示例:

/**
 * defaultShowCode: true
 */
import React from 'react';
import { Link, Outlet } from 'react-router-dom';
import { Application } from '@nocobase/client';

const Home = () => <h1>Home</h1>;
const About = () => <h1>About</h1>;

const Layout = () => {
  return <div>
    <div><Link to={'/'}>Home</Link>, <Link to={'/about'}>About</Link></div>
    <Outlet />
  </div>
}

const app = new Application({
  router: {
    type: 'memory',
    initialEntries: ['/']
  }
})

app.router.add('root', {
  element: <Layout />
})

app.router.add('root.home', {
  path: '/',
  element: <Home />
})

app.router.add('root.about', {
  path: '/about',
  element: <About />
})

export default app.getRootComponent();

SchemaComponent

路由可以通过 JSON 的方式配置,可以注册诸多可供路由使用的组件模板,以方便各种场景支持,但是这些组件还是需要开发编写和维护,所以进一步将组件抽象,转换成配置化的方式。如:

/**
 * defaultShowCode: true
 * title: Schema Component
 */
import React from 'react';
import { ISchema } from '@formily/react';
import { SchemaComponentProvider, SchemaComponent } from '@nocobase/client';

const schema: ISchema = {
  name: 'hello',
  'x-component': 'Hello',
  'x-component-props': {
    name: 'World',
  },
};

const Hello = ({ name }) => <h1>Hello {name}!</h1>;

export default function App() {
  return (
    <SchemaComponentProvider components={{ Hello }}>
      <SchemaComponent schema={schema} />
    </SchemaComponentProvider>
  )
};

可以通过 schema 方式配置的组件,称之为 schema 组件。在 SchemaComponentProvider 里注册各种 JSX 组件,编写相应的 schema再通过 SchemaComponent 渲染。SchemaComponent 的 schema 就是 Formily 的 Schema。实际上 SchemaComponent 就是 Formily 的 SchemaField,之所以叫 SchemaComponent是因为 SchemaComponent 可用于构建页面的各个部分,不局限于表单场景。

思维转换:

虽然 Formily 的核心是致力于解决表单的复杂问题但是随着不断的演变已经不局限在表单层面了。Formily 核心提供了 Form 和 Field 两个非常重要的模型Form 提供了路径系统和联动模型也同样适用于页面视图Field 实际上也可以理解为组件,分为有值组件和无值组件两类,有值组件例如 Input、Select 等,无值组件例如 Drawer、Button 等。有值组件的数值又可以分不同类型String、Number、Boolean、Object、Array 等等,无值组件没有数值,所以用 Void 表示,和 Formily 的 Field、ArrayField、ObjectField、VoidField 都对应上了。

为了适应动态的配置化表单解决方案Formily 又提炼了 Schema 协议DSL这个协议完全适用于描述组件模型用类 JSON Schema 的语法描述组件结构和对应的数值类型,这个 Schema 也是 SchemaComponent 的重要组成部分。

  • Schema 是一个树结构,多个节点以树形结构连接起来,其中的一个 property 表示的就是其中的一个 Schema 节点。
  • 单 Schema 节点(不包括 properties由核心 x-component、包装器 x-decorator、设计器 x-designable 三个组件构成。
    • x-component 核心组件
    • x-decorator 包装器,不同场景中,同一个核心组件,可能使用不同的包装器,如 FormItem、CardItem、BlockItem、Editable 等
    • x-designable 节点设计器NocoBase 的扩展参数),一般为当前 schema 节点的配置表单。与 Formily 提供的 Designable 解决方案不同,x-designable 直接作用于当前 schema 节点,使用和配置不分离。

理论上,很多现有组件都可以直接转为 schema 组件,但是并不一定好用。以 Drawer 为例,常规 JSX 的写法一般是这样的:

