    Guide on how to create and set up a Dockerized web app using Django REST APIs and ReactJS

Hopefully this will answer "How do I setup or start a Django project using REST Framework and ReactJS?"
This is a guide to show you step by step how this can be setup.  If you just want to get started, use the cookiecuter I set up cookiecutter-django-reactjs.  It basically is a fork of pydanny's cookiecutter, just added the front-end stuff :).
I created this because it was SUCH a pain in the ass setting up a project using all the latest technologies.
After some research, I figured it out and have it working. The repo that implements this is located here. Feel free to use it as a boilerplate ;)
Main features:

Django REST APIs
ReactJS with Redux Pattern
Webpack module bundler manager
Hot Reloading of ReactJS components for quicker development
Dockerized

NOTE: This guide was built using:

Django 1.10.2
Django REST Framework 3.4.7
NodeJS 6.7.0 with NPM 3.10.7
ReactJS 15.3.2
Redux 3.6.0
Webpack 1.13.2
Karma 1.3.0
Mocha 3.0.2

1. Setting up your machine

2. Setup version control with Git

3. Create dot files for project

4. Set up PostgreSQL database

5. Create a Virtual Environment for Python

6. Create Python requirements and install local dependencies

7. Setup Django project

8. Setup NodeJS project

9. Setup Webpack as front-end module bundler

10. Wire up Django/ReactJS application

11. Setup Karma and Mocha for running JavaScript Unittests

12. Customize NodeJS commands for ease of use

13. Dockerize application

14. Add Helpful Utilities for Consuming Django APIs with React

              Step02.md
            
          
    Setup version control with Git

Initialize git repository

git init

Create a GitHub or GitLab repository

I recommend using GitHub or GitLab for version control.
Once you have an account, create a repository so you can push all your code.
Push your code to your online repository

git add .
git commit -m "first commit"
git remote add origin https://github.com/[fill-in-here].git
git push -u origin master


## Step03.md

      
    Raw
  

              Step03.md
            
          
    Create dot files for project

EditorConfig

EditorConfig helps developers define and maintain consistent coding styles between different editors and IDEs. This file will initialize the coding style for this project.
EditorConfig settings based on:

PEP 0008
AirBnB JavaScript Style Guide

Example .editorconfig file
root = true

# Unix-style newlines with a newline ending every file
[*]
charset = utf-8
end_of_line = lf
insert_final_newline = true
trim_trailing_whitespace = true

# Python settings
[*.py]
line_length=120
indent_style = space
indent_size = 4

# JavaScript, JSX, CSS, SCSS, HTML settings
[*.{js,jsx,css,scss,html}]
indent_style = space
indent_size = 2

# Markdown settings
[*.md]
trim_trailing_whitespace = false

# Config files
[*.conf]
indent_style = space
indent_size = 2

Flake8

Flake8 is a is a wrapper around these tools: PyFlakes. pep8. It is a linting utility for Python. When used together with Atom, Atom Linter Plugin and Atom Flake8 Plugin, this will mark source code that doesn't conform to settings in .flake8 file.
Example .flake8 file:
[flake8]
max-line-length = 125

ESLint

The pluggable linting utility (tool to verify code quality) for JavaScript and JSX. When used together with Atom, Atom Linter Plugin and Atom ESLint Plugin, this will mark mark source code that doesn't conform to settings in .eslintrc file.
ESLint settings based on:

AirBnB JavaScript Style Guide

Example .eslintrc file:
{
  "extends": "airbnb",
  "ecmaFeatures": {
    "jsx": true,
    "modules": true
  },
  "env": {
    "browser": true,
    "es6": true,
    "node": true
  },
  "parser": "babel-eslint",
  "rules": {
    "react/jsx-uses-react": 2,
    "react/jsx-uses-vars": 2,
    "react/react-in-jsx-scope": 2,
    "no-var": 0,
    "vars-on-top": 0,
    "comma-dangle": 0,
    "arrow-body-style": ["error", "as-needed"],
    "import/no-extraneous-dependencies": ["error", {"devDependencies": true}],
    "max-len": ["error", { "comments": 120, "code": 120 }],
    "no-console": ["error", { "allow": ["warn", "error"] }],
    "no-unused-expressions": ["error", { "allowShortCircuit": true }]
  },
  "plugins": [
    "react"
  ]
}
GitIgnore settings

