nightshift-bluebird

This NightShift plugin replaces native ES6 promises by bluebird promises.

Setup

Bluebird promises can be added to NightShift as a plugin.

var nightShift = require('nightshift-core');
var bluebird = require('nightshift-bluebird');

nightShift.plugin(bluebird);

Working with Promises

NightShift encourages the usage of promises instead of callback functions.

NightShift supports two ways of working with promises: one that creates a new promise for an executor function (like ES6 or bluebird), and the other one that creates a deferred object (like Q).

Promise

nightShift.promises.Promise is the bluebird's constructor function.

newPromise(executor)

The method nightShift.promises.newPromise(executor) creates a new bluebird promise.

var promise = nightShift.promises.newPromise(function (resolve, reject) { 
    ... 
});

defer()

The method nightShift.promises.defer() creates a deferred object that exposes the associated bluebird promise as well as the resolving functions that can be used to change its state.

var deferred = nightShift.promises.defer();

var promise = deferred.promise;

// use deferred.resolve(...) or deferred.reject(...) to change the state of the promise
