## L7 地理空间数据可视分析引擎
|
|||
|
|
|||
|
L7 是由蚂蚁金服 AntV 数据可视化团队推出的基于 WebGL 的开源大规模地理空间数据可视分析开发框架。L7 中的 L 代表 Location,7 代表世界七大洲,寓意能为全球位置数据提供可视分析的能力。L7 以图形符号学为理论基础,将抽象复杂的空间数据转化成 2D、3D 符号,通过颜色、大小、体积、纹理等视觉变量实现丰富的可视化表达。

|
## Development
|
|||
|
|
|||
|
使用 Yarn Workspace 完成依赖安装以及各包之间的 link 工作:
|
|||
|
```bash
|
|||
|
yarn install
|
|||
|
```
|
|||
|
|
|||
|
开发模式:
|
|||
|
```bash
|
|||
|
yarn watch
|
|||
|
```
|
|||
|
|
|||
|
运行 Demo
|
|||
|
```bash
|
|||
|
yarn storybook
|
|||
|
```
|
|||
|
|
|||
|
代替 `git commit` 提交:
|
|||
|
```bash
|
|||
|
yarn commit
|
|||
|
```
|
|||
|
|
|||
|

|
|||
|
|
|||
|
```bash

|||
|
npm start
|
|||
|
```
|
|||
|
visit http://localhost:8000/
|
|||
|
|
|||
|
## Add Package
|
|||
|
|
|||
|
add new package:
|
|||
|
```bash
|
|||
|
lerna create my-pack -y
|
|||
|
```
|
|||
|
|
|||
|
将 ui-lib 作为 my-pack 的依赖:
|
|||
|
```bash
|
|||
|
yarn workspace my-pack add ui-lib/1.0.0
|
|||
|
```
|
|||
|
|
|||
|
将 lodash 添加为所有 package 的依赖(不包含root)
|
|||
|
```bash
|
|||
|
yarn workspaces run add lodash
|
|||
|
```
|
|||
|
|
|||
|
