Enable RLS di SEMUA tables ALTER TABLE users ENABLE ROW LEVEL SECURITY; ALTER TABLE posts ENABLE ROW LEVEL SECURITY; ALTER TABLE comments ENABLE ROW LEVEL SECURITY; -- 2. Bikin policies yang strict CREATE POLICY "Users can only view own data" ON users FOR SELECT USING (auth.uid() = id); -- 3. Jangan allow public access kecuali emang harus -- ❌ Bad CREATE POLICY "Anyone can do anything" ON sensitive_data FOR ALL USING (true); -- ✅ Good CREATE POLICY "Only authenticated users can read public posts" ON posts FOR SELECT USING (auth.role() = 'authenticated' AND status = 'published'); ``` ### Database Optimization ✅ ```sql -- 1. Tambahin indexes buat kolom yang sering di-query CREATE INDEX idx_posts_user_id ON posts(user_id); CREATE INDEX idx_posts_created_at ON posts(created_at DESC); CREATE INDEX idx_posts_status ON posts(status) WHERE status = 'published'; -- 2. Tambahin composite indexes buat kombinasi filter yang umum CREATE INDEX idx_posts_user_status ON posts(user_id, status); -- 3. Full-text search index CREATE INDEX idx_posts_search ON posts USING GIN(to_tsvector('english', title || ' ' || content)); -- 4. Foreign key constraints ALTER TABLE posts ADD CONSTRAINT fk_posts_user FOREIGN KEY (user_id) REFERENCES auth.users(id) ON DELETE CASCADE; ``` ### Environment Variables ✅ ```bash # .env.production NEXT_PUBLIC_SUPABASE_URL=https://xxxxx.supabase.co NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJhbGc... # Safe for client SUPABASE_SERVICE_ROLE_KEY=eyJhbGc... # SERVER-ONLY! Never expose! SUPABASE_JWT_SECRET=super-secret-jwt # For validating tokens # Database connection (for server-side direct connection) DATABASE_URL=postgresql://postgres:[password]@db.xxxxx.supabase.co:5432/postgres ``` ### Monitoring & Alerts ✅ Di Supabase Dashboard, setup: - [ ] Database usage alerts (80% threshold) - [ ] API request rate monitoring - [ ] Error rate tracking - [ ] Auth failure notifications - [ ] Storage quota warnings --- ## Praktik Terbaik Security ### 1. Row Level Security (RLS) Patterns #### Multi-tenancy Pattern ```sql -- Setiap table punya organization_id CREATE TABLE posts ( id UUID DEFAULT gen_random_uuid() PRIMARY KEY, organization_id UUID NOT NULL REFERENCES organizations(id), title TEXT NOT NULL, user_id UUID REFERENCES auth.users(id) ); -- Users cuma bisa liat data dari organisasi mereka CREATE POLICY "Org members can view org posts" ON posts FOR SELECT USING ( organization_id IN ( SELECT organization_id FROM memberships WHERE user_id = auth.uid() ) ); ``` #### Role-based Access Control (RBAC) ```sql -- User roles disimpan di custom claims atau metadata CREATE POLICY "Admins can do everything" ON posts FOR ALL USING ( auth.jwt() ->> 'role' = 'admin' ); CREATE POLICY "Editors can update but not delete" ON posts FOR UPDATE USING ( auth.jwt() ->> 'role' IN ('admin', 'editor') ); CREATE POLICY "Viewers can only read" ON posts FOR SELECT USING ( auth.jwt() ->> 'role' IN ('admin', 'editor', 'viewer') ); ``` #### Time-based Access ```sql -- Content cuma visible setelah tanggal publish CREATE POLICY "Published posts are viewable" ON posts FOR SELECT USING ( published_at IS NOT NULL AND published_at <= NOW() ); ``` ### 2. API Security ```typescript // Rate limiting pake Supabase Edge Functions import { serve } from 'https://deno.land/std@0.168.0/http/server.ts' const rateLimits = new Map() serve(async (req) => { const ip = req.headers.get('x-forwarded-for') || 'unknown' const now = Date.now() // Ambil request timestamps buat IP ini const requests = rateLimits.get(ip) || [] // Hapus requests yang lebih lama dari 1 menit const recentRequests = requests.filter(time => now - time < 60000) // Cek apakah melebihi rate limit (60 requests per menit) if (recentRequests.length >= 60) { return new Response('Rate limit exceeded', { status: 429 }) } // Tambahin