* // for the purpose of this example let's assume that variables `$q` and `scope` are * // available in the current lexical scope (they could have been injected or passed in). * * function asyncGreet(name) { * var deferred = $q.defer(); * * setTimeout(function() { * // since this fn executes async in a future turn of the event loop, we need to wrap * // our code into an $apply call so that the model changes are properly observed. * scope.$apply(function() { * if (okToGreet(name)) { * deferred.resolve('Hello, ' + name + '!'); * } else { * deferred.reject('Greeting ' + name + ' is not allowed.'); * } * }); * }, 1000); * * return deferred.promise; * } * * var promise = asyncGreet('Robin Hood'); * promise.then(function(greeting) { * alert('Success: ' + greeting); * }, function(reason) { * alert('Failed: ' + reason); * }); ** * At first it might not be obvious why this extra complexity is worth the trouble. The payoff * comes in the way of * [guarantees that promise and deferred APIs make](https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md). * * Additionally the promise api allows for composition that is very hard to do with the * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the * section on serial or parallel joining of promises. * * * # The Deferred API * * A new instance of deferred is constructed by calling `$q.defer()`. * * The purpose of the deferred object is to expose the associated Promise instance as well as APIs * that can be used for signaling the successful or unsuccessful completion of the task. * * **Methods** * * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection * constructed via `$q.reject`, the promise will be rejected instead. * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to * resolving it with a rejection constructed via `$q.reject`. * * **Properties** * * - promise – `{Promise}` – promise object associated with this deferred. * * * # The Promise API * * A new promise instance is created when a deferred instance is created and can be retrieved by * calling `deferred.promise`. * * The purpose of the promise object is to allow for interested parties to get access to the result * of the deferred task when it completes. * * **Methods** * * - `then(successCallback, errorCallback)` – regardless of when the promise was or will be resolved * or rejected calls one of the success or error callbacks asynchronously as soon as the result * is available. The callbacks are called with a single argument the result or rejection reason. * * This method *returns a new promise* which is resolved or rejected via the return value of the * `successCallback` or `errorCallback`. * * * # Chaining promises * * Because calling `then` api of a promise returns a new derived promise, it is easily possible * to create a chain of promises: * *
* promiseB = promiseA.then(function(result) { * return result + 1; * }); * * // promiseB will be resolved immediately after promiseA is resolved and its value will be * // the result of promiseA incremented by 1 ** * It is possible to create chains of any length and since a promise can be resolved with another * promise (which will defer its resolution further), it is possible to pause/defer resolution of * the promises at any point in the chain. This makes it possible to implement powerful apis like * $http's response interceptors. * * * # Differences between Kris Kowal's Q and $q * * There are three main differences: * * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation * mechanism in angular, which means faster propagation of resolution or rejection into your * models and avoiding unnecessary browser repaints, which would result in flickering UI. * - $q promises are recognized by the templating engine in angular, which means that in templates * you can treat promises attached to a scope as if they were the resulting values. * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains * all the important functionality needed for common async tasks. * * # Testing * *
