预览组件
cd 您的组件名datav runhttp://localhost:1111/
预览页主要分为中心画布区,底部工具栏和右侧工具栏三部分,详细介绍如下:
- 中心画布区
- 中心画布区是用来展现组件,实时观测组件变化的区域。
- 所有右侧工具栏的配置、数据修改都会实时展示在中心画布的组件上。
- 组件的白框代表了组件的容器范围大小,每个方向上的白框都可以缩放来测试组件在任意方向缩放的表现。
- 底部工具栏可以切换组件的语言环境。
- 右侧工具栏右侧工具栏分为配置、数据、交互和发布4个面板。

发布组件
您可通过以下三种方式发布组件:
- 方式一(推荐)进入组件的目录地址下,执行datav publish命令,组件将自动打包压缩发布至账号所在域的服务器。
- 方式二进入组件的目录地址下,执行datav package命令,在组件目录外会有一个以
组件-版本号命名的tar.gz压缩包,将此压缩包上传到datav.aliyun.com的组件页,即可发布。- 创建组件包

- 方法三进入预览组件页面下的发布页面,单击发布,即可发布组件。
踩坑
问题:datav init 一直报错,
网上搜,说是gulp和node版本不一致
问题:组件上传不上去

字面意思是上传超限,实际是命名空间不对应导致;
组件包英文名:iwhalecloud-poc

package.json里也要对应上
so datav publish 
问题:使用datav login命令,让输入UID和token


问题:哪里设置视频自动播放呢?
文档中关于设置视频自动播放的方法不再有用了