current request recentRequests.push(now) rateLimits.set(ip, recentRequests) // Process request... return new Response('OK') }) ``` ### 3. Input Validation ```typescript // Jangan pernah percaya input dari client async function createPost(title: string, content: string) { // ❌ Bad - Rentan terhadap injection const { data } = await supabase .from('posts') .insert({ title, content }) // ✅ Good - Validasi dulu if (!title || title.length < 3 || title.length > 200) { throw new Error('Invalid title length') } if (!content || content.length < 10 || content.length > 50000) { throw new Error('Invalid content length') } // Sanitize HTML kalo perlu const sanitizedContent = DOMPurify.sanitize(content) const { data, error } = await supabase .from('posts') .insert({ title: title.trim(), content: sanitizedContent }) if (error) throw error return data } ``` --- ## Optimasi Performance ### 1. Optimasi Database Query ```typescript // ❌ Bad - Multiple queries (masalah N+1) const { data: posts } = await supabase.from('posts').select('*') for (const post of posts) { const { data: author } = await supabase .from('users') .select('*') .eq('id', post.user_id) .single() post.author = author } // ✅ Good - Single query pake join const { data: posts } = await supabase .from('posts') .select(` *, author:users(id, name, avatar_url) `) ``` ### 2. Strategi Pagination ```typescript // ❌ Bad - Offset pagination (lambat buat dataset besar) const { data } = await supabase .from('posts') .select('*') .range(10000, 10020) // Lambat kalo offset-nya besar // ✅ Good - Cursor-based pagination const { data } = await supabase .from('posts') .select('*') .lt('created_at', lastPostTimestamp) // Cursor .order('created_at', { ascending: false }) .limit(20) ``` ### 3. Strategi Caching ```typescript // Server-side caching pake Next.js import { unstable_cache } from 'next/cache' export const getPublicPosts = unstable_cache( async () => { const { data } = await supabase .from('posts') .select('*') .eq('status', 'published') .order('created_at', { ascending: false }) .limit(20) return data }, ['public-posts'], { revalidate: 60, // Cache selama 60 detik tags: ['posts'] } ) // Invalidate cache kalo data berubah import { revalidateTag } from 'next/cache' async function createPost(post: Post) { await supabase.from('posts').insert(post) revalidateTag('posts') // Clear cache } ``` ### 4. Connection Pooling ```typescript // Server-side direct database connection import { createClient } from '@supabase/supabase-js' // Pake connection pooler buat serverless environments const supabase = createClient( process.env.NEXT_PUBLIC_SUPABASE_URL!, process.env.SUPABASE_SERVICE_ROLE_KEY!, { db: { schema: 'public', }, auth: { persistSession: false, autoRefreshToken: false, }, } ) ``` --- ## Praktik Terbaik Real-time ### 1. Subscriptions yang Efisien ```typescript // ❌ Bad - Subscribe ke seluruh table const subscription = supabase .channel('all-posts') .on('postgres_changes', { event: '*', schema: 'public', table: 'posts' }, (payload) => { // Ini trigger buat SEMUA posts, bahkan yang ga bisa dilihat user console.log(payload) } ) .subscribe() // ✅ Good - Filter subscriptions const userId = 'user-id' const subscription = supabase .channel('my-posts') .on( 'postgres_changes', { event: '*', schema: 'public', table: 'posts', filter: `user_id=eq.${userId}` // Cuma posts user ini }, (payload) => { console.log('My post changed:', payload) } ) .subscribe() ``` ### 2. Cleanup & Memory Leaks ```typescript // React component dengan cleanup yang bener import { useEffect } from 'react' function PostList() { useEffect(() => { const channel = supabase .channel('posts') .on('postgres_changes', { event: '*', table: 'posts' }, handleChange) .subscribe() // ✅ PENTING: Cleanup pas unmount return () => { channel.unsubscribe() } }, []) return

...

