Getting Started

Dependencies

What you need to run this app:

• node and npm (brew install node)
• Ensure you're running the latest versions Node v6.x.x+ (or v7.x.x) and NPM 3.x.x+

If you have nvm installed, which is highly recommended (brew install nvm) you can do a nvm install --lts && nvm use in $ to run with the latest Node LTS. You can also have this zsh done for you automatically

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)
• typescript (npm install --global typescript)

Running the app

After you have installed all dependencies you can now run the app. Run npm run server to start a local server using webpack-dev-server which will watch, build (in-memory), and reload for you. The port will be displayed to you as http://0.0.0.0:3000 (or if you prefer IPv6, if you're using express server, then it's http://[::1]:3000/).

server

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

Other commands

build files

# development
npm run build:dev
# production (jit)
npm run build:prod
# AoT
npm run build:aot

hot module replacement

npm run server:dev:hmr

watch and build files

npm run watch

build Docker

npm run build:docker

Configuration

Configuration files live in config/ we are currently using webpack, karma, and protractor for different stages of your application

AoT Don'ts

The following are some things that will make AoT compile fail.

• Don’t use require statements for your templates or styles, use styleUrls and templateUrls, the angular2-template-loader plugin will change it to require at build time.
• Don’t use default exports.
• Don’t use form.controls.controlName, use form.get(‘controlName’)
• Don’t use control.errors?.someError, use control.hasError(‘someError’)
• Don’t use functions in your providers, routes or declarations, export a function and then reference that function name
• @Inputs, @Outputs, View or Content Child(ren), Hostbindings, and any field you use from the template or annotate for Angular should be public

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 2.1.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:

• Visual Studio Code
• Webstorm 10
• Atom with TypeScript plugin
• Sublime Text with Typescript-Sublime-Plugin

Types

When you include a module that doesn't include Type Definitions inside of the module you can include external Type Definitions with @types

i.e, to have youtube api support, run this command in terminal:

npm i @types/youtube @types/gapi @types/gapi.youtube

In some cases where your code editor doesn't support Typescript 2 yet or these types weren't listed in tsconfig.json, add these to "src/custom-typings.d.ts" to make peace with the compile check:

import '@types/gapi.youtube';
import '@types/gapi';
import '@types/youtube';

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 @types

npm install @types/node
npm install @types/lodash

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;
declare var _: any;
declare var $: 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 write your tests next to your component files. See /src/app/home/home.component.spec.ts
• How do I start the app when I get EACCES and EADDRINUSE errors?
  • The EADDRINUSE error means the port 3000 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?
  • See issue #130
• How do I add vscode-chrome-debug support?
  • The VS Code chrome debug extension support can be done via launch.json see issue #144
• How do I make the repo work in a virtual machine?
  • You need to use 0.0.0.0 so revert these changes #205
• What are the naming conventions for Angular?
  • please see issue #185 and PR 196
• How do I include bootstrap or jQuery?

• 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're in China
  • check out https://github.com/cnpm/cnpm

Deployment

Docker

To run project you only need host machine with operating system with installed git (to clone this repo) and docker and thats all - any other software is not needed (other software like node.js etc. will be automatically downloaded and installed inside docker container during build step based on dockerfile).

Install docker

MacOS:

brew cask install docker

And run docker by Mac bottom menu> launchpad > docker (on first run docker will ask you about password)

Ubuntu:

sudo apt-get update
sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
sudo apt-add-repository 'deb https://apt.dockerproject.org/repo ubuntu-xenial main'
sudo apt-get update
apt-cache policy docker-engine
sudo apt-get install -y docker-engine
sudo systemctl status docker  # test:  shoud be ‘active’

And add your user to docker group (to avoid sudo before using docker command in future):

sudo usermod -aG docker $(whoami)

and logout and login again.

Build image

Because node.js is big memory consumer you need 1-2GB RAM or virtual memory to build docker image (it was successfully tested on machine with 512MB RAM + 2GB virtual memory - building process take 7min)

Go to main project folder. To build big (~280MB) image which has cached data and is able to FAST rebuild
(this is good for testing or staging environment) type:

docker build -t angular-starter .

To build SMALL (~20MB) image without cache (so each rebuild will take the same amount of time as first build) (this is good for production environment) type:

docker build --squash="true" -t angular-starter .

The angular-starter name used in above commands is only example image name. To remove intermediate images created by docker on build process, type:

docker rmi -f $(docker images -f "dangling=true" -q)

Run image

To run created docker image on localhost:8080 type (parameter -p 8080:80 is host:container port mapping)

docker run --name angular-starter -p 8080:80 angular-starter &

And that's all, you can open browser and go to localhost:8080.

Run image on sub-domain

If you want to run image as virtual-host on sub-domain you must setup proxy . You should install proxy and set sub-domain in this way:

docker pull jwilder/nginx-proxy:alpine
docker run -d -p 80:80 --name nginx-proxy -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy:alpine

And in your /etc/hosts file (linux) add line: 127.0.0.1 angular-starter.your-domain.com or in yor hosting add folowing DNS record (wildchar * is handy because when you add new sub-domain in future, you don't need to touch/add any DNS record)

Type: CNAME
Hostname: *.your-domain.com
Direct to: your-domain.com
TTL(sec): 43200

And now you are ready to run image on subdomain by:

docker run -e VIRTUAL_HOST=angular-starter.your-domain.com --name angular-starter angular-starter &

Login into docker container

docker exec -t -i angular-starter /bin/bash
