# Usage

Install library via `npm`

`npm install react-native-draggable-board`

First you need to build `RowRepository` with data:

```js
const data = [
  {
    id: 1,
    name: 'Column1',
    rows: [
      { id: 1, name: 'Item1' },
      { id: 2, name: 'Item2' },
      { id: 3, name: 'Item3' },
      { id: 4, name: 'Item4' },
      { id: 5, name: 'Item5' },
      { id: 6, name: 'Item6' },
      { id: 7, name: 'Item7' },
      { id: 8, name: 'Item8' }
    ]
  },
  {
    id: 2,
    name: 'Column2',
    rows: [
      { id: 9, name: 'Item9' },
      { id: 10, name: 'Item10' }
    ]
  }
];
const rowRepository = new RowRepository(data);
```

If you need to fetch data asynchronously, you can initialize empty
repository and update it with data later:

```js
const rowRepository = new RowRepository(data);
rowRepository.updateData(data);
```

Then you can render the `Board`:

```jsx
  <Board
    style={styles.board}
    rowRepository={this.state.rowRepository}
    renderRow={this.renderRow.bind(this)}
    renderColumnWrapper={this.renderColumnWrapper.bind(this)}
    open={this.onOpen.bind(this)}
    onDragEnd={this.onDragEnd.bind(this)}
  />
```
