Read the first 7 Angular Industry Standards flashcards as text
What is the recommended Content Security Policy (CSP) practice for Angular applications to prevent XSS?
Answer: Use Angular's built-in sanitization and set strict CSP headers server-side
Angular's DomSanitizer combined with strict server-side CSP headers provides defense-in-depth against XSS attacks.
Which Angular build option is recommended for production deployments to minimize bundle size?
Answer: ng build --configuration=production (enables AOT, tree-shaking, minification)
The production configuration enables Ahead-of-Time compilation, tree-shaking, and minification, all critical for smaller production bundles.
What is the industry-standard approach for internationalizing (i18n) Angular applications for the US market expanding globally?
Answer: Use Angular's built-in i18n with @angular/localize or a library like ngx-translate
Angular's @angular/localize supports compile-time i18n, while ngx-translate offers runtime flexibility — both are widely adopted standards.
What strategy should Angular applications use for API versioning to remain industry-compliant?
Answer: Abstract API URLs behind a configuration layer and use versioned endpoint paths (/v1/, /v2/)
Centralizing versioned API URLs in environment files or a config service allows seamless version upgrades without touching components.
Which pattern is the Angular standard for reactive form validation feedback to users?
Answer: Display error messages using form control's touched/dirty state combined with validation errors
Checking touched or dirty state before showing errors prevents premature validation feedback on untouched fields.
What is the recommended approach for Angular component communication between non-parent-child components?
Answer: Use a shared service with BehaviorSubject or an NgRx store
A shared service with a BehaviorSubject (or NgRx for complex state) provides a clean, reactive channel for sibling or distant component communication.
What is the Angular community-recommended practice for handling authentication tokens in HTTP requests?
Answer: Use an HTTP interceptor to automatically attach Authorization headers
An HTTP interceptor centralizes token attachment, refreshing, and expiry handling without duplicating logic across services or components.
