initializePromise(this, resolver) : needsNew(); - } - } - /** - 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} - */ - /** - `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} - */ - Promise.prototype.catch = function _catch(onRejection) { - return this.then(null, onRejection); - }; - /** - `finally` will be invoked regardless of the promise's fate just as native - try/catch/finally behaves - - Synchronous example: - - ```js - findAuthor() { - if (Math.random() > 0.5) { - throw new Error(); - } - return new Author(); - } - - try { - return findAuthor(); // succeed or fail - } catch(error) { - return findOtherAuther(); - } finally { - // always runs - // doesn't affect the return value - } - ``` - - Asynchronous example: - - ```js - findAuthor().catch(function(reason){ - return findOtherAuther(); - }).finally(function(){ - // author was either found, or not - }); - ``` - - @method finally - @param {Function} callback - @return {Promise} - */ - Promise.prototype.finally = function _finally(callback) { - var promise = this; - var constructor = promise.constructor; - if (isFunction(callback)) { - return promise.then(function (value) { - return constructor.resolve(callback()).then(function () { - return value; - }); - }, function (reason) { - return constructor.resolve(callback()).then(function () { - throw reason; - }); - }); - } - return promise.then(callback, callback); - }; - return Promise; - }(); - Promise$1.prototype.then = then; - Promise$1.all = all; - Promise$1.race = race; - Promise$1.resolve = resolve$1; - Promise$1.reject = reject$1; - Promise$1._setScheduler = setScheduler; - Promise$1._setAsap = setAsap; - Promise$1._asap = asap; - /*global self*/ - function polyfill() { - var local = void 0; - if (typeof __webpack_require__.g !== 'undefined') { - local = __webpack_require__.g; - } - 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$1; - } - // Strange compat.. - Promise$1.polyfill = polyfill; - Promise$1.Promise = Promise$1; - return Promise$1; -}))); - - -/***/ }), - -/***/ "./node_modules/events/events.js": -/*!***************************************!*\ - !*** ./node_modules/events/events.js ***!

The\n primary way of interacting with a promise is through its `then` method, which\n registers callbacks to receive either a promise's eventual value or the reason\n why the promise cannot be fulfilled.\n\n Terminology\n -----------\n\n - `promise` is an object or function with a `then` method whose behavior conforms to this specification.\n - `thenable` is an object or function that defines a `then` method.\n - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).\n - `exception` is a value that is thrown using the throw statement.\n - `reason` is a value that indicates why a promise was rejected.\n - `settled` the final resting state of a promise, fulfilled or rejected.\n\n A promise can be in one of three states: pending, fulfilled, or rejected.\n\n Promises that are fulfilled have a fulfillment value and are in the fulfilled\n state. Promises that are rejected have a rejection reason and are in the\n rejected state. A fulfillment value is never a thenable.\n\n Promises can also be said to *resolve* a value. If this value is also a\n promise, then the original promise's settled state will match the value's\n settled state. So a promise that *resolves* a promise that rejects will\n itself reject, and a promise that *resolves* a promise that fulfills will\n itself fulfill.\n\n\n Basic Usage:\n ------------\n\n ```js\n let promise = new Promise(function(resolve, reject) {\n // on success\n resolve(value);\n\n // on failure\n reject(reason);\n });\n\n promise.then(function(value) {\n // on fulfillment\n }, function(reason) {\n // on rejection\n });\n ```\n\n Advanced Usage:\n ---------------\n\n Promises shine when abstracting away asynchronous interactions such as\n `XMLHttpRequest`s.\n\n ```js\n function getJSON(url) {\n return new Promise(function(resolve, reject){\n let xhr = new XMLHttpRequest();\n\n xhr.open('GET', url);\n xhr.onreadystatechange = handler;\n xhr.responseType = 'json';\n xhr.setRequestHeader('Accept', 'application/json');\n xhr.send();\n\n function handler() {\n if (this.readyState === this.DONE) {\n if (this.status === 200) {\n resolve(this.response);\n } else {\n reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));\n }\n }\n };\n });\n }\n\n getJSON('/posts.json').then(function(json) {\n // on fulfillment\n }, function(reason) {\n // on rejection\n });\n ```\n\n Unlike callbacks, promises are great composable primitives.\n\n ```js\n Promise.all([\n getJSON('/posts'),\n getJSON('/comments')\n ]).then(function(values){\n values[0] // => postsJSON\n values[1] // => commentsJSON\n\n return values;\n });\n ```\n\n @class Promise\n @param {Function} resolver\n Useful for tooling.\n @constructor\n*/\n\nvar Promise$1 = function () {\n function Promise(resolver) {\n this[PROMISE_ID] = nextId();\n this._result = this._state = undefined;\n this._subscribers = [];\n\n if (noop !