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
