SAP Fiori has become the go-to user experience (UX) design framework for SAP applications, providing a simple, role-based, and responsive interface. At the heart of building custom SAP Fiori apps is SAPUI5, SAP’s proprietary HTML5 framework that enables developers to create rich, enterprise-ready web applications. This article guides you through the essentials of building SAP Fiori apps with SAPUI5.
SAPUI5 is a comprehensive JavaScript framework that follows modern web development standards like HTML5, CSS3, and JavaScript. It provides a wide range of UI controls, a powerful MVC (Model-View-Controller) architecture, data binding, and support for OData services, making it ideal for building SAP Fiori apps.
Defines the UI layout and elements. Views can be created using XML, JavaScript, or JSON. XML views are most common due to their declarative and readable nature.
Example (XML View):
<mvc:View controllerName="my.namespace.controller.Main" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m">
<Page title="My Fiori App">
<content>
<Button text="Click Me" press=".onPress"/>
</content>
</Page>
</mvc:View>
Contains the event handling and business logic associated with the view.
Example:
sap.ui.define([
"sap/ui/core/mvc/Controller"
], function(Controller) {
return Controller.extend("my.namespace.controller.Main", {
onPress: function() {
sap.m.MessageToast.show("Button Pressed");
}
});
});
Manages data and business objects, supporting various types like JSON, XML, and OData. Models connect UI controls to data sources enabling dynamic content display and interaction.
Acts as the application’s entry point and defines routing, models, and app configuration.
