概述
日志级别配置工作流是一个初级难度的工作流。为不同环境配置应用日志级别，平衡可观测性和性能。该工作流的目标是：Set appropriate log levels for development, staging, and production environments.
环境准备
执行本工作流需要以下环境：An application with a logging framework configured；Environment variable support for log level；A configuration file or startup script。请确保在开始前准备好所有必需的工具和资源，以避免中途因环境问题中断。
执行步骤
本工作流包含4个步骤。步骤1：Set development level——Configure DEBUG level for local development to see all log messages. 步骤2：Set staging level——Configure INFO level for staging to monitor without excessive output. 步骤3：Set production level——Configure WARN level for production to reduce volume and cost. 步骤4：Verify each environment——Start the application in each environment and confirm the log output level.
验证与清理
预期结果：Each environment has an appropriate log level configured and verified.。验证方法：Start the application in each environment and confirm the log output matches the configured level.。清理操作：No cleanup needed; log configuration should be committed.。estimatedMinutes 为 15 分钟。
代码示例
LOG_LEVEL=debug npm start # development
LOG_LEVEL=warn npm start # production
