# Handoff Report — Milestone 2: Backend & DB
|
|
|
|
## 1. Observation
|
|
We observed the database schema defined in `apps/backend/prisma/schema.prisma` and determined that `Menu` and `MenuItem` models required new fields.
|
|
We executed the database migration using the following command inside `apps/backend/`:
|
|
```bash
|
|
bunx prisma migrate dev --name add_menu_image_fields
|
|
```
|
|
This successfully generated the migration file `apps/backend/prisma/migrations/20260629012157_add_menu_image_fields/migration.sql` with content:
|
|
```sql
|
|
-- AlterTable
|
|
ALTER TABLE "Menu" ADD COLUMN "rootImage" TEXT;
|
|
|
|
-- AlterTable
|
|
ALTER TABLE "MenuItem" ADD COLUMN "columnImage" TEXT,
|
|
ADD COLUMN "hoverImage" TEXT;
|
|
```
|
|
The Prisma client was successfully regenerated with `bunx prisma generate`.
|
|
|
|
We checked packages/types/index.ts and modified `Menu` and `MenuItem` interfaces:
|
|
- `MenuItem` received optional `columnImage?: string | null` and `hoverImage?: string | null`.
|
|
- `Menu` received optional `rootImage?: string | null`.
|
|
|
|
We checked and modified routes in `apps/backend/src/routes/menus.ts` to include parser destructuring, TypeBox validation, and transaction mappings.
|
|
We checked and updated `apps/mcp-server/menu-tools.ts` helper function `validateMenuItems` to validate `columnImage` and `hoverImage`.
|
|
We updated `apps/mcp-server/menu-toolkit.ts` to add schema validation parameters, pass parameters to backend payload, and display `rootImage` in dryRun preview and response.
|
|
|
|
We verified build/typecheck compilation for all affected projects:
|
|
- `apps/mcp-server` typecheck command `bun run check` completed with exit code 0.
|
|
- `apps/admin` typecheck command `bunx tsc -b` completed with exit code 0.
|
|
- `apps/spa` typecheck command `bunx tsc -b` completed with exit code 0.
|
|
- `apps/website` typecheck command `bunx tsc --noEmit` completed with exit code 0.
|
|
|
|
## 2. Logic Chain
|
|
- Adding `rootImage` to the `Menu` model and `columnImage` / `hoverImage` to the `MenuItem` model in `schema.prisma` enables database storage for Premium Mega Menu image assets.
|
|
- Running `prisma migrate dev` propagates these schema changes to the local PostgreSQL database and generates client definitions so TypeScript can typecheck the new columns.
|
|
- Updating `packages/types/index.ts` ensures that frontend and backend share consistent TypeScript interfaces for Menu/MenuItem properties.
|
|
- Updating routes in `apps/backend/src/routes/menus.ts` allows Elysia validator `t` to accept the new image properties in GET, POST, and PUT payloads and write them to database records via Prisma.
|
|
- Updating `apps/mcp-server/menu-tools.ts` and `apps/mcp-server/menu-toolkit.ts` exposes the fields to MCP `upsert_menu` tool and performs dryRun rendering safely.
|
|
- Successful TypeScript compilation across `mcp-server`, `admin`, `spa`, and `website` proves type safety and consistency.
|
|
|
|
## 3. Caveats
|
|
- No caveats. The database migration was executed successfully on local DB, client regenerated, type-checked, and routes were modified cleanly.
|
|
|
|
## 4. Conclusion
|
|
The backend and database changes for the Premium Mega Menu have been successfully implemented, migrated, and verified across all workspaces.
|
|
|
|
## 5. Verification Method
|
|
To independently verify the implementation:
|
|
1. Run Prisma client validation to make sure the client matches the schema:
|
|
```bash
|
|
cd apps/backend/
|
|
bunx prisma validate
|
|
```
|
|
2. Verify the TypeScript compiles successfully:
|
|
```bash
|
|
cd apps/mcp-server/ && bun run check
|
|
cd apps/admin/ && bunx tsc -b
|
|
cd apps/spa/ && bunx tsc -b
|
|
cd apps/website/ && bunx tsc --noEmit
|
|
```
|
|
3. Inspect `apps/backend/prisma/migrations/20260629012157_add_menu_image_fields/migration.sql` and verify the columns were created.