This will tell Git which files to ignore for version control.
Example .gitignore file:
# virtual environments
venv

# Python files
*.pyc
__pycache__

# Python Notebook dot files
.ipynb*

# Secret environment settings
.env
env

# Node and Webpack files
node_modules
npm-debug.log
webpack-stats*

# Static assests
staticfiles
static_cdn
media_cdn

# Ignore sqlite
db.sqlite3

# Apple files
.DS_Store

DockerIgnore settings

This will tell Docker what files to ignore.
Example .dockerignore file:
# virtual environments
venv

# Python files
*.pyc
__pycache__

# Python Notebook dot files
.ipynb*

# Secret environment settings
.env
env

# Node and Webpack files
node_modules
npm-debug.log

    Set up PostgreSQL database

On MacOSX

Install Postgres

On MacOSX we can use the Postgress App.  Just download and move the app into your Applications folder. Follow the instructions, its the easiest way I have seen to set up PostgresSQL!
Create an optimized user for our Django projects

Login to the database from the terminal using:
psql

CREATE USER django WITH PASSWORD '[password]';
ALTER ROLE django SET client_encoding TO 'utf8';
ALTER ROLE django SET default_transaction_isolation TO 'read committed';
ALTER ROLE django SET timezone TO 'UTC';
ALTER USER django CREATEDB;
Create a database for this specific Django project

Login to the database from the terminal using:
psql

CREATE DATABASE [project-name];
GRANT ALL PRIVILEGES ON DATABASE [project-name] TO django;

              Step05.md
            
          
    Create a Virtual Environment

It’s common practice to use a virtual environment for your Python projects in order to create self-contained development environments. The goal of pyenv is to prevent different versions of Python and libraries/packages from messing with each other. It’s like an isolated, soundproof room within your home where you can scream as loud as you want, about anything you want, and nobody else outside that room can hear it.
Use pyenv-virtualenv to create a virtual environment for your project:
pyenv virtualenv [project-name]
pyenv activate [project-name]

Create environment variables file - .env

This file will serve as environment variables that will serve our project. Django and Docker mostly will use this file.
Here is an example of .env file:
SECRET_KEY=[secret-key]
DEBUG=true
DJANGO_SETTINGS_MODULE=django_config.settings.local
ALLOWED_HOSTS=localhost 127.0.0.1 0.0.0.0
DATABASE_URL=postgres://django:[password]@localhost:5432/[project-name]

MAILGUN_API_KEY=[mailgun-api-key]
MAILGUN_DEFAULT_FROM_EMAIL=[email]

POSTGRES_PASSWORD=[password]
POSTGRES_USER=django
POSTGRES_DB=[project-name]

EMAIL_PORT=1025
EMAIL_HOST=localhost
EMAIL_BACKEND=django.core.mail.backends.smtp.EmailBackend
DEFAULT_FROM_EMAIL=[email]

    Setup Django project

Initialize Django project

I always start Django projects the same way, just so it can create the initial folder as django_config.  This is just personal perference on how I like to structure Django projects.
django-admin startproject django_config .

Reconfigure Django settings into a Python module

mkdir django_config/settings
touch django_config/settings/__init__.py
mv django_config/settings.py django_config/settings/base.py

Configure Base Django settings - ./django_configs/settings/base.py

    Setup Webpack as front-end module bundler

Webpack is module bundler.  It bundles all JavaScript, JSX, etc. code for our project and manages our codebase to be split into bundles to be loaded in in our different environments.
This also includes some goodies like hot-reloading ;).  This is extremely convienent when developing React components.
Create our Webpack directory

mkdir webpack

Create our base configuration for Webpack - webpack.base.config.js

module.exports = {

  module: {
    loaders: [{
      test: /\.(js|jsx)$/,
      exclude: /node_modules/,
      loader: 'babel-loader',

