Angular Material & UI Component Libraries
5 questions found
What is Angular Material and why do teams use it?
Beginner
Angular Material is an official component library built by the Angular team, providing ready to use, well tested, and accessible components like buttons, dialogs, and date pickers that follow Google's Material Design guidelines. Using it saves teams from having to build and style common components from scratch.
import { MatButtonModule } from '@angular/material/button';
@Component({
selector: 'app-root',
imports: [MatButtonModule],
template: `<button mat-raised-button color="primary">Click Me</button>`
})
export class AppComponent {}
Real-world example
A startup builds their entire admin dashboard using Angular Material components, getting a polished, consistent, and accessible look without needing to design and build every button and form field from scratch.

How do you add a Material dialog to an Angular app?
Beginner
You inject the MatDialog service into your component, and call its open method with the component you want to display inside the dialog. The dialog handles showing itself, dimming the background, and closing correctly when the user is done.
import { MatDialog } from '@angular/material/dialog';
constructor(private dialog: MatDialog) {}
openConfirmDialog() {
this.dialog.open(ConfirmDialogComponent);
}
Real-world example
A settings page shows a confirmation dialog asking the user to confirm before deleting their account, using Angular Material's MatDialog service to handle the popup behavior correctly.

How would you build a responsive data table using Angular Material's table component?
Intermediate
Angular Material's table component works together with a data source, and you define which columns to display using column definitions in your template, giving you a fully functional, sortable, and accessible table without manually building the table markup and behavior yourself.
<table mat-table [dataSource]="users">
<ng-container matColumnDef="name">
<th mat-header-cell *matHeaderCellDef>Name</th>
<td mat-cell *matCellDef="let user">{{ user.name }}</td>
</ng-container>
<tr mat-header-row *matHeaderRowDef="['name']"></tr>
<tr mat-row *matRowDef="let row; columns: ['name']"></tr>
</table>
Real-world example
An admin panel displays a list of users in a sortable, accessible table using Angular Material's table component, saving significant time compared to building the same table markup by hand.

How do you create a custom form field control that integrates properly with Angular Material's form field wrapper?
Advanced
You implement the MatFormFieldControl interface on your custom component, providing the required properties and methods Angular Material expects, letting your custom input work seamlessly inside a standard mat form field wrapper, complete with labels, hints, and error messages just like a built in input.
@Component({
selector: 'app-custom-input',
providers: [{ provide: MatFormFieldControl, useExisting: CustomInputComponent }]
})
export class CustomInputComponent implements MatFormFieldControl<string> {
// implement required properties like value, stateChanges, and required methods
}
Real-world example
A design system team builds a custom currency input component that fits perfectly inside Angular Material's form field wrapper, automatically getting consistent labels and validation styling that match every other form field in the app.
Common follow-ups: What specific properties and methods does the MatFormFieldControl interface require you to implement?;Why is this more work than just wrapping a plain input inside a mat form field manually?

What other popular Angular UI component libraries exist besides Angular Material?
Beginner
Other widely used options include PrimeNG, which offers a very large collection of components and several visual themes, and Ng Bootstrap, which brings Bootstrap's popular design system into native Angular components without needing jQuery. The right choice usually depends on the specific design style and features a project needs.
// PrimeNG example
import { ButtonModule } from 'primeng/button';
@Component({
imports: [ButtonModule],
template: `<p-button label="Click Me"></p-button>`
})
export class AppComponent {}
Real-world example
A team that already has an existing Bootstrap based design system chooses Ng Bootstrap for their new Angular app, keeping a familiar visual style while still getting properly built native Angular components.
Common follow-ups: What factors should a team consider when choosing between these different component libraries?;Can you mix components from more than one UI library in the same project?
