angular-async-hooks

This module aims to provide a placeholder for arbitrary code from other modules to process tasks at given points of code, either in series or in parallel.

For example, consider cases where module B requires module A. If you want module B to perform a series of async tasks at a certain point in module A's code, you may find it difficult to use the event trigger / listener system.

With Async Hooks, you can setup a placeholder for such tasks:

someService.validateLogin().then(asyncHooks.then('preLogin')).then(function() {
  someService.doLogin();
});

Here we've provided a placeholder for arbitrary async tasks to complete with the event name preLogin. Your external modules would setup listeners which return a Promise.

// module B
asyncHooks.on('preLogin', function() {

  var deferred = $q.defer();
  console.log("series A called");

  $timeout(function() {
    console.log("series A resolved");
    deferred.resolve();
  }, 1000);

  return deferred.promise;

}, false);
