|

|
||||
## Database Workflow - CRITICAL SEQUENCE ⚠️
|
||||
|
||||
When adding new database features, ALWAYS follow this exact order:
|
||||
|
||||
1. **Create/modify schema file** in `apps/web/supabase/schemas/XX-feature.sql`
|
||||
2. **Generate migration**: `pnpm --filter web supabase:db:diff -f <migration_name>`
|
||||
3. **Apply changes**: `pnpm --filter web supabase migration up` (or `pnpm supabase:web:reset` for clean rebuild)
|
||||
4. **Generate types**: `pnpm supabase:web:typegen`
|
||||
5. **Verify types exist** before using in code
|
||||
|
||||
⚠️ **NEVER skip step 2** - schema files alone don't create tables! The migration step is required to apply changes to the database.
|
||||
|
||||
**Migration vs Reset**:
|
||||
- Use `migration up` for normal development (applies only new migrations)
|
||||
- Use `reset` when you need a clean database state or have schema conflicts

||||

||||

||||

## Data Fetching Architecture
|
||||
|
||||
Makerkit uses a clear separation between data fetching and mutations:
|
||||
|
||||
### Server Components with Loaders (Reading Data)
|
||||
|
||||
**Pattern**: Use async server components that call loader functions for initial data fetching.
|
||||
|
||||
```typescript
|
||||
// Page component (apps/web/app/home/[account]/page.tsx)
|
||||
async function TeamAccountPage({ params }: Props) {
|
||||
const client = getSupabaseServerClient();
|
||||
const slug = (await params).account;
|
||||
|
||||
const [projects, workspace] = await loadProjectsPageData(client, slug);
|
||||
|
||||
return <ProjectsList projects={projects} />;
|
||||
}
|
||||
|
||||
// Loader function (_lib/server/projects-page.loader.ts)
|
||||
import 'server-only';
|
||||
|
||||
export async function loadProjectsPageData(
|
||||
client: SupabaseClient<Database>,
|
||||
slug: string,
|
||||
) {
|
||||
return Promise.all([
|
||||
loadProjects(client, slug),
|
||||
loadTeamWorkspace(slug),
|
||||
]);
|
||||
}
|
||||
|
||||
async function loadProjects(client: SupabaseClient<Database>, slug: string) {
|
||||
const { data, error } = await client.rpc('get_team_projects', {
|
||||
account_slug: slug,
|
||||
});
|
||||
|
||||
if (error) throw error;
|
||||
return data ?? [];
|
||||
}
|
||||
```
|
||||
|
||||
### Server Actions (Mutations Only)
|
||||
|
||||
**Pattern**: Use `enhanceAction` for create/update/delete operations with schema validation.
|
||||
|
||||
```typescript
|
||||
// server-actions.ts
|
||||
'use server';
|
||||
|
||||
import { enhanceAction } from '@kit/next/actions';
|
||||
|
||||
export const createProject = enhanceAction(
|
||||
async (data) => {
|
||||
const client = getSupabaseServerClient();
|
||||
const service = createProjectsService();
|
||||
|
||||
const response = await service.createProject(data);
|
||||
|
||||
if (response.error) {
|
||||
throw response.error;
|
||||
}
|
||||
|
||||
return {
|
||||
success: true,
|
||||
data: response.data,
|
||||
};
|
||||
},
|
||||
{
|
||||
schema: CreateProjectSchema,
|
||||
},
|
||||
);
|
||||
```
|
||||
|
||||
### Authorization & RLS
|
||||
|
||||
- **Server Components**: RLS automatically enforces access control
|
||||
- **Server Actions**: RLS validates permissions on mutations
|
||||
- **No manual auth checks needed** when using standard Supabase client
|
||||
- **Admin client**: Only for bypassing RLS (rare cases, requires careful manual validation)
|
||||
|
||||
## File Organization Patterns
|
||||
|
||||
### Route Structure
|
||||
```
|
||||
apps/web/app/home/[account]/
|
||||
├── page.tsx # Team dashboard
|
||||
├── members/
|
||||
│ ├── page.tsx # Members listing
|
||||
│ └── _lib/server/ # Server-side utilities
|
||||
│ └── members-page.loader.ts
|
||||
├── projects/ # New feature example
|
||||

|
||||

|
||||
│ │ └── page.tsx # Project detail page
|
||||

|
||||
│ │ ├── project-list.tsx
|
||||
│ │ └── create-project-form.tsx

│ └── project.schema.ts
|
||||
└── _components/ # Shared team account components
|
||||
└── team-account-layout-page-header.tsx
|
||||
```
|
||||
|
||||
### Naming Conventions
|
||||
- **Pages**: `page.tsx` (Next.js convention)
|
||||
- **Loaders**: `{feature}-page.loader.ts`
|
||||
- **Actions**: `{feature}-server-actions.ts`
|
||||
- **Schemas**: `{feature}.schema.ts`
|
||||
- **Components**: `kebab-case.tsx`
|
||||
|
||||
## UI Components
|
||||
|
||||
- UI Components are placed at `packages/ui`. Call MCP tool to list components to verify they exist.

|
||||
## Form Architecture
|
||||
## Delegate to Agents
|
||||
|
||||
Always organize schemas for reusability between server actions and client forms:
|
||||
|
||||
```
|
||||
_lib/
|
||||
├── schemas/
|
||||
│ └── feature.schema.ts # Shared Zod schemas
|
||||
├── server/
|
||||
│ └── server-actions.ts # Server actions import schemas
|
||||
└── client/
|
||||
└── forms.tsx # Forms import same schemas
|
||||
```
|
||||
|
||||
**Example implementation:**
|
||||
|
||||
```typescript
|
||||
// _lib/schemas/project.schema.ts
|
||||
export const CreateProjectSchema = z.object({
|
||||
name: z.string().min(1).max(255),
|
||||
description: z.string().optional(),
|
||||
});
|
||||
|
||||
// _lib/server/project.mutations.ts
|
||||
import { CreateProjectSchema } from '../schemas/project.schema';
|
||||
|
||||
export const createProjectAction = enhanceAction(
|
||||
async (data) => { /* implementation */ },
|
||||
{ schema: CreateProjectSchema }
|
||||
);
|
||||
|
||||
// _components/create-project-form.tsx
|
||||
import { CreateProjectSchema } from '../_lib/schemas/project.schema';
|
||||
|
||||
const form = useForm({
|
||||
resolver: zodResolver(CreateProjectSchema)
|
||||
});
|
||||
```
|
||||
|
||||
## Import Guidelines - ALWAYS Check These
|
||||
|
||||
**UI Components**: Always check `@kit/ui` first before external packages:
|
||||
- Toast notifications: `import { toast } from '@kit/ui/sonner'`
|
||||
- Forms: `import { Form, FormField, ... } from '@kit/ui/form'`
|
||||
- All UI components: Use MCP tool to verify: `mcp__makerkit__get_components`
|
||||
|
||||
**React Hook Form Pattern**:
|
||||
```typescript
|
||||
// ❌ WRONG - Redundant generic with resolver
|
||||
const form = useForm<FormData>({
|
||||
resolver: zodResolver(Schema)
|
||||
});
|
||||
|
||||
// ✅ CORRECT - Type inference from resolver
|
||||
const form = useForm({
|
||||
resolver: zodResolver(Schema)
|
||||
});
|
||||
```
|
||||
Please use the Task tool to delegate suitable tasks to specialized sub-agents for best handling the task at hand.
