Why Use Angular Material for UI Development?

Angular Material stands out as a UI library due to its alignment with Material Design, a design system developed by Google that emphasizes clean layouts, intuitive interactions, and responsive behavior. Here’s why Angular Material is ideal for Angular UI development:

  • Rich Component Library: Angular Material offers a wide range of components, from basic elements like buttons and inputs to complex ones like data tables and tree structures, reducing custom development time.
  • Material Design Principles: Components adhere to Material Design’s guidelines, ensuring a consistent and visually appealing user experience with smooth animations and clear visual hierarchy.
  • Accessibility Built-In: Components are designed with ARIA (Accessible Rich Internet Applications) support, making your application usable for people with disabilities.
  • Responsive Design: Components adapt to different screen sizes, simplifying the creation of mobile-friendly interfaces.
  • Customizable Theming: Angular Material’s theming system allows you to tailor components to match your brand’s design system.
  • Angular Integration: Built specifically for Angular, it leverages Angular’s dependency injection, modules, and reactive forms for seamless integration.

For instance, using Angular Material’s dialog component, you can create a modal for user confirmation in minutes, complete with animations and accessibility features. To enhance accessibility further, explore this guide on implementing accessibility in Angular.

Getting Started with Angular Material Components

Angular Material’s modular architecture allows you to import only the components you need, keeping your application lightweight. Below, we’ll explore some of the most commonly used components and how to implement them in your Angular application. Each component is imported as a separate NgModule, ensuring optimal performance.

Buttons and Icons

Buttons are fundamental to user interaction, and Angular Material provides a variety of button styles through the <mat-button></mat-button> directive. These include raised, flat, stroked, and icon buttons, each suited for different contexts. Here’s how to use them:

Primary Button
Flat Button
Stroked Button

  favorite

To use buttons and icons, import MatButtonModule and MatIconModule in your module:

import { NgModule } from '@angular/core';
import { MatButtonModule } from '@angular/material/button';
import { MatIconModule } from '@angular/material/icon';

@NgModule({
  imports: [MatButtonModule, MatIconModule],
})
export class AppModule {}

The color attribute (e.g., primary, accent, warn) maps to your theme’s color palette. You can enhance buttons with icons from external libraries like Font Awesome for additional flexibility. Learn how in this guide on adding Font Awesome to Angular.

Buttons are ideal for actions like form submissions or navigation triggers. The <mat-icon</mat-icon> component supports Material Icons by default but can also integrate custom icon sets.

Cards for Content Organization

The <mat-card></mat-card> component is perfect for organizing content into visually distinct sections, such as product listings or user profiles. Here’s an example:

Wireless Headphones
    $99.99
  
  
  
    High-quality sound with noise cancellation.
  
  
    Add to Cart
    View Details

Import MatCardModule:

import { MatCardModule } from '@angular/material/card';

@NgModule({
  imports: [MatCardModule],
})
export class AppModule {}

Style the card in your component’s CSS:

.product-card {
  max-width: 300px;
  margin: 16px;
}

Cards are versatile for e-commerce, blogs, or dashboards, providing a clean way to present structured content. The <mat-card-image</mat-card-image> directive ensures images scale appropriately within the card.

Forms and Inputs

Angular Material’s form components, such as <mat-form-field></mat-form-field>, enhance user input experiences with features like floating labels and validation feedback. Here’s an example of a reactive form:

Name
    
    
      Name is required
    
  
  
    Email
    
    
      Email is required
    
  
  
    Submit

In your component:

import { Component } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';

@Component({
  selector: 'app-user-form',
  templateUrl: './user-form.component.html',
})
export class UserFormComponent {
  userForm: FormGroup;

  constructor(private fb: FormBuilder) {
    this.userForm = this.fb.group({
      name: ['', Validators.required],
      email: ['', [Validators.required, Validators.email]],
    });
  }

  onSubmit() {
    if (this.userForm.valid) {
      console.log(this.userForm.value);
    }
  }
}

Import MatFormFieldModule, MatInputModule, and ReactiveFormsModule:

import { NgModule } from '@angular/core';
import { ReactiveFormsModule } from '@angular/forms';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatInputModule } from '@angular/material/input';

@NgModule({
  imports: [ReactiveFormsModule, MatFormFieldModule, MatInputModule],
})
export class AppModule {}

This setup creates a validated form with error messages, ideal for user registration or settings pages. For advanced form techniques, see this guide on creating custom form validators.

Data Tables for Complex Data

The <mat-table></mat-table> component is designed for displaying tabular data with features like sorting, pagination, and filtering. Here’s an example:

ID
    { { user.id }}
  
  
    Name
    { { user.name }}

In your component:

import { Component, ViewChild } from '@angular/core';
import { MatTableDataSource } from '@angular/material/table';
import { MatSort } from '@angular/material/sort';
import { MatPaginator } from '@angular/material/paginator';

@Component({
  selector: 'app-user-table',
  templateUrl: './user-table.component.html',
})
export class UserTableComponent {
  displayedColumns: string[] = ['id', 'name'];
  dataSource = new MatTableDataSource([
    { id: 1, name: 'Alice' },
    { id: 2, name: 'Bob' },
  ]);

  @ViewChild(MatSort) sort: MatSort;
  @ViewChild(MatPaginator) paginator: MatPaginator;

  ngAfterViewInit() {
    this.dataSource.sort = this.sort;
    this.dataSource.paginator = this.paginator;
  }
}

Import MatTableModule, MatSortModule, and MatPaginatorModule:

import { MatTableModule } from '@angular/material/table';
import { MatSortModule } from '@angular/material/sort';
import { MatPaginatorModule } from '@angular/material/paginator';

@NgModule({
  imports: [MatTableModule, MatSortModule, MatPaginatorModule],
})
export class AppModule {}

This creates a sortable, paginated table, perfect for user management or inventory systems. For dynamic data, fetch records using Angular’s HttpClient, as described in this guide on fetching data with HttpClient.

