Try out Angular 2 Step by Step

Angular 2 Practise Step By Step

##Overview This is a very simple application to demonstrate the capabilities of Angular 2. It is not a tutorial but rather a teaching tool to help me introduce Angular 2 to programmers without prior exposure to Angular 2. This repo contains the code completed during hands-on programming sessions. Each session is meant to be an 1 to 1.5 hours long with one session per day. So this repo is more of a reference for me and anyone that attended the sessions.

##Prerequisites

• Git
• Nodejs 4.x or later
• NPM 3.x.x or later <-- will be installed with nodejs from the above link.
• Angular CLI

##Commits/Tutorial Outline You can check out any point of the tutorial using:

git checkout day-?

##Day 01

Overview

Use git checkout day-01 to get the work done on day 1. This project was generated with angular-cli version 1.0.0-beta.15. This step contains an empty angular2 project generated by angular-cli

Development server

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive/pipe/service/class.

####Employee Component Create an EmployeeComponent using the command ng g c employee.

NOTE: The generated components will always have

• component.css file for component styles
• component.html file for the components template
• component.ts file for the components logic
• component.spec.ts file for the unit tests

####Employee Class Create an Employee class using the command ng g class employee. This represents the Employee Model.

Build

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.

Running unit tests

Run ng test to execute the unit tests via Karma.

Running end-to-end tests

Run ng e2e to execute the end-to-end tests via Protractor. Before running the tests make sure you are serving the app via ng serve.
