Go Echo フレームワーク 本番運用ガイド（v5 新API・ルーティング・Context・ミドルウェア・バインディング/バリデーション・集中エラー処理・グレースフルシャットダウン）
Echo は『net/http の素朴さ』と『本番に必要な部品』のちょうど中間にいるからこそ、設計者の判断がそのまま品質に出るフレームワークです。本クラスタは Echo を採用した後の『どう本番で作るか』に集中します——まず v5 の破壊的変更（ハンドラ署名が func(c *echo.Context) error へ、ロガーが log/slog へ、middleware.Logger/Timeout の削除、e.Shutdown を廃した StartConfig{GracefulTimeout} への一本化）を押さえ、ルーティングの優先順位とグループによる権限境界、Context での読み書き、SIGTERM を取りこぼさないグレースフルシャットダウン、Recover を最外周に据えたミドルウェアの並び順と CORS/CSRF/Secure/JWT(echo-jwt)/RateLimiter の設定、DTO 分離と go-playground/validator による境界バリデーション、握りつぶさず return して集中 HTTPErrorHandler で整形するエラー設計に加え、pgx/sqlc/GORM のデータベース層とトランザクション境界、JWT 認証・RBAC・リフレッシュトークンの回転、クリーンアーキテクチャと google/wire の DI、httptest/echotest/testcontainers のテスト戦略、Docker/distroless/ECS/Cloud Run のデプロイ、Echo vs Gin の技術選定までを体系化します。実際に Go/Echo + google/wire でクリーンアーキテクチャのバックエンドを構築した知見を根拠に、ハンドラを薄く保ち DI でテスト可能にする、落ちない・追える・変更しやすい API の作り方を、Echo 公式ドキュメント（v5）に忠実な実コードで解説します。

Go Echo Framework Production-Operations Guide: Building APIs That Don't Fall Over with v5's New API, Routing, Context, and Graceful Shutdown
An implementation guide to operating Go's Echo framework at production quality. Faithful to the official documentation (v5), it explains the v4→v5 breaking changes (*echo.Context, slog, StartConfig), routing, Context, binding and validation, centralized error handling, graceful shutdown, testing, Docker deployment, and the Echo adoption decision—all in real code.