} ``` ### 3. Reconnection Logic ```typescript function setupRealtime() { const channel = supabase.channel('posts') channel .on('postgres_changes', { event: '*', table: 'posts' }, handleChange) .subscribe((status) => { if (status === 'SUBSCRIBED') { console.log('Connected to real-time') } if (status === 'CHANNEL_ERROR') { console.log('Error connecting, retrying...') // Implement exponential backoff setTimeout(() => setupRealtime(), 5000) } if (status === 'TIMED_OUT') { console.log('Connection timed out') } }) return channel } ``` --- ## Manajemen Biaya ### 1. Memahami Pricing (2025) **Free Tier (Murah meriah!):** - 500MB database storage - 1GB file storage - 50,000 monthly active users - 2GB bandwidth - Di-pause setelah 1 minggu ga aktif **Pro Plan ($25/bulan):** - 8GB database storage - 100GB file storage - 100,000 MAU - 250GB bandwidth - Ga pernah di-pause - Daily backups - Email support **Compute Credits:** Burst melebihi limits tanpa upgrade - bayar cuma buat pemakaian extra aja. ### 2. Tips Optimasi Biaya ```typescript // 1. Select kolom yang dibutuhin aja // ❌ Bad - Fetches semua const { data } = await supabase.from('posts').select('*') // ✅ Good - Cuma field yang perlu const { data } = await supabase.from('posts').select('id, title, created_at') // 2. Pake .single() pas fetch satu row const { data } = await supabase .from('posts') .select('*') .eq('id', postId) .single() // Lebih efisien daripada return array // 3. Implement pagination const { data } = await supabase .from('posts') .select('*') .range(0, 19) .limit(20) // 4. Pake RLS buat cegah over-fetching // Database otomatis filter hasil - lebih murah daripada filter di client ``` ### 3. Manajemen Biaya Storage ```typescript // Compress images sebelum upload async function uploadAvatar(file: File) { // Compress image const compressed = await compressImage(file, { maxWidth: 800, maxHeight: 800, quality: 0.8 }) const { data, error } = await supabase.storage .from('avatars') .upload(`${userId}.jpg`, compressed, { cacheControl: '3600', upsert: true, contentType: 'image/jpeg' }) return data } // Clean up file lama secara rutin async function cleanupOldFiles() { const thirtyDaysAgo = new Date() thirtyDaysAgo.setDate(thirtyDaysAgo.getDate() - 30) const { data: oldFiles } = await supabase.storage .from('temp') .list('uploads', { sortBy: { column: 'created_at', order: 'asc' } }) const filesToDelete = oldFiles ?.filter(file => new Date(file.created_at) < thirtyDaysAgo) .map(file => file.name) if (filesToDelete && filesToDelete.length > 0) { await supabase.storage .from('temp') .remove(filesToDelete) } } ``` --- ## Monitoring & Debugging ### 1. Error Tracking ```typescript // Centralized error handler async function queryWithErrorTracking( queryFn: () => Promise<{ data: T | null; error: any }> ) { const { data, error } = await queryFn() if (error) { // Log ke error tracking service (Sentry, dll.) console.error('Supabase error:', { message: error.message, details: error.details, hint: error.hint, code: error.code }) // Kirim ke monitoring if (typeof window !== 'undefined' && window.Sentry) { window.Sentry.captureException(error) } throw error } return data } // Usage const posts = await queryWithErrorTracking(() => supabase.from('posts').select('*') ) ``` ### 2. Performance Monitoring ```typescript // Track performa query async function timedQuery( name: string, queryFn: () => Promise ): Promise { const start = performance.now() try { const result = await queryFn() const duration = performance.now() - start // Log slow queries (> 1 detik) if (duration > 1000) { console.warn(`Slow query: ${name} took ${duration}ms`) } // Kirim ke analytics analytics.track('query_performance', { name, duration, timestamp: new Date().toISOString() }) return result } catch (error) { const duration = performance.now() - start console.error(`Query failed: ${name} after ${duration}ms`, error) throw error } } // Usage const posts = await timedQuery('fetch_posts', async () => { const { data } = await supabase.from('posts').select('*') return data }) ``` ### 3. Database Observability ```sql -- Enable query statistics CREATE EXTENSION IF NOT EXISTS pg_stat_statements; -- Cari slow queries SELECT query, calls, total_exec_time / 1000 as total_time_seconds, mean_exec_time / 1000 as mean_time_seconds FROM pg_stat_statements ORDER BY mean_exec_time DESC LIMIT 10; -- Cari indexes yang hilang SELECT schemaname, tablename, attname, n_distinct, correlation FROM pg_stats WHERE schemaname NOT IN ('pg_catalog', 'information_schema') AND n_distinct > 100 AND correlation < 0.1; ``` --- ## Backup & Disaster Recovery ### 1. Database Backups **Automatic Backups (Pro+):** - Daily automated backups - Point-in-time recovery (PITR) - Retensi 7 hari di Pro - Retensi 30 hari di Team+ ### 2. Script Backup Manual ```bash #!