# 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.
