Angular Web Framework Angular Industry Standards 5 — Questions and Answers
Question 1: What is the Angular community standard for structuring a large-scale application's folder hierarchy?
- Flat structure with all files in src/app
- Feature-based folder structure with core, shared, and feature modules (Correct answer)
- One folder per developer
- Group by file type (all components together, all services together)
Correct answer: Feature-based folder structure with core, shared, and feature modules
Feature-based organization with core (singletons), shared (reusables), and feature modules aligns with the Angular style guide for scalability.
Question 2: Which Semantic Versioning (SemVer) policy does Angular follow for its release cycle?
- Random versioning
- Major version every 6 months, with LTS support for 18 months after release (Correct answer)
- Patch releases only
- One release per year
Correct answer: Major version every 6 months, with LTS support for 18 months after release
Angular follows a predictable 6-month major release cadence with 18 months of LTS, giving enterprises a stable upgrade path.
Question 3: What is the recommended Angular approach for preventing broken links during single-page app navigation?
- Use HashLocationStrategy in all cases
- Use PathLocationStrategy with server-side fallback returning index.html for unknown routes (Correct answer)
- Disable Angular Router and use href links
- Cache all routes in localStorage
Correct answer: Use PathLocationStrategy with server-side fallback returning index.html for unknown routes
PathLocationStrategy produces clean URLs, but requires the server to return index.html for all non-asset routes to prevent 404s on direct navigation.
Question 4: What is the Angular standard for server-side rendering (SSR) to improve SEO and initial load performance?
- Manually duplicate templates for the server
- Use Angular Universal (@angular/ssr) to render the app on the server (Correct answer)
- Use a CDN for SSR
- Pre-render only the homepage
Correct answer: Use Angular Universal (@angular/ssr) to render the app on the server
Angular Universal (now @angular/ssr) is the official Angular solution for server-side rendering, improving SEO and perceived performance.
Question 5: What Angular feature was introduced to modernize component authoring and reduce boilerplate in recent versions?
- NgModule-only components
- Standalone components (no NgModule required) (Correct answer)
- Global component registration
- Template-only components
Correct answer: Standalone components (no NgModule required)
Standalone components, introduced in Angular 14 and stable in Angular 15+, allow components to declare their own imports without NgModule.
Question 6: What is the industry standard for tracking and enforcing Angular bundle size budgets in CI?
- Manually check bundle sizes before each release
- Configure budgets in angular.json to fail the build when thresholds are exceeded (Correct answer)
- Use a browser extension to check size
- Ignore bundle size until performance degrades
Correct answer: Configure budgets in angular.json to fail the build when thresholds are exceeded
The budgets property in angular.json lets teams set warning and error thresholds for bundle sizes, enforced automatically during builds.
Question 7: Which practice is considered the Angular standard for avoiding circular dependency issues in large codebases?
- Import everything from AppModule
- Use barrel files (index.ts) carefully and enforce module boundaries with tools like Nx (Correct answer)
- Allow circular imports and let TypeScript resolve them
- Only use default exports
Correct answer: Use barrel files (index.ts) carefully and enforce module boundaries with tools like Nx
Proper barrel file usage combined with Nx module boundary lint rules prevents circular dependencies that cause runtime errors and slow builds.
