Implement attribute directives with @Directive, @HostBinding and @HostListener. Use Renderer2, ElementRef and NativeElement to change the appearance and behavior of DOM elements.

Iterate over a TypeScript enum and use the values to populate a dropdown list.

A few examples of how to use *ngFor to repeat an element a specified number of times.

Examples of how to use template reference variables to reference DOM elements, components and directives in a template.

An example of how child routes and nested directives allow navigation between multiple views when a user clicks a link in a sub-menu.

This tutorial builds on a simple router example and assumes that you have read this tutorial first.

Use the Angular router to navigate between components when the user clicks a link. We take a look at routerLink, routerLinkActive, <router-outlet> and more.

See how event bindings listen for DOM events such as click and keypress on standard HTML elements such as button and input.

Bind to the following <input> fields with Angular 2 and TypeScript: text, textarea, checkbox, radio and select (drop-down list).

Interpolation uses template expressions in double curly braces to display data from the component class and template reference variables.

Use template expressions to bind to DOM properties such as hidden and title on standard HTML elements such as div and span.

Combine the square brackets of property binding and the parentheses of event binding to create two-way binding with ngModel.

Angular's templates mix native HTML with custom elements. In this short tutorial we see how to use inline and external templates.

Use property binding and the @Input decorator to pass data into a component, and @Output and EventEmitter to pass data out and bind to an event.

Learn Angular with TypeScript. This tutorial includes examples of components, template syntax, property binding, event binding, bootstrapping and more.

See how Angular uses the ngIf, ngSwitch, ngFor, ngClass and ngStyle directives to transform the DOM when a template is rendered.

The ngIf directive adds and removes elements in the DOM based on the results of an expression.

The ngSwitch directive displays one element (and its children) from a set of possible options, based on some condition.

ngFor is a repeater directive which outputs a list of elements by iterating over an array.

ngClass adds and removes CSS classes on an element. An [ngClass] directive (in square brackets) uses the results of a template expression (in quotes) to set the names of the classes.

The ngStyle directive allows you to set CSS styles on an HTML element conditionally.

Content projection is a way to import HTML content from outside the component and insert that content into the component's template in a designated spot.

A quick start example for beginners who are new to Angular and TypeScript. This tutorial shows how to implement a super-simple custom element using an Angular component.
