Itty bitty little widdle twinkie pinkie ES2015 Promise implementation
There are tons of Promise implementations out there, but all of them focus on browser compatibility and are often bloated with functionality.
This module is an exact Promise specification polyfill (like native-promise-only), but in Node.js land (it should be browserify-able though).
$ npm install --save pinkie
var fs = require('fs');
var Promise = require('pinkie');
new Promise(function (resolve, reject) {
fs.readFile('foo.json', 'utf8', function (err, data) {
if (err) {
reject(err);
return;
}
resolve(data);
});
});
//=> Promise
pinkie
exports bare ES2015 Promise implementation and polyfills Node.js rejection events. In case you forgot:
Returns new instance of Promise
.
Required
Type: function
Function with two arguments resolve
and reject
. The first argument fulfills the promise, the second argument rejects it.
Returns a promise that resolves when all of the promises in the promises
Array argument have resolved.
Returns a promise that resolves or rejects as soon as one of the promises in the promises
Array resolves or rejects, with the value or reason from that promise.
Returns a Promise object that is rejected with the given reason
.
Returns a Promise object that is resolved with the given value
. If the value
is a thenable (i.e. has a then method), the returned promise will "follow" that thenable, adopting its eventual state; otherwise the returned promise will be fulfilled with the value
.
