Create a shared service with a BehaviorSubject to store and emit data
Inject the shared service into both components that need to share data
Subscribe to the BehaviorSubject in each component to receive updates
- Q2. How do we do lazy loading
- Ans.
Lazy loading in Angular allows for loading modules only when they are needed, improving performance.
Lazy loading is achieved by using the loadChildren property in the route configuration.
Modules are loaded asynchronously when the user navigates to a route that requires them.
Lazy loading helps reduce the initial bundle size and improve the app's loading time.
Example: { path: 'admin', loadChildren: () => import('./admin/...
- Q3. How would you take care of XSS vulnerability
- Ans.
Prevent XSS vulnerability by sanitizing user input, using Angular's built-in security features, and implementing Content Security Policy.
Sanitize user input by using Angular's DomSanitizer to prevent execution of malicious scripts
Use Angular's built-in security features like SafeValue and SafeHtml to securely render user input
Implement Content Security Policy (CSP) to restrict the sources from which scripts can be load...
- Q4. How do you take data from more than one service at a time in a component
- Ans.
Use observables and combineLatest operator to fetch data from multiple services in a component
Create observables for each service call
Use combineLatest operator to combine the observables and fetch data from all services at once
Subscribe to the combined observable to get the data
