nw-angular-updater

Node Webkit Angular Updater Service

How it works

• infoUrl must point to a json file which has a version property with an integer value.
• downloadUrl must point to the Node Webkit packaged app
  ** https://github.com/nwjs/nw.js/wiki/How-to-package-and-distribute-your-apps
• filename is the file name to be overwritten when the download completes. It must exist (or there wouldn't be nothing to update, would it?)
• currentVersion Sets the current app version, to match against the one from infoUrl
• auto (optional; Defaults to true) Automatically downloads new package (if needed) upon app execution. Otherwise, it just checks if an update is needed.

1. Upon app execution, it queries infoUrl and parses its json for the property version
2. If version is greater than currentVersion, it starts downloading from downloadUrl
3. When the download completes, it renames the downloaded file to filename

How to use:

Install through bower

bower i --save nw-angular-updater

Then add 'nwUpdater' as a dependency

app = angular.module('yourApp', ['nwUpdater'])

Now you need to configure the provider with the required values

app.config(function(nwUpdateProvider) {
  nwUpdateProvider
  .setInfoUrl('http://url.to/latest.info')
  .setDownloadUrl('http://url.to/latest.nw')
  .setFilename('yourapp.nw')
  .setCurrentVersion 1
})

Then you just inject it into a controller

app.controller('yourController', ['nwUpdate', function(nwUpdate) {
});

And you're set.
