本指南将逐步引导您在项目中构建 Plate 编辑器。
<Steps>首先在项目中添加核心 Editor 组件:
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。
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>
);
}
通过文本格式化功能增强编辑器。添加 Basic Nodes Kit、FixedToolbar 和 MarkToolbarButton 组件:
npx shadcn@latest add @plate/basic-nodes-kit @plate/fixed-toolbar @plate/mark-toolbar-button
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。
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>
);
}
通过自定义组件引入标题和引用块等块级元素。
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>
);
}
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:
npx shadcn@latest add @plate/editor-basic
这将为您处理大部分样板代码。 </Callout>
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。
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>
);
}
恭喜!您已在项目中构建了基础的 Plate 编辑器。
