Stroberi Development

Overview

Stroberi is a local-first expense tracker (Expo + React Native + WatermelonDB). Keep privacy guarantees, conversion correctness, and schema safety intact while implementing changes.

Working Checklist

1. Confirm the change scope and touched modules (app, components, features, database, hooks, lib).
2. Reuse existing patterns (Tamagui components, sheet flows, hook-driven state) before introducing new abstractions.
3. Keep business logic in features/, database/actions/, or lib/ instead of large screen/components blocks.
4. For schema-impacting work, update database/schema.ts, database/migrations.ts, and affected models together.
5. Run validation before completion:
   • yarn lint
   • yarn check:types
   • Related tests for touched logic (yarn test --watchAll=false if needed)

Core Rules

• Use yarn for package/script operations.
• Preserve local-only data behavior for transactions.
• Keep feature-flag compatibility for:
  • budgeting_enabled
  • trips_enabled
  • advanced_analytics_enabled
• Keep currency conversion and allowMissingRate behavior stable when editing create/update/import flows.

When Not to Use

• Pure release/version bump tasks: use stroberi-release.
• Non-code documentation-only tasks that do not affect workflow behavior.
