Creating HTML5-based apps for the Mac App Store - html

The new Tweetdeck for the Mac is supposedly HTML5-based:

Anyone know how to build a HTML5 app for the Mac App Store like this? I can't find any documentation on it.

My guess is they do something similar to what PhoneGap does - add a webview in an XCode project. Webviews are basically embedded browsers that can run html5 and javascript. Then, they code their pages in html5 and can call their dataservices via ajax.
Here is actually a tutorial on how to add your html5 code to a webview in xcode: http://www.lostdecadegames.com/how-to-embed-html5-into-a-native-mac-osx-app/

Check out this http://www.tidesdk.org/ build apps with html5

Today you have some great tools made to build Mac OS X applications with HTML5/CSS3 and JavaScript. Like Sentenza Desktop : http://codecanyon.net/item/sentenza-desktop-for-mac/4070984

NW.js lets you call all Node.js modules directly from DOM and enables a new way of writing applications with all Web technologies. It was previously known as "node-webkit" project.

How to build a Today Widget / App Extension with Cordova?

An app I am working on needs a Today Extension / Widget. Are there any resources on how to build one into an Cordova app?
I found this, but it's not written very clearly and from what I understood seems to be a native app that only uses a HTML5 element in the app and widget to display some data :/
Yes you are right, today extension are a native thing. I recently also did a lot of research on how to integrate one into a cordova project dynamically and ended up creating my own cordova-plugin for that. You can find it here, maybe it will be useful for you too! Nevertheless you will have to implement the widget in Swift.
The plugin takes an already developed widget and integrates it in an cordova-ios project on every cordova platform add ios using a hook which parses and modifies the project.pbxproj via the help of cordova-node-xcode.

Decode a chrome app or extension

I found a chrome app for photography effects which works offline perfectly. But it is having limited features. I have some ideas to add for my use. But I'll require to develop complete app. That'll take more time.
Is there any way so I can modify the app for my personal use?
Well!! I got to know that all chrome extensions/apps are made in HTML & JS. So I can easily decode them by using some chrome crx file downloader or directly from its extension folder.

Windows Store WinJS App and LESS

Is it possible to use LESS files in a WinJS application for the Windows Store?
I like how the Web Essentials extension works with web apps and would like to have this functionality in my WinJS app.
Yes, as long as you've got it setup to compile and you add the output CSS files to your project, it works fine. I'm using it in a WinJS project.

I am building a HTML5 app via Dreamweaver 5.5 and want to use the childbrowser plugin to display a url internally - can anyone offer any advice on to do this? I'm struggling to implement. Or an alternative method to display a url within an app rather than safari?
