When ViewEncapsulation.Native is used, the styling is encapsulated using the browser's native ________.
- CSS-in-JS
- Inline styles
- Scoped CSS
- Shadow DOM
When ViewEncapsulation.Native is used, the styling is encapsulated using the browser's native Shadow DOM. Shadow DOM is a web standard that provides encapsulation of styles and markup, ensuring that styles in one component do not affect styles in another. It's a key feature in achieving component-based styling in Angular.
A client asks for a feature where certain parts of the application should only be accessible to authenticated users. Which feature of Angular would you use to implement this?
- Angular Directives
- Data Binding
- Dependency Injection
- Route Guards
In Angular, you can implement access control for certain parts of the application by using Route Guards. Route Guards allow you to protect routes based on conditions, such as whether the user is authenticated. Data Binding, Dependency Injection, and Angular Directives are not specifically designed for access control.
How do you create a link in your template that navigates to a different route in Angular?
- Using the tag with an href attribute.
- Using the router-link directive.
- Using the navigateTo function.
- Using the ng-route module.
In Angular, you create a link in your template that navigates to a different route using the router-link directive. This directive is specifically designed for routing and allows you to define the target route as an attribute. The other options, such as using an tag with href, a navigateTo function, or the ng-route module, are not standard ways to handle routing in Angular and may not work as expected.
Which state management library focuses on simplicity and minimizes boilerplate code?
- Ngxs
- MobX
- Redux
- Vuex
Ngxs is a state management library for Angular that emphasizes simplicity and minimizes boilerplate code. It provides a clean and straightforward way to manage state within Angular applications, making it an attractive option for developers looking for a more straightforward approach to state management.
Your application's end-users have reported intermittent errors. You decide to use source maps to debug the production build of your Angular application. Which of the following considerations is essential when using source maps in production?
- Disable source maps in production for better performance
- Protect the source maps from public access
- Store source maps in the same directory as your production code
- Use unminified code in production
It's crucial to protect source maps from public access in a production environment to prevent exposing sensitive information and source code to potential attackers. Source maps should not be accessible to end-users.
To designate a place in your template where the router should display the components for that route, use the ________ directive.
- ngRoute
- router-view
- ng-display
- route-render
To designate a place in your template where the router should display the components for that route, use the router-view directive. This directive is used in the template to specify where the routed components should be rendered. The other options mentioned, like ngRoute, ng-display, and route-render, are not Angular's standard directives for this purpose.
Which command-line tool is primarily used for initializing and managing Angular projects?
- ng create
- ng init
- ng new
- ng start
The correct command for initializing and managing Angular projects is ng new. It's used to create a new Angular application by setting up the project structure, configuration files, and initial dependencies.
After creating a dynamic component, if you want to access its instance and modify some properties, you can obtain it through the ______ property of the reference.
- instance
- componentRef
- componentInstance
- dynamicComponent
After creating a dynamic component in Angular, if you want to access its instance and modify some properties, you can obtain it through the componentInstance property of the reference (e.g., ComponentRef). This allows you to interact with the dynamically created component and make changes as needed. The other options are not the standard properties for accessing the instance.
What purpose does the redirectTo property serve in Angular's routing configuration?
- It navigates to the route specified when the application starts.
- It redirects to a specific route if the current route is empty.
- It sets up a wildcard route for unmatched routes.
- It specifies the route to be used when an error occurs.
The redirectTo property in Angular's routing configuration serves to redirect to a specific route if the current route is empty. This is often used to define default routes or to ensure that users are directed to a particular route when they access the application's root URL. It helps improve user experience by ensuring they are on a meaningful route.
Which Route Guard is especially useful for feature modules that are lazy-loaded?
- CanActivate
- CanDeactivate
- CanLoad
- CanUnload
The CanLoad Route Guard is especially useful for feature modules that are lazy-loaded. It allows you to prevent the lazy-loaded module from being loaded if certain conditions are not met, such as authentication or authorization checks.
