Block type "{block.blockType}" / "{block.template}" not yet implemented
);
}
return component(block);
}
```
This prevents the app from breaking if Payload has a block type your frontend doesn't support yet.
## Migration Checklist
```
PAYLOAD MIGRATION CHECKLIST:
SETUP
□ Payload CMS installed and configured
□ Types exported from Payload (@payload-types)
□ Environment variables set (API URL, tokens)
□ Test Payload API connection with curl/postman
VERIFICATION
□ Frontend types match Payload schema
□ All required fields exist in Payload
□ Example data still works (verify nothing broke)
□ BlockRenderer still routes correctly
UTILITIES
□ Created src/lib/payload.ts with helper functions
□ getPage() function works
□ getBlock() function works
□ Collection query functions (getIndustries(), etc.) work
MIGRATION
□ Updated src/app/page.tsx to use getPage()
□ Updated collection pages to use get() functions
□ Removed imports of example data
□ Verified all pages render with Payload data
□ No console errors
□ No TypeScript errors
TESTING
□ Home page loads from Payload
□ All blocks render correctly
□ Detail pages load from Payload
□ Images and media display correctly
□ Links and CTAs work
□ No 404s or missing data
□ Performance is acceptable
FALLBACKS
□ Graceful error handling for missing data
□ 404 pages for not-found content
□ Empty states for no data
□ Development mode still works with example data
```
## Keeping Development with Examples
While integrating Payload, you might want to keep development mode using example data. You can add a flag:
```typescript
// src/lib/payload.ts
const USE_EXAMPLES = process.env.NEXT_PUBLIC_USE_EXAMPLES === 'true';
export async function getPage(slug: string) {
if (USE_EXAMPLES) {
// Return example data in development
return homePageData;
}
// Query Payload in production
const response = await fetch(`${PAYLOAD_API}/api/pages?where[slug][equals]=${slug}`);
// ... etc
}
```
Then set `NEXT_PUBLIC_USE_EXAMPLES=true` in `.env.local` for local development.
## Rollback Strategy
If something goes wrong, you can quickly rollback:
```typescript
// src/lib/payload.ts
export async function getPage(slug: string) {
try {
// Query Payload
const response = await fetch(`${PAYLOAD_API}/api/pages?where[slug][equals]=${slug}`);
if (!response.ok) throw new Error('Payload error');
return await response.json();
} catch (error) {
// Fallback to example data
console.warn('Fallback to example data:', error);
return homePageData;
}
}
```
This way, if Payload is down, your site still works with example data.
## Performance Considerations
Payload queries should be efficient:
Revalidation:
```typescript
// Revalidate every 60 seconds (good for mostly-static sites)
{ next: { revalidate: 60 } }
// Revalidate every hour
{ next: { revalidate: 3600 } }
// Never revalidate (manually trigger with revalidatePath)
{ cache: 'no-store' }
```
Selective Fields:
```typescript
// Only query fields you need (not everything)
await fetch(`${PAYLOAD_API}/api/pages?select=slug,title,layout&where[slug][equals]=home`)
```
Pagination:
```typescript
// Limit results if querying collections
await fetch(`${PAYLOAD_API}/api/industries?limit=100&page=1`)
```
## Key Points to Remember
1. Your components don't change - They expect the exact type Payload provides
2. Your types guide Payload schema - Payload should match your frontend types
3. Data source changes, not the code - Just swap example data for Payload queries
4. BlockRenderer stays the same - It doesn't know or care where blocks come from
5. Fallbacks prevent broken sites - Always have a graceful fallback
## The Real Magic
This is where design-driven development truly shines. By letting design determine your data structure before you even built Payload, you ensured that when Payload was added, it matched perfectly.
No refactoring. No "we need to add a field." No "the CMS output doesn't match our frontend types." Just seamless integration.
