UI5 Linter Workshop - Sample App

UI5con 2026 Germany Hands-on Workshop: UI5 Linter in Action: Integrating It Into Your Development Process

This repository contains the demo project for the UI5 linter Hands-On at UI5con 2026. It is a variant of the OpenUI5 Todo sample application available at github.com/UI5/sample-app.

About the Workshop

Modernize a legacy UI5 app end-to-end using UI5 linter — from your first ui5lint report to a clean, CSP-compliant, future-proof codebase. You'll auto-fix what you can, manually resolve the rest, and wire linting into your workflow and CI so regressions never sneak back in.

Prerequisites: Laptop with Node.js (LTS) and Git installed, a code editor, and basic UI5 development experience.

(Optional Outlook) Coding Agents Support:
If you'd like to automate the modernization steps you've learned here, check out the UI5 Modernization Plugin — a coding‑agent toolkit that builds on the UI5 linter and orchestrates a five‑phase modernization with per‑phase verification and commits. Learn more in the SAP Community Blogpost.

About This Demo Project

Important

This project intentionally contains legacy code patterns for educational purposes. Attendees will identify and fix these issues step-by-step during the workshop using the UI5 linter.

Do not use this code as a reference for best practices! The legacy patterns include:

• Deprecated APIs (jQuery.sap.*, sap.ui.controller(), etc.)
• Global variable access
• Deprecated themes and libraries
• CSP-violating inline scripts
• Legacy test setup

Checkout github.com/UI5/sample-app for the original version of this application, following best practices and using modern API.

Final Result

The modernized version of this application (with all linter issues resolved) is available on the final-result branch.
