Node-webkit app- how to update it? - node-webkit

Question

I am using node-webkit to develop apps for my students, and to provide one stop solution I would need to update node-webkit archive once in a month. Is there a way I can accomplish that?
Basically I need to replace just one html file every month, say "page1.html".
I googled but have no idea where to start.

Answer 1

On Mac, you can access the filesystem of the own app e.g.
$ ls -lh /Applications/Shock.app/Contents/Resources/app.nw/
[...]
-rw-r--r-- 1 jordi staff 2,3K 29 gen 01:47 index.html
-rw-r--r-- 1 jordi staff 467B 29 gen 01:47 lecturenotes.html
[...]
So if you put a new version on a specific URL, you could fetch it and rewrite the HTML file inside the app:
var request = require('request');
request('http://www.your-own-server.com/app/lecturenotes.html', function (error, response, body) {
if (!error && response.statusCode == 200) {
var fs = require('fs');
fs.writeFileSync('/Applications/Shock.app/Contents/Resources/app.nw/lecturenotes.html', body);
}
});
I think something similar happens on Linux. Unfortunately, the Windows version works with a binary package into the exe, so this trick won't work for the last case.

I have used App.dataPath as described in https://github.com/nwjs/nw.js/wiki/App
You can download the html files into that path. App.dataPath works platform independent , though the location is different based on the platforms , your app will have a generic path to refer the html files.
excerpt :
Get the application's data path in user's directory. Windows:
%LOCALAPPDATA%/; Linux: ~/.config/; OSX: ~/Library/Application
Support/ where is the field in the manifest.
