MEAN Stack Development Starter

A MEAN stack development kit featuring Angular 2 (Router, Forms, Http, Services, Tests, E2E), Express, MongoDB (complete with Mongoose), Node, Redux, @ngrx/store PassportJS, Socket.IO, Karma, Protractor, Jasmine, Istanbul, Configuration, TypeScript, Typings, Sass, Docco, TsLint, Codelyzer, Hot Module Replacement, Material, and Webpack, as well as ES6/ES7 support for the back-end by datatype_void.

Walk through a complete tutorial that shows you how to build a simple todo app using this framework, check out Building A Single Page Todo App with MEAN--Including Angular 2

If you're looking to learn about Webpack and ES6 Build Tools check out ES6-build-tools

If you're looking to learn TypeScript see TypeStrong/learn-typescript

If you're looking to learn how to move your Angular 1.x directives over to Angular 2 see Migrating Directives to Angular 2

And always keep the Angular 2 docs at hand, because the times are always changing

This seed repo serves as an MEAN starter for anyone looking to get a MEAN fullstack app up and running with Angular 2, TypeScript(on the front-end), and ES6/ES7 (on the back-end) fast. Using Webpack for building our files and assisting with boilerplate. We're also using Protractor for our end-to-end story and Karma for our unit tests.

  • Best practices in file and application organization for Angular 2.
  • Ready to go build system using Webpack for working with TypeScript.
  • Hot module reloading for the front-end à la Webpack.
  • Angular 2 examples that are ready to go when experimenting with Angular 2.
  • A great MEAN seed repo for anyone who wants to start their project.
  • Testing Angular 2 code with Jasmine and Karma.
  • Coverage with Istanbul and Karma
  • End-to-end Angular 2 code using Protractor.
  • Type manager with Typings
  • Material Design with angular/material2
  • Sass preprocessor linting and compiling
  • Automatic documentation for all project related Sass, TypeScript, and JavaScript files with Docco; front-end and back-end

The rest of the stack features:

Quick start

Make sure you have Node version >= 4.0 and NPM >= 3

If you are located in China, use cnpm

https://awesomeopensource.com/project/cnpm/cnpm

Install the stack then edit app.ts inside /src/app/app.ts

# install vulgar-cli and the generator it hooks into
$ npm install -g vulgar-cli generator-vulgar

# initialize installer
$ vulgar init <nameOfApplication>

# change directory to new application root
$ cd <nameOfApplication>

# add required global libraries
$ npm install -g typings webpack webpack-dev-server concurrently

# install the repo with npm
# required only if you declined automated dependency installation
# during installation
$ npm install

# build code
$ npm run build

# start up the stack

# this command runs two commands in parallel via `concurrently`:
# `npm run server` starts up `webpack-dev-server` allowing for
# hot module reloading
# `npm` run watch` uses `webpack` to watch the necessary files
# and build on file change
$ npm start

# in a separate terminal:
# start `Express` server
$ gulp serve

Table of Contents

File Structure

We use the component approach in our starter. This is the new standard for developing Angular apps and a great way to ensure maintainable code by encapsulation of our behavior logic. A component is basically a self contained app usually in a single file or a folder with each concern as a file: style, template, specs, e2e, and component class. Here's how it looks:

Getting Started

Prerequisite Technologies

What you need to run this app:

Linux

If you're using ubuntu, this is the preferred repository to use...

$ curl -sL https://deb.nodesource.com/setup | sudo bash -
$ sudo apt-get update
$ sudo apt-get install nodejs

or use Node Version Manager to easily manage and update your node installations and global dependencies

Windows

  • Node.js - Download and Install Node.js, nodeschool has free node tutorials to get you started.
  • MongoDB - Follow the great tutorial from the mongodb site - "Install Mongodb On Windows"
  • Git - The easiest way to install git and then run the rest of the commands through the git bash application (via command prompt) is by downloading and installing Git for Windows

OSX

Ensure you are running the latest versions Node v4.x.x+ and NPM 3.x.x+

Dependencies

Once you have those, you should install these globals with npm install --global:

  • webpack ($ npm install --global webpack)
  • webpack-dev-server ($ npm install --global webpack-dev-server)
  • karma ($ npm install --global karma-cli)
  • protractor ($ npm install --global protractor)
  • typings ($ npm install --global typings)
  • typescript ($ npm install --global typescript)
  • concurrently ($ npm install --global concurrently)
  • mocha ($ npm install --global mocha)

Installing

  • $ npm install -g vulgar-cli generator-vulgar
  • $ vulgar init to install a new instance of the v#[email protected] MEAN stack framework
  • $ npm install -g typings webpack webpack-dev-server concurrently rimraf to install global dependencies
  • $ npm install to install all local dependencies
  • $ typings install to install necessary typings
  • $ npm run build to build necessary front-end code with Webpack
  • $ npm start to enable hot module reloading and build on file change
  • In a new terminal, node server to start the server for the first time

config.json

The server.conf.js file is expecting certain environment variables to be set within Node. The env.conf.js has functions to check whether the expected environment variables have been setup before proceeding to start up the rest of the server. It uses a file called config.json stored in the config directory that looks something like this:

{
  "ENV" : "development",
  # MAKE SURE PORT IS NOT 8080 OR WHATEVER THE WEBPACK
  # DEV SERVER PORT IS SET TO
  "PORT" : 3000,
  "MONGO_URI" : {
    "DEVELOPMENT" : "mongodb://[username:password]@host[:port]",
    "PRODUCTION" : "mongodb://[username:password]@host[:port]",
    "TEST" : "mongodb://[username:password]@host[:port]"
  },
  # Generate your own 256-bit WEP key here:
  # http://randomkeygen.com/
  # Note that you don't need to use specifically
  # this, but it will certainly suffice
  "SESSION_SECRET" : "355FC4FE9348639B4E4FED1B8E93C"
}

You should definitely change your `SESSION_SECRET` for even the most lackadaisical development effort.

