SAP Fiori Elements Feature Map: What Is Available in Each SAPUI5 Version

If you work with SAP Fiori Elements, you have probably run into this problem before: it is hard to see in which UI5 version a specific feature was introduced. Bjorn Schulz already built a strong matrix for ABAP: ABAP Feature Matrix. For Fiori Elements and RAP/CAP, there was no comparable matrix yet. So I created an Influence request to close this gap: influence.sap.com/sap/ino/#idea/351729 The new Developer Portal would be a great home for a matrix like this but so far, there still is no official version. The closest alternative is the SAP Fiori Elements Feature Map in the SAPUI5 documentation. ...

Network Request & Response Copier: An OData-Friendly DevTools Request Viewer

AI assistants already help a lot, but they work best when you can give them good context. In web apps, the most important context is usually the real traffic between frontend and backend: request URLs, payloads, and responses. When debugging, I want to copy that information quickly and completely. And since I mostly work with UI5 and OData, I usually need the full URL plus request and response body. In Chrome DevTools that often means a lot of manuall copy pasting, and if you need more than one request, it gets annoying fast. ...

Distributed Microservices with GitHub Pages and RSS Feeds

I was recently asked how my UI5 Versions Bot on Bluesky works. So I want to simply explain how it works and how I use an RSS feed as a small “microservice” so I can base other services on this data. How the ui5-lib-diff project works The ui5-lib-diff project pulls data from official UI5 sources (SAPUI5/OpenUI5) and turns it into structured change data. That data is then used to generate an RSS feed entry for each patch update in both SAPUI5 and OpenUI5. ...
