Anybody have an example of how to install a custom exception handler?
I’ve been looking into wiring this up:
https://angular.io/docs/js/latest/api/core/ExceptionHandler-class.html
The example code throws compile errors in my project.

Anyone thoughts on this?
Trying another bump…
Could we add a hook for ExceptionHandler here? Or is there an other to catch all exceptions?
https://github.com/driftyco/ionic/blob/2.0/ionic/config/bootstrap.ts
You can define providers inside the @App annotation:
@App({
providers: [provide(ExceptionHandler, {useClass:MyExceptionHandler})]
})
I did that and it worked, thanks.
Typescript still complains with the override documented [at the link at the top of the page]
(https://angular.io/docs/js/latest/api/core/ExceptionHandler-class.html47), even though it works. One way to make Typescript stop complaining is to use extends
instead of implements
- that worked without typescript type complaints. Define this before class App
in app.ts
:
class MyExceptionHandler extends ExceptionHandler {
call(error, stackTrace = null, reason = null) {
// do something with the exception
}
}
Then add the providers
line in the response above this one to your app class and this should work fine.
However: doing all the above works on catching many exceptions, still, some exceptions do not get caught using this, not sure yet why…
