plite2

Tiny, light-weight JavaScript promises. Fork of Chris Davies' Plite, to make it compatible with NPM/Browserify and allow combination of multiple promises (Plite.all()).

Note that Alite has been removed from the package. Please refer to the original repo if you need that.

Usage

Require plite2

var Plite = require('plite2');

Create a promise:

var p = new Plite();

Resolve a promise:

p.resolve('Hey, that was successful!');

Reject a promise:

p.reject('Utter failure.');

Chain stuff along:

p.then(function (msg) {
    return msg + ' on ' + new Date().toString();
}).then(function (msg) {
    alert('GOOD: ' + msg);
}).catch(function (err) {
    alert('ERR: ' + err);
}).finally(function () {
    alert('All done!');
});

Combine promises:

var p1 = new Plite();
var p2 = new Plite();

setTimeout(function () {
  p1.resolve();
}, 1000);

setTimeout(function () {
  p2.resolve();
}, 2000);

Plite.all([p1, p2]).then(function () {
  alert("All done!");
});

Limitations

This is a very simple implementation. It is intended to be used to chain promises, resolve, and reject. It really isn't intended for any other use. It does what I need a promise to do, and no more...
