testing config
  webpack.dll.config/ //Dll config

• src/base/ contains React-Base platform bootstrapping code.

base
  client/ //client bootstrap
  conf/ //Configuration files and Yeoman templates
  middleware/ //Redux Store middleware
  components/ //base components
  models/ //model index
  reducers/  //reducer index
  routes/ //routes index
  shared/ // shared base folder
    regenerators/ //index regenerators
    CreateActionType //Custom action type creator
    CreateReducer //Custom reducer creator
    ENV //Env handler
    Errors //Errors handler
    FetchData //Isomorfic data handler
    FileSystem //Filesystem manager
    JsDomSetup //JsDom Configuration FileSystem
    ModelHelper //Inmutable deserializators
    Regenerate // Regenerate indexes
  store/ //Store configuration and AppState definition
  types/ //Action request Types
  wp-plugins/ //Custom webpack plugins
  ...

• src/app/ is the place where to put your application source code.

React-Base uses a "featured based" distribution, so all the necessary code for each page/features is located in its own folder inside containers folder as in src/app/containers/myContainer

A container is a React component who contains other components, Redux entities, functions and store subscriptions. Each container is self-contained and represents a feature like "clients" or "products" and it contains all the necessary stuff.

app/
  containers/
    myContainer/
      api/ //api calls
      actionTypes/ //action types definition
      actions/ //action creators
      components/ //container components
      models/ //containers models using immutable
      reducers/ //container reducers
      index.ts //container component
  ...

Action Types

ActionTypes it's a representation using constants of your possible actions:

import { createActionType } from 'base';

export const ActionTypes = createActionType([
  'CLICK',
  'MAIN_CONTAINER',
  'MAIN_ERROR',
  'MAIN_REQUEST',
  'MAIN_SUCCESS',
  'LAZY_CONTAINER',
  'LOGIN',
]);

Actions

Actions are payloads of information witch represent that something happend in your application and send data from your application to your store:

clickHandler(id) {
    return {
      type: ActionTypes.USER_CLICK,
      payload: {
        id: id
      }
    };
}

React-Base include a Redux Store middleware to handle actions with service calls more easyly. You can define in the api folder of your container, an api call based in a fetch call:

  fetchUsers() {
    return fetch(url)
      .then(req => req.json())
      .then(data => data)
      .catch(err => err) 
  },

Then, in your action you can attach this service call in your action using the request param:

export function getPosts() {
  return {
    type: ActionTypes.USERS_REQUEST,
    request: api.fetchUsers()
  };
}

The request middleware will resolve the request param and dispatch a new action with "ACTION_SUCCESS" or "ACTION_ERROR" with the response of the request in the payload.

Reducers

Reducers describe how the state of your application changes in response to a new Action. React-Base uses a custom CreateReducer that allows to use separated reducers functions instead of "switch based" reducers.

import { createReducer } from 'base';

const click = (state, action) => {
  return state.update('mainData', (value) => action.payload);
};

const request = (state, action) => {
  return state;
};

const actionHandlers = {
  [ActionTypes.CLICK]: click,
  [ActionTypes.LOGIN]: login,
  [ActionTypes.MAIN_REQUEST]: request,
  [ActionTypes.MAIN_SUCCESS]: success,
};

export default CreateReducer(actionHandlers, new MainModel());

Models

Represents your model data using ImmutableJS Data Types and sets its initial state using setInitialState() function.

import { Record } from 'immutable';

const MainModel = new Record({
  display:0,
  operator:'',
  operation:'',
  prevValue: 0,
  nextValue: 0,
  newValue: false,
  resetDisplay: false,
});

function setInitialState(initialState) {
  return initialState.Maiin = new MainModel();
}

export { MainModel, setInitialState };

Generating a new container

React-base uses Yeoman to generate new application containers or components.

Fist of all you need to link yo:

$ npm run yo

Then, you can generate a new container run:

$ npm run generate:container

You'll be asked to provide a name for your container. After that, React-base will create all the necessary folder and file template structures you, and will rebuild the file indexes (routes, reducers, models, etc), so you don't have to worry about including all the required imports.

After that, you can access to your container from http://localhost:8000/myContainer

Regenerating indexes

You can rebuild the file indexes (reducers, models and routes) running $ npm run regenerate

Generating a new component

As with containers, React-base can automate components creation for you. To create a new component, just type:

$ npm run generate:component

Same as before, you will be asked for a component name, and after that React-base will do the rest, placing a component template under app/components, and rebuilding all the indexes.

Distribution

You can generate a complete distribution source ready for production enviroments.

Building your production application

$ npm run build:prod will create a minified version for your application, ready for production.

Running production server

$ npm run start:prod will run production enviroment of your application serving content from dist directory.

Testing your application

React base uses - Enzyme a testing utillity created by Airbnb for unit testing and Ui testing using Airbnb so you can run your ui testing without a browser.

You can write your tests normally using Mocha and Chai for assertions.

Running your tests

$ npm run test will perform your unit testing, or npm test:coverage to run your tests and display a code coverage report.

Generating code coverage

React base uses Nyc for code coverage and you can generate reports in console or icov/html format.

$ npm run test will perform your code coverage, generating an html report located in coverage/ folder.
