NW.js (previously known as "node-webkit") allows TiddlyWiki to be set up as a native application for Windows, Mac OS X or Linux.

Setting up

1. Create a folder with the following contents:
   1. The appropriate copy of NW.js for your platform, downloaded from https://github.com/nwjs/nw.js
   2. Your TiddlyWiki HTML file as index.html
   3. A file called package.json with the following content:

      {
          "name": "tiddlywiki",
          "main": "./index.html",
      	"window": {
      		"toolbar": true,
      		"width": 1024,
      		"height": 768
      	}
      }

2. Run the NW.js application
   • If it doesn't work, you may need to unblock the application before your operating system will run it
     • OS X: see http://support.apple.com/kb/PH14369
3. Try saving changes in the usual way

Limitations

MP3 audio and H264 video are not supported without special steps described on the NW.js wiki.
