Angular Error Handler

A centralize generic error handler for promises in Angular.

Getting Started

1. Go to your project directory using your command line tool then install the project using npm.

npm install angular-error-handler

2. Include angular.js and angular-error-handler.js to your index page.

<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="angular-error-handler.js"></script>

3. Add the ngErrorHandler module to you application.

angular.module('myApp', ['ngErrorHandler']);

4. You can now use the 'errorHandlerProvider' to automatically handle the errors of your services.

angular.module('myApp').config(function ($provide, errorHandlerProvider) {
  errorHandlerProvider.handle($provide, ['myService', 'myAnotherService']);
});

5. You can also set specific functions that you want to manually handle the error.

angular.module('myApp').config(function ($provide, errorHandlerProvider) {
  errorHandlerProvider.handle($provide, {
    'myService': ['dontHandleErrorsInThisFunction', 'thisFunctionToo'],
    'myAnotherService': ['meToo']
  });
});

6. By default, logging is enabled in errorHandler, you can disable it using the code below.

angular.module('myApp').config(function (errorHandlerProvider) {
  errorHandlerProvider.debugEnabled(false);
});

How to use

A simple usage would be is to listen to errors using the errorNotifier service. Every service functions that is automatically handled by ngErrorHandler that caused errors will appear here. So it's up to you to do anything that you want with the error.

angular.module('myApp').run(function (errorNotifier) {
  errorNotifier.on(function (error) {
    // Do something with the error
  });
});
