How to develop mobile applications using HTML5?

Under the right circumstances, HTML5 apps provide an enterprise with a simple alternative to native app development, especially as more HTML5 development frameworks emerge. Any organization faced with implementing mobile apps across multiple platforms should at least consider HTML5.

HTML5 apps are not without challenges though. They bring performance and security concerns and raise issues around accessing data and native application program interfaces (APIs). The user experience can also suffer with HTML5 apps when compared to native apps.

HTML5 mobile application development framework toolkits contain libraries of CSS and JavaScript files that developers can include in the HTML. Frameworks handle many of the issues that arise with building HTML5 apps.

Slight differences in devices and browsers do affect how an application works in one environment over the other. As a result, developers sometimes build apps based on the lowest common denominator to ensure they function across all environments, which can hurt user experience (UX). Despite the potential issues, developers with proper training and experience should have no problem delivering secure, high-performance Web-based apps.

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.

Above all, developers should keep UX in mind. To ensure quality UX, HTML5 mobile apps should be lightweight so performance doesn't lag. In addition, admins should test the app on various platforms to account for different device types, screen sizes, browsers and operating systems. Most apps also need to support offline operations to account for disruptions in connectivity.
