# How To Use

Install

```console
npm i react-native-node-view
```

Import

```jsx
import NodeView from 'react-native-node-view';
```

## Examples

Simple

```jsx
<NodeView
	nodesGroups={[
		{ nodes: [{ id: '1', lineTo: ['2', '3'], onPress: id => console.log(id) }] },
		{ nodes: [{ id: '2' }, { id: '3' }] },
	]}
/>
```

Inside view

```jsx
<View style={{ width: 300, height: 300, alignSelf: 'center', borderWidth: 1, borderRadius: 10, borderColor: 'gray' }}>
	<NodeView
		nodesGroups={[
			{ nodes: [{ id: '1', lineTo: ['2', '3'], onPress: id => console.log(id) }] },
			{ nodes: [{ id: '2' }, { id: '3' }] },
		]}
	/>
</View>
```

With delete operation

```jsx
const [nodesGroups, setNodesGroups] = useState([
	{
		nodes: [{ id: '1', lineTo: ['2', '3'], onPress: (id: string) => console.log(id) }],
	},
	{
		nodes: [{ id: '2' }, { id: '3' }],
	},
]);

return (
	<View
		style={{
			flex: 1,
			justifyContent: 'center',
			backgroundColor: 'white',
		}}>
		<NodeView
			enablePan={true}
			enableZoom={true}
			containerStyle={{ borderWidth: 0 }}
			onDeleteNode={(id, oldState, newState) => setNodesGroups(newState)}
			nodesGroups={nodesGroups}
		/>
	</View>
);
```