== resolver) {\n typeof resolver !== 'function' && needsResolver();\n this instanceof Promise ? initializePromise(this, resolver) : needsNew();\n }\n }\n\n /**\n The primary way of interacting with a promise is through its `then` method,\n which registers callbacks to receive either a promise's eventual value or the\n reason why the promise cannot be fulfilled.\n ```js\n findUser().then(function(user){\n // user is available\n }, function(reason){\n // user is unavailable, and you are given the reason why\n });\n ```\n Chaining\n --------\n The return value of `then` is itself a promise. This second, 'downstream'\n promise is resolved with the return value of the first promise's fulfillment\n or rejection handler, or rejected if the handler throws an exception.\n ```js\n findUser().then(function (user) {\n return user.name;\n }, function (reason) {\n return 'default name';\n }).then(function (userName) {\n // If `findUser` fulfilled, `userName` will be the user's name, otherwise it\n // will be `'default name'`\n });\n findUser().then(function (user) {\n throw new Error('Found user, but still unhappy');\n }, function (reason) {\n throw new Error('`findUser` rejected and we're unhappy');\n }).then(function (value) {\n // never reached\n }, function (reason) {\n // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.\n // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.\n });\n ```\n If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.\n ```js\n findUser().then(function (user) {\n throw new PedagogicalException('Upstream error');\n }).then(function (value) {\n // never reached\n }).then(function (value) {\n // never reached\n }, function (reason) {\n // The `PedgagocialException` is propagated all the way down to here\n });\n ```\n Assimilation\n ------------\n Sometimes the value you want to propagate to a downstream promise can only be\n retrieved asynchronously. This can be achieved by returning a promise in the\n fulfillment or rejection handler. The downstream promise will then be pending\n until the returned promise is settled. This is called *assimilation*.\n ```js\n findUser().then(function (user) {\n return findCommentsByAuthor(user);\n }).then(function (comments) {\n // The user's comments are now available\n });\n ```\n If the assimliated promise rejects, then the downstream promise will also reject.\n ```js\n findUser().then(function (user) {\n return findCommentsByAuthor(user);\n }).then(function (comments) {\n // If `findCommentsByAuthor` fulfills, we'll have the value here\n }, function (reason) {\n // If `findCommentsByAuthor` rejects, we'll have the reason here\n });\n ```\n Simple Example\n --------------\n Synchronous Example\n ```javascript\n let result;\n try {\n result = findResult();\n // success\n } catch(reason) {\n // failure\n }\n ```\n Errback Example\n ```js\n findResult(function(result, err){\n if (err) {\n // failure\n } else {\n // success\n }\n });\n ```\n Promise Example;\n ```javascript\n findResult().then(function(result){\n // success\n }, function(reason){\n // failure\n });\n ```\n Advanced Example\n --------------\n Synchronous Example\n ```javascript\n let author, books;\n try {\n author = findAuthor();\n books = findBooksByAuthor(author);\n // success\n } catch(reason) {\n // failure\n }\n ```\n Errback Example\n ```js\n function foundBooks(books) {\n }\n function failure(reason) {\n }\n findAuthor(function(author, err){\n if (err) {\n failure(err);\n // failure\n } else {\n try {\n findBoooksByAuthor(author, function(books, err) {\n if (err) {\n failure(err);\n } else {\n try {\n foundBooks(books);\n } catch(reason) {\n failure(reason);\n }\n }\n });\n } catch(error) {\n failure(err);\n }\n // success\n }\n });\n ```\n Promise Example;\n ```javascript\n findAuthor().\n then(findBooksByAuthor).\n then(function(books){\n // found books\n }).catch(function(reason){\n // something went wrong\n });\n ```\n @method then\n @param {Function} onFulfilled\n @param {Function} onRejected\n Useful for tooling.\n @return {Promise}\n */\n\n /**\n `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same\n as the catch block of a try/catch statement.\n ```js\n function findAuthor(){\n throw new Error('couldn't find that author');\n }\n // synchronous\n try {\n findAuthor();\n } catch(reason) {\n // something went wrong\n }\n // async with promises\n findAuthor().catch(function(reason){\n // something went wrong\n });\n ```\n @method catch\n @param {Function} onRejection\n Useful for tooling.\n @return {Promise}\n */\n\n\n Promise.prototype.catch = function _catch(onRejection) {\n return this.then(null, onRejection);\n };\n\n /**\n `finally` will be invoked regardless of the promise's fate just as native\n try/catch/finally behaves\n \n Synchronous example:\n \n ```js\n findAuthor() {\n if (Math.random() > 0.5) {\n throw new Error();\n }\n return new Author();\n }\n \n try {\n return findAuthor();

