The Link HTML5 SDK

The Link HTML5 SDK by Mobile Helix is an open-source HTML5 SDK for building enterprise applications using either HTML5/CSS3/JavaScript or JSF2/HTML5/CSS3/JavaScript. Applications built using the SDK will operate across any platform, including mobile devices (using mobile Safari for iOS or Chrome), laptops/desktops (using either Chrome or Safari), or within the Link Container, integrated into the Link product from Mobile Helix. Integration with the Link Container provides transparent data security, authentication, and key management, all of which must be implemented by the particular application if it runs in a standard browser without Link.

Full documentation is in the /doc directory.

A small demo application is in the /demo directory and is a great way to get started with building off-line first HTML5 web apps.

Full SDK documentation is in the /doc directory. file LinkSDKMasterDocumentation provides an overview of the SDK and documents a subset of the capabilities available in the SDK. We are still in Alpha, so the documentation is lagging a bit behind the capabilities of the product. Should you wonder if a particular feature of interest is available in the SDK, please feel free to contact us at


The Link SDK is licensed under the Apache License, Version 2.0. This license enables free usage in both commercial and non-commercial contexts, and we intend to keep it that way. Individual components are governed under separate license when applicable (e.g., jQuery Mobile and jQuery are governed by the MIT License), but we have taken care to ensure that each component is fully open and free software, with no "copy-left" provisions used in any GPL, LGPL, or AGPL license. Most components are licensed under an MIT, BSD, or Apache-style license with a few variations on that theme. As we complete our documentation we will take care to clearly explain any licensing implications of the various 3rd party components.

jQuery Mobile

At the heart of the Link HTML5 SDK is jQuery Mobile, v1.3.1. In addition, we have wrapped certain jQM components in our on plugins to provide additional features, such as native-style scrolling on touch devices and rich-text editing. We have also added a number of features to simplify client-side DOM generation for common enterprise tasks, like displaying and editing form data.

Data Storage

On top of the jQuery Mobile UI layer, we have integrated, enhanced, and fixed the PersistenceJS O-R-M library such that it provides an access layer to HTML5's offline storage. Our AJAX libraries enable a simple integration with any back-end servlet that returns objects serialized as JSON data. Using this integration these objects are automatically converted into database schema and stored. We currently support webSQL as an underlying browser storage mechanism, but IndexedDB support is in the roadmap.

Integration with JSF and PrimeFaces

Finally, we have built a JSF2 integration as a derivative of the PrimeFaces Mobile project. The render kit and components that we have built can be used in conjunction with PrimeFaces and PrimeFaces Extensions. In the near future we intend to make our library co-exist with PrimeFaces Mobile as well, so that users can benefit from the best of all aspects of the PrimeFaces component suite. We also intend to make our JSF integration function standalone without PrimeFaces. Stay tuned for our progress on these items.

Collaborate with Us!

We hope to build an active and thriving community of enterprise HTML5 developers who take advantage of the Link SDK to build world-class apps that run on any platform, mobile or fixed. To that end, we are open to your questions, issue reports, pull requests, etc. Feel free to download the SDK and give it a try, with the major caveat that until stated otherwise the SDK is in Alpha. That said, our production release is not far away so most of the basic functionality available in the SDK is working.

Can I see a Demo?

YES! We now have a demo app in the /demo folder. This is a great way to get started with the SDK. Take a look at the file in the /demo folder for more information and a pointer to some explanatory slides.
