Rxjs debounce on react text input component

Question

I have the following react component

Answer 1

You will need to cretae observable from change events(for example using Subject) and then debounce on that.

Here is the fully featured example for you:

class Search extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      search: '',
      debounced: '',
    };
    this.onSearch$ = new Rx.Subject();
    this.onSearch = this.onSearch.bind(this);
  }
  componentDidMount(){
    this.subscription = this.onSearch$
      .debounceTime(300)
      .subscribe(debounced => this.setState({ debounced }));
  }
  
  componentWillUnmount() {
    if (this.subscription) {
      this.subscription.unsubscribe();
    }
  }
  
  onSearch(e) {
    const search = e.target.value;
    this.setState({ search });
    this.onSearch$.next(search);
  }

  render() {
    const { search, debounced } = this.state;
    return (
      

        
        
debounced value: {debounced}
      
    );
  }
}

ReactDOM.render(
  ,
  document.getElementById('root')
);
