# Schema 的设计能力
|
||
|
||
Schema 的设计能力主要体现在
|
||
|
||
- 邻近位置插入,可用于
|
||
- 插入新的 schema 节点
|
||
- 现有 schema 节点的拖拽移动
|
||
- schema 参数修改
|
||
|
||
设计器核心 API 和参数有:
|
||
|
||
- 设计器 API:`createDesignable()` & `useDesignable()`
|
||
- Schema 参数:`x-designer`,用于适配设计器组件
|
||
|
||
## 设计器 API
|
||
|
||
### createDesignable()
|
||
|
||
```ts
|
||
import { Schema } from '@nocobase/client';
|
||
|
||
const current = new Schema({
|
||
type: 'void',
|
||
'x-component': 'div',
|
||
});
|
||
|
||
const {
|
||
designable, // 是否可以配置
|
||
remove,
|
||
insertAdjacent, // 在某位置插入,四个位置:beforeBegin、afterBegin、beforeEnd、afterEnd
|
||
insertBeforeBegin, // 在当前节点的前面插入
|
||
insertAfterBegin, // 在当前节点的第一个子节点前面插入
|
||
insertBeforeEnd, // 在当前节点的最后一个子节点后面
|
||
insertAfterEnd, // 在当前节点的后面
|
||
} = createDesignable({
|
||
current,
|
||
});
|
||
|
||
const newSchema = {
|
||
type: 'void',
|
||
name: 'hello',
|
||
'x-component': 'Hello',
|
||
};
|
||
|
||
insertAfterBegin(newSchema);
|
||
|
||
console.log(current.toJSON());
|
||
{
|
||
type: 'void',
|
||
'x-component': 'div',
|
||
properties: {
|
||
hello: {
|
||
type: 'void',
|
||
'x-component': 'Hello',
|
||
},
|
||
},
|
||
}
|
||
```
|
||
|
||
### useDesignable()
|
||
|
||
React Hook 场景也可以用 `useDesignable()` 获取当前 schema 组件设计器的 API
|
||
|
||
```ts
|
||
const {
|
||
designable, // 是否可以配置
|
||
remove,
|
||
insertAdjacent, // 在某位置插入,四个位置:beforeBegin、afterBegin、beforeEnd、afterEnd
|
||
insertBeforeBegin, // 在当前节点的前面插入
|
||
insertAfterBegin, // 在当前节点的第一个子节点前面插入
|
||
insertBeforeEnd, // 在当前节点的最后一个子节点后面
|
||
insertAfterEnd, // 在当前节点的后面
|
||
} = useDesignable();
|
||
|
||
const schema = {
|
||
name: uid(),
|
||
'x-component': 'Hello',
|
||
};
|
||
|
||
// 在当前节点的前面插入
|
||
insertBeforeBegin(schema);
|
||
// 等同于
|
||
insertAdjacent('beforeBegin', schema);
|
||
|
||
// 在当前节点的第一个子节点前面插入
|
||
insertAfterBegin(schema);
|
||
// 等同于
|
||
insertAdjacent('afterBegin', schema);
|
||
|
||
// 在当前节点的最后一个子节点后面
|
||
insertBeforeEnd(schema);
|
||
// 等同于
|
||
insertAdjacent('beforeEnd', schema);
|
||
|
||
// 在当前节点的后面
|
||
insertAfterEnd(schema);
|
||
// 等同于
|
||
insertAdjacent('afterEnd', schema);
|
||
```
|
||
|
||
## 邻近位置插入
|
||
|
||
与 DOM 的 [insert adjacent](https://dom.spec.whatwg.org/#insert-adjacent) 概念相似,Schema 也提供了 `insertAdjacent()` 方法用于解决邻近位置的插入问题。
|
||
|
||
四个邻近位置
|
||
|
||
```ts
|
||
{
|
||
properties: {
|
||
// beforeBegin 在当前节点的前面插入
|
||
node1: {
|
||
properties: {
|
||
// afterBegin 在当前节点的第一个子节点前面插入
|
||
// ...
