Description

Business-logic layer that mediates between NotesListScreen and NotesRepository. It applies user-scoping, handles search filtering, and coordinates offline-aware read operations. Returns typed note collections ready for direct rendering.

Feature: Notes List

notes-service

Sources & reasoning

The priority matrix explicitly lists Notes as needed by all five organizations (all checkmarks), classified NICE, Phase 2. Phase 2 maps to v1.0 by the ordinal rule. The Notes List is the entry screen without which the Note Editor is unreachable, making it a prerequisite for the entire area.

Responsibilities

  • Fetch all notes for the authenticated user from NotesRepository
  • Filter notes by a search query string, matching against title and body content
  • Enforce user-scoping so notes from other users are never returned
  • Expose observable or async streams so the UI reacts to cache updates when offline data syncs
  • Handle errors from the repository layer and translate them into user-facing messages

Interfaces

getNotes(userId: string): Promise<Note[]>
searchNotes(userId: string, query: string): Promise<Note[]>
subscribeToNotes(userId: string, callback: (notes: Note[]) => void): Unsubscribe
