# Phase 1 — Medicine Library
|
||||
|
||||
**Goal**: A searchable catalog of medicines with dosage and form information. Medicines are the atomic building blocks for regimens, cabinet inventory, and refill tracking.
|
||||
**Goal**: A two-level catalog of medicines. The **Medicine** level represents the generic substance you take (what regimens reference). The **MedicineProduct** level represents a specific purchasable item from a brand/manufacturer (what you buy and track prices for). Cabinet inventory tracks current quantity at the Medicine level, with an optional link back to which product it came from.
|
||||
|
||||
**Depends on**: Phase 0 (auth, households, shared types)

## Deliverables
|
||||
|
||||
1. `Medicine` MongoDB schema and full CRUD API
|
||||
2. Full-text search with filters
|
||||
3. Barcode lookup (future: integration with drug database APIs)
|
||||
4. Bulk import (CSV/JSON)
|
||||
5. Medicine library web UI (search, add, edit)
|
||||
1. `Medicine` and `MedicineProduct` MongoDB schemas with full CRUD APIs
|
||||
2. Full-text search with category/form filters
|
||||
3. Cascade delete protection (cannot delete medicine with linked products)
|
||||
4. Medicine library web UI (search, filter, add, edit, delete -- both levels)

### Medicine Schema

### Medicine Schema (Generic Level)

|
||||
- `packages/api/src/modules/medicines/medicines.repository.ts`

|
||||
- [x] `packages/api/src/modules/medicines/medicines.repository.ts`
|
||||
- [x] `MedicinesRepository` with:

|
||||
- `MedicinesRoutes` with Fastify route plugin registering all endpoints
|
||||
- Register Awilix dependencies via `fp()` plugin
|
||||
- [x] `packages/api/src/modules/medicine-products/medicine-products.repository.ts`
|
||||
- [x] `MedicineProductsRepository` with:
|
||||
- `findByMedicine(householdId, medicineId, query)` -- paginated
|
||||
- `findById(id, householdId)`
|
||||
- `countByMedicineId(medicineId)` -- for cascade delete check
|
||||
- `create(data)`
|
||||
- `update(id, householdId, data)`
|
||||
- `softDelete(id, householdId)`
|
||||
|
||||
### 1.4 — Barcode Lookup
|
||||
### 1.4 -- Services & Routes
|
||||
|
||||
- `BarcodeLookupService`:
|
||||
- First check local DB for matching barcode
|
||||
- Placeholder for external drug database API integration (manual entry fallback)
|
||||
- Cache results in local DB with `source: 'barcode_lookup'`
|
||||
- [x] `MedicinesService` with business logic:
|
||||
- Dedup check on create (same name + strength + strengthUnit + form within household)
|
||||
- Cascade: when deleting a medicine, check for linked products and block if any exist
|
||||
- [x] `MedicineProductsService` with business logic:
|
||||
- Validate medicineId exists on create
|
||||
- Denormalize medicineName
|
||||
- [x] Route plugins for both modules, registered via `fp()`
|
||||
|
||||
### 1.5 — Import Endpoint
|
||||
### 1.5 -- Web UI: Medicine Library
|
||||
|
||||
- `POST /medicines/import` accepts multipart CSV or JSON file
|
||||
- Validate each row against `CreateMedicineSchema`
|
||||
- Return summary: `{ imported: N, skipped: M, errors: [...] }`
|
||||
- CSV column mapping: `name, genericName, brand, barcode, form, strength, strengthUnit, category, activeIngredient, manufacturer`
|
||||
|
||||
### 1.6 — Web UI: Medicine Library
|
||||
|
||||
- `/medicines` page:
|
||||
- Search bar with debounced full-text search
|
||||
- [x] `/medicines` page:
|
||||
- Search bar with text search
|
||||
- Category and form filter dropdowns
|
||||
- Tag filter chips
|
||||
- Medicine grid/list view (toggle)
|
||||
- Each medicine card shows: name, strength + unit, form, brand, category badge
|
||||
- Add/Edit medicine modal:
|
||||
- Form fields for all medicine properties
|
||||
- Barcode field with "Lookup" button
|
||||
- Import dialog: file upload with preview and error display
|
||||
- Medicine list view
|
||||
- Each medicine card shows: name, strength + unit, form, category badge
|
||||
- Click a medicine to see its detail page with products
|
||||
- [x] Add/Edit medicine form
|
||||
- [x] Add/Edit product form (nested under a medicine detail page)
|
||||
- Brand, manufacturer, package size, concentration (vials only)
|
||||
- [x] Delete with confirmation (blocked if products exist)
|
||||
|
||||
---
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- [ ] Can create, read, update, delete medicines via API
|
||||
- [ ] Full-text search returns relevant results
|
||||
- [ ] Barcode lookup checks local DB first
|
||||
- [ ] Bulk import processes a CSV with 100+ medicines
|
||||
- [ ] Web UI allows searching, filtering, adding, and editing medicines
|
||||
- [ ] All medicine queries are scoped to `householdId`
|
||||
- [ ] Dedup check prevents creating duplicate medicines (same name + strength + form)
|
||||
|
||||
- [x] Can create, read, update, delete medicines (generic level) via API
|
||||
- [x] Can create, read, update, delete medicine products (purchasable level) via API
|
||||
- [x] Medicine products are correctly linked to their parent medicine
|
||||
- [x] Full-text search returns relevant results
|
||||
- [x] Category and form filters work on the medicines list
|
||||
- [x] Cascade delete check prevents deleting medicines with linked products
|
||||
- [x] Web UI shows two-level hierarchy: medicines with nested products
|
||||
- [x] All queries are scoped to `householdId`
|
||||
- [x] Dedup check prevents creating duplicate medicines (same name + strength + unit + form)
|
||||
- [x] Vial products support concentration + concentration unit fields

