本项目包含了作者为B站课堂视频[《工作流设计器开发最佳实践》](https://www.bilibili.com/cheese/play/ss24484)的过程源码。教程中开发的组件也可用于实际生产环境中。以下是和使用文档和课程章节说明。 ## 演示地址 本工程提供两个演示站，分别覆盖库本身和真实业务集成两种形态：

  });
};

};

  if (isNumber(value) || isStringNumber(value)) return `${value}${defaultUnit}`;
  else if (isString(value)) return value;
  debugWarn(SCOPE, "binding value must be a string or number");
}
