// MULTI-STAGE BUILD para otimização

// 1. BASE STAGE
FROM oven/bun:1.2.9-slim AS base
// - Imagem oficial do Bun otimizada
// - Versão slim para menor tamanho
// - Label para Fly.io reconhecer

// 2. BUILD STAGE  
FROM base AS build
// - Instala dependências de build (gcc, python)
// - Copia package.json e bun.lock primeiro (cache layer)
// - Instala dependências
// - Copia código fonte
// - Executa build
// - Limpa node_modules e reinstala só produção

// 3. FINAL STAGE
FROM base
// - Copia apenas o resultado do build
// - Imagem final mínima
// - Expõe porta 3000
// - Comando padrão: bun run start

// VANTAGENS:
// ✅ Imagem final pequena (~50MB vs ~200MB)
// ✅ Cache eficiente das dependências  
// ✅ Sem ferramentas de build na produção
// ✅ Startup rápido do Bun
