### dooringx-lib 是什么？
|
||
|
||
dooringx-lib 是 dooringx 的基座，是移除了 dooringx 插件的可视化拖拽框架。
|
||
|
||
dooringx-lib 提供自己的一套数据流事件机制以及弹窗等解决方案，可以让你更快地自己定制开发可视化拖拽平台。
|
||
|
||
### dooringx-lib 如何工作？
|
||
|
||
|
||
dooringx-lib 在运行时维护一套数据流，主要分为json数据部分，左侧组件部分，右侧配置项部分，快捷键部分，弹窗部分，事件与函数部分，数据源部分。
|
||
|
||
其除了提供基础的拖拽、移动、缩放、全选、旋转等功能外，还可以使用暴露的组件。如果觉得组件不够定制化，可以调整样式或者自己重新写。
|
||
|
||
|
||
### 快速上手
|
||
|
||
|
||
#### 安装
|
||
|
||
使用 npm 或者 yarn 安装
|
||
|
||
```bash
|
||
npm i dooringx-lib
|
||
```

||
参考demo:

useStoreState,
|
||
innerContainerDragUp,
|
||
LeftConfig,
|
||
ContainerWrapper,
|
||
Control,
|
||
} from 'dooringx-lib';
|
||
import { useContext } from 'react';
|
||
import { configContext } from '@/layouts';
|
||
import { useCallback } from 'react';
|
||
import { PREVIEWSTATE } from '@/constant';
|
||
|
||
export const HeaderHeight = '40px';
|
||
|
||
export default function IndexPage() {
|
||
const config = useContext(configContext);
|
||
|
||
const everyFn = () => {};
|
||
|
||
const subscribeFn = useCallback(() => {
|
||
localStorage.setItem(PREVIEWSTATE, JSON.stringify(config.getStore().getData()));
|
||
}, [config]);
|
||
|
||
const [state] = useStoreState(config, subscribeFn, everyFn);
|
||
|
||
return (
|
||
<div {...innerContainerDragUp(config)}>
|