/**
 * defaultShowCode: true
 * title: JSX Drawer
 */
import React, { useState } from 'react';
import { Drawer, Button } from 'antd';

const App: React.FC = () => {
  const [visible, setVisible] = useState(false);
  const showDrawer = () => {
    setVisible(true);
  };
  const onClose = () => {
    setVisible(false);
  };
  return (
    <>
      <Button type="primary" onClick={showDrawer}>
        Open
      </Button>
      <Drawer
        title="Basic Drawer"
        placement="right"
        onClose={onClose}
        visible={visible}
        footer={
          <Button onClick={onClose}>关闭</Button>
        }
      >
        <p>Some contents...</p>
        <p>Some contents...</p>
        <p>Some contents...</p>
      </Drawer>
    </>
  );
};

export default App;

将组件转换成 schema如果 1:1 转换是这样的:

/**
 * defaultShowCode: true
 * title: Drawer Schema
 */
import React, { useMemo } from 'react';
import { SchemaComponentProvider, SchemaComponent } from '@nocobase/client';
import { Drawer as AntdDrawer, Button } from 'antd';
import { createForm } from '@formily/core';
import { RecursionField } from '@formily/react';

const Drawer = (props) => {
  const { footerSchema, ...others } = props;
  return (
    <AntdDrawer
      footer={
        footerSchema && <RecursionField schema={footerSchema} onlyRenderProperties />
      }
      {...others}
    />
  );
};

const schema = {
  type: 'object',
  properties: {
    b1: {
      type: 'void',
      'x-component': 'Button',
      'x-component-props': {
        children: 'Open',
        type: 'primary',
        onClick: '{{showDrawer}}',
      },
    },
    d1: {
      type: 'void',
      'x-component': 'Drawer',
      'x-component-props': {
        title: 'Basic Drawer',
        onClose: '{{onClose}}',
        footerSchema: {
          type: 'object',
          properties: {
            fb1: {
              type: 'void',
              'x-component': 'Button',
              'x-component-props': {
                children: 'Close',
                onClick: '{{onClose}}',
              },
            },
          },
        },
      },
    },
  },
};

export default function App() {
  const form = useMemo(() => createForm(), []);
  const showDrawer = () => {
    form.query('d1').take((field) => {
      field.componentProps.visible = true;
    });
  };
  const onClose = () => {
    form.query('d1').take((field) => {
      field.componentProps.visible = false;
    });
  };
  return (
    <SchemaComponentProvider
      form={form}
      components={{ Drawer, Button }}
    >
      <SchemaComponent schema={schema} scope={{ showDrawer, onClose }} />
    </SchemaComponentProvider>
  );
}

这个例子讲述了怎么将组件转换为可 Schema 配置,虽然达成了某种效果,但并不是一个很好的示例。

  • 一个 property 就是一个 Schema 节点Drawer 的 Schema 由平行的两个 schema 节点组成,不利于管理;
  • 需要额外的自定义 scope 支持 drawer 组件 visible 的状态管理,而且这里自定义的 scope 复用性差;
  • footer 需要特殊处理。在 x-component-props 里加了个 footerSchema 参数。但这个 footerSchema 并不是一个常规的 schema 节点,因为不是在 properties 里,不利于后端 schema 存储的统一规划;
  • 删除 drawer需要删除两个 schema 节点;
  • 后端如何输出 drawer 这部分的 schema 也非常不方便,因为 drawer 由平行的两个节点组成。

为了解决上述问题,从结构上做了一些改良:

{
  type: 'object',
  properties: {
    a1: {
      'x-component': 'Action',
      title: 'Open',
      properties: {
        d1: {
          'x-component': 'Action.Drawer',
          title: 'Drawer Title',
          properties: {
            c1: {
              'x-content': 'Hello',
            },
            f1: {
              'x-component': 'Action.Drawer.Footer',
              properties: {
                a1: {
                  'x-component': 'Action',
                  title: 'Close',
                  'x-component-props': {
                    useAction: '{{ useCloseAction }}',
                  },
                },
              },
            },
          },
        },
      },
    },
  },
}

以上示例,自定义了一个 Action 组件,用于配置按钮操作,又扩展了 Action.Drawer 和 Action.Drawer.Footer 两个特殊节点,分别用于配置抽屉弹框和抽屉的 footer。以上 schema 是个标准的组件树结构层次十分分明。组件树的各个节点层次分明schema 的增删改查就完全是标准流程了。

