What are the best practices for implementing router guards in my application?

When implementing router guards, consider the following best practices: 1. Use route-level guards for specific routes. 2. Keep guard logic simple and focused. 3. Handle asynchronous operations gracefully. 4. Provide user feedback during navigation. 5. Test your guards thoroughly.

Can you explain how to handle asynchronous operations in router guards?

Certainly! To handle asynchronous operations in router guards, you can return a Promise or use async/await syntax. This allows you to wait for operations like API calls or authentication checks before allowing navigation.

What kind of user feedback should I provide during navigation?

You can show a loading spinner or a message indicating that the application is processing the request. This helps users understand that their action is being processed.

Are there any common mistakes to avoid with router guards?

Yes, common mistakes include overcomplicating guard logic, not handling errors properly, and failing to test edge cases. Keeping guards simple and clear is key.
