Tutorial for SAPUI5/OpenUI5 with reactive MobX model (Plunker).
Starting from a SAPUI5 app with validation and MessageManager, this tutorial shows you how you can extend an existing app with reactive components step-by-step.
No need to rewrite everything. Reactive features can be introduced on top of the original code.
Built with unofficial UI5 bindings for mobx.
UI5 bindings are a fork of Christian Theilemann's work, now seemingly abandoned.
Huge thanks to Christian Theilemann, also for his excellent blog post and insights Reactive state management in SAPUI5 via MobX.
