refactor(topics): 멀티 에이전트용 지식 재편 — _Common(공통 기본기) + Domain_* 구조
에이전트 8종(대화형/프로그래머 C·S/디자이너/설계자/기획자/QA/PD/PM)에게 [공통 기본 능력 + 롤별 Specialty] 2층으로 지식을 주입하기 위한 재분류. 문서 내용·포맷은 무수정, 폴더 이동만 (6,372개 문서 수 보존 확인). - Topic_Programming → Domain_Programming (내부 구조 보존) - Topic_Graphic → Domain_Design - Topic_Business → Domain_Product - Topic_General → Domain_General - _Common 신설: Math(구 Topic_Math_Specialty), Reasoning(구 General/From_Thinking & Reasoning), Reasoning_Creativity(구 General/From_창의성), Communication(Poetic_Blog_Writing + From_writing) - 타 도메인의 From_* 폴더는 유지 (출처 표기일 뿐, 이미 도메인에 맞게 분류된 문서) - 빈 폴더 정리 (memory/procedures) - 에이전트→폴더 매핑은 workspace의 .astra/agent-knowledge-map.json (9개 에이전트) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# SaaS 플랫폼 및 인터랙티브 대시보드 개발
|
||||
|
||||
## 매 한 줄
|
||||
> **"매 SaaS dashboard는 multi-tenant + RBAC + real-time data viz 의 합"**. 2026 기준 Next.js 15 (App Router, RSC) + Postgres (RLS) + Drizzle/Prisma + TanStack Query/Table + Tremor/Recharts 가 standard stack. 매 핵심 challenge 는 tenant isolation, query 성능, real-time sync.
|
||||
|
||||
## 매 핵심
|
||||
|
||||
### 매 Tenant 모델
|
||||
- **Pool model**: 단일 DB, `tenant_id` column + Postgres RLS
|
||||
- **Silo model**: tenant 마다 별도 DB / schema
|
||||
- **Bridge model**: shared services + tenant-specific schema
|
||||
|
||||
### 매 Dashboard 구성요소
|
||||
- KPI cards (metric + delta + sparkline)
|
||||
- Time-series charts (line, area)
|
||||
- Distribution (bar, pie, treemap)
|
||||
- Table (sortable, filterable, paginated)
|
||||
- Filters (date range, segment, dimension)
|
||||
|
||||
### 매 응용
|
||||
1. B2B analytics (Mixpanel-like).
|
||||
2. Operations dashboard (Datadog-like).
|
||||
3. Admin console (Stripe-like).
|
||||
4. Customer portal.
|
||||
|
||||
## 💻 패턴
|
||||
|
||||
### Postgres RLS for tenant isolation
|
||||
```sql
|
||||
ALTER TABLE invoices ENABLE ROW LEVEL SECURITY;
|
||||
|
||||
CREATE POLICY tenant_isolation ON invoices
|
||||
USING (tenant_id = current_setting('app.tenant_id')::uuid);
|
||||
|
||||
-- 매 connection per request:
|
||||
-- SET app.tenant_id = '...';
|
||||
```
|
||||
|
||||
### Drizzle multi-tenant query
|
||||
```typescript
|
||||
import { drizzle } from "drizzle-orm/node-postgres";
|
||||
import { eq } from "drizzle-orm";
|
||||
import { invoices } from "./schema";
|
||||
|
||||
export async function getInvoices(db: typeof drizzle, tenantId: string) {
|
||||
await db.execute(`SET app.tenant_id = '${tenantId}'`);
|
||||
return db.select().from(invoices);
|
||||
}
|
||||
```
|
||||
|
||||
### Next.js 15 RSC dashboard page
|
||||
```tsx
|
||||
// app/(dashboard)/metrics/page.tsx
|
||||
import { Suspense } from "react";
|
||||
import { KpiCard } from "@/components/kpi-card";
|
||||
import { RevenueChart } from "@/components/revenue-chart";
|
||||
import { getMetrics } from "@/lib/data";
|
||||
|
||||
export default async function Page({
|
||||
searchParams,
|
||||
}: { searchParams: Promise<{ range?: string }> }) {
|
||||
const { range = "30d" } = await searchParams;
|
||||
return (
|
||||
<div className="grid grid-cols-3 gap-4">
|
||||
<Suspense fallback={<KpiCard.Skeleton />}>
|
||||
<KpiPanel range={range} />
|
||||
</Suspense>
|
||||
<Suspense fallback={<RevenueChart.Skeleton />}>
|
||||
<RevenuePanel range={range} />
|
||||
</Suspense>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
async function KpiPanel({ range }: { range: string }) {
|
||||
const m = await getMetrics(range);
|
||||
return <KpiCard label="MRR" value={m.mrr} delta={m.mrrDelta} />;
|
||||
}
|
||||
```
|
||||
|
||||
### TanStack Query with WebSocket invalidation
|
||||
```typescript
|
||||
import { useQuery, useQueryClient } from "@tanstack/react-query";
|
||||
import { useEffect } from "react";
|
||||
|
||||
export function useLiveMetrics(tenantId: string) {
|
||||
const qc = useQueryClient();
|
||||
const q = useQuery({
|
||||
queryKey: ["metrics", tenantId],
|
||||
queryFn: () => fetch(`/api/metrics`).then((r) => r.json()),
|
||||
staleTime: 30_000,
|
||||
});
|
||||
|
||||
useEffect(() => {
|
||||
const ws = new WebSocket(`/ws/${tenantId}`);
|
||||
ws.onmessage = (e) => {
|
||||
const ev = JSON.parse(e.data);
|
||||
if (ev.type === "metrics.updated") {
|
||||
qc.invalidateQueries({ queryKey: ["metrics", tenantId] });
|
||||
}
|
||||
};
|
||||
return () => ws.close();
|
||||
}, [tenantId, qc]);
|
