What are the best practices for implementing route guards in a routing library?

When implementing route guards, consider the following best practices: 1. Keep guards simple and focused. 2. Use asynchronous checks for authentication. 3. Provide user feedback during navigation. 4. Ensure guards are reusable across routes.

Can you explain how to handle asynchronous checks in route guards?

Certainly! For asynchronous checks, you can return a Promise in your route guard. This allows you to wait for the result of an API call or any other asynchronous operation before allowing or denying access to the route.

What kind of user feedback should I provide during navigation?

User feedback can include loading indicators, messages indicating that access is being verified, or even error messages if access is denied. This helps improve the user experience by keeping them informed.

Are there any common pitfalls to avoid with route guards?

Yes, common pitfalls include over-complicating guards, not handling errors properly, and failing to test the guards thoroughly. Keeping them straightforward and well-documented can help avoid these issues.
