Angular Universal uses a technique known as _____ to handle asynchronous tasks on the server side.
- Client-Side Rendering
- Server-Side Rendering
- Service Workers
- Universal Injection
Angular Universal employs a technique known as Server-Side Rendering (SSR) to handle asynchronous tasks on the server side.
When you want to preload data for a route, you can use the _____ property in the route configuration.
- canActivate
- data
- loadChildren
- resolve
To preload data for a route, you can use the resolve property in the route configuration. The 'resolve' property allows you to fetch data before activating the route.
Why might you use a Subscription in an Angular application?
- To create Observables
- To define component behavior
- To make HTTP requests
- To manage memory leaks
You would use a Subscription in an Angular application to manage memory leaks by unsubscribing from Observables when they are no longer needed. This helps prevent memory consumption issues.
The Angular CLI command to analyze your application's source code and extract canonical information is ngAnalyze.
- ngAnalyze
- ngAnnotate
- ngExtract
- ngInspect
The ngAnalyze command in Angular CLI is used to analyze the application's source code and extract canonical information for further use.
How does the Ivy Renderer's instruction set contribute to improved performance in Angular applications?
- Enables Ahead-of-Time (AOT) compilation
- Minimizes network requests
- Optimizes the rendering process
- Reduces JavaScript bundle size
The Ivy Renderer's instruction set in Angular contributes to improved performance by optimizing the rendering process, resulting in faster component rendering.
What is the primary purpose of End-to-End (E2E) testing in an Angular application?
- Test Angular services
- Test individual components
- Test server-side logic
- Test the user interface
The primary purpose of E2E testing in an Angular application is to test the user interface to ensure that all parts of the application work together as expected.
How can you share a single Observable execution between multiple subscribers?
- Using the filter() operator
- Using the map() operator
- Using the mergeMap() operator
- Using the share() operator
You can share a single Observable execution between multiple subscribers by using the share() operator. This allows multiple subscribers to share the same execution and results of the Observable.
Which file in an Angular component contains metadata and helps Angular understand how to process a class?
- app.component.ts
- app.module.ts
- index.html
- styles.css
In Angular, the file that contains metadata and helps Angular understand how to process a class is app.component.ts.
You've noticed that a specific component in your application is being checked and re-rendered by Angular even though its input data hasn't changed. You want to optimize it so that Angular only re-renders it when the input data actually changes. What would you implement?
- Change Detection Strategy
- Dependency Injection
- Pure Pipe
- ngOnChanges Lifecycle Hook
To optimize re-rendering, you should implement a Change Detection Strategy, such as OnPush, to make Angular re-render the component only when its input data changes.
What is the purpose of using the resolve property in Angular routing?
- Define route aliases
- Load data before activating
- Preload lazy-loaded modules
- Redirect to a default route
The purpose of using the resolve property in Angular routing is to load data before activating a route, ensuring that data is available for the component.
