Package Exports

bauer-promise

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bauer-promise) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

node-bauer-promise

This is just another promise library. It relies on Thisable and unlike the compliant implementations, it features the possibility of binding context to callbacks.

Installation

npm install bauer-promise

Usage

var P = require("bauer-promise");

P.defer(); // returns a deferred object
P.defer(object); // binds object to the created promise

P.when(value); // returns a promise resolved with value
P.when(a,b,c,d); // returns a promise resolved with an array [a,b,c,d]
P.when(promise,promise,promise) // wait until all promises are resolved

Deferred

Constructor

Creates a common deferred object.

var deferred = P.defer()
// same as
var deferred = new P.cls.Deferred()

Creates a deferred object with the passed object bound to the promise.

var deferred = P.defer(object)
// same as
var deferred = new P.cls.Deferred(object)

.bind

Binds the passed object to the deferreds promise.

deferred.bind(object);
// same as
deferred.promise.bind(object);

.resolve

Fulfills the promise with the passed value.

deferred.resolve(value);

.reject

Rejects the promise with the passed value.

deferred.reject(value);

.promise

Holds the promise itself. This is what should be returned when writing an async procedure.

var deferred = P.defer();
fs.readFile("path/to/file",function(error,content) {
    if (error) {
        deferred.reject(error);
    } else {
        deferred.resolve(content);
    }
});
return deferred.promise;