|
||
// beforeEnd 在当前节点的最后一个子节点后面
|
||
},
|
||
},
|
||
// afterEnd 在当前节点的后面
|
||
},
|
||
}
|
||
```
|
||
|
||
和 HTML 标签一样,Schema 组件库的组件也是可以相互组合,通过 insertAdjacent API 按实际需要插入在合理的邻近位置。
|
||
|
||
### 插入新的 schema 节点
|
||
|
||
在 Schema 组件里,可以直接通过 `useDesignable()` 在当前 Schema 的相邻位置插入新节点:
|
||
|
||
|
||
示例
|
||
|
||
```tsx
|
||
import React from 'react';
|
||
import { SchemaComponentProvider, SchemaComponent, useDesignable } from '@nocobase/client';
|
||
import { observer, Schema, useFieldSchema } from '@formily/react';
|
||
import { Button, Space } from 'antd';
|
||
import { uid } from '@formily/shared';
|
||
|
||
const Hello = observer((props) => {
|
||
const { insertAdjacent } = useDesignable();
|
||
const fieldSchema = useFieldSchema();
|
||
return (
|
||
<div>
|
||
<h1>{fieldSchema.name}</h1>
|
||
<Space>
|
||
<Button
|
||
onClick={() => {
|
||
insertAdjacent('beforeBegin', {
|
||
'x-component': 'Hello',
|
||
});
|
||
}}
|
||
>
|
||
before begin
|
||
</Button>
|
||
<Button
|
||
onClick={() => {
|
||
insertAdjacent('afterBegin', {
|
||
'x-component': 'Hello',
|
||
});
|
||
}}
|
||
>
|
||
after begin
|
||
</Button>
|
||
<Button
|
||
onClick={() => {
|
||
insertAdjacent('beforeEnd', {
|
||
'x-component': 'Hello',
|
||
});
|
||
}}
|
||
>
|
||
before end
|
||
</Button>
|
||
<Button
|
||
onClick={() => {
|
||
insertAdjacent('afterEnd', {
|
||
'x-component': 'Hello',
|
||
});
|
||
}}
|
||
>
|
||
after end
|
||
</Button>
|
||
</Space>
|
||
<div style={{ margin: 50 }}>{props.children}</div>
|
||
</div>
|
||
);
|
||
});
|
||
|
||
const Page = observer((props) => {
|
||
return <div>{props.children}</div>;
|
||
});
|
||
|
||
export default () => {
|
||
return (
|
||
<SchemaComponentProvider components={{ Page, Hello }}>
|
||
<SchemaComponent
|
||
schema={{
|
||
type: 'void',
|
||
name: 'page',
|
||
'x-component': 'Page',
|
||
properties: {
|
||
hello1: {
|
||
type: 'void',
|
||
'x-component': 'Hello',
|
||
},
|
||
},
|
||
}}
|
||
/>
|
||
</SchemaComponentProvider>
|
||
);
|
||
}
|
||
```
|
||
|
||
### 现有 schema 节点的拖拽移动
|
||
|
||
insertAdjacent 等方法也可用于节点的拖拽移动
|
||
|
||
```tsx
|
||
import React from 'react';
|
||
import { uid } from '@formily/shared';
|
||
import { observer, useField, useFieldSchema } from '@formily/react';
|
||
import { DndContext, DragEndEvent, useDraggable, useDroppable } from '@dnd-kit/core';
|
||
import { SchemaComponent, SchemaComponentProvider, createDesignable, useDesignable } from '@nocobase/client';
|
||
|
||
const useDragEnd = () => {
|
||
const { refresh } = useDesignable();
|
||
|
||
return ({ active, over }: DragEndEvent) => {
|
||
const activeSchema = active?.data?.current?.schema;
|
||
const overSchema = over?.data?.current?.schema;
|
||
|
||
if (!activeSchema || !overSchema) {
|
||
return;
|
||
}
|
||
|
||