/bin/bash # backup-database.sh PROJECT_ID="your-project-id" DB_PASSWORD="your-db-password" TIMESTAMP=$(date +%Y%m%d_%H%M%S) BACKUP_FILE="backup_${TIMESTAMP}.sql" # Dump database pg_dump "postgresql://postgres:${DB_PASSWORD}@db.${PROJECT_ID}.supabase.co:5432/postgres" > $BACKUP_FILE # Compress gzip $BACKUP_FILE # Upload ke S3 atau storage lain aws s3 cp ${BACKUP_FILE}.gz s3://my-backups/supabase/ echo "Backup completed: ${BACKUP_FILE}.gz" ``` ### 3. Testing Backups ```typescript // Test backup restoration secara rutin async function testBackupRestoration() { // 1. Bikin test project // 2. Restore backup // 3. Jalanin smoke tests // 4. Verify integritas data const { data } = await supabase.from('users').select('count') console.log('Backup restoration test passed:', data) } ``` --- ## Strategi Migration ### 1. Schema Migrations ```sql -- migrations/001_create_posts.sql CREATE TABLE IF NOT EXISTS posts ( id UUID DEFAULT gen_random_uuid() PRIMARY KEY, user_id UUID REFERENCES auth.users(id) ON DELETE CASCADE, title TEXT NOT NULL, content TEXT, status TEXT DEFAULT 'draft' CHECK (status IN ('draft', 'published', 'archived')), created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(), updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW() ); CREATE INDEX idx_posts_user_id ON posts(user_id); CREATE INDEX idx_posts_status ON posts(status); ALTER TABLE posts ENABLE ROW LEVEL SECURITY; CREATE POLICY "Users can view own posts" ON posts FOR SELECT USING (auth.uid() = user_id); ``` ### 2. Data Migration ```typescript // Migrate data dari struktur lama ke baru async function migrateUserProfiles() { // Ambil semua users const { data: users } = await supabase .from('old_users') .select('*') // Transform dan insert ke table baru const newUsers = users?.map(user => ({ id: user.id, email: user.email_address, // Field diganti nama full_name: `${user.first_name} ${user.last_name}`, // Fields digabung created_at: user.registered_at // Field diganti nama })) if (newUsers) { const { error } = await supabase .from('users') .insert(newUsers) if (error) { console.error('Migration failed:', error) // Rollback kalo perlu } else { console.log(`Migrated ${newUsers.length} users`) } } } ``` --- ## Testing di Production ### 1. Feature Flags ```typescript // Pake database buat feature flags const { data: flags } = await supabase .from('feature_flags') .select('*') .eq('enabled', true) .single() function isFeatureEnabled(feature: string): boolean { return flags?.features?.includes(feature) ?? false } // Usage if (isFeatureEnabled('new_editor')) { return } else { return } ``` ### 2. A/B Testing ```typescript // Simpan user variant async function assignVariant(userId: string, experiment: string) { const variant = Math.random() < 0.5 ? 'A' : 'B' await supabase.from('user_experiments').insert({ user_id: userId, experiment, variant, assigned_at: new Date().toISOString() }) return variant } // Track conversion async function trackConversion(userId: string, experiment: string) { await supabase.from('conversions').insert({ user_id: userId, experiment, converted_at: new Date().toISOString() }) } ``` --- ## Kesimpulan Deploy Supabase ke production bukan cuma "push to production" aja - ada banyak hal yang perlu dipertimbangkan: ### Yang Harus Ada Sebelum Launch: 1. ✅ **Security**: RLS enabled di semua tables, policies udah di-test 2. ✅ **Performance**: Indexes udah dibuat, queries udah dioptimasi 3. ✅ **Monitoring**: Error tracking dan performance monitoring udah setup 4. ✅ **Backups**: Automated backups udah dikonfigurasi dan di-test 5. ✅ **Environment**: Env variables udah bener, secrets udah aman 6. ✅ **Cost Management**: Spend cap udah di-set, optimasi udah dilakuin ### Monitoring Setelah Launch: - [ ] Database usage trends - [ ] API error rates - [ ] Query performance - [ ] Authentication failures - [ ] Storage usage - [ ] Real-time connection counts ### Checklist Scaling: - [ ] Database indexes udah dioptimasi - [ ] Connection pooling udah dikonfigurasi - [ ] Caching strategy udah diimplementasi - [ ] CDN buat static assets - [ ] Edge Functions buat compute-heavy tasks - [ ] Pertimbangkan read replicas buat read-heavy apps ### Kesalahan Umum yang Harus Dihindari: - ❌ Lupa enable RLS (celah security besar!) - ❌ Ga ada indexes di kolom yang sering di-query - ❌ Expose service role key ke client - ❌ Ga ada monitoring/alerting setup - ❌ Ga pernah test backup - ❌ Ignore performa query sampe terlambat - ❌ Over-fetching data (select *) **Supabase Production = Secure + Fast + Monitored + Scalable** Dengan setup yang bener, Supabase bisa handle jutaan users tanpa drama. Mulai dari kecil, monitor semuanya, optimasi secara bertahap. Production-ready bukan berarti sempurna - tapi berarti aman, cukup cepat, dan observable!