  • 查询 Drawer 的 schema只需要把 a1 节点的 json 全部输出就可以。
  • 修改各个节点和子节点都可以单节点独立处理,逻辑一致。
  • 删除时,直接删除不需要的节点就可以了。
  • 有利于扩展,比如继续增加 Action.Modal、Action.Modal.Footer 两个节点用于配置对话框。

Action.Drawer 完整的例子如下:

/**
 * title: Action.Drawer
 */
import React, { createContext, useContext, useMemo, useState } from 'react';
import { createPortal } from 'react-dom';
import { Button, Drawer } from 'antd';
import { SchemaComponentProvider, SchemaComponent } from '@nocobase/client';
import { observer, RecursionField, useField, useFieldSchema, ISchema } from '@formily/react';

const VisibleContext = createContext(null);

const useA = () => {
  return {
    async run() {},
  };
};

function useCloseAction() {
  const [, setVisible] = useContext(VisibleContext);
  return {
    async run() {
      setVisible(false);
    },
  };
}

const Action: any = observer((props: any) => {
  const { useAction = useA, onClick, ...others } = props;
  const [visible, setVisible] = useState(false);
  const schema = useFieldSchema();
  const field = useField();
  const { run } = useAction();
  return (
    <VisibleContext.Provider value={[visible, setVisible]}>
      <Button
        {...others}
        onClick={() => {
          onClick && onClick();
          setVisible(true);
          run();
        }}
      >
        {schema.title}
      </Button>
      <RecursionField basePath={field.address} schema={schema} onlyRenderProperties />
    </VisibleContext.Provider>
  );
}, { displayName: 'Action' });

Action.Drawer = observer((props: any) => {
  const [visible, setVisible] = useContext(VisibleContext);
  const schema = useFieldSchema();
  const field = useField();
  return (
    <>
      {createPortal(
        <Drawer
          title={schema.title}
          visible={visible}
          onClose={() => setVisible(false)}
          footer={

              schema={schema}
              onlyRenderProperties
              filterProperties={(s) => {
                return s['x-component'] === 'Action.Drawer.Footer';
              }}
            />
          }
        >
          <RecursionField
            basePath={field.address}
            schema={schema}
            onlyRenderProperties
            filterProperties={(s) => {
              return s['x-component'] !== 'Action.Drawer.Footer';
            }}
          />
        </Drawer>,
        document.body,
      )}
    </>
  );
}, { displayName: 'Action.Drawer' });

Action.Drawer.Footer = observer((props: any) => {
  const field = useField();
  const schema = useFieldSchema();
  return <RecursionField basePath={field.address} schema={schema} onlyRenderProperties />;
}, { displayName: 'Action.Drawer.Footer' });

const schema: ISchema = {

            },
            f1: {
              'x-component': 'Action.Drawer.Footer',

                },
              },
            },

export default function App() {
  return (
    <SchemaComponentProvider components={{ Action }} scope={{ useCloseAction }}>
      <SchemaComponent schema={schema} />
    </SchemaComponentProvider>
  );
}

Designable

SchemaComponent 基于 Formily 的 SchemaFieldFormily 提供了 Designable 来解决 Schema 的配置问题,但是这套方案:

  • 需要维护两套代码,以 antd 为例,需要同时维护 @formily/antd 和 @designable/formily-antd 两套代码
  • 使用和设计分离,在设计器界面表单无法正常工作

另辟蹊径NocoBase 构想了一种更为便捷的配置方案,使用和配置也可以兼顾,只需要维护一套代码。为此,提炼了一个简易的 useDesignable() Hook可用于任意 Schema 组件中,动态配置 Schema实时更新实时渲染。

Hook API

const {
  designable,         // 是否可以配置
  patch,              // 更新当前节点配置
  remove,             // 移除当前节点
  insertAdjacent,     // 在当前节点的相邻位置插入四个位置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 = {
  '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);

insertAdjacent 的几个插入的位置:

{
  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
  },
}

并不是所有场景都能使用 hook所以提供了 createDesignable() 方法(实际上 useDesignable() 也是基于它来实现):

const dn = createDesignable({
  current: schema,
});

dn.on('afterInsertAdjacent', (position, schema) => {

});

dn.insertAfterEnd(schema);

相关例子如下:

insertAdjacent 操作不仅可以用于新增节点,也可以用于现有节点的位置移动,如以下拖拽排序的例子:

/**
 * title: 拖拽排序
 */
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('afterInsertAdjacent', refresh);
    dn.insertBeforeBeginOrAfterEnd(activeSchema);
  };
};

const Page = observer((props) => {
  return <DndContext onDragEnd={useDragEnd()}>{props.children}</DndContext>;
}, { displayName: 'Page' });

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

  );
}, { displayName: 'Block' });

export default function App() {
  return (

            },
            block3: {
              'x-component': 'Block',
            },
          },
        }}
      />
    </SchemaComponentProvider>
  );
}

APIClient

在 WEB 应用里,客户端请求无处不在。为了便于客户端请求,提供的 API 有:

  • APIClient客户端 SDK
  • APIClientProvider提供 APIClient 实例的 Context全局共享
  • useRequest():需要结合 APIClientProvider 来使用
  • useApiClient():获取到当前配置的 apiClient 实例
const api = new APIClient({
  request, // 将 request 抛出去,方便各种自定义适配
});
api.request(options);
api.resource(name);

<APIClientProvider apiClient={api}>
  {/* children */}
</APIClientProvider>

useRequest() 需要结合 APIClientProvider 一起使用,是对 ahooks 的 useRequest 的封装,支持 resource 请求。

const { data, loading } = useRequest();

Providers

客户端的扩展以 Providers 的形式存在,提供各种可供组件使用的 Context可全局也可以局部使用。上文我们已经介绍了核心的三个 Providers

  • SchemaComponentProvider提供配置 Schema 所需的各种组件
  • ApiClientProvider提供客户端 SDK

除此之外,还有:

  • Router实际也是 Provider提供 History 的 Context对应的有 BrowserRouterHashRouter、MemoryRouter、NativeRouter、StaticRouter 几种可选方案
  • AntdConfigProvider为 antd 组件提供统一的全局化配置
  • I18nextProvider提供国际化解决方案
  • ACLProvider提供权限配置plugin-acl 的前端模块
  • CollectionManagerProvider提供全局的数据表配置plugin-collection-manager 的前端模块
  • SystemSettingsProvider提供系统设置plugin-system-settings 的前端模块
  • 其他扩展

多个 Providers 需要嵌套使用:

<ApiClientProvider>
  <SchemaComponentProvider>
      {...}
  </SchemaComponentProvider>
</ApiClientProvider>

但是这样的方式不利于 Providers 的管理和扩展,为此提炼了 compose() 函数用于配置多个 providers如下

Application

上文例子的 Providers 还是差点意思,再进一步封装改造:

const app = new Application({});

app.use(ApiClientProvider);
app.use([SchemaComponentProvider, { components: { Hello } }]);
app.use((props) => {
  return (
    <div>
      <Link to={'/'}>Home</Link>,<Link to={'/about'}>About</Link>
      <RouteSwitch routes={routes} />
    </div>
  );
});

app.mount('#root');
// 等于
ReactDOM.render(<App/>, document.getElementById('root'));

对比 NocoBase Server Application 中间件的核心实现:

app.use((ctx, next) => {});
const ctx = this.createContext(req, res)
await compose(app.middleware)(ctx);
await respond(ctx);

通过 app.use() 方法注册各种中间件插件,最后由 compose 来处理中间件,如果有需要也可以往 app.context 里添加各种东西待用。前端在处理 Provider 时也是类似的机制,这也是为什么客户端的扩展是以 Provider 的形式存在的原因。

从例子来看,以 Provider 的形式扩展是个不错的方案,但是还有两个问题没有解决:

  • Provider 的顺序怎么处理
  • 如何动态的加载前端模块
