<Callout type="warning" title="先决条件"> 开始前,请确保已安装并配置 [shadcn/ui](https://ui.shadcn.com/docs/installation)(适配您的框架,如 Vite)和 [Plate UI](/docs/installation/plate-ui)。 </Callout>

本指南将逐步引导您在项目中构建 Plate 编辑器。

<Steps>

创建第一个编辑器

首先在项目中添加核心 Editor 组件:

bash
npx shadcn@latest add @plate/editor

接下来,在主应用文件(如 src/App.tsx)中创建基础编辑器。此示例在 EditorContainer 内设置了一个简单编辑器。

tsx
import { Plate, usePlateEditor } from 'platejs/react';

import { Editor, EditorContainer } from '@/components/ui/editor';

export default function App() {
  const editor = usePlateEditor(); // 初始化编辑器实例

  return (
    <Plate editor={editor}>
      <EditorContainer>
        <Editor placeholder="输入您精彩的内容..." />
      </EditorContainer>
    </Plate>
  );
}
<Callout type="info"> `usePlateEditor` 创建了一个记忆化的编辑器实例,确保在重新渲染时保持稳定。如需非记忆化版本,请使用 `createPlateEditor`。 </Callout> <ComponentPreview name="installation-next-01-editor-demo" height="200px" />

添加基础标记

通过文本格式化功能增强编辑器。添加 Basic Nodes KitFixedToolbarMarkToolbarButton 组件:

bash
npx shadcn@latest add @plate/basic-nodes-kit @plate/fixed-toolbar @plate/mark-toolbar-button
<Callout type="info"> `basic-nodes-kit` 包含所有基础插件(粗体、斜体、下划线、标题、引用块等)及后续步骤中将用到的组件。 </Callout>

更新 src/App.tsx 以包含这些组件和基础标记插件。 此示例添加了粗体、斜体和下划线功能。

tsx
import * as React from 'react';
import type { Value } from 'platejs';

import {
  BoldPlugin,
  ItalicPlugin,
  UnderlinePlugin,
} from '@platejs/basic-nodes/react';
import {
  Plate,
  usePlateEditor,
} from 'platejs/react';

import { Editor, EditorContainer } from '@/components/ui/editor';
import { FixedToolbar } from '@/components/ui/fixed-toolbar';
import { MarkToolbarButton } from '@/components/ui/mark-toolbar-button';

const initialValue: Value = [
  {
    type: 'p',
    children: [
      { text: 'Hello! Try out the ' },
      { text: 'bold', bold: true },
      { text: ', ' },
      { text: 'italic', italic: true },
      { text: ', and ' },
      { text: 'underline', underline: true },
      { text: ' formatting.' },
    ],
  },
];

export default function App() {
  const editor = usePlateEditor({
    plugins: [BoldPlugin, ItalicPlugin, UnderlinePlugin], // 添加标记插件
    value: initialValue,         // 设置初始内容
  });

  return (
    <Plate editor={editor}>
      <FixedToolbar className="justify-start rounded-t-lg">
        <MarkToolbarButton nodeType="bold" tooltip="Bold (⌘+B)">B</MarkToolbarButton>
        <MarkToolbarButton nodeType="italic" tooltip="Italic (⌘+I)">I</MarkToolbarButton>
        <MarkToolbarButton nodeType="underline" tooltip="Underline (⌘+U)">U</MarkToolbarButton>
      </FixedToolbar>
      <EditorContainer>
        <Editor placeholder="输入您精彩的内容..." />
      </EditorContainer>
    </Plate>
  );
}
<ComponentPreview name="installation-next-02-marks-demo" height="200px" />

添加基础元素

通过自定义组件引入标题和引用块等块级元素。

tsx
import * as React from 'react';
import type { Value } from 'platejs';

import {
  BlockquotePlugin,
  BoldPlugin,
  H1Plugin,
  H2Plugin,
  H3Plugin,
  ItalicPlugin,
  UnderlinePlugin,
} from '@platejs/basic-nodes/react';
import {
  Plate,
  usePlateEditor,
} from 'platejs/react';

import { BlockquoteElement } from '@/components/ui/blockquote-node';
import { Editor, EditorContainer } from '@/components/ui/editor';
import { FixedToolbar } from '@/components/ui/fixed-toolbar';
import { H1Element, H2Element, H3Element } from '@/components/ui/heading-node';
import { MarkToolbarButton } from '@/components/ui/mark-toolbar-button';
import { ToolbarButton } from '@/components/ui/toolbar'; // 通用工具栏按钮

const initialValue: Value = [
  {
    children: [{ text: 'Title' }],
    type: 'h3',
  },
  {
    children: [{ text: 'This is a quote.' }],
    type: 'blockquote',
  },
  {
    children: [
      { text: 'With some ' },
      { bold: true, text: 'bold' },
      { text: ' text for emphasis!' },
    ],
    type: 'p',
  },
];

