Fed up with writing a ton of Redux boilerplate just to make a form input editable?
|
||
|
||
There’s a better alternative: Gun.js. It makes state synchronization and persistence super easy.
|
||
|
||
First, initialize Gun with options that make sure the state is synced with localStorage only (not with peers).
|
||
```jsx
|
||
const State = new Gun({
|
||
localStorage: true,
|
||
file: 'State.local', // localStorage key
|
||
multicast: false, // on Node.js, Gun would sync with local area network peers over multicast :)
|
||
peers: [] // this time we don't want to sync with other users
|
||
}).get('state');
|
||
```
|
||
|
||
Then create a React component that uses the state:
|
||
|
||
```jsx
|
||
class CommentForm extends React.Component {
|
||
constructor() {
|
||
super();
|
||
this.state = {comment:''};
|
||
}
|
||
componentDidMount() {
|
||
State.get('comment').on(comment => this.setState({comment}));
|
||
}
|
||
|
||
onInput(e) {
|
||
State.get('comment').put(e.target.value);
|
||
}
|
||
|
||
render() {
|
||
return (
|
||
<form class="box">
|
||
<input placeholder="Type something" type="text" value={this.state.comment} onChange={e => this.onInput(e)} />
|
||
</form>
|
||
);
|
||
}
|
||
}
|
||
```
|
||
|
||
Now you have a comment form that syncs its content across component instances and persists it in localStorage.
|
||
