promise helpers (wip)

installation

$ npm install

api

prometido.when

function (Promise[]) => Promise

or function (Promise) => Promise

Aggregates an array of promises into one promise which is resolved when every constituent promise is resolved or rejected when some constituent promise is rejected

prometido.reduce

function (arr, reducerFn, seedValue) => Promise

where the reducerFn has the interface

function (accumulatedValue, currentValue, deferred)

reducerFn can either return a sync value or resolve/reject the deferred argument

prometido.reduceRight

like prometido.reduce, but with the reducerFn applied in right-to-left order over the values arr.

prometido.pCall

function (fn, arg1 ... argN) => Promise

call a function (without this context), ensuring that return value is a Promise and trapping thrown exceptions as a rejected Promise

prometido.asPromise

function (val) => Promise

uses heuristics to ensure that val is a promise. If val is already a promise, it is passed through, otherwise val is returned as a new resolved Promise.

prometido.asRejectedPromise

function (err) => Promise

ensures that err is an Error and returns it as a rejected Promise.

running the tests

$ npm test