A Quick Note About the config.json Object

This object is not absolutely required. You can pass these values in however you want, whether it is through the command line or some alternative method. This just provided me with an easy way of storing a couple of values that do not change often.

Running the app

After you have installed all dependencies and modified your config.json file, you can now run the app. First, you must start up the back-end server in a separate terminal using the gulp serve command. This will fire up our Express app using nodemon, which will watch for file changes and restart our backend when necessary. Next use the npm start command in the original terminal which runs two npm scripts in parallel: npm run server to start webpack-dev-server for building our front-end in the computer's memory, enabling hot module reloading; npm run watch to watch all of the front-end files and build them upon changes. You can now fire up your favorite web browser and visit the running application at localhost:8080!

server

# development
# package front-end files with Webpack and hot reload
# upon any changes
$ npm start
# use `Gulp` in a second terminal to run the Express
# app responsible for our back-end
$ gulp serve
# optionally use `Gulp` in a third terminal to auto
# generate documentation and lint `Sass`
$ gulp

# production
$ npm run build:prod
$ npm run server:prod

Other commands

start Express back-end

$ gulp serve

build documentation

$ gulp build:docs

watch and build documentation

$ gulp watch:docs

watch and lint sass

$ gulp watch:sass

build files

# development
$ npm run build:dev
# production
$ npm run build:prod

watch and build files

$ npm run watch

run tests

$ npm run test

watch and run our tests

$ npm run watch:test

run end-to-end tests

# make sure you have your server running in another terminal
$ npm run e2e

run webdriver (for end-to-end)

$ npm run webdriver:update
$ npm run webdriver:start

run Protractor's elementExplorer (for end-to-end)

$ npm run webdriver:start
# in another terminal
$ npm run e2e:live

Configuration

Configuration files live in config/. We are currently using mongooose, passportJS, webpack, mocha, karma, and protractor for different stages and parts of your full-stack application

TypeScript

To take full advantage of TypeScript with autocomplete you would have to install it globally and use an editor with the correct TypeScript plugins.

Use latest TypeScript compiler

TypeScript 1.7.x includes everything you need. Make sure to upgrade, even if you installed TypeScript previously.

$ npm install --global typescript

Use a TypeScript-aware editor

We have good experience using these editors:

Typings

When you include a module that doesn't include Type Definitions inside of the module you need to include external Type Definitions with Typings

Use latest Typings module

$ npm install --global typings

Custom Type Definitions

When including 3rd party modules you also need to include the type definition for the module if they don't provide one within the module. You can try to install it with typings

$ typings install node --save

If you can't find the type definition in the registry we can make an ambient definition in this file for now. For example

declare module "my-module" {
  export function doesSomething(value: string): string;
}

If you're prototyping and you will fix the types later you can also declare it as type any

declare var assert: any;

If you're importing a module that uses Node.js modules which are CommonJS you need to import as

import * as _ from 'lodash';

You can include your type definitions in this file until you create one for the typings registry see typings/registry

Frequently asked questions

  • What's the current browser support for Angular 2 Beta?

  • Why is my service, aka provider, is not injecting parameter correctly?

    • Please use @Injectable() for your service for typescript to correctly attach the metadata (this is a TypeScript problem)
  • How do I run protractor with node 0.12.x?

    • please check out this repo to use the old version of protractor #146
  • Where do I write my tests?

  • How do I start the app when I get EACCES and EADDRINUSE errors?

    • The EADDRINUSE error means the port 8080 is currently being used and EACCES is lack of permission for webpack to build files to ./dist/
  • How to use sass for css?

  • How do I test a Service?

  • How do I add vscode-chrome-debug support?

  • How do I make the repo work in a virtual machine?

  • What are the naming conventions for Angular 2?

  • How do I include bootstrap or jQuery?

  • I'm getting an error about not finding my module that I installed?

  • How do I async load a component?

    • { path: '/about', loader: () => require('es6-promise!./about/about')('About') }
    • Also see es6-promise-loader
  • Error: Cannot find module 'tapable'

    • Remove node_modules/ and run npm cache clean then npm install
  • RangeError: Maximum call stack size exceeded

    • This is a problem with minifying Angular 2 and it's recent JIT templates. If you set mangle to false then you should be good.
  • Why is the size of my app larger in development?

    • We are using inline source-maps and hot module replacement which will increase the bundle size.
  • If you are located in China, use cnpm

  • node-pre-gyp ERR in npm install (Windows)

    • install Python x86 version between 2.5 and 3.0 on Windows machines
