An example of an AI chatbot conversation about Angular routing guards best practices.
What are the best practices for using routing guards in Angular?
When using routing guards in Angular, it's important to keep your guards focused and reusable. Use CanActivate for route protection and CanDeactivate for unsaved changes.
Can you explain the difference between CanActivate and CanDeactivate?
Sure! CanActivate checks if a route can be activated, while CanDeactivate checks if a user can leave a route, often used to prevent data loss.
How can I implement a guard that checks user roles?
You can create a custom guard by implementing the CanActivate interface and checking the user's role in the canActivate method.
Are there any performance considerations I should be aware of?
Yes, avoid heavy computations in guards. Use observables efficiently and cache results when possible to enhance performance.
