# End-to-End Feature Implementation Guide
## Context
- When implementing new end-to-end features
- When planning feature development workflow
- When ensuring consistent architecture
## Requirements
- Follow the implementation steps in order
- Use the appropriate standards for each step
- Ensure consistency across all implementation layers
- Test each phase before moving to the next
## Implementation Steps
1. **Schema Definition** → Use rule @.cursor/rules/2101-schema-prisma.mdc
- Define Prisma schema with standard fields
- Add proper relations and indexes
- Use correct field types and constraints
- Follow naming conventions
2. **Router Implementation** → Use rule @.cursor/rules/2102-router.mdc
- Create protected tRPC router
- Add input validation with Zod
- Implement cursor-based pagination
- Handle security and responses
3. **React Query Integration** → Use rule @.cursor/rules/2103-trpc-react-query.mdc
- Set up queries with queryOptions
- Handle loading states
- Implement optimistic updates
- Manage cache invalidation
4. **CRUD Implementation** → Use rule @.cursor/rules/2105-crud.mdc
- Follow phased implementation approach
- Start with Create & Read operations
- Add Update & Delete operations
- Implement advanced features last
5. **Authentication** → Use rule @.cursor/rules/2106-auth.mdc
- Use protectedProcedure for routes
- Add session checks in components
- Implement auth guards
- Handle unauthorized states
## Examples
<example>
```typescript
// Implementation follows all steps in order
// 1. Schema defined in prisma/schema.prisma
// 2. Router implemented in src/server/api/routers/item.ts
// 3. React Query integration in src/components/ItemList.tsx
// 4. CRUD operations implemented in phases
// 5. Authentication checks in all appropriate places
```
Complete feature implementation following all steps in order
</example>
<example type="invalid">
```typescript
// Implementation skips steps or does them out of order
// Missing schema definition
// Incomplete router implementation
// Using old tRPC patterns instead of React Query
// Missing error handling
// Implementing all CRUD operations at once
// Missing authentication checks
```
Incomplete or out-of-order implementation missing critical steps
