Although Angular doesn't impose strict limits on the number of files, in my view, there are too many of them in the current demo. The closest comparison is the CardView/FieldTemplate setup, but there the demo is broken down by visual components.
Proposal: keep app/components/* (the three components are justified), but consolidate types.ts, data.ts, chat-router.ts, grid-commands.ts, and form-commands.ts into app.service.ts and app/ai/ai.service.ts, following the reference examples.

Agreed on the general direction - grouping by concern instead of by technical layer makes sense, and types.ts + data.ts are small enough that they don't need their own files; I'll fold them together. I'd hold off on merging everything into a single app.service.ts though. The reference demos (DataGrid/AIAssistant, Form/SmartPaste, HtmlEditor/AITextEditing) each cover one AI scenario, so their logic fits comfortably in one file. This demo routes between two targets (grid/form/mixed) and executes commands against both widgets — chat-router.ts + grid-commands.ts + form-commands.ts together are 500+ lines of fairly distinct logic. Cramming all of that into one file would make it harder to read and to copy from as a reference, which matters here since it's a teaching demo. So,my proposal: merge types.ts + data.ts, and rename chat-router.ts to app.service.ts, but keep grid-commands.ts and form-commands.ts as their own files, since each is a self-contained, sizeable piece of widget-specific logic rather than an artificial layer split |
Agree, let's do it |
- Replace export function createAiIntegration() with @Injectable() class AiService { getAiIntegration() {...} } - Remove standalone - Change clearButtonOptions to a static variable - Rename the instance getter - Merge types and data
