Build Web Applications

Mobile applications can be downloaded completely ahead of time (at least the layout logic)

The server is only required to fetch new data or perform actions through web services

A website today, however- makes however little use of the client

capabilities- serves mostly static content- needs constant connection

Most of the layout proccess happens on the server and the client only receive content to display

The use of ASP or PHP when constructing the page itself is making it impossible to cache efficiently

A web application is a Client-like application using the Web stack and platform. It should offer offline capabilities and caching.

Web Application

A classical website build using the same principles as Web Applications, relying on the browser-implemented caches.

Website as an Application

Fast website, low bandwidth usage

Easy to build applications, easy for others to consume data and create application using your data (you can monetize)

Offline access, separation of data and layout both on the server and the client, and both can be cached independently by the appropriate storage

The tools already exist today. Windows 8 is using IE10. webOS used Webkit. You can start building your apps nox!

The tools

JSON WebServices + AJAX• Everything you do on your website should

be done by a webservice call using a js-httprequest

• Use only static HTML, JS and CSS file for your site

• Don’t rely on <form> POST, only on WCF+JSON

AJAX Extension for jQuery• Transform your webservices into JS• Allow you to use complex JSON

representation• Or use your own API (more possibilities = more work)

sessionStorage and localStorage• Up to 10 Mo for your application to store

data• An addition to the traditionnal cache• Very easy to use and already implemented

(IE8+)

• Can be emulated with cookies for older browsers

SVG and HTML Canvas• Generating graphics should be done

locally (if possible)

• It was a complex task before, but it has been made a lot easier with SVG and HTML Canvas

• Generating graphics locally give you more freedom
