I saw a question on a thread this week, and decided to spend a few hours to write up the process, as well as provide an example.

This bug will cover the general conversion process, but it doesn’t cover all the idiosyncrasies / differences between the two platforms.

The example I’m going to use for the conversion is from the google chrome sample app repository:

git clone https://github.com/GoogleChrome/chrome-app-samples

The most basic example I have already converted to a packaged app the Hello World example.

git clone https://github.com/dclarke/firefox-os-sample-apps

For the most basic app that I have converted “Hello World”, we look at the following pieces and how they differ / can also possibly coexist between the two platforms.

manifest.json:

{ "manifest_version": 2, "name": "Hello World", "version": "2", "minimum_chrome_version": "23", "icons": { "16": "icon_16.png", "128": "icon_128.png" }, "app": { "background": { "scripts": ["main.js"] } } }

manifest.webapp:

{ "name": "Hello World", "description": "Hello World", "launch_path": "/index.html", "icons": { "128": "icon_128.png", "16": "icon_16.png" }, "developer": { "name": "David Clarke", "url": "https://github.com/onecyrenus/firefox-os-apps" }, "default_locale": "en", "permissions": { } }

The main difference between these two loading mechanisms is just file structure, and some syntactic sugar. So why not deploy a manifest.json and start rocking the free web !!!
