# CLAUDE.md

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

## Project Overview

BlogWoman.de frontend - a Next.js 16 application consuming Payload CMS as a headless backend. This is a multi-tenant system where **Tenant ID 9 (slug: blogwoman)** is the target tenant.

**Tech Stack:** Next.js 16, React 19, TypeScript, Tailwind CSS 4
**Backend API:** https://cms.c2sgmbh.de/api (Production)
**Package Manager:** pnpm

## Commands

```bash
pnpm dev          # Development server (localhost:3000)
pnpm build        # Production build
pnpm start        # Start production server
pnpm lint         # ESLint
```

## Environment Variables

Create `.env.local`:

```env
NEXT_PUBLIC_PAYLOAD_URL=https://cms.c2sgmbh.de
NEXT_PUBLIC_API_URL=https://cms.c2sgmbh.de/api
NEXT_PUBLIC_TENANT_ID=9
NEXT_PUBLIC_TENANT_SLUG=blogwoman
NEXT_PUBLIC_SITE_URL=https://blogwoman.de
NEXT_PUBLIC_UMAMI_HOST=https://analytics.c2sgmbh.de
NEXT_PUBLIC_UMAMI_WEBSITE_ID=<website-id>
```

## Shared Contracts Package

This project uses `@c2s/payload-contracts` for the API client layer.

**Architecture:**
- `src/lib/cms.ts` — Shared PayloadClient instance (tenant: blogwoman, ID: 9)
- `src/lib/api.ts` — API functions powered by contracts client
- `src/lib/types.ts` — Local type aliases (simplified for component compatibility)

**Contracts Repo:** `github:complexcaresolutions/payload-contracts`

```typescript
// How the API client works (src/lib/cms.ts)
import { createPayloadClient } from "@c2s/payload-contracts/api-client"
export const cms = createPayloadClient({
  baseUrl: process.env.NEXT_PUBLIC_PAYLOAD_URL!,
  tenantId: process.env.NEXT_PUBLIC_TENANT_ID!,
})

// Usage in api.ts — tenant isolation is automatic
const page = await cms.pages.getPage("home")
const posts = await cms.posts.getPosts({ type: "blog", limit: 10 })
const nav = await cms.navigation.getNavigation("header")
```

**Type Bridge:** Local types in `types.ts` use simplified interfaces (e.g., `meta` instead of `seo`). The api.ts bridges between contracts types and local types via `as unknown as`. This will be cleaned up when components are aligned with real CMS types.

**Block Catalog:** See `node_modules/@c2s/payload-contracts/docs/BLOCK_CATALOG.md` for all 43 block definitions.

**Updating Contracts:**
```bash
pnpm update @c2s/payload-contracts
# Check for work orders in node_modules/@c2s/payload-contracts/work-orders/
```

### API Pattern - CRITICAL

**Every API call MUST include tenant filtering:**

```typescript
const PAYLOAD_URL = process.env.NEXT_PUBLIC_PAYLOAD_URL
const TENANT_ID = process.env.NEXT_PUBLIC_TENANT_ID

// CORRECT - always filter by tenant
fetch(`${PAYLOAD_URL}/api/pages?where[tenant][equals]=${TENANT_ID}&where[slug][equals]=about`)

// WRONG - will return 403 or empty results
fetch(`${PAYLOAD_URL}/api/pages?where[slug][equals]=about`)
```

### Block System

Pages from Payload contain a `layout` array of blocks. Each block has a `blockType` field:

| Block Type | Purpose |
|------------|---------|
| `hero-block` | Hero banner with image |
| `hero-slider-block` | Multi-slide hero carousel |
| `text-block` | Rich text content |
| `image-text-block` | Image + text side-by-side |
| `card-grid-block` | Card grid layout |
| `cta-block` | Call-to-action section |
| `posts-list-block` | Blog/news listing |
| `testimonials-block` | Customer testimonials |
| `faq-block` | FAQ accordion (with JSON-LD) |
| `newsletter-block` | Newsletter signup form |
| `contact-form-block` | Contact form |
| `video-block` | Video embed |
| `favorites-block` | Affiliate products (BlogWoman) |
| `series-block` | YouTube series overview (BlogWoman) |
| `series-detail-block` | Series hero (BlogWoman) |
| `video-embed-block` | Privacy-mode video embed |

**Block Renderer pattern:**
```typescript
// src/components/blocks/index.tsx
export function BlockRenderer({ blocks }) {
  return blocks.map(block => {
    const Component = blockComponents[block.blockType]
    return Component ? <Component {...block} /> : null
  })
}
```

### BlogWoman-Specific Collections

Beyond standard CMS collections (pages, posts, testimonials), BlogWoman uses:

- **favorites** - Affiliate products with categories (fashion, beauty, travel, tech, home) and badges (investment-piece, daily-driver, grfi-approved, new, bestseller)
- **series** - YouTube series with branding (logo, cover image, brand color)
