## 编译当前平台二进制（纯 Go SQLite，无需 CGO）
build: frontend-build

	@echo "✓ 编译完成: $(BUILD_DIR)/$(APP_NAME)"

## Windows amd64（先打包前端再 embed）
build-windows: frontend-build

## 整理依赖
tidy:
	$(GO) mod tidy

## 本地运行（仅后端，使用已 embed 的前端；数据目录与 dist 二进制一致）
run:
	@mkdir -p $(DEV_DATA_DIR)
	$(GO) run $(MAIN_PKG) --data $(DEV_DATA_DIR)

## 前端热更新开发（后端 :3000 + Vite :5173，Ctrl+C 同时退出；数据目录与 dist 二进制一致）
dev:
	@echo "前端热更新: http://localhost:5173"
	@echo "后端 API  : http://localhost:3000"
	@echo "数据目录  : $(DEV_DATA_DIR) (与 dist 二进制一致)"
	@mkdir -p $(DEV_DATA_DIR)
	@trap 'kill 0' INT; \
	$(GO) run $(MAIN_PKG) --dev --data $(DEV_DATA_DIR) & \
	cd frontend && (test -d node_modules || npm install) && npm run dev

## 清理编译产物
clean:
	rm -rf $(BUILD_DIR)

## 构建 Docker 镜像
docker:
	docker build --build-arg VERSION=$(VERSION) -t $(REGISTRY_IMAGE):$(VERSION) -t $(REGISTRY_IMAGE):latest .

## Docker Compose 启动
compose-up:
	docker compose up -d --build

## Docker Compose 停止
compose-down:
	docker compose down
