getting this exception

Not able to find the mistake i made any help in this regard will be greatly appreciated please find my package.json entries

"react": "^15.6.2",
"react-dimensions": "^1.3.0",
"react-dom": "^15.6.2",
"react-virtualized-select": "3.1.0",

Answer 1

The problem is with the line:

var VirtualizedSelect = require('react-virtualized-select');

Which needs to be changed to:

var VirtualizedSelect = require('react-virtualized-select').default;

The error message is because what's being imported isn't a React component, and seemingly has to do with the way that the export default in React Virtualized Select's source has been traspiled into ES5.

Answer 2

I think you forgot to add the render method for the class component.

checkout the code below

  var React = require('react'); var ReactDOM = require('react-dom'); var VirtualizedSelect = require('react-virtualized-select'); module.exports = React.createClass({ componentName: 'Search', getDefaultProps() { return {}; }, getInitialState() { return { error: false, authenticated: false, visible: true, data: null, showAccountSelection: false, selected: null, search: '', optionPartnerList: [] }; }, componentDidMount () { var qS = queryString.parse(location.search); if (qS && qS.search) { this.setState({search: qS.search, visible: true}); } this._unsubscribe = AppStore.listen(Utils.createRefluxComponentDispatcher(this)); }, componentDidUpdate: function () { if (this.refs.inputSearch) { this.refs.inputSearch.focus(); this.refs.inputSearch.select() } }, componentWillUnmount () { this._unsubscribe(); } render() { return ( <div style={{float:'left'}} className="search-div"> {this.searchIcon()} <div className="overlay" style={overlayStyle}> {closeButton} <div className="global-search center-content-wrapper" style={style}> <form id="searchFormComponent" ref={function(){$('#searchFormComponent').show('fast')}} className="global-search" onSubmit={this.handleClick} style={{height: '500px'}}> {this.errorRender()} <div className="f-row f-center"> <input id="searchbox" type="text" ref="inputSearch" className="form-control f-9 searchbox" placeholder="SEARCH FOR ACCOUNT" required style={{marginBottom:'1px'}} disabled={componentDisabled} defaultValue={this.state.search}> </input> <VirtualizedSelect options={self.optionPartnerList} onChange={(selectValue) => this.setState({ selectValue })} value={this.state.selectValue} /> <button id="searchbutton" className="btn btn-lg btn-primary btn-block t-font f-1" disabled={componentDisabled} onClick={this.handleClick} style={{ paddingLeft: '4px',paddingRight: '4px', fontSize:'1.1em',marginLeft:'4px'}}> {buttonIcon} </button> </div> </form> </div> </div> </div> ); } } });
