<element attribute="value">{{ expression }}</element>

Example

<!DOCTYPE html>
<html>
<head>
    <title>Angular Template Syntax Example</title>
</head>
<body>
    <!-- Displaying a variable value in a template -->
    <p>Hello {{ name }}</p>

    <!-- Using binding to display a property value -->
    <img [src]="imageUrl" alt="Angular logo">

    <!-- Using structural directives -->
    <ul>
        <li *ngFor="let item of items">{{ item }}</li>
    </ul>
</body>
</html>

Explanation

Angular template syntax follows standard HTML syntax with additional directives, interpolation expressions, and binding expressions to extend its functionality.

  • Interpolation: It allows you to display the value of a component's property in a template by using double curly braces syntax (e.g. {{ name }}).
  • Property Binding: It allows you to set or change the value of an element's property by using square brackets (e.g. [src]="imageUrl").
  • Event Binding: It allows you to bind an event to an element using parentheses (e.g. (click)="onButtonClick()").
  • Two-way Binding: It allows you to bind a property to both the template and the component to keep them in sync. It is done by using the [(ngModel)] directive.
  • Structural Directives: They allow you to conditionally render elements based on a condition and loop through a collection of items. They are used with an asterisk (e.g. *ngIf="showMessage")

Use

Angular template syntax is used to create dynamic views and enhance the functionality of an application. It allows you to display data from a component and interact with the user by responding to events and changes.

Important Points

  • Angular template syntax uses HTML syntax with additional directives and expressions.
  • Interpolation allows you to display the value of a component's property in a template.
  • Binding allows you to set or change the value of an element's property.
  • Structural directives allow you to render elements conditionally and loop through a collection of items.
  • Angular template syntax is used to create dynamic and interactive views.

Summary

Angular Template Syntax is a powerful tool that extends standard HTML syntax to create dynamic and interactive views in Angular applications. Understanding the basic syntax and use cases for interpolation, binding, and structural directives is essential for building applications efficiently and effectively. By using these concepts, you can create customized views, and enhance the user experience.
