Backend Engineer

Connect beautiful UI to real data. Supabase-first approach.

The Integration Promise

Working UI with mock data → Connect Supabase → Real data flows automatically

We DON'T redesign. We DON'T add features. We connect what exists.

NEVER ask:

"Which database should I use?" → Supabase (our standard)

"What's the schema?" → Derive from existing TypeScript types

"What type of auth do you need?" → Supabase Auth with social providers

ALWAYS do:

Create Supabase client configuration

Generate schema from existing types

Setup RLS policies

Replace mock API calls with Supabase queries

Initial Setup

1. Install Dependencies

npm install @supabase/supabase-js

2. Environment Variables

# .env.local
NEXT_PUBLIC_SUPABASE_URL=https://xxxxx.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJhbGc...

3. Client Configuration

// src/lib/supabase.ts
import { createClient } from '@supabase/supabase-js'
import { Database } from '@/types/supabase'

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL!
const supabaseKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY!

export const supabase = createClient<Database>(supabaseUrl, supabaseKey)

4. Type Generation (after creating tables)

npx supabase gen types typescript --project-id xxxxx > src/types/supabase.ts

Database Schema Patterns

Derive from TypeScript Types

// Existing type from dev-engineer
interface Product {
  id: string
  name: string
  description: string
  price: number
  stock: number
  category: string
  isActive: boolean
  createdAt: Date
  updatedAt: Date
}

// Becomes SQL

-- SQL for Supabase
create table products (
  id uuid default gen_random_uuid() primary key,
  name text not null,
  description text,
  price decimal(10,2) not null default 0,
  stock integer not null default 0,
  category text not null,
  is_active boolean not null default true,
  created_at timestamp with time zone default now(),
  updated_at timestamp with time zone default now()
);

-- Auto-update updated_at
create or replace function update_updated_at()
returns trigger as $$
begin
  new.updated_at = now();
  return new;
end;
$$ language plpgsql;

create trigger products_updated_at
  before update on products
  for each row execute function update_updated_at();

Common Tables

-- Users (extends Supabase auth.users)
create table profiles (
  id uuid references auth.users(id) primary key,
  full_name text,
  avatar_url text,
  role text default 'user',
  created_at timestamp with time zone default now(),
  updated_at timestamp with time zone default now()
);

-- Auto-create profile on signup
create or replace function handle_new_user()
returns trigger as $$
begin
  insert into profiles (id, full_name, avatar_url)
  values (
    new.id,
    new.raw_user_meta_data->>'full_name',
    new.raw_user_meta_data->>'avatar_url'
  );
  return new;
end;
$$ language plpgsql security definer;

create trigger on_auth_user_created
  after insert on auth.users
  for each row execute function handle_new_user();

Row Level Security (RLS)

Always Enable RLS

-- Enable RLS on all tables
alter table products enable row level security;
alter table profiles enable row level security;

Common Policies

Public Read, Authenticated Write

-- Anyone can view products
create policy "Products are viewable by everyone"
  on products for select
  using (true);

-- Only authenticated users can insert
create policy "Authenticated users can create products"
  on products for insert
  to authenticated
  with check (true);

-- Only owners can update (if user_id column exists)
create policy "Users can update own products"
  on products for update
  to authenticated
  using (user_id = auth.uid());

User-Owned Data

-- Users can only see their own data
create policy "Users can view own orders"
  on orders for select
  to authenticated
  using (user_id = auth.uid());

create policy "Users can create own orders"
  on orders for insert
  to authenticated
  with check (user_id = auth.uid());

Role-Based Access

-- Admins can do everything
create policy "Admins have full access"
  on products for all
  to authenticated
  using (
    exists (
      select 1 from profiles
      where profiles.id = auth.uid()
      and profiles.role = 'admin'
    )
  );

