Can a dynamic component be assigned to the <Route> element in react-router-dom?

Exploring the concept of dynamically picking and rendering components:

import CompA  from './CompA';
import CompB  from './CompB';

var componentSet = {
 'compa': CompA,
 'compb': CompB
}

var type = 'compa' 
var TargetComp = componentSet[type];
...
return <TargetComp /> 

However, encountered a roadblock when attempting to combine it with the <Route> component:

class DynamicRoute extends Component {
    render() {
        return (
            <Route path="/compa" render={()=> <TargetComp /> }/>
        );
    }
}
// Error message:
// Content.render(): A valid React element (or null) must be returned.- 
// You may have returned undefined, an array or some other invalid object.

Any assistance on this matter would be greatly appreciated!

Answer №1

Can this be applied to version 4? My usual approach involves utilizing the component prop instead of render. Do you think this would be effective in this scenario?

<Route path="/compA" component={TargetComp}/>

Answer №2

If you need to access route properties within the component (such as match, location, or history like using this.props.history in the component's code) that is rendered through Route, you can pass props into the component like this:

<Route path="/componentA" component={(props) => (<ComponentA {...props} myProp={this.state.myProp} />) } />
