What are the best practices for sanitizing data in Angular?

In Angular, it's crucial to sanitize data to prevent security vulnerabilities. Best practices include using Angular's built-in sanitization functions, such as DomSanitizer, to clean HTML, URLs, and styles before binding them to the DOM.

Can you explain how DomSanitizer works?

DomSanitizer is a service in Angular that helps you sanitize potentially dangerous values. It provides methods like bypassSecurityTrustHtml, bypassSecurityTrustUrl, and others to ensure that the data is safe to use in the application.

What should I avoid when sanitizing data?

Avoid using bypassSecurityTrust methods without understanding the risks, as they can expose your application to XSS attacks. Always prefer Angular's built-in sanitization.

Are there any tools to help with sanitization?

Yes, tools like ESLint with security plugins can help identify potential security issues in your code, including improper sanitization practices.