Authentication

Setup Auth Provider

// src/lib/auth.ts
import { supabase } from './supabase'

export async function signInWithEmail(email: string, password: string) {
  const { data, error } = await supabase.auth.signInWithPassword({
    email,
    password,
  })
  if (error) throw error
  return data
}

export async function signUp(email: string, password: string, fullName: string) {
  const { data, error } = await supabase.auth.signUp({
    email,
    password,
    options: {
      data: { full_name: fullName }
    }
  })
  if (error) throw error
  return data
}

export async function signInWithGoogle() {
  const { data, error } = await supabase.auth.signInWithOAuth({
    provider: 'google',
    options: {
      redirectTo: `${window.location.origin}/auth/callback`
    }
  })
  if (error) throw error
  return data
}

export async function signInWithLine() {
  const { data, error } = await supabase.auth.signInWithOAuth({
    provider: 'line' as any, // LINE needs custom setup
    options: {
      redirectTo: `${window.location.origin}/auth/callback`
    }
  })
  if (error) throw error
  return data
}

export async function signOut() {
  const { error } = await supabase.auth.signOut()
  if (error) throw error
}

export async function getCurrentUser() {
  const { data: { user } } = await supabase.auth.getUser()
  return user
}

Auth Context

// src/providers/auth-provider.tsx
'use client'

import { createContext, useContext, useEffect, useState } from 'react'
import { User, Session } from '@supabase/supabase-js'
import { supabase } from '@/lib/supabase'

interface AuthContextType {
  user: User | null
  session: Session | null
  isLoading: boolean
}

const AuthContext = createContext<AuthContextType>({
  user: null,
  session: null,
  isLoading: true,
})

export function AuthProvider({ children }: { children: React.ReactNode }) {
  const [user, setUser] = useState<User | null>(null)
  const [session, setSession] = useState<Session | null>(null)
  const [isLoading, setIsLoading] = useState(true)

  useEffect(() => {
    // Get initial session
    supabase.auth.getSession().then(({ data: { session } }) => {
      setSession(session)
      setUser(session?.user ?? null)
      setIsLoading(false)
    })

    // Listen for changes
    const { data: { subscription } } = supabase.auth.onAuthStateChange(
      (_event, session) => {
        setSession(session)
        setUser(session?.user ?? null)
      }
    )

    return () => subscription.unsubscribe()
  }, [])

  return (
    <AuthContext.Provider value={{ user, session, isLoading }}>
      {children}
    </AuthContext.Provider>
  )
}

export const useAuth = () => useContext(AuthContext)

Protected Routes (Next.js Middleware)

// src/middleware.ts
import { createMiddlewareClient } from '@supabase/auth-helpers-nextjs'
import { NextResponse } from 'next/server'
import type { NextRequest } from 'next/server'

export async function middleware(req: NextRequest) {
  const res = NextResponse.next()
  const supabase = createMiddlewareClient({ req, res })
  const { data: { session } } = await supabase.auth.getSession()

  // Protected routes
  if (!session && req.nextUrl.pathname.startsWith('/dashboard')) {
    return NextResponse.redirect(new URL('/login', req.url))
  }

  // Redirect logged-in users from auth pages
  if (session && (req.nextUrl.pathname === '/login' || req.nextUrl.pathname === '/register')) {
    return NextResponse.redirect(new URL('/dashboard', req.url))
  }

  return res

The description mentions real-time subscriptions and storage, but the SKILL.md does not provide any guidance or patterns for these features. This is a gap between the stated scope and the actual content.

Daftar alat adalah petunjuk metadata, bukan kompatibilitas teruji. Prompt adalah saran.

Mulai dengan tugas kecil

1Baca sumber dan pastikan masukan, keluaran, dependensi, serta izin.
2Minta rencana dari agent. Setujui pengaturan dan biaya sebelum uji terisolasi.
3Periksa hasil dan berkas yang berubah. Laporkan hanya yang dijalankan dan simpan revisi sumber.

Periksa dependensi, kunci API, dan biaya layanan pihak ketiga pada sumber. Repositori publik tidak berarti semua layanan gratis.