||||
## Estimated Effort
|
||||
|
||||
Medium. Straightforward CRUD with search, following the same patterns established in Phase 0.
|
||||
Medium. Two related CRUD modules with search. The two-level structure adds a bit of complexity over a flat model but keeps the domain clean.

### 2.4 — Expiry Check Job
|
||||
### 2.4 — Web UI: Medicine Cabinet
|
||||
|
||||
- Scheduled job (daily at 6 AM, configurable):
|
||||
1. Query all active cabinet items with `expirationDate <= today`
|
||||
2. Update status to `expired`
|
||||
3. Create in-app notifications for expired items
|
||||
4. Query items expiring within 7 days, create warning notifications
|
||||
|
||||
### 2.5 — Web UI: Medicine Cabinet
|
||||
|
||||
- `/cabinet` page:
|
||||
- `/medicines/cabinet` page:
|
||||
- **Summary view** (default): aggregated per medicine
|
||||
- Medicine name, total quantity, earliest expiry, low stock indicator
|
||||
- Medicine name, total quantity, earliest expiry
|
||||
- Expand to see individual items (bottles/boxes)
|
||||
- **Detail view**: all individual cabinet items
|
||||
- Each item shows: medicine name, quantity, expiry date, status badge
|
||||
- Color-coded expiry: green (>30 days), yellow (7-30 days), red (<7 days), grey (expired)
|
||||
- Low stock badge on medicines below threshold
|
||||
- Quick actions: adjust quantity (+/-), discard
|
||||
- "Add to Cabinet" button -> modal:
|
||||
- Medicine autocomplete (from library)
|
||||
- Quantity + unit
|
||||
- Expiration date (optional)
|
||||
- Lot number (optional)
|
||||
- Purchase date, price, store (optional)
|
||||
- `/cabinet/alerts` or notification panel:
|
||||
- Expiring soon items
|
||||
- Low stock warnings
|
||||
- **Detail view**: all individual cabinet items with status filter
|
||||
- Each item shows: quantity, unit, expiry date, status badge
|
||||
- Color-coded expiry: green (>30 days), yellow (7-30 days), red (<7 days), bold red (expired)
|
||||
- Quick actions: adjust quantity (+/-), delete
|
||||
- "Add to Cabinet" form with medicine search/select
|
||||
- `/medicines/[id]` detail page:
|
||||
- Inventory section showing cabinet items for that medicine
|
||||
- Adjust and delete actions inline
|
||||

## Acceptance Criteria
|
||||
|
||||
- [ ] Can add items to cabinet linked to medicines
|
||||
- [ ] Aggregate summary shows total quantity per medicine
|
||||
- [ ] Quantity adjustments are atomic and floor at 0
|
||||
- [ ] Items auto-transition to `depleted` when quantity reaches 0
|
||||
- [ ] Items auto-transition to `expired` when past expiration date
|
||||
- [ ] Expiring-soon endpoint returns items within N days
|
||||
- [ ] Low-stock endpoint compares against configurable thresholds
|
||||
- [ ] FEFO deduction draws from earliest-expiring items first
|
||||
- [ ] Web UI shows color-coded expiry indicators
|
||||
- [ ] All cabinet queries are scoped to `householdId`
|
||||
|
||||
---
|
||||
|
||||
## Estimated Effort
|
||||
|
||||
Medium. CRUD with aggregation pipeline, FEFO logic, and scheduled expiry job. Simpler than food pantry tracking (no freshness estimation).
|
||||
- [x] Can add items to cabinet linked to medicines
|
||||
- [x] Aggregate summary shows total quantity per medicine
|
||||
