Use unobtrusive Toast messages to gently notify users of the success, failure or state of their front-end actions & tasks:

Organize app features into components & modules so they are easier to maintain or re-use.
An example is a footer module which includes a: component (*.ts), stylesheet (*.scss), template (*.html) and a module (*.module.ts)
Routing & Navigation:
Learn More
Dynamically navigate users to views or parts your app depending on sections or parts of the url instead of loading a new page (app.module.ts):
 * RouteModule.forRoot declares a Singleton RouterModule with an array of routes
imports: [
    {path: 'login', component:LoginComponent},
    {path: 'register', component: RegisterComponent}
Routing & Views:
Learn More
Dynamically load parts of your app based on the url using the < router-outlet > directive and display clickable navigation using the directive in your app's root template (app.component.html):
< nav >
  < a routerLink="/login" >Login< /a > |
  < a routerLink="/register" >Register< /a >
< /nav >
< router-outlet >< /router-outlet >
Routing & Security:
Learn More
Guard against un-authorized access to features, pages or views and block any route from loading based on permissions or authentication using a class that implements the CanActivate interface(AuthGuard.ts):
export class AuthGuard implements CanActivate {
  constructor(private _authService: AuthService, private _router: Router) {
  canActivate(next: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable | Promise | boolean {
    if (this._authService.isAuthenticated()) {
        return true;
    // navigate to login page
    return false;
Protect any route using the AuthGuard service (app.module.ts):
imports: [
    {path: 'login', component:LoginComponent},
    {path: 'account', component: AccountComponent, canActivate:[AuthGuard]}
Data-Binding, @Input & @Output:
Learn More
Use @Input decorator to pass data from parent to child and @Output (or observables) to pass data from the child to the parent.
A parent component can bind it's property (e.g. pData) to a child's (e.g. cData) using the child 's @Input() property (@Input() cData: any;):
< page-child [cData] = "pData" > < /page-child >
A child component can pass back it's data to a parent's using the child 's @Output() property and an event emitter:
@Input() cData: any;
@Output() dataChange = new EventEmitter();
changeData() {
    this.dataChange.emit('data has changed);
A parent component can handle or respond to an Output event from the child using an event handler in its class:
< page-child (dataChange) = "handleChildDataChange($event)" > < /page-child >
A cheatsheet can help summarize Angular's template binding: Learn More

Forms allow users to submit input when interacting with an app. They are useful for signing users in, searching, submitting feedback and more.
Angular provides template-driven forms and model-driven or reactive forms.
Template driven forms use built-in directives like ngModel and ngForm to build forms.
A template driven newsletter signup component looks like: Learn More

How To Add Custom Reusable Alerts, Notifications, Messages or Announcements to your Angular Mobile Apps / Websites
Toast messages are gentle messages displayed to alert users of the success, failure or state of user actions.

Do write a reusable toast message in a "utilities provider". Don't code multiple toast messages that provide the same or similar behaviors

How To Add Components or Modules to an Angular / Ionic App

Design repeating UI features in components with a view, class & stylesheet and export the component as a module for reusability across your app

A reusable footer component in an Ionic Angular App is designed as:
  • footer.html - A user interface (UI) file that includes all the HTML presented by the footer
  • footer.ts - A typescript class that represents the view / template's data model and presentational logic
  • footer.module.ts - A typescript class that imports the footer.ts class and re-exports it as a footer module that's reusable across the app
