JavaScript as a Crime Scene – Improve your Architecture with a Forensic Analysis!
Software solutions must be maintainable in the long term, and good modularization supports this. But how do you know whether the originally defined structure is still viable? How do you find out where improvements are needed?
In this session, we investigate forensic code analysis, which examines source code together with historical information from your source code control system to uncover hidden valuable patterns. We discuss what’s behind Hotspots, Change Coupling, and Team/Code Alignment and what they tell us about your architecture.
By the end, you will know how to use a Forensic Analysis to ensure long-term maintainability for your solutions.

Workshop
In this interactive workshop, we use Angular's latest features to build a modern and maintainable architecture for large applications. We start with a sustainable project setup using Nx with Module Boundaries and Sheriff.
We continue with integrating Signals that will shape the future of the framework and leverage the new Resource API including the httpResource for establishing a reactive design. Then, we use the brand-new NGRX Signal Store to establish modern and lightweight state management patterns.
In the end, you will know how you can use the individual tools to design modern and, above all, long-term maintainable Angular architectures.
What’s new in the Fall 2025 Edition?
✔️ Using Forensic Analyses for investigating the “healthiness” of your architecture
✔️ Strong focus on reactive architectures with Signals and the httpResource
✔️ Strong focus on state management patterns with the NgRx Signal Store
