Angular generic error handler

If things go wrong the request will return a response with an error code. Based on this error code you for example want to. Implement an HttpInterceptor ( requires Angular 4. From there listen to errors and extract the request url and split it into its parts. To intercept error handling, write a custom exception handler that replaces this default as appropriate for your app. class MyErrorHandler implements ErrorHandler { handleError( error) { / / do something with the exception } } @ NgModule( {. Based on a generic Error constructor, Javascript throws an Error each time something goes wrong. By default, Angular comes with its own ErrorHandler that intercepts all the Errors that happen in our app and logs them to. Creating custom ErrorHandler works as global error handler because our custom ErrorHandler will execute for any error thrown from anywhere in the application.

Then in your code inject CustomAuthHttp instead of AuthHTTP and use. Error handling is one of those things no one wants to deal with, well in Angular you can create a global handler and never have to worry again. Angular defines an ErrorHandler class that will allow us to override it and handle. I am using interceptor in my app for generic error handling when service is down I am getting success response with status 200 even i have changed the base url to test my service.
