Angular Material Interview Questions

  1. What is Angular Material?

    • Answer: Angular Material is a UI component library for Angular that implements Google's Material Design. It provides pre-built, reusable components like buttons, cards, forms, navigation, and more, adhering to Material Design guidelines for a consistent and visually appealing user interface.

  2. How does Angular Material differ from other UI libraries like Bootstrap or PrimeNG?

    • Answer: Angular Material is specifically designed for Angular, integrating seamlessly with its framework. Bootstrap and PrimeNG are more general-purpose and require additional effort to integrate fully with Angular. Angular Material also strictly adheres to Material Design guidelines, offering a consistent look and feel across components, unlike the more flexible styling options of Bootstrap or PrimeNG.

  3. Explain the concept of Material Design.

    • Answer: Material Design is a design language developed by Google. It emphasizes clean lines, grid-based layouts, responsive design, and intuitive interactions. It uses visual metaphors inspired by paper and ink to create a visually appealing and user-friendly experience. Key elements include cards, grids, typography, and color palettes.

  4. How do you install Angular Material in an Angular project?

    • Answer: You install Angular Material using the Angular CLI. First, you need to install the necessary packages: `ng add @angular/material`. This command automatically imports the necessary modules and styles into your application.

  5. Describe the different modules in Angular Material.

    • Answer: Angular Material is composed of several modules, each providing a specific set of components. Examples include `MatCardModule`, `MatButtonModule`, `MatFormFieldModule`, `MatInputModule`, `MatToolbarModule`, `MatSidenavModule`, `MatTableModule`, `MatDialogModule`, `MatSnackBarModule`, and many more. Each module needs to be imported individually into your component or app module to use its components.

  6. How do you customize the theme of Angular Material?

    • Answer: Angular Material provides extensive theming capabilities. You can customize colors, typography, and spacing using Sass variables and mixins. You can create your own custom themes or leverage pre-defined themes. The process typically involves creating a custom theme file and importing it into your application's stylesheet.

  7. Explain the use of `@angular/cdk` (Angular CDK).

    • Answer: The Angular CDK (Component Dev Kit) provides foundational building blocks for Angular Material components. It offers directives and services that handle things like accessibility, drag-and-drop, virtual scrolling, and more. Angular Material components are built on top of the CDK, leveraging its features to enhance functionality and performance.

  8. How do you implement responsive design with Angular Material components?

    • Answer: Angular Material components are inherently responsive. You can leverage features like flexbox and media queries within your component's CSS to adjust layouts based on screen size. Many components have built-in responsive features, automatically adapting to different screen sizes.

  9. How to use Angular Material's `MatTable` component?

    • Answer: `MatTable` displays data in a tabular format. You need to define the data source (typically an array of objects), define columns using `MatColumnDef` and `MatHeaderCell`, and then render cells using `MatCell`. You can also implement features like pagination, sorting, and filtering.