||||
|
||||
return q;
|
||||
}
|
||||
```
|
||||
|
||||
### Tremor KPI card
|
||||
```tsx
|
||||
import { Card, Metric, Text, Flex, BadgeDelta } from "@tremor/react";
|
||||
|
||||
export function KpiCard({
|
||||
label, value, delta,
|
||||
}: { label: string; value: string; delta: number }) {
|
||||
return (
|
||||
<Card>
|
||||
<Flex justifyContent="between" alignItems="start">
|
||||
<div>
|
||||
<Text>{label}</Text>
|
||||
<Metric>{value}</Metric>
|
||||
</div>
|
||||
<BadgeDelta deltaType={delta >= 0 ? "increase" : "decrease"}>
|
||||
{delta >= 0 ? "+" : ""}{delta}%
|
||||
</BadgeDelta>
|
||||
</Flex>
|
||||
</Card>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### TanStack Table virtualized
|
||||
```tsx
|
||||
import { useReactTable, getCoreRowModel, flexRender } from "@tanstack/react-table";
|
||||
import { useVirtualizer } from "@tanstack/react-virtual";
|
||||
import { useRef } from "react";
|
||||
|
||||
export function DataTable<T>({ data, columns }: { data: T[]; columns: any }) {
|
||||
const table = useReactTable({ data, columns, getCoreRowModel: getCoreRowModel() });
|
||||
const ref = useRef<HTMLDivElement>(null);
|
||||
const v = useVirtualizer({
|
||||
count: table.getRowModel().rows.length,
|
||||
getScrollElement: () => ref.current,
|
||||
estimateSize: () => 40,
|
||||
});
|
||||
|
||||
return (
|
||||
<div ref={ref} className="h-[600px] overflow-auto">
|
||||
<div style={{ height: v.getTotalSize() }}>
|
||||
{v.getVirtualItems().map((vi) => {
|
||||
const row = table.getRowModel().rows[vi.index];
|
||||
return (
|
||||
<div key={row.id} style={{ transform: `translateY(${vi.start}px)` }}>
|
||||
{row.getVisibleCells().map((c) =>
|
||||
flexRender(c.column.columnDef.cell, c.getContext())
|
||||
)}
|
||||
</div>
|
||||
);
|
||||
})}
|
||||
</div>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### RBAC middleware
|
||||
```typescript
|
||||
// lib/rbac.ts
|
||||
type Role = "owner" | "admin" | "member" | "viewer";
|
||||
const PERMS: Record<Role, Set<string>> = {
|
||||
owner: new Set(["*"]),
|
||||
admin: new Set(["billing.read", "users.write", "metrics.read"]),
|
||||
member: new Set(["metrics.read", "users.read"]),
|
||||
viewer: new Set(["metrics.read"]),
|
||||
};
|
||||
|
||||
export function can(role: Role, action: string): boolean {
|
||||
const p = PERMS[role];
|
||||
return p.has("*") || p.has(action);
|
||||
}
|
||||
```
|
||||
|
||||
### Server Action with audit log
|
||||
```typescript
|
||||
"use server";
|
||||
import { auth } from "@/lib/auth";
|
||||
import { db } from "@/lib/db";
|
||||
import { auditLog, users } from "@/lib/db/schema";
|
||||
|
||||
export async function inviteUser(email: string) {
|
||||
const session = await auth();
|
||||
if (!session) throw new Error("unauth");
|
||||
await db.insert(users).values({ email, tenantId: session.tenantId });
|
||||
await db.insert(auditLog).values({
|
||||
actor: session.userId,
|
||||
action: "user.invited",
|
||||
target: email,
|
||||
tenantId: session.tenantId,
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
## 매 결정 기준
|
||||
| 상황 | Approach |
|
||||
|---|---|
|
||||
| <100 tenants | Pool + RLS |
|
||||
| Compliance heavy (HIPAA) | Silo (per-tenant DB) |
|
||||
| Heavy analytics | Pool + ClickHouse for aggregates |
|
||||
| Real-time updates | WebSocket + TanStack Query invalidation |
|
||||
| Charts | Tremor (out-of-box) / Recharts (custom) |
|
||||
|
||||
**기본값**: Next.js 15 RSC + Postgres+RLS + Drizzle + TanStack Query + Tremor.
|
||||
|
||||
## 🔗 Graph
|
||||
- 변형: [[Embedded Analytics]]
|
||||
- Adjacent: [[RBAC]] · [[Tremor]]
|
||||
|
||||
## 🤖 LLM 활용
|
||||
**언제**: B2B analytics product, ops dashboard, admin console scaffold. 매 multi-tenant 모델 결정.
|
||||
**언제 X**: Internal-only single-tenant tool (overkill). 매 marketing site.
|
||||
|
||||
## ❌ 안티패턴
|
||||
- **No tenant isolation**: 매 RLS 또는 query-level scope 필수.
|
||||
- **Client-only filters**: 100k row 를 client 로 보내고 filter → 매 server-side filter+pagination.
|
||||
- **Polling instead of WS**: 5s interval polling → WebSocket / SSE.
|
||||
- **Charting heavyweight**: Plotly for simple line chart → 매 Tremor / Recharts.
|
||||
- **Forgotten audit log**: 매 sensitive action 은 immutable log.
|
||||
|
||||
## 🧪 검증 / 중복
|
||||
- Verified (Vercel SaaS templates, Stripe / Linear engineering blogs, 2026).
|
||||
- 신뢰도 A.