    }]
  },

  resolve: {
    modulesDirectories: ['node_modules'],
    extensions: ['', '.js', '.jsx']
  }
};
Create local configuration for Webpack - webpack.local.config.js

var path = require('path');
var BundleTracker = require('webpack-bundle-tracker');
var webpack = require('webpack');
var config = require('./webpack.base.config.js');

config.entry = {
  main: [
    'webpack-dev-server/client?http://0.0.0.0:3000',
    'webpack/hot/only-dev-server',
    'react-hot-loader/patch',
    path.join(__dirname, '../static/js/src/main/index')

config.devtool = 'inline-sourcemap';
config.output = {

      NODE_ENV: JSON.stringify('development'),
      BASE_URL: JSON.stringify('http://0.0.0.0:8000/'),
    }
  })
];

config.module.loaders[0].query.plugins = ['react-hot-loader/babel'];

config.devServer = {
  inline: true,
  progress: true,
  hot: true,
  historyApiFallback: true,
  host: '0.0.0.0',
  port: 3000
};

module.exports = config;
Create Production configuration for Webpack - webpack.production.config.js

var path = require('path');
var webpack = require('webpack');
var BundleTracker = require('webpack-bundle-tracker');
var config = require('./webpack.base.config.js');

config.entry = {

    Wire up Django/ReactJS application

NOTE: I have made some changes to this. I wanted to include the redux-dev-tools library.  Refer to this commit to see the changes.
In this step, we will make sure Django and ReactJS are communicating. We will now be able to use Django as our backend server and ReactJS to handle all of the frontend.
Write placeholder React Component

Write a simple React component as a placeholder for now.
mkdir -p static/js/src/main/components/

./static/js/src/main/components/hello-world.jsx should look like this:
import React from 'react';

const HelloWorld = () => {
  return (
    <h1>Hello World!</h1>
  );
};

export default HelloWorld;
./static/js/src/main/index.jsx should look like this:
import React from 'react';
import ReactDOM from 'react-dom';
import { AppContainer } from 'react-hot-loader';
import HelloWorld from './components/hello-world';

ReactDOM.render(
  <AppContainer>
    <HelloWorld />
  </AppContainer>,
  document.getElementById('react-root')
);

if (module.hot) {
  module.hot.accept('./components/hello-world', () => {
    const HelloWorld = require('./components/hello-world').default;
    ReactDOM.render(
      <AppContainer>
        <HelloWorld />
      </AppContainer>,
      document.getElementById('react-root')
    );
  });
}
Update HTML template to enable hot reloading

We need to tell the Django template to load the latest javascript bundle.  Because we are using Django webpack loader, we can enable hot reloading during development ;).
The index.html page should now look like this:
{% extends 'base.html' %}
{% load staticfiles %}
{% load render_bundle from webpack_loader %}

{% block body %}
<div id="react-root"></div>
{% endblock body %}

{% block javascript %}
{% render_bundle 'main' %}

    Setup Karma and Mocha for running JavaScript Unittests

Karma is a spectular test runner for JavaScript.  Karma will allow a productive testing environment, one where we can just write the code and get instant feedback from our tests.
Setup Karma configuration - ./webpack/karma.config.js

var webpackConfig = require('./webpack.local.config.js');

webpackConfig.entry = {};

module.exports = function (config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',

    exclude: [],

    // preprocess matching files before serving them to the browser

    },

    // test results reporter to use
    // possible values: 'dots', 'progress'
    // available reporters: https://npmjs.org/browse/keyword/karma-reporter
    reporters: ['progress'],

    // web server port
    port: 9876,

    // enable / disable colors in the output (reporters and logs)
    colors: true,

    // level of logging
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_INFO,

    // enable / disable watching file and executing tests whenever any file changes
    autoWatch: true,
    autoWatchBatchDelay: 300,

    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['Chrome'],

    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: false,

    // Concurrency level
    // how many browser should be started simultaneous
    concurrency: Infinity,

    // Webpack
    webpack: webpackConfig,
    webpackServer: {
      noInfo: true
    }
  });
};
Setup testing structure for our project

We set this up with an example test because if not Karma will complain ;)
static/js/src/test_index.js:
var testsContext = require.context('.', true, /.spec$/);
testsContext.keys().forEach(testsContext);
static/js/src/example.spec.js:
import expect from 'expect';

describe('Something abstract', () => {
  it('works', () => {
    expect(1).toEqual(1);
  });
});