export default function App() {
  const editor = usePlateEditor({
    plugins: [
      BoldPlugin,
      ItalicPlugin,
      UnderlinePlugin,
      H1Plugin.withComponent(H1Element),
      H2Plugin.withComponent(H2Element),
      H3Plugin.withComponent(H3Element),
      BlockquotePlugin.withComponent(BlockquoteElement),
    ],
    value: initialValue,
  });

  return (
    <Plate editor={editor}>
      <FixedToolbar className="flex justify-start gap-1 rounded-t-lg">
        <ToolbarButton onClick={() => editor.tf.h1.toggle()}>H1</ToolbarButton>
        <ToolbarButton onClick={() => editor.tf.h2.toggle()}>H2</ToolbarButton>
        <ToolbarButton onClick={() => editor.tf.h3.toggle()}>H3</ToolbarButton>
        <ToolbarButton onClick={() => editor.tf.blockquote.toggle()}>Quote</ToolbarButton>
        <MarkToolbarButton nodeType="bold" tooltip="Bold (⌘+B)">B</MarkToolbarButton>
        <MarkToolbarButton nodeType="italic" tooltip="Italic (⌘+I)">I</MarkToolbarButton>
        <MarkToolbarButton nodeType="underline" tooltip="Underline (⌘+U)">U</MarkToolbarButton>
      </FixedToolbar>
      <EditorContainer>
        <Editor placeholder="输入您精彩的内容..." />
      </EditorContainer>
    </Plate>
  );
}
<ComponentPreview name="installation-next-03-elements-demo" height="200px" /> <Callout type="info" title="组件注册"> 注意我们如何使用 `Plugin.withComponent(Component)` 将组件与其对应的插件注册。这是将 React 组件与 Plate 插件关联的推荐方式。

如需快速开始使用预配置的常见插件和组件,可使用 editor-basic 区块:

bash
npx shadcn@latest add @plate/editor-basic

这将为您处理大部分样板代码。 </Callout>

处理编辑器值

为了使编辑器内容持久化,我们集成 localStorage 来保存和加载编辑器的值。

tsx
import * as React from 'react';
import type { Value } from 'platejs';

import {
  BlockquotePlugin,
  BoldPlugin,
  H1Plugin,
  H2Plugin,
  H3Plugin,
  ItalicPlugin,
  UnderlinePlugin,
} from '@platejs/basic-nodes/react';
import {
  Plate,
  usePlateEditor,
} from 'platejs/react';

import { BlockquoteElement } from '@/components/ui/blockquote-node';
import { Editor, EditorContainer } from '@/components/ui/editor';
import { FixedToolbar } from '@/components/ui/fixed-toolbar';
import { H1Element, H2Element, H3Element } from '@/components/ui/heading-node';
import { MarkToolbarButton } from '@/components/ui/mark-toolbar-button';
import { ToolbarButton } from '@/components/ui/toolbar';

const initialValue: Value = [
  {
    children: [{ text: 'Title' }],
    type: 'h3',
  },
  {
    children: [{ text: 'This is a quote.' }],
    type: 'blockquote',
  },
  {
    children: [
      { text: 'With some ' },
      { bold: true, text: 'bold' },
      { text: ' text for emphasis!' },
    ],
    type: 'p',
  },
];

export default function App() {
  const editor = usePlateEditor({
    plugins: [
      BoldPlugin,
      ItalicPlugin,
      UnderlinePlugin,
      H1Plugin.withComponent(H1Element),
      H2Plugin.withComponent(H2Element),
      H3Plugin.withComponent(H3Element),
      BlockquotePlugin.withComponent(BlockquoteElement),
    ],
    value: () => {
      const savedValue = localStorage.getItem('installation-react-demo');
      return savedValue ? JSON.parse(savedValue) : initialValue;
    },
  });

  return (
    <Plate
      editor={editor}
      onChange={({ value }) => {
        localStorage.setItem('installation-react-demo', JSON.stringify(value));
      }}
    >
      <FixedToolbar className="flex justify-start gap-1 rounded-t-lg">
        <ToolbarButton onClick={() => editor.tf.h1.toggle()}>H1</ToolbarButton>
        <ToolbarButton onClick={() => editor.tf.h2.toggle()}>H2</ToolbarButton>
        <ToolbarButton onClick={() => editor.tf.h3.toggle()}>H3</ToolbarButton>
        <ToolbarButton onClick={() => editor.tf.blockquote.toggle()}>Quote</ToolbarButton>
        <MarkToolbarButton nodeType="bold" tooltip="Bold (⌘+B)">B</MarkToolbarButton>
        <MarkToolbarButton nodeType="italic" tooltip="Italic (⌘+I)">I</MarkToolbarButton>
        <MarkToolbarButton nodeType="underline" tooltip="Underline (⌘+U)">U</MarkToolbarButton>
        <div className="flex-1" />
        <ToolbarButton
          className="px-2"
          onClick={() => editor.tf.setValue(initialValue)}
        >
          Reset
        </ToolbarButton>
      </FixedToolbar>
      <EditorContainer>
        <Editor placeholder="输入您精彩的内容..." />
      </EditorContainer>
    </Plate>
  );
}
<ComponentPreview name="installation-next-demo" />