Customizing Angular Material for Your UI

Angular Material’s flexibility allows you to tailor components to your application’s design while maintaining Material Design’s core principles.

Theming Your Application

Angular Material’s theming system lets you define custom color palettes and typography. Create a custom theme in a SCSS file (e.g., custom-theme.scss):

@use '@angular/material' as mat;

$my-primary: mat.define-palette(mat.$deep-purple-palette);
$my-accent: mat.define-palette(mat.$amber-palette);
$my-warn: mat.define-palette(mat.$red-palette);

$my-theme: mat.define-light-theme((
  color: (
    primary: $my-primary,
    accent: $my-accent,
    warn: $my-warn,
  ),
  typography: mat.define-typography-config(),
));

@include mat.all-component-themes($my-theme);

Include the theme in styles.scss:

@import 'custom-theme';

For dynamic theming, such as toggling dark mode, apply conditional classes:

@Component({
  selector: 'app-theme-toggle',
  template: `Toggle Dark Mode`,
})
export class ThemeToggleComponent {
  isDarkMode = false;

  constructor(private renderer: Renderer2) {}

  toggleDarkMode() {
    this.isDarkMode = !this.isDarkMode;
    const themeClass = this.isDarkMode ? 'dark-theme' : '';
    this.renderer.setAttribute(document.body, 'class', themeClass);
  }
}

Define the dark theme in custom-theme.scss:

.dark-theme {
  $dark-theme: mat.define-dark-theme((
    color: (
      primary: $my-primary,
      accent: $my-accent,
      warn: $my-warn,
    ),
  ));
  @include mat.all-component-themes($dark-theme);
}

Explore dark mode further in this guide on implementing dark mode in Angular.

Styling Components

Customize component styles using CSS. For example, adjust the appearance of a card:

.mat-card {
  border-radius: 8px;
  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
  margin: 16px;
}

To target specific components, use Angular’s component styles or ::ng-deep cautiously for global overrides. Avoid overusing ::ng-deep to maintain encapsulation.

Adding Animations

Angular Material components include built-in animations (e.g., dialog transitions), but you can enhance them using Angular’s animation API. For example, animate a button on hover:

import { Component } from '@angular/core';
import { trigger, state, style, animate, transition } from '@angular/animations';

@Component({
  selector: 'app-animated-button',
  template: `
    
      Hover Me
    
  `,
  animations: [
    trigger('hoverState', [
      state('normal', style({ transform: 'scale(1)' })),
      state('hovered', style({ transform: 'scale(1.05)' })),
      transition('normal <=> hovered', animate('200ms ease-in-out')),
    ]),
  ],
})
export class AnimatedButtonComponent {
  state = 'normal';
}

Learn more about animations in this guide on creating animations in Angular.

Advanced Use Cases

Building Responsive Layouts

Angular Material’s layout directives, provided by the Angular CDK, simplify responsive design. Use the BreakpointObserver to adjust layouts based on screen size:

import { Component } from '@angular/core';
import { BreakpointObserver, Breakpoints } from '@angular/cdk/layout';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';

@Component({
  selector: 'app-responsive-layout',
  template: `
    
      Content adapts to screen size
    
  `,
  styles: [
    `
      .container { padding: 16px; }
      .mobile { flex-direction: column; }
    `,
  ],
})
export class ResponsiveLayoutComponent {
  isMobile$: Observable;

  constructor(breakpointObserver: BreakpointObserver) {
    this.isMobile$ = breakpointObserver.observe(Breakpoints.Handset).pipe(
      map(result => result.matches)
    );
  }
}

Import LayoutModule from @angular/cdk/layout. This approach ensures your UI adapts to desktops, tablets, and mobiles. For more on responsive design, see this guide on creating responsive layouts.

Integrating with Routing

Use Angular Material’s navigation components, like <mat-sidenav></mat-sidenav>, to create responsive menus that integrate with Angular’s router:

Home
      Profile
    
  
  
    
      
        menu
      
      My App

Import MatSidenavModule, MatToolbarModule, MatNavListModule, and RouterModule. This creates a responsive sidebar that works with Angular’s routing system. Learn more in this guide on Angular routing.

Lazy Loading for Performance

To optimize performance, lazy load Material components in feature modules:

@NgModule({
  imports: [
    MatCardModule,
    RouterModule.forChild([
      { path: '', component: FeatureComponent },
    ]),
  ],
})
export class FeatureModule {}

This reduces the initial bundle size. Explore lazy loading in this guide on setting up lazy loading in Angular.

Common Pitfalls and Solutions

  • Missing Styles: If components appear unstyled, ensure the theme is included in styles.scss and referenced in angular.json.
  • Animation Issues: Import BrowserAnimationsModule for animations or NoopAnimationsModule to disable them.
  • Large Bundle Size: Import only necessary Material modules and use lazy loading for feature modules.
  • Accessibility Oversights: Always add ARIA labels and test with screen readers. Refer to this [guide on using ARIA labels](/angular/accessibility/use-aria-labels-in-ui).
