## Coding Conventions
- **Formatter:** Biome — 2-space indent, 100-char line width, double quotes, semicolons, trailing commas
- **Module pattern:** NestJS feature modules — each domain has `module.ts`, `service.ts`, `controller.ts`, `*.dto.ts`, `*.spec.ts`
- **API response format:** All responses wrapped in `{ success: true, data: ... }` via `TransformInterceptor`
- **Error format:** `{ success: false, error: { code, message } }` via `HttpExceptionFilter`
- **Auth:** Cookie-based via Better Auth. Skip with `@Public()` decorator. Get user with `@CurrentUser()`.
- **Roles:** `@Roles("admin")` decorator + global `RolesGuard`
- **Validation:** Zod schemas in `@sase/shared`, imported by both API and Web
- **DB naming:** snake_case columns, camelCase in TypeScript (Drizzle mapping)
- **Frontend aliases:** `@/` maps to `apps/web/src/` in Vite. `@sase/*` maps to `packages/*/src` in tsconfig.
- **Route files:** TanStack Router auto-generates `routeTree.gen.ts` — never edit manually
- **i18n:** Turkish default (`tr.json`), English available (`en.json`). Use `useTranslation()` hook → `t("key")`
## Backend Modules

## Architecture Patterns
- **Global guards order:** ThrottlerGuard → AuthGuard → RolesGuard
- **Global interceptors:** TransformInterceptor → LoggingInterceptor → TimeoutInterceptor (30s)
- **Global filters:** HttpExceptionFilter, DrizzleExceptionFilter (unique constraint → 409)
- **Vite proxy:** `/api` requests → `http://localhost:4000` in dev
### VIN Decode Fallback Chain
Corgi (offline WMI) → **PartsCatalogs API** → PL24 API → EMEX scraper → NHTSA VIN API
> Note: PartsCatalogs was added between Corgi and PL24 as it has broader VIN coverage. If multiple car matches return, the frontend prompts the user to select.
### Category Fetch Chain (VIN-based)
DB cache → PL24 → PartsCatalogs → EMEX (lazy, source-based in `getCategoryTree`)
### Catalog Browse Flow (VIN-less)
1. `GET /catalog/brands` → check user subscription access per brand
2. `GET /catalog/brands/:name/models` → PL24 `fetchVehicleList()` → stored in `catalogVehicles` table
3. `GET /catalog/vehicles/:id/categories` → PL24 `fetchMainGroups()` → stored in `categories` with `catalogVehicleId`
4. `GET /catalog/vehicles/:id/categories/:categoryId` → PL24 `fetchSubGroupsByPath()` / `fetchPartsByPath()` → stored lazily
### PL24 Catalog Architectures
- **P5_MODERN** (REST JSON API): VW Group, BMW, Mini, Mercedes, Porsche, Renault, Dacia, Alpine, Jaguar, Land Rover, Toyota, Lexus, MAN, Mitsubishi, Suzuki, etc.
- **LEGACY_PSA** (HTML scraping): Citroën, Peugeot
- **LEGACY_FORD** (HTML scraping): Ford passenger (wf0_parts) + commercial (fordt_parts)
- **LEGACY_HYUNDAI_KIA** (HTML scraping): Hyundai, Kia
- **LEGACY_NISSAN** (HTML scraping): Nissan, Infiniti
- **LEGACY_OPEL** (HTML scraping): Opel, Vauxhall
- **LEGACY_VOLVO** (HTML scraping): Volvo, Polestar
Our PL24 account (tr-903645) supports **VAG group only** for VIN-less catalog. Other brands may return errors on model listing. All P4 Legacy VIN decodes route through `PL24FordLegacyService.decodeVinForService(vin, serviceName)`.
### Caching Strategy
- Redis: VIN decode results (24h), category trees (2h for catalog browser), parts fetches (1h), translations
- HTTP Cache: brands, plans (30min `Cache-Control`)
- Sessions: Better Auth (5min Redis)
### Job Queues (BullMQ)
| Queue | Trigger | Schedule |
|-------|---------|----------|
| `EMEX_SCRAPE` | On-demand (VIN decode) | — |
| `CATALOG_PREFETCH` | After VIN decode | — (depth-limited, rate-limited, cooldown-guarded) |
| `SUBSCRIPTION_EXPIRY` | Cron | Daily 3:00 AM |
| `QUERY_CLEANUP` | Cron | Weekly Sunday 4:00 AM |
### Subscription & Access Control
- Plans have `brandCount` field: `0` = unlimited access, `N` = limited to N brands
- Brand access tracked in `userBrands` junction table (userId + subscriptionId + brandId)
- Full plan (brandCount=0) auto-adds all active brands on activation
- `BrandAccessGuard` (per-route) verifies user's subscription includes the requested brand
## Database Schema Summary
**Schema files:** `apps/api/src/database/schema/`
- `core.ts` — Main application tables
- `emex.ts` — EMEX scraper cache tables
- `pl24.ts` — PL24 catalog cache tables
- `parts-catalogs.ts` — PartsCatalogs API cache tables
- `relations.ts` — Drizzle ORM relationships
**Key tables in `core.ts`:**
- `users`, `sessions`, `accounts`, `verifications` — Better Auth managed
- `brands`, `plans` — Catalog of available brands/plans (admin-managed)
- `userSubscriptions` — status: pending/active/trial/cancelled/expired
- `userBrands` — junction table controlling brand access per subscription
- `payments` — Iyzico or EFT, status tracking
- `vehicles` — one per unique VIN, shared across users via `userVehicles`
