If this value is also a + promise, then the original promise's settled state will match the value's + settled state. So a promise that *resolves* a promise that rejects will + itself reject, and a promise that *resolves* a promise that fulfills will + itself fulfill. + + + Basic Usage: + ------------ + + ```js + let promise = new Promise(function(resolve, reject) { + // on success + resolve(value); + + // on failure + reject(reason); + }); + + promise.then(function(value) { + // on fulfillment + }, function(reason) { + // on rejection + }); + ``` + + Advanced Usage: + --------------- + + Promises shine when abstracting away asynchronous interactions such as + `XMLHttpRequest`s. + + ```js + function getJSON(url) { + return new Promise(function(resolve, reject){ + let xhr = new XMLHttpRequest(); + + xhr.open('GET', url); + xhr.onreadystatechange = handler; + xhr.responseType = 'json'; + xhr.setRequestHeader('Accept', 'application/json'); + xhr.send(); + + function handler() { + if (this.readyState === this.DONE) { + if (this.status === 200) { + resolve(this.response); + } else { + reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); + } + } + }; + }); + } + + getJSON('/posts.json').then(function(json) { + // on fulfillment + }, function(reason) { + // on rejection + }); + ``` + + Unlike callbacks, promises are great composable primitives. + + ```js + Promise.all([ + getJSON('/posts'), + getJSON('/comments') + ]).then(function(values){ + values[0] // => postsJSON + values[1] // => commentsJSON + + return values; + }); + ``` + + @class Promise + @param {function} resolver + Useful for tooling. + @constructor +*/ +function Promise(resolver) { + this[PROMISE_ID] = nextId(); + this._result = this._state = undefined; + this._subscribers = []; + + if (noop !== resolver) { + typeof resolver !== 'function' && needsResolver(); + this instanceof Promise ? initializePromise(this, resolver) : needsNew(); + } +} + +Promise.all = all; +Promise.race = race; +Promise.resolve = resolve; +Promise.reject = reject; +Promise._setScheduler = setScheduler; +Promise._setAsap = setAsap; +Promise._asap = asap; + +Promise.prototype = { + constructor: Promise, + + /** + The primary way of interacting with a promise is through its `then` method, + which registers callbacks to receive either a promise's eventual value or the + reason why the promise cannot be fulfilled. + + ```js + findUser().then(function(user){ + // user is available + }, function(reason){ + // user is unavailable, and you are given the reason why + }); + ``` + + Chaining + -------- + + The return value of `then` is itself a promise. This second, 'downstream' + promise is resolved with the return value of the first promise's fulfillment + or rejection handler, or rejected if the handler throws an exception. + + ```js + findUser().then(function (user) { + return user.name; + }, function (reason) { + return 'default name'; + }).then(function (userName) { + // If `findUser` fulfilled, `userName` will be the user's name, otherwise it + // will be `'default name'` + }); + + findUser().then(function (user) { + throw new Error('Found user, but still unhappy'); + }, function (reason) { + throw new Error('`findUser` rejected and we're unhappy'); + }).then(function (value) { + // never reached + }, function (reason) { + // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. + // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'. + }); + ``` + If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. + + ```js + findUser().then(function (user) { + throw new PedagogicalException('Upstream error'); + }).then(function (value) { + // never reached + }).then(function (value) { + // never reached + }, function (reason) { + // The `PedgagocialException` is propagated all the way down to here + }); + ``` + + Assimilation + ------------ + + Sometimes the value you want to propagate to a downstream promise can only be + retrieved asynchronously. This can be achieved by returning a promise in the + fulfillment or rejection handler. The downstream promise will then be pending + until the returned promise is settled. This is called *assimilation*. + + ```js + findUser().then(function (user) { + return findCommentsByAuthor(user); + }).then(function (comments) { + // The user's comments are now available + }); + ``` + + If the assimliated promise rejects, then the downstream promise will also reject. + + ```js + findUser().then(function (user) { + return findCommentsByAuthor(user); + }).then(function (comments) { + // If `findCommentsByAuthor` fulfills, we'll have the value here + }, function (reason) { + // If `findCommentsByAuthor` rejects, we'll have the reason here + }); + ``` + + Simple Example + -------------- + + Synchronous Example + + ```javascript + let result; + + try { + result = findResult(); + // success + } catch(reason) { + // failure + } + ``` + + Errback Example + + ```js + findResult(function(result, err){ + if (err) { + // failure + } else { + // success + } + }); + ``` + + Promise Example; + + ```javascript + findResult().then(function(result){ + // success + }, function(reason){ + // failure + }); + ``` + + Advanced Example + -------------- + + Synchronous Example + + ```javascript + let author, books; + + try { + author = findAuthor(); + books = findBooksByAuthor(author); + // success + } catch(reason) { + // failure + } + ``` + + Errback Example + + ```js + + function foundBooks(books) { + + } + + function failure(reason) { + + } + + findAuthor(function(author, err){ + if (err) { + failure(err); + // failure + } else { + try { + findBoooksByAuthor(author, function(books, err) { + if (err) { + failure(err); + } else { + try { + foundBooks(books); + } catch(reason) { + failure(reason); + } + } + }); + } catch(error) { + failure(err); + } + // success + } + }); + ``` + + Promise Example; + + ```javascript + findAuthor(). + then(findBooksByAuthor). + then(function(books){ + // found books + }).catch(function(reason){ + // something went wrong + }); + ``` + + @method then + @param {Function} onFulfilled + @param {Function} onRejected + Useful for tooling. + @return {Promise} + */ + then: then, + + /** + `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same + as the catch block of a try/catch statement. + + ```js + function findAuthor(){ + throw new Error('couldn't find that author'); + } + + // synchronous + try { + findAuthor(); + } catch(reason) { + // something went wrong + } + + // async with promises + findAuthor().catch(function(reason){ + // something went wrong + }); + ``` + + @method catch + @param {Function} onRejection + Useful for tooling. + @return {Promise} + */ + 'catch': function _catch(onRejection) { + return this.then(null, onRejection); + } +}; + +function polyfill() { + var local = undefined; + + if (typeof global !== 'undefined') { + local = global; + } else if (typeof self !== 'undefined') { + local = self; + } else { + try { + local = Function('return this')(); + } catch (e) { + throw new Error('polyfill failed because global object is unavailable in this environment'); + } + } + + var P = local.Promise; + + if (P) { + var promiseToString = null; + try { + promiseToString = Object.prototype.toString.call(P.resolve()); + } catch (e) { + // silently ignored + } + + if (promiseToString === '[object Promise]' && !P.cast) { + return; + } + } + + local.Promise = Promise; +} + +polyfill(); +// Strange compat.. +Promise.polyfill = polyfill; +Promise.Promise = Promise; + +return Promise; + +}))); + +}).call(this,require('_process'),typeof global !== "undefined" ? global : typeof self !== "undefined" ? self : typeof window !== "undefined" ? window : {}) +},{"_process":15}],12:[function(require,module,exports){ +// Copyright Joyent, Inc. and other Node contributors. +// +// Permission is hereby granted, free of charge, to any person obtaining a +// copy of this software and associated documentation files (the +// "Software"), to deal in the Software without restriction, including +// without limitation the rights to use, copy, modify, merge, publish, +// distribute, sublicense, and/or sell copies of the Software, and to permit +// persons to whom the Software is furnished to do so, subject to the +// following conditions: +// +// The above copyright notice and this permission notice shall be included +// in all copies or substantial portions of the Software. +// +// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS +// OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +// MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
