UI5ers live #46: manifest.json Best Practices & What's New in Accessibility

From routing bugs in the manifest.json to the new demands of WCAG 2.2, this episode breaks down two complex topics into practical, actionable advice. First, join UI5 community member Marco Beier and OpenUI5/SAPUI5 Chief Architect Peter Muessig as they untangle a real-world manifest.json routing problem. Starting with an issue caused by mixing legacy and modern configurations, they debug it live and reveal the common pitfalls many developers face. Learn about best practices, the importance of schema validation in VS Code, and get answers to frequent questions about manifest versions, data binding, and asynchronous content creation. Then, accessibility expert Nikolai Kolarov walks us through the latest enhancements in OpenUI5 accessibility. Discover what the new WCAG 2.2 guidelines mean for your applications, with a focus on focus appearance, single-pointer alternatives for drag-and-drop, and minimum target sizes. Nikolai also explains the significant changes introduced with WAI-ARIA 1.2 and provides a look into OpenUI5's screen-reader testing environment. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Video Chapters: 00:00 - Introduction & Agenda 01:12 - Part 1: manifest.json Best Practices 01:50 - The Routing Problem: A Live Debugging Session 02:51 - The Fix: Understanding Prefixes and Configuration 04:00 - Legacy vs. Modern Routing Explained 08:45 - Understanding and Using manifest.json Schema Validation in VS Code 11:08 - How to Debug and Use the Latest Schema 15:17 - manifest.json Q&A (CIL, Binding, Async & More) 20:52 - Part 2: Accessibility Enhancements 21:29 - What's New in WCAG 2.2? 23:39 - WCAG 2.2: Dragging Movements & Single-Pointer Alternatives 27:03 - WCAG 2.2: Ensuring Proper Target Size 30:32 - Adopting WAI-ARIA 1.2: Technical Deep Dive 32:40 - WAI-ARIA 1.2 in Practice: The List Grouping Example 34:42 - OpenUI5's Screen Reader & Reference Test Environment 37:42 - Wrap-up & Outro _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Resources: Manifest.json & Routing: UI5 manifest Q/A: https://github.com/wridgeu/UI5ers-liv... easy-ui5 Generator: https://www.npmjs.com/package/generat...