const dn = createDesignable({
|
||
current: overSchema,
|
||
});
|
||
|
||
dn.on('insertAdjacent', refresh);
|
||
dn.insertBeforeBeginOrAfterEnd(activeSchema);
|
||
};
|
||
};
|
||
|
||
const Page = observer((props) => {
|
||
return <DndContext onDragEnd={useDragEnd()}>{props.children}</DndContext>;
|
||
});
|
||
|
||
function Draggable(props) {
|
||
const { attributes, listeners, setNodeRef, transform } = useDraggable({
|
||
id: props.id,
|
||
data: props.data,
|
||
});
|
||
const style = transform
|
||
? {
|
||
transform: `translate3d(${transform.x}px, ${transform.y}px, 0)`,
|
||
}
|
||
: undefined;
|
||
|
||
return (
|
||
<button ref={setNodeRef} style={style} {...listeners} {...attributes}>
|
||
{props.children}
|
||
</button>
|
||
);
|
||
}
|
||
|
||
function Droppable(props) {
|
||
const { isOver, setNodeRef } = useDroppable({
|
||
id: props.id,
|
||
data: props.data,
|
||
});
|
||
const style = {
|
||
color: isOver ? 'green' : undefined,
|
||
};
|
||
|
||
return (
|
||
<div ref={setNodeRef} style={style}>
|
||
{props.children}
|
||
</div>
|
||
);
|
||
}
|
||
|
||
const Block = observer((props) => {
|
||
const field = useField();
|
||
const fieldSchema = useFieldSchema();
|
||
return (
|
||
<Droppable id={field.address.toString()} data={{ schema: fieldSchema }}>
|
||
<div style={{ marginBottom: 20, padding: '20px', background: '#f1f1f1' }}>
|
||
Block {fieldSchema.name}{' '}
|
||
<Draggable id={field.address.toString()} data={{ schema: fieldSchema }}>
|
||
Drag
|
||
</Draggable>
|
||
</div>
|
||
</Droppable>
|
||
);
|
||
});
|
||
|
||
export default function App() {
|
||
return (
|
||
<SchemaComponentProvider components={{ Page, Block }}>
|
||
<SchemaComponent
|
||
schema={{
|
||
type: 'void',
|
||
name: 'page',
|
||
'x-component': 'Page',
|
||
properties: {
|
||
block1: {
|
||
'x-component': 'Block',
|
||
},
|
||
block2: {
|
||
'x-component': 'Block',
|
||
},
|
||
block3: {
|
||
'x-component': 'Block',
|
||
},
|
||
},
|
||
}}
|
||
/>
|
||
</SchemaComponentProvider>
|
||
);
|
||
}
|
||
```
|
||
|
||
## `x-designer` 的应用
|
||
|
||
`x-designer` 通常只在 BlockItem、CardItem、FormItem 等包装器组件中使用。
|
||
|
||
```ts
|
||
{
|
||
type: 'object',
|
||
properties: {
|
||
title: {
|
||
type: 'string',
|
||
title: '标题',
|
||
'x-decorator': 'FormItem',
|
||
'x-component': 'Input',
|
||
'x-designer': 'FormItem.Designer',
|
||
},
|
||
status: {
|
||
type: 'string',
|
||
title: '状态',
|
||
'x-decorator': 'FormItem',
|
||
'x-component': 'Select',
|
||
'x-designer': 'FormItem.Designer',
|
||
},
|
||
},
|
||
}
|
||
```
|
||
|
||
说明:NocoBase 提供的 Schema 设计器是以工具栏形式直接嵌入于界面,当激活界面配置时(`designable = true`),`x-designer` 组件(设计器工具栏)会显示出来,就可以通过工具栏更新当前 schema 组件了,工具栏提供的设计能力包括:
|
||
|
||
- 拖拽移动:DndContext + DragHandler
|
||
- 插入新节点:SchemaInitializer
|
||
- 参数配置:SchemaSettings
