Conditional API call and send data in react-select

Answer 1

There are couple of issues:

this.handlePartsType = this.handlePartsType.bind(this); is redundant. Also constructor does not have closing bracket. Select.Async is not supposed to be used to load options based on external value, it loads options when input changes.

Below is rewritten example:

		const partsType = [
		    {value: 'front_parts', label: 'Part Condition-Front'},
		    {value: 'left_parts', label: 'Part Condition-Left'},
		    {value: 'back_parts', label: 'Part Condition-Back'},
		    {value: 'right_parts', label: 'Part Condition-Right'},
		    {value: 'top_bottom_parts', label: 'Part Condition-Top/Bottom'},
		    {value: 'glass', label: 'Glass Condition'},
		    {value: 'electrical_parts', label: 'Electrical Parts'},
		    {value: 'non_electrical_parts', label: 'Non-Electrical Parts'}
		];
    
    // test wrapper for fetch to be removed to talk to backend
    const fetch = () => Promise.resolve({json: () => Promise.resolve([{promptCode: 'test', text: 'Test option'}])})

		const getParts = (partsType) => {
		    return fetch(
			  `http://localhost:4000/${partsType}`,
			  {
			      method: 'get'
			  }
			)
			  .then(response => {
			      if(response.status >= 400){
				  throw new Error("error");
			      }
			      return response.json()
			  })
			  .then(parts => {
			      let partsName = [];


			      for(let part of parts) {
				  partsName.push({value: part.promptCode, label: part.text})
			      }


			      return {options: partsName};
			  })
			  .catch(err => {
			      console.log('could not fetch parts');
			      console.log(err);
			      return {options: []}
			  })

		};

		class Assess extends React.Component {
      state = {
			    partsType:'front_parts'
			};

      handlePartsType = (partsType) => {
        getParts(partsType).then(({options}) =>
          this.setState({partsType, partsOptions: options})
        )
      };
      
      componentDidMount() {
        this.handlePartsType(this.state.partsType);
      }

		render() {
		    return (
		    

			 this.handlePartsType(value)}
			/>
		

		
		    );
		  }
		}

,
  document.getElementById('root')
)