Promise ? initializePromise(this, resolver) : needsNew();\n }\n }\n\n /**\n The primary way of interacting with a promise is through its `then` method,\n which registers callbacks to receive either a promise's eventual value or the\n reason why the promise cannot be fulfilled.\n ```js\n findUser().then(function(user){\n // user is available\n }, function(reason){\n // user is unavailable, and you are given the reason why\n });\n ```\n Chaining\n --------\n The return value of `then` is itself a promise. This second, 'downstream'\n promise is resolved with the return value of the first promise's fulfillment\n or rejection handler, or rejected if the handler throws an exception.\n ```js\n findUser().then(function (user) {\n return user.name;\n }, function (reason) {\n return 'default name';\n }).then(function (userName) {\n // If `findUser` fulfilled, `userName` will be the user's name, otherwise it\n // will be `'default name'`\n });\n findUser().then(function (user) {\n throw new Error('Found user, but still unhappy');\n }, function (reason) {\n throw new Error('`findUser` rejected and we're unhappy');\n }).then(function (value) {\n // never reached\n }, function (reason) {\n // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.\n // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.\n });\n ```\n If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.\n ```js\n findUser().then(function (user) {\n throw new PedagogicalException('Upstream error');\n }).then(function (value) {\n // never reached\n }).then(function (value) {\n // never reached\n }, function (reason) {\n // The `PedgagocialException` is propagated all the way down to here\n });\n ```\n Assimilation\n ------------\n Sometimes the value you want to propagate to a downstream promise can only be\n retrieved asynchronously. This can be achieved by returning a promise in the\n fulfillment or rejection handler. The downstream promise will then be pending\n until the returned promise is settled. This is called *assimilation*.\n ```js\n findUser().then(function (user) {\n return findCommentsByAuthor(user);\n }).then(function (comments) {\n // The user's comments are now available\n });\n ```\n If the assimliated promise rejects, then the downstream promise will also reject.\n ```js\n findUser().then(function (user) {\n return findCommentsByAuthor(user);\n }).then(function (comments) {\n // If `findCommentsByAuthor` fulfills, we'll have the value here\n }, function (reason) {\n // If `findCommentsByAuthor` rejects, we'll have the reason here\n });\n ```\n Simple Example\n --------------\n Synchronous Example\n ```javascript\n let result;\n try {\n result = findResult();\n // success\n } catch(reason) {\n // failure\n }\n ```\n Errback Example\n ```js\n findResult(function(result, err){\n if (err) {\n // failure\n } else {\n // success\n }\n });\n ```\n Promise Example;\n ```javascript\n findResult().then(function(result){\n // success\n }, function(reason){\n // failure\n });\n ```\n Advanced Example\n --------------\n Synchronous Example\n ```javascript\n let author, books;\n try {\n author = findAuthor();\n books = findBooksByAuthor(author);\n // success\n } catch(reason) {\n // failure\n }\n ```\n Errback Example\n ```js\n function foundBooks(books) {\n }\n function failure(reason) {\n }\n findAuthor(function(author, err){\n if (err) {\n failure(err);\n // failure\n } else {\n try {\n findBoooksByAuthor(author, function(books, err) {\n if (err) {\n failure(err);\n } else {\n try {\n foundBooks(books);\n } catch(reason) {\n failure(reason);\n }\n }\n });\n } catch(error) {\n failure(err);\n }\n // success\n }\n });\n ```\n Promise Example;\n ```javascript\n findAuthor().\n then(findBooksByAuthor).\n then(function(books){\n // found books\n }).catch(function(reason){\n // something went wrong\n });\n ```\n @method then\n @param {Function} onFulfilled\n @param {Function} onRejected\n Useful for tooling.\n @return {Promise}\n */\n\n /**\n `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same\n as the catch block of a try/catch statement.\n ```js\n function findAuthor(){\n throw new Error('couldn't find that author');\n }\n // synchronous\n try {\n findAuthor();\n } catch(reason) {\n // something went wrong\n }\n // async with promises\n findAuthor().catch(function(reason){\n // something went wrong\n });\n ```\n @method catch\n @param {Function} onRejection\n Useful for tooling.\n @return {Promise}\n */\n\n\n Promise.prototype.catch = function _catch(onRejection) {\n return this.then(null, onRejection);\n };\n\n /**\n `finally` will be invoked regardless of the promise's fate just as native\n try/catch/finally behaves\n \n Synchronous example:\n \n ```js\n findAuthor() {\n if (Math.random() > 0.5) {\n throw new Error();\n }\n return new Author();\n }\n \n try {\n return findAuthor();
