# KNOW-002 Implementation Summary
|
|
|
|
## Task: Entry CRUD API Endpoints
|
|
|
|
**Status:** ✅ Complete (with fixes)
|
|
|
|
## What Was Done
|
|
|
|
The Knowledge Entry CRUD API was previously implemented but had critical type safety issues that prevented compilation. This task fixed those issues and ensured the implementation meets the TypeScript strict typing requirements.
|
|
|
|
### Files Modified
|
|
|
|
1. **apps/api/src/knowledge/knowledge.controller.ts**
|
|
- Fixed authentication context access (changed from `@CurrentUser()` to `@Request()` req)
|
|
- Removed `@nestjs/swagger` decorators (package not installed)
|
|
- Properly accesses `req.user?.workspaceId` for workspace isolation
|
|
|
|
2. **apps/api/src/knowledge/knowledge.service.ts**
|
|
- Fixed Prisma type safety for nullable fields (`summary ?? null`)
|
|
- Refactored update method to conditionally build update object
|
|
- Prevents passing `undefined` to Prisma (strict type requirement)
|
|
|
|
3. **apps/api/src/knowledge/dto/create-tag.dto.ts**
|
|
- Created missing tag DTO to satisfy tags service dependency
|
|
|
|
4. **apps/api/src/knowledge/dto/update-tag.dto.ts**
|
|
- Created missing tag update DTO
|
|
|
|
### API Endpoints (Implemented)
|
|
|
|
✅ `POST /api/knowledge/entries` — Create entry
|
|
✅ `GET /api/knowledge/entries` — List entries (paginated, filterable by status/tag)
|
|
✅ `GET /api/knowledge/entries/:slug` — Get single entry by slug
|
|
✅ `PUT /api/knowledge/entries/:slug` — Update entry
|
|
✅ `DELETE /api/knowledge/entries/:slug` — Soft delete (set status to ARCHIVED)
|
|
|
|
### Features Implemented
|
|
|
|
✅ **Workspace Isolation** — Uses workspace from auth context
|
|
✅ **Slug Generation** — Automatic from title with collision handling
|
|
✅ **Input Validation** — class-validator decorators on all DTOs
|
|
✅ **Markdown Rendering** — Caches HTML on save using `marked` library
|
|
✅ **Version Control** — Creates version record on each create/update
|
|
✅ **Tag Management** — Supports tagging with auto-creation
|
|
✅ **Pagination** — Configurable page size and offset
|
|
✅ **Filtering** — By status (DRAFT/PUBLISHED/ARCHIVED) and tag
|
|
|
|
### Module Structure
|
|
|
|
```
|
|
apps/api/src/knowledge/
|
|
├── knowledge.module.ts ✅ Module definition
|
|
├── knowledge.controller.ts ✅ Entry CRUD endpoints
|
|
├── knowledge.service.ts ✅ Business logic
|
|
├── dto/
|
|
│ ├── create-entry.dto.ts ✅ Create entry validation
|
|
│ ├── update-entry.dto.ts ✅ Update entry validation
|
|
│ ├── entry-query.dto.ts ✅ List/filter query params
|
|
│ ├── create-tag.dto.ts ✅ Tag creation
|
|
│ ├── update-tag.dto.ts ✅ Tag update
|
|
│ └── index.ts ✅ Exports
|
|
└── entities/
|
|
└── knowledge-entry.entity.ts ✅ Type definitions
|
|
```
|
|
|
|
### Type Safety Improvements
|
|
|
|
1. **No `any` types** — Followed TypeScript strict guidelines
|
|
2. **Explicit return types** — All service methods properly typed
|
|
3. **Proper nullable handling** — Used `?? null` for Prisma compatibility
|
|
4. **Conditional updates** — Built update objects conditionally to avoid `undefined`
|
|
|
|
### Dependencies Added
|
|
|
|
- ✅ `marked` — Markdown to HTML conversion
|
|
- ✅ `slugify` — URL-friendly slug generation
|
|
|
|
### Integration
|
|
|
|
- ✅ Registered in `apps/api/src/app.module.ts`
|
|
- ✅ Uses existing `PrismaModule` for database access
|
|
- ✅ Uses existing `AuthGuard` for authentication
|
|
- ✅ Follows existing controller patterns (layouts, widgets)
|

fix(knowledge): fix type safety issues in entry CRUD API (KNOW-002)
|
|
|
|
- Remove @nestjs/swagger decorators (package not installed)
|
|
- Fix controller to use @Request() req for accessing workspaceId
|
|
- Fix service to properly handle nullable Prisma fields (summary)
|
|
- Fix update method to conditionally build update object
|
|
- Add missing tag DTOs to satisfy dependencies
|
|
```
|
|
|
|
## Notes
|
|
|
|
- The original implementation was done in commit `f07f044` (KNOW-003), which included both entry and tag management together
|
|
- This task addressed critical type safety issues that prevented compilation
|
|
- Followed `~/.claude/agent-guides/typescript.md` and `~/.claude/agent-guides/backend.md` strictly
|
|
- All entry-related code now compiles without type errors
|
|
|
|
## Next Steps
|
|
|
|
- Fix remaining type errors in `tags.service.ts` (out of scope for KNOW-002)
|
|
- Fix errors in `src/lib/db-context.ts` (missing `@mosaic/database` package)
|
|
- Consider adding `@nestjs/swagger` package for API documentation
|
|
- Add unit tests for entry service
|
|
- Add integration tests for entry controller
