React Native DnD Board

A drag and drop Kanban board for React Native using Reanimated (V2) and React Native Gesture Handler.

Installation

Step 1:

Install Reanimated V2.

Step 2:

Install React Native Gesture Handler.

Make sure your MainActivity.java was updated by follow all Android instructions.

React Native Gesture Handler IMPORTANT NOTE: If you're using wix/react-native-navigation, please wrap your board screen using gestureHandlerRootHOC (View RNGH docs for more details). If not do it, your board won't work.

Step 3:

Install this package using npm or yarn

with npm:

npm install react-native-drag-dnd-board

with yarn:

yarn add react-native-drag-dnd-board

API reference

The package exports a Board component which is the one you'd use to render the dnd board and a Repository class to handle column, row layout.

Board

| Property | Type | Required | Description | | :------------------ | :------------------------------------------------------ | :------: | :---------------------------------------------------------------------- | | repository | Repository | yes | Object that holds data | | renderRow | ({ item, index }) => {} | yes | Function responsible for rendering row item | | renderColumnWrapper | ({ item, index, columnComponent, layoutProps }) => {} | yes | Function responsible for rendering wrapper of the column | | onRowPress | (row) => {} | no | Function invoked when row pressed | | onDragStart | () => {} | no | Function invoked when drag is started | | onDragEnd | (fromColumnId, toColumnId, row) => {} | no | Function invoked when drag is finished | | style | StyleProp | no | Style of the board | | columnWidth | number | no | Initial min column width | | accessoryRight | function\|View | no | Render end of the board. Useful when rendering virtual add more column. | | activeRowStyle | StyleProp | no | A custom style for the row when being dragged. | | activeRowRotation | number | no | Degrees to rotate the row when being dragged. Default is 8. | | xScrollThreshold | number | no | Offset from X to calculate scroll from. Default is 50. | | yScrollThreshold | number | no | Offset from Y for the rows. Default is 50. | | dragSpeedFactor | number | no | When dragging you can accelerate the scrollTo position. Default is 1. |

Repository

Update repository data:

repository.updateData(data);

Handle column data:

repository.addColumn(data);

repository.updateColumn(columnId, data);

repository.deleteColumn(columnId);

Handle row data:

repository.addRow(columnId, data);

repository.updateRow(rowId, data);

repository.deleteRow(rowId);

Get rows with index updated:

const { rows } = repository.getItemsChanged();

Example

Usage

You need to build Repository

import Board, { Repository } from "react-native-dnd-board";

const mockData = [
  {
    id: "1",
    name: "Column 1",
    rows: [
      {
        id: "11",
        name: "Row 1 (Column 1)",
      },
      {
        id: "12",
        name: "Row 2 (Column 1)",
      },
    ],
  },
  {
    id: "2",
    name: "Column 2",
    rows: [
      {
        id: "21",
        name: "Row 1 (Column 2)",
      },
    ],
  },
];

const [repository, setRepository] = useState(new Repository(mockData));

Render the Board

<Board
  repository={repository}
  renderRow={renderCard}
  renderColumnWrapper={renderColumnWrapper}
  onRowPress={onCardPress}
  onDragEnd={onDragEnd}
/>

renderColumnWrapper function

const renderColumnWrapper = ({ item, columnComponent, layoutProps }) => {
  return (
    <View style={styles.column} {...layoutProps}>
      <Text style={styles.columnName}>{item.name}</Text>
      {columnComponent}
    </View>
  );
};

IMPORTANT: You need pass layoutProps to wrapper view props and columnComponent must be rendered inside renderColumnWrapper fuction.

See example for more details.
