Introducing the New React Wrapper

With Handsontable 15.0, we're rolling out a brand-new React wrapper designed for functional programming. It focuses on type safety, idiomatic React usage, and developer experience. Named react-wrapper, you can find it in our GitHub monorepo (opens new window) or install it directly from npm (opens new window).

This guide will help you migrate your existing @handsontable/react class-based wrapper to @handsontable/react-wrapper.

Key changes

  • Removal of the settings prop in favor of direct prop passing
  • Updated syntax for defining custom renderers and editors
  • Introduction of the useHotEditor hook for creating function-based custom editors

TIP

The class-based @handsontable/react wrapper is still around and fully supported. So if you're into class-based editor and renderer components, you can keep using it.

Warning messages

To assist you in the migration process, @handsontable/react-wrapper provides warning messages to help identify and update deprecated practices:

Obsolete Renderer Warning:
Providing a component-based renderer using `hot-renderer`-annotated component is no longer supported. 
Pass your component using `renderer` prop of the `HotTable` or `HotColumn` component instead.

Obsolete Editor Warning:
Providing a component-based editor using `hot-editor`-annotated component is no longer supported. 
Pass your component using `editor` prop of the `HotTable` or `HotColumn` component instead.

Migration steps

1. Removal of settings property

The settings property has been removed. Configuration options must now be passed directly to the HotTable component.

@handsontable/react:

const settings = { rowHeaders: true, colHeaders: true };

<HotTable settings={settings} />

@handsontable/react-wrapper:

<HotTable 
  rowHeaders={true} 
  colHeaders={true}
  // Other options are available as props
/>

2. Custom renderer changes

Custom renderers should now be provided using the renderer prop of either HotTable or HotColumn.

@handsontable/react:

<HotColumn width={250}>
  <RendererComponent hot-renderer />
</HotColumn>

@handsontable/react-wrapper:

<HotColumn width={250} renderer={RendererComponent} />

Additionally, custom renderers now receive props with proper TypeScript definitions:

import { HotRendererProps } from '@handsontable/react-wrapper';

const MyRenderer = (props: HotRendererProps) => {
  const { value, row, col, cellProperties } = props;
  return (
    <div style={{ backgroundColor: cellProperties.readOnly ? '#f0f0f0' : '#fff' }}>
      {`${value.name}: ${value.value} at (${row}, ${col})`}
    </div>
  );
};

TIP

If you’re using the renderer option for JavaScript function-based renderers, don’t worry - you can still use them! Just define them under the hotRenderer key instead of renderer.

3. Custom editor changes

Custom editors have changed a lot - they've moved from class-based to function-based components, now using the new useHotEditor hook.

3.1. Replace the class declaration with a function:

@handsontable/react:

class EditorComponent extends BaseEditorComponent {
  // ...
}

@handsontable/react-wrapper:

const EditorComponent = () => {
  // ...
};

3.2. Implement the useHotEditor hook

Replace the BaseEditorComponent methods with the useHotEditor hook:

import { useHotEditor } from '@handsontable/react-wrapper';

const EditorComponent = () => {
  const { value, setValue, finishEditing } = useHotEditor({
    onOpen: () => {
      // Open logic
    },
    onClose: () => {
      // Close logic
    },
  });

  // Component logic here
};

3.3. Update the component structure

Replace the render method with the function component's return statement:

return (
  <div>
    <button onClick={finishEditing}>Apply</button>
  </div>
);

3.4. Update HotColumn Usage

Just like with renderers, custom editors now need to be provided using the editor prop on either HotTable or HotColumn.

@handsontable/react:

<HotColumn width={250}>
  <EditorComponent hot-editor />
</HotColumn>

@handsontable/react-wrapper:

<HotColumn width={250} editor={EditorComponent} />

TIP

If you’re using the editor option for JavaScript class-based editors, you can still use them. Just define them under the hotEditor key instead of editor.
