HTML 5 App Development services

WHAT IS AN HTML5 APP?

Source

HTML5 apps offer write once, run anywhere mobile app

development.

HTML5 apps are a collection of webpages optimized for mobile

devices that bring advanced capabilities for streaming video and

audio data, handling graphics and animation and providing offline

support.

They also add semantic elements, form controls and multimedia

components, as well as a number of new APIs that

support geolocation services, drag-and-drop operations, local

application caching and more. Source

HTML5 seldom works alone.

Most HTML5 apps integrate Cascading Style Sheets (CSS), which

define how the HTML components render within a browser,

and JavaScript, which includes the APIs for working with text,

objects and arrays.

All major browsers support these technologies, making it possible

to implement Web-based apps across a wide range of devices.

FRAMEWORKS FOR HTML5 APP DEVELOPMENT

Source

• jQuery Mobile - jQuery Mobile, is a unified user interface system

across all popular mobile device platforms, built on jQuery and

jQuery UI.

• Appear IQ - Appear IQ is a mobility platform that simplifies the

development and management of context-aware hybrid mobile web

applications (HTML5, CSS3, JavaScript), native mobile applications as

well as their integration with enterprise IT systems. It allows

developers to make use of their web skills to craft powerful mobile

applications that are optimized to the end user's needs.

• Google Web Toolkit - Google Web Toolkit is a web app framework

that can be used for developing mobile html5 apps in Java, especially

in combination with optimized mobile widget libraries such as m-gwt

• JavaScript - JavaScript, is a scripting language built into nearly every

modern browser. In Windows 8 and Windows RT (both HTML

Application and Windows Runtime), any HTML5 apps fully supported

mobile operating systems (Firefox OS and WebOS, Tizen and Ubuntu

Touch), event handling in HTML5 apps is made possible by JavaScript.

WHAT TO KEEP IN MIND WHEN BUILDING HTML5 APPS?

Source

• Memory and performance limitations are key considerations for HTML5

mobile application development.

• Not only should developers carefully control page flow, but also how the DOM

is implemented. The more complex the object model, the longer it takes to

navigate.

• Developers should keep UX in mind. To ensure quality UX, HTML5 mobile

apps should be lightweight so performance doesn't lag.

• Admins should test the app on various platforms to account for different

device types, screen sizes, browsers and operating systems.

HTML5 CAN DO EVERYTHING NATIVE CAN DO

Source

• HTML5 by itself can only do what the browser can do. When compared to

everything a native application can do that isn’t a lot.

• With PhoneGap though, that doesn’t really matter. The browser can talk to

PhoneGap and PhoneGap can talk to the device, so the browser has access to

everything that a native application does. The process may be a little more

convoluted, but it’s certainly possible – and since there’s PhoneGap plugins

available for just about everything you’ll ever need to do it’s pretty easy to

implement native functionality.

• If you want to learn more about PhoneGap and PhoneGap Build you can download

PROS OF HTML 5 APP DEVELOPMENT

Source

Source

• Hybrid mobile apps allow code reuse across platforms.

• Let the library or framework you are using take care of the platform specific

differences and use the same JavaScript code on both platforms.

• JavaScript is something that many developers are already familiar with where

something like the iOS development tools are more specialized. It can be argued

that there is less of a learning curve when developing hybrid mobile apps compared

to native apps.

• The app's interface and logic can be built and debugged in the web browser using

an emulation framework. This could lower development costs depending on the tools

required to develop native apps for the target platforms.