  "build-production": "webpack --config webpack/webpack.production.config.js --progress --colors",
  "watch": "webpack-dev-server --config webpack/webpack.local.config.js",

We will use Docker and Docker compose to make add containers for all of the services that run our web application.
Our application will consist of the following services

PostgreSQL database
Django
Node (only for development for hot reloading ;) )
Nginx

Development Docker environment

1. Create docker-compose-development.yml file:

version: '2'

volumes:
  postgres_data_dev: {}
  postgres_backup_dev: {}

services:
  postgres:
    container_name: postgres_server
    build: ./docker_compose/postgres

# This entrypoint is used to play nicely with the current cookiecutter configuration.
# Since docker-compose relies heavily on environment variables itself for configuration, we'd have to define multiple
# environment variables just to support cookiecutter out of the box. That makes no sense, so this little entrypoint
# does all this for us.

python /app/manage.py collectstatic --noinput
/usr/local/bin/gunicorn django_config.wsgi -w 4 -b 0.0.0.0:5000 --chdir=/app
3. Create NGINX docker-compose build

mkdir -p docker_compose/nginx

    Helpful utilities for dealing with Django APIs with React

We will create helpful utilities to consume APIsin a secure fashion. We will use the following libraries:

react-cookie
axios

Front-end utilities

1. Create utilities directory

mkdir -p static/js/src/utilities/

2. Create script to interact with application cookie

We will use the react-cookie library (Makes this so easy!). We will use Cross-Site Request Forgery (CSRF) token and JSON web token (JWT) to secure our application.
It will make our application safe against Cross-site scripting (XSS) and CSRF attacks by following these strategies:

Store JWT in a httpOnly and secure cookie
Use a CSRF token with any methods that alter data on the server (PUT, POST, DELETE, PATCH).
GET should NOT cause changes server side. This is reserved for PUT, POST, DELETE, PATCH methods.

Create the static/js/src/utilities/cookie.js file. It should look like this:
import cookies from 'react-cookie';


// This is the place where we can load elements from a cookie to be used in our app

// Django CRSF Token is stored in a cookie
const csrftoken = cookies.load('csrftoken');

// JWT is going to be saved into cookie
// cookies.save('jwt', response.data.token, { secure: true, httpOnly: true });
// Therefore it will automatically be sent in the header of all API requests
// JWT will NOT be accessible to JavaScript because it is httpOnly :)

export { csrftoken };
3. Create script to use to interact with Django APIs

We will use the axios library to set this up. Create the static/js/src/utilities/api.js file. It should look like this:
import axios from 'axios';
import * as cookie from './cookie';


const api = axios.create({
  baseURL: process.env.BASE_URL,
  timeout: 1000,
});

// CRSF token is needed in all requests that can make a change server side
api.defaults.headers.post['X-CSRFToken'] = cookie.csrftoken;
api.defaults.headers.put['X-CSRFToken'] = cookie.csrftoken;
api.defaults.headers.patch['X-CSRFToken'] = cookie.csrftoken;
// api.defaults.headers.delete['X-CSRFToken'] = cookie.csrftoken; // Currently axios can't set headers for DELETE

// Since we will only be using JSON APIs, add Content-Type: application/json to header as default
api.defaults.headers.post['Content-Type'] = 'application/json';
api.defaults.headers.put['Content-Type'] = 'application/json';
api.defaults.headers.patch['Content-Type'] = 'application/json';

// Since we will only be using JSON APIs, add Accept: application/json to header as default
api.defaults.headers.get.Accept = 'application/json';
api.defaults.headers.post.Accept = 'application/json';
api.defaults.headers.put.Accept = 'application/json';
api.defaults.headers.patch.Accept = 'application/json';

// JWT is going to be saved into cookie
// cookies.save('jwt', response.data.token, { secure: true, httpOnly: true });
// Therefore it will automatically be sent in the header of all API requests
// JWT will not be accessible to JavaScript because it is httpOnly :)

export default api;
NOTE: Currently axios does not allow setting headers on DELETE method. I raised this issue and it should be included in the next release.