- `userVehicles` — junction (userId + vehicleId unique), tracks lastAccessedAt
- `categories` — parent-child hierarchy; has both `vehicleId` (VIN-based) and `catalogVehicleId` (VIN-less) FKs (nullable for the other mode)
- `parts` — OEM code, quantity, hotspot index; same dual FK pattern as categories
- `schemaPics` — exploded view images + hotspots JSONB, linked to categories
- `catalogVehicles` — VIN-less catalog: one record per PL24 service vehicle (unique on source + serviceVehicleId)
- `queryLogs` — VIN decode audit trail
- `oemCodeCopies` — OEM code copy events (analytics)
- `referrals`, `passwordResetTokens`, `emexCategoryTranslations`
## Integrations
| Integration | Type | Path | Notes |
|-------------|------|------|-------|
| **Corgi** | Offline DB | `integrations/corgi/` | WMI database for brand ID |
| **PL24** | REST API + HTML scraper | `integrations/pl24/` | Multi-brand catalog; P5 (REST) + P4 Legacy (HTML). Services: `pl24.service.ts`, `pl24-ford-legacy.service.ts` |
| **PartsCatalogs** | REST API + Playwright JWT | `integrations/parts-catalogs/` | Broad VIN coverage; JWT captured via Playwright from partner sites; IP-bound via DataImpulse proxy |
| **EMEX** | Browser scraper | `integrations/emex/` | Playwright-based (emexdwc.ae), async via BullMQ |
| **VIN-API** | REST API | `integrations/vin-api/` | NHTSA VIN decoder (last-resort fallback) |

Full schema: `packages/config/src/index.ts`
## Common Gotchas
- **Frontend is Vite + TanStack Router** — NOT Next.js
- **Categories & Parts tables have dual FKs:** `vehicleId` (VIN-based, nullable) and `catalogVehicleId` (VIN-less, nullable) — always check which context you're in
- **PartsCatalogs JWT is IP-bound** via DataImpulse proxy; the auth service manages a warm pool of JWTs using Playwright
- **P4 Legacy brands have no REST API** — Ford, PSA, Hyundai/Kia, Nissan, Opel, Volvo all use HTML scraping through `PL24FordLegacyService`
- **`catalogVehicles` unique key** is `(source, serviceVehicleId)` — not by VIN (these vehicles may not have VINs)
- **`routeTree.gen.ts`** is auto-generated by TanStack Router — never edit manually
- **DrizzleExceptionFilter** catches unique constraint violations → 409 Conflict
- **File uploads:** PNG/JPG/PDF only, max 5MB (middleware in `main.ts`)
- **Env validation** uses Zod from `@sase/config` — app won't start if env vars invalid
- **Playwright (EMEX/PartsCatalogs):** `waitUntil: 'networkidle'` (not `networkidle2`); `page.context().cookies()` (not `page.cookies()`)
- **VIN decode may return candidates** if PartsCatalogs finds multiple matches — frontend shows selection modal
## ast-grep — Structural Code Search & Refactoring
ast-grep (`sg`) does AST-aware pattern matching — finds code by structure, not text. Unlike `grep`, it understands syntax so `foo( bar )` and `foo(bar)` both match the pattern `foo($X)`.
**Install:** `npm i -g @ast-grep/cli` (already installed globally)
### Pattern syntax
| Syntax | Meaning |
|--------|---------|
| `$VAR` | Matches any **single** AST node (expression, identifier, etc.) |
| `$$$ARGS` | Matches **zero or more** nodes (variadic — use for argument lists, statements) |
| Literal code | Matches exact syntax structure |
### Common commands
```bash
# Search by pattern in TypeScript files
ast-grep -p 'console.log($$$)' -l ts apps/
# Search and preview rewrite (no changes yet)
ast-grep -p '$A && $A()' --rewrite '$A?.()' -l ts apps/
# Interactive rewrite — confirm each change
ast-grep -p '$A && $A()' --rewrite '$A?.()' --interactive -l ts apps/
# Apply all rewrites without confirmation
ast-grep -p '$A && $A()' --rewrite '$A?.()' --update-all -l ts apps/
# Output matches as JSON (useful for scripting)
ast-grep -p 'useQuery($$$)' -l tsx --json apps/web/src/
# Show surrounding context lines
ast-grep -p 'db.select()' -l ts -C 3 apps/api/src/
# Limit to specific file globs
ast-grep -p '@Public()' -l ts --globs 'apps/api/src/**/*.controller.ts' .
```
### Language flags for this project
| Flag | Use for |
|------|---------|
| `-l ts` | API services, guards, modules, DTOs |
| `-l tsx` | React components, route files |
| `-l json` | i18n message files |
### Useful patterns for this codebase
```bash
# Find all @Public() decorated endpoints
ast-grep -p '@Public()' -l ts apps/api/src/
# Find all useQuery calls (TanStack Query)
ast-grep -p 'useQuery({$$$})' -l tsx apps/web/src/
# Find Drizzle inserts
ast-grep -p 'db.insert($TABLE).values($$$)' -l ts apps/api/src/
# Find all Redis cache sets
ast-grep -p 'this.redis.set($$$)' -l ts apps/api/src/
# Find t() translation calls missing a key
ast-grep -p 't($KEY)' -l tsx apps/web/src/
# Find all BullMQ queue.add() calls
ast-grep -p '$QUEUE.add($$$)' -l ts apps/api/src/jobs/
```
