<Callout type="warning" title="前置条件"> 开始之前,请确保您已安装并配置好 [shadcn/ui](https://ui.shadcn.com/docs/installation/next) 和 [Plate UI](/docs/installation/plate-ui)。 </Callout>

本指南将引导您在 Next.js 应用程序中逐步构建 Plate 编辑器。

<Steps>

创建您的第一个编辑器

首先将核心 Editor 组件添加到您的项目中:

bash
npx shadcn@latest add @plate/editor

接下来,创建一个基础编辑器页面。此示例在 EditorContainer 中设置了一个简单的编辑器。

tsx
'use client';

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

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

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

  return (
    <Plate editor={editor}>
      <EditorContainer>
        <Editor placeholder="在这里输入精彩内容..." />
      </EditorContainer>
    </Plate>
  );
}
<Callout type="info"> `usePlateEditor` 创建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

通过文本格式化增强您的编辑器。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、引用等)及其组件,我们将在后续步骤中使用。 </Callout>

更新您的编辑器页面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
'use client';

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 MyEditorPage() {
  const editor = usePlateEditor({
    plugins: [BoldPlugin, ItalicPlugin, UnderlinePlugin], // Add the mark plugins
    value: initialValue,         // Set initial content
  });

  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="Type your amazing content here..." />
      </EditorContainer>
    </Plate>
  );
}
<ComponentPreview name="installation-next-02-marks-demo" height="200px" />

添加基础元素

引入块级元素,如标题和引用块,并使用自定义组件。

tsx
'use client';

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'; // Generic toolbar button

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 MyEditorPage() {
  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="Type your amazing content here..." />
      </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)` 将组件注册到各自的插件。这是将 React 组件与 Plate 插件关联的推荐方法。

如需快速开始并预配置常用插件和组件,请使用 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,让我们集成 localStorage 来在客户端保存和加载编辑器的值。

tsx
'use client';

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 MyEditorPage() {
  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-next-demo');
      return savedValue ? JSON.parse(savedValue) : initialValue;
    },
  });

  return (
    <Plate
      editor={editor}
      onChange={({ value }) => {
        localStorage.setItem('installation-next-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="Type your amazing content here..." />
      </EditorContainer>
    </Plate>
  );
}
<ComponentPreview name="installation-next-demo" />
