Editor Configuration

Editor Configuration

Learn how to configure and customize the Plate editor.

This guide covers the configuration options for the Plate editor, including basic setup, plugin management, and advanced configuration techniques.

Basic Editor Configuration

To create a basic Plate editor, you can use the createPlateEditor function, or usePlateEditor in a React component:

import { createPlateEditor } from '@udecode/plate-common/react';
 
const editor = createPlateEditor({
  plugins: [ParagraphPlugin, HeadingPlugin],
});

Initial Value

Set the initial content of the editor:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin],
  value: [
    {
      type: 'p',
      children: [{ text: 'Hello, Plate!' }],
    },
  ],
});

Adding Plugins

You can add plugins to your editor by including them in the plugins array:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin, HeadingPlugin, ListPlugin],
});

Max Length

Set the maximum length of the editor:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin],
  maxLength: 100,
});

Advanced Configuration

Id

Set a custom id for the editor:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin],
  id: 'my-custom-editor-id',
});

If defined, you should always pass the id as the first argument in any editor retrieval methods.

Normalization

Control whether the editor should normalize its content on initialization:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin],
  shouldNormalizeEditor: true,
});

Auto-selection

Configure the editor to automatically select a range:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin],
  autoSelect: 'end', // or 'start', or true
});

This is not the same as auto-focus: you can select text without focusing the editor.

Component Overrides

Override default components for plugins:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin, HeadingPlugin],
  override: {
    components: {
      [ParagraphPlugin.key]: CustomParagraphComponent,
      [HeadingPlugin.key]: CustomHeadingComponent,
    },
  },
});

Plugin Overrides

Override specific plugin configurations:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin, HeadingPlugin],
  override: {
    plugins: {
      [ParagraphPlugin.key]: {
        options: {
          customOption: true,
        },
      },
    },
  },
});

Disable Plugins

Disable specific plugins:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin, HeadingPlugin, ListPlugin],
  override: {
    enabled: {
      [HistoryPlugin.key]: false,
    },
  },
});

Overriding Plugins

You can override core plugins or previously defined plugins by adding a plugin with the same key. The last plugin with a given key wins:

const CustomParagraphPlugin = createPlatePlugin({
  key: 'p',
  // Custom implementation
});
 
const editor = createPlateEditor({
  plugins: [ParagraphPlugin, CustomParagraphPlugin],
});

Root Plugin

From the root plugin, you can configure any plugin:

const editor = createPlateEditor({
  plugins: [ParagraphPlugin, HeadingPlugin],
  rootPlugin: (plugin) =>
    plugin.configurePlugin(LengthPlugin, {
    options: {
        maxLength: 100,
      },
    }),
});

Typed Editor

createPlateEditor will automatically infer the types for your editor from the value and the plugins you pass in. For explicit type creation, you can use createTPlateEditor:

Plugins Type

const editor = createTPlateEditor<Value, typeof TablePlugin | typeof LinkPlugin>({
  plugins: [TablePlugin, LinkPlugin],
});
 
// Usage
editor.tf.insert.tableRow()

Value Type

For more complex editors, you can define your types in a separate file (e.g., plate-types.ts):

import type { TElement, TText } from '@udecode/plate-common';
import type { TPlateEditor } from '@udecode/plate-common/react';
 
// Define custom element types
interface ParagraphElement extends TElement {
  align?: 'left' | 'center' | 'right' | 'justify';
  children: RichText[];
  type: typeof ParagraphPlugin.key;
}
 
interface ImageElement extends TElement {
  children: [{ text: '' }]
  type: typeof ImagePlugin.key;
  url: string;
}
 
// Define custom text types
interface FormattedText extends TText {
  bold?: boolean;
  italic?: boolean;
}
 
export type MyRootBlock = ParagraphElement | ImageElement;
 
// Define the editor's value type
export type MyValue = MyRootBlock[];
 
// Define the custom editor type
export type MyEditor = TPlateEditor<MyValue, typeof TablePlugin | typeof LinkPlugin>;
 
export const useMyEditorRef = () => useEditorRef<MyEditor>();
 
// Usage
const value: MyValue = [{
  type: 'p',
  children: [{ text: 'Hello, Plate!' }],
}]
 
const editorInferred = createPlateEditor({
  plugins: [TablePlugin, LinkPlugin],
  value,
});
 
// or 
const editorExplicit = createTPlateEditor<MyValue, typeof TablePlugin | typeof LinkPlugin>({
  plugins: [TablePlugin, LinkPlugin],
  value,
});

Benefits

We strongly recommend using typed editors for the following reasons:

  1. Type Safety: The editor enforces the structure of your document, preventing invalid operations.
  2. Autocomplete: Your IDE can provide better autocomplete suggestions based on your custom types.
  3. Refactoring: Changing types in one place will highlight necessary changes throughout your codebase.
  4. Documentation: Types serve as a form of self-documentation for your editor's structure and capabilities.
