MyApp Sample (Next.js + Go + Postgres)

構成

• frontend: Next.js (simple) - ports: 3000
• backend: Go (Echo + GORM) - ports: 8080
• db: Postgres - ports: 5432

ローカル起動（Dockerがある場合）

1. docker-compose build
2. docker-compose up

Notes

• Backend depends on golang modules: echo, gorm, postgres driver. Add these to backend/go.mod or run go get locally if building outside Docker.
• Frontend uses Next.js; npm install will install dependencies in container.
