Migrating from Slate to Plate

Migrating from Slate to Plate

Learn how to migrate from Slate to Plate.

Plate is built on top of Slate, so migrating from a pure Slate implementation to Plate is relatively straightforward. This guide will help you transition your Slate-based editor to Plate.

1. Install Plate

First, install the necessary Plate packages. If you're new to Plate, you might want to start by reading the Introduction to get an overview of the library.

npm install @udecode/plate

2. Replace Slate Imports

Replace your Slate imports with Plate imports. Plate re-exports most Slate types and functions:

// Before
import { createEditor } from 'slate';
import { Slate, Editable, withReact } from 'slate-react';
 
// After
import { createPlateEditor, Plate, PlateContent } from '@udecode/plate/react';

3. Create a Plate Editor

Replace createEditor, withHistory and withReact with createPlateEditor:

// Before
const editor = useMemo(() => withReact(withHistory(createEditor()))), []);
 
// After
const editor = createPlateEditor({
  value,
  plugins: [
    // Additional plugins here
  ],
});

For more details on editor configuration, check out the Editor Configuration guide.

4. Replace Slate and Editable Components

Replace the Slate and Editable components with Plate's Plate component:

// Before
<Slate editor={editor} value={value}>
  <Editable className="p-4" />
</Slate>
 
// After
<Plate editor={editor}>
  <PlateContent className="p-4" />
</Plate>

5. Convert Custom Elements and Leaves

For custom elements and leaves, create Plate plugins:

// Before
const renderElement = useCallback(({ attributes, children, element }) => {
  switch (element.type) {
    case 'paragraph':
      return <p {...attributes}>{children}</p>;
    // ... other cases
  }
}, []);
 
// After
import { withCn, type PlateElement } from '@udecode/plate/react';
 
const ParagraphElement = withRef<typeof PlateElement>(
  ({ children, className, ...props }, ref) => {
    return (
      <PlateElement
        asChild
        className={cn('py-1', className)}
        ref={ref}
        {...props}
      >
        <p>{children}</p>
      </PlateElement>
    );
  }
);
 
const ParagraphPlugin = createPlatePlugin({
  key: 'p',
  node: {
    isElement: true,
    type: 'paragraph',
    component: ParagraphElement,
  },
});

Learn more about creating plugins in the Plugin Configuration guide and Plugin Components guide.

6. Convert Slate Plugins to Plate Plugins

If you have custom Slate plugins, convert them to Plate plugins:

// Before
const withMyPlugin = (editor) => {
  const { insertText } = editor;
  editor.insertText = (text) => {
    // Custom logic
    insertText(text);
  };
  return editor;
};
 
// After
const MyPlugin = createPlatePlugin({
  key: 'myPlugin',
  extendEditor: ({ editor }) => {
    const { insertText } = editor;
    editor.insertText = (text) => {
      // Custom logic
      insertText(text);
    };
    return editor;
  },
});

For more information on working with the plugin context, see the Plugin Context guide.

7. Update Event Handlers

Update your event handlers to use Plate's plugin system:

// Before
const onKeyDown = (event) => {
  if (event.key === 'Tab') {
    // Handle tab
  }
};
 
// After
const TabPlugin = createPlatePlugin({
  key: 'tab',
  handlers: {
    onKeyDown: ({ editor, event }) => {
      if (event.key === 'Tab') {
        // Handle tab
      }
    },
  },
});

Alternatively, you can use Plate's powerful shortcuts system:

const TabPlugin = createPlatePlugin({
  key: 'tab',
  shortcuts: {
    indent: {
      handler: ({ editor }) => {
        // Handle tab
      },
      keys: ['Tab'],
    },
  },
});

For more details on using shortcuts, check out the Plugin Shortcuts guide.

8. Adapt to Plate's API

Familiarize yourself with Plate's API and use its utilities and hooks:

// Using Plate's transforms
editor.tf.toggle.mark({ key: 'bold' });
 
// Using Plate's debug API
editor.api.debug.log('Hello, Plate!');

For a comprehensive list of editor methods, see the Editor Methods guide.

9. Leverage Plate's Built-in Plugins

Plate comes with many built-in plugins that you can see in the sidebar. Use them to quickly add functionality:

import { BoldPlugin, ItalicPlugin, UnderlinePlugin } from '@udecode/plate/react';
 
const plugins = [
  BoldPlugin,
  ItalicPlugin,
  UnderlinePlugin,
  // ... other plugins
];
 
const editor = createPlateEditor({ plugins });

10. Testing and Refinement

After migrating, thoroughly test your editor to ensure all functionality works as expected. Refine and optimize your implementation using Plate's features and best practices.
