bbrown / exception-decorator
Created April 21, 2015 19:59
Angular decorator to handle unhandled exceptions, if necessary.
// All unhandled exceptions in an AngularJS application are passed to a service $exceptionHandler,
// which logs the error message in the browser's console. In large business applications, you may want
// to log the error details on the server by calling an API. This can be done by decorating the $exceptionHandler service.
// #49 - http://www.dotnetcurry.com/showarticle.aspx?ID=1115
app.config(function($provide)
{
$provide.decorator('$exceptionHandler', ['$log', '$http', '$delegate', function ($log, $http, $delegate)
{
return function (exception, cause)
