This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Dev Setup

cp .env.example .env.local        # fill in secrets (lives at repo root)
ln -s ../../.env.local apps/web/.env.local   # Next.js reads from apps/web/, not root
docker compose -f docker/compose.yml up -d   # start postgres, redis, minio
pnpm install
pnpm db:generate                  # generate migrations from schema (first time)
pnpm db:migrate                   # apply migrations
pnpm db:seed                      # seed tier definitions
pnpm dev                          # start Next.js on :3000

MinIO console: http://localhost:9001 (minioadmin / minioadmin)

Key Commands

pnpm dev                   # run web app
pnpm build                 # production build
pnpm lint                  # lint all packages
pnpm typecheck             # type-check all packages

pnpm db:generate           # generate Drizzle migration from schema changes
pnpm db:migrate            # apply migrations
pnpm db:seed               # seed tier definitions
pnpm db:studio             # open Drizzle Studio

Architecture

Monorepo (pnpm workspaces):

• apps/web — Next.js 15 App Router app (@epicure/web)
• packages/db — Drizzle ORM schema + client (@epicure/db)
• packages/api-types — Zod schemas, single source of truth for API types + OpenAPI (@epicure/api-types)

Route groups in apps/web/app/:

• (auth)/ — login, signup, verify-email (no auth required)
• (app)/ — main app shell with nav (auth required)
• admin/ — admin-only, role checked in layout server component
• api/v1/ — REST API endpoints
• api/auth/[...all]/ — Better Auth handler

Auth: Better Auth with Drizzle adapter. Server: lib/auth/server.ts. Client: lib/auth/client.ts. Middleware at middleware.ts guards all routes.

DB: Drizzle ORM on Postgres. Schema in packages/db/src/schema/ split by domain: users, recipes, social, meal-planning, tiers. Import from @epicure/db.

AI (Phase 3): Vercel AI SDK provider factory in apps/web/lib/ai/. All AI outputs use generateObject + Zod schemas — no free-text parsing.

Storage: S3-compatible via STORAGE_* env vars. MinIO locally, any S3-compatible provider in prod.

Tier limits: lib/tiers.ts exports checkTierLimit(userId, tier, key) — call before recipe create and AI calls. Throws TierLimitError on breach.

Adding a shadcn/ui Component

cd apps/web && pnpm dlx shadcn@latest add <component-name>

Schema Changes

1. Edit packages/db/src/schema/*.ts
2. pnpm db:generate — creates migration file
3. pnpm db:migrate — applies it
4. Update corresponding Zod schemas in packages/api-types/src/

Environment Variables

See .env.example. Required for dev: DATABASE_URL, BETTER_AUTH_SECRET, BETTER_AUTH_URL. AI keys optional until Phase 3.
