SAP OpenUI5 javascript library basics| OpenUI5 with examples

In this post, we will delve into the fundamentals of OpenUI5 tutorials.

Introduction to SAP OpenUI5

OpenUI5 is a contemporary open-source JavaScript framework designed for constructing Software Web applications based on the HTML5 specification.

Developed by SAP as an open-source project, OpenUI5 is responsive and interactive, supporting all devices and major browsers. It is akin to the SAPUI5 framework.

The framework encompasses over 200 inbuilt components and requires a basic understanding of JavaScript, HTML, and CSS technologies for effective learning.

OpenUI5 facilitates rapid application development, providing a spectrum of UI widgets from simple elements like buttons and dropdowns to complex structures like grids and trees.

OpenUI5 Features

  • Over 200 UI components
  • Model-View-Controller (MVC) support for data binding
  • Support for Remote API integration with formats such as JSON, XML, and ODATA
  • Internalization support for localization and globalization
  • Responsive design compatible with desktops, tablets, and mobile devices
  • Browser support across major platforms
  • Availability of popular widgets, layout themes, and extensible capabilities
  • Open-source framework with support for hybrid application development and deployment
  • Consistent and rich User Experience (UX) design principles
  • Two-way data binding and keyboard interaction


  • Facilitates rapid application development
  • Ensures a consistent UI across all devices
  • Large community support due to SAP’s development
  • Enhanced productivity with a wide range of available UI components
  • Lower learning curve based on JavaScript, HTML5, and CSS

IDE and Tools Support

OpenUI5 is extensible with numerous plugins and tools catering to various Integrated Development Environments (IDEs) and editors. Although there’s no specific IDE recommendation, Eclipse serves as the primary choice for OpenUI5 application development.

SAP UI development tools are available as plugins for Sublime Text and Webstorm IDEs, as well as for Eclipse. Both SAP UI5 and Op`enUI5 offer rich control sets.

While SAP UI5 is part of the SAP product suite, OpenUI5 is an open-source project released under the Apache license. Both are essentially the same with different licenses.

For development without local setup, you can use SAP Web IDE, a cloud IDE provided by SAP.

SAP OpenUI5 Hello World Example

To write OpenUI5 applications, you need to download the runtime library and Software Development Kit (SDK). Both are essential for running applications, including mobile apps.

The code can be deployed to any web server. In the provided example, the CDN library is used.

<!doctype html>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <title>SAPUI OpenUI5 Demo Applicaotn</title>

      var oBtn;

      oBtn = new sap.ui.commons.Button({
        text: "Button Sample Demo",
        press: function (oEvent) {
  <body class="sapUiBody">
    <div id="main"></div>

The example includes a button, and upon clicking it, an alert displays its content—a simple hello world example showcasing OpenUI5 code.

SAP Fiori Design Library

All OpenUI5 controls are based on the Fiori library. SAP Fiori is a design language offering a rich and consistent User Experience (UX) across various components, themes, and devices.

Fiori provides both simple and complex controls that can be seamlessly integrated into front-end applications.

Fiori Design Principles

  • Customizable design based on specific needs
  • Ease of use and integration
  • Consistent UX across all devices
  • Fluid user experience
