Simple and quick step-by-step tutorial guide for Angular application.

Uses docker (>=17.05) container setup for easy development.

Goal: Create the development docker image

1. create the docker image as configured in the docker-compose.yml

   docker-compose build
   

2. on *nix system, test container can be created correctly

   run_docker.sh
   

Goal: Default angular application using docker

1. start docker container

   run_docker.sh
   

2. quick check the directory location and ensure it is mapped to local development by running this and checkout the output

   /wip# ls -al
   

3. create new application using Angular CLI

   ng new angular --routing true --enableIvy true
   

   select the desired options through the interactive menus
4. update package.json with these scripts for quick DEV commands

   "start:dev": "ng serve --host 0.0.0.0",
   

5. in the container start the Angular application

   /wip/angular# npm run start:dev
   

6. check the application on host browser

   http://localhost:4200/
   

   

Goal: Create simple homepage UI components: [Home, About]

Refactor the default Angular application into frame and home component. Also create a new about component to allow switching between 2 URLs that maps to the 2 components.

1. create a feature module to contain the components

   ng generate module homepage --module app --routing true
   

2. create the components

   ng generate component homepage/home --module homepage
   ng generate component homepage/about --module homepage --style scss
   

3. update the route to show the components ... homepage-routing.module.ts

   const routes: Routes = [
     { path: 'home', component: HomeComponent },
     { path: 'about', component: AboutComponent },
   ];
   

4. test the new path, /home and /about

   http://localhost:4200/home
   http://localhost:4200/about
   

Goal: Use Angular Material components to build visuals

Refactor the Angular application to import Angular Material library and update the layout / components with Material visaul

1. import the Angular Material library

   ng add @angular/material
   

2. choose the menu options these options

   Indigo/Pink theme
   Set up HammerJS for gesture recognition? Yes
   Set up browser animations for Angular Material? Yes
   

3. update app.module.ts with the desired Angular Material components

   import {
       MatToolbarModule,
       MatIconModule,
       MatCardModule,
       MatButtonModule,
       MatProgressSpinnerModule
   } from '@angular/material';
   

4. update app.module.ts imports array for the NgModule declaration

   imports: [
       BrowserModule,
       AppRoutingModule,
       BrowserAnimationsModule,
       MatToolbarModule,
       MatIconModule,
       MatButtonModule,
       MatCardModule,
       MatProgressSpinnerModule
   ],
   

5. update app.component.html with the component elements: toolbar with 2 buttons

   <mat-toolbar color="primary">

       </h1>
       <button mat-button routerLink="/">Home</button>
       <button mat-button routerLink="/about">About</button>
