Building a model application with Theia and EMF.cloud the DISCO experience
summary
DISCO is a satellite-database modeler built by plugging the EMF.cloud model server on top of an existing EMF-based framework and delivering Theia + Electron HMIs. The build uses a complex custom persistence and command model, implements a tree view with columns, JSON Forms properties, and an Xtext LSP Monaco editor; model validation maps into the Problems view. Key hurdles are synchronous vs async updates, lazy loading for large models and custom codecs; those are solved and the desktop/web UI is functional for 100+ MB models.
