Introduction to OpenUI5

OpenUI5 is a JavaScript application framework designed to build cross-platform, responsive, enterprise-ready applications. It is an open-source project maintained by SAP SE available under the Apache 2.0 license and open to contributions. OpenUI5’s core is based on JavaScript, jQuery, and LESS. The library’s feature set includes model–view–controller patterns, data binding, its own UI-element library, and internationalization support.

Application frameworks became popular with the rise of graphical user interfaces (GUIs), since these tended to promote a standard structure for applications. Programmers find it much simpler to create automatic GUI creation tools when using a standard framework, since this defines the underlying code structure of the application in advance.

The team that started the project in 2009, that eventually lead to OpenUI5 was tasked with creating a new user interface (UI) for SAP applications. Objectives included a framework that was flexible, extensible, modern, and would provide a consistent look and feel across SAP applications. In addition to this, at the time SAP’s main UI framework was tightly coupled to its backend technology, becoming a bottleneck to UI improvements.

The user interface (UI), in the industrial design field of human–computer interaction, is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators’ decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.

SAP SE is a German multinational software corporation that makes enterprise software to manage business operations and customer relations. SAP is headquartered in Walldorf, Baden-Württemberg, Germany with regional offices in 180 countries. The company has over 425,000 customers in over 180 countries and is a component of the Euro Stoxx 50 stock market index.

All OpenUI5 components are completely free, and there are no paid “premium” or “commercial” widgets:

OpenUI5 is best described as a one-stop-shop toolkit. It has everything you need to build web applications, while leaving enough flexibility to extend. And by the way, it’s the only one that gives you full functionality for free. While other popular toolkits come as a free trial with paid versions for full functionality, OpenUI5 comes as a complete product by itself – no upsells, no paid premium.

Some of the main features of OpenUI5 are:

  • 180 UI controls, grouped in cross-device (running on phones, tablets and desktops) — menu, carousel, panel, toolbar, icon tab bar, layout, responsive grid, splitter, list, table, dialog, message box, message toast, responsive popover, calendar, combo box, date range selection, file uploader, rating indicator, segmented button, slider, tags display, color picker, tree, table, tree table, etc.
  • WYSIWYG theme designer (not open sourced)
  • MVC architecture
  • Different view formats (XML, HTML, JavaScript or JSON)
  • Data binding with OData, JSON or XML models
  • I18n, including right-to-left language support
  • Consistent UX patterns across all frontend features
