An example of an AI chatbot conversation about error handling in Angular CLI with interceptors.
How can I handle errors in Angular CLI using interceptors?
You can handle errors in Angular by creating an HTTP interceptor. This interceptor can catch HTTP errors globally.
Can you show me a basic example of an HTTP interceptor?
Sure! First, create a new interceptor using Angular CLI: ng generate interceptor error. Then, implement the intercept method to handle errors.
What should I do inside the intercept method?
Inside the intercept method, you can use catchError from RxJS to handle errors and return a user-friendly message.
How do I register the interceptor in my app?
You need to provide the interceptor in your app module. Add it to the providers array in app.module.ts.
