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. - - Terminology - ----------- - - - `promise` is an object or function with a `then` method whose behavior conforms to this specification. - - `thenable` is an object or function that defines a `then` method. - - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). - - `exception` is a value that is thrown using the throw statement. - - `reason` is a value that indicates why a promise was rejected. - - `settled` the final resting state of a promise, fulfilled or rejected. - - A promise can be in one of three states: pending, fulfilled, or rejected. - - Promises that are fulfilled have a fulfillment value and are in the fulfilled - state. Promises that are rejected have a rejection reason and are in the - rejected state. A fulfillment value is never a thenable. - - Promises can also be said to *resolve* a value. 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; -} - -// Strange compat.. -Promise.polyfill = polyfill; -Promise.Promise = Promise; - -return Promise; - -}))); - -ES6Promise.polyfill(); -//# sourceMappingURL=es6-promise.auto.map -/* WEBPACK VAR INJECTION */}.call(exports, __webpack_require__(5), __webpack_require__(4))) - -/***/ }, - -/***/ 4: -/***/ function(module, exports) { - -var g; - -// This works in non-strict mode -g = (function() { return this; })(); - -try { - // This works if eval is allowed (see CSP) - g = g || Function("return this")() || (1,eval)("this"); -} catch(e) { - // This works if the window reference is available - if(typeof window === "object") - g = window; -} - -// g can still be undefined, but nothing to do about it... -// We return undefined, instead of nothing here, so it's -// easier to handle this case. if(!global) { ...} - -module.exports = g; - - -/***/ }, - -/***/ 49: -/***/ function(module, exports) { - -/* (ignored) */ - -/***/ }, - -/***/ 5: -/***/ function(module, exports) { - -// shim for using process in browser -var process = module.exports = {}; - -// cached from whatever global is present so that test runners that stub it -// don't break things.

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*/\nfunction 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\nPromise.all = all;\nPromise.race = race;\nPromise.resolve = resolve;\nPromise.reject = reject;\nPromise._setScheduler = setScheduler;\nPromise._setAsap = setAsap;\nPromise._asap = asap;\n\nPromise.prototype = {\n constructor: Promise,\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 \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 \n Chaining\n --------\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 \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 \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 \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 \n Assimilation\n ------------\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.
