Nesting routes and dynamically routing in React-router v4

Answer 1

From what I can see of your React Router Design, you seem to be using React router version 4

In that case you can specify the route in the Component Itself, and make use of withRouter to do a dynamic redirect like

return (<div>
        <Router>
          <div>

            <Route path='/login' component={LoginPage}/>
            <EnsureLoggedInContainer/>
          </div>
        </Router>
      </div>
);

and

import React from 'react';
import { connect } from "react-redux";
import {withRouter} from "react-router";

class EnsureLoggedInContainer extends React.Component
{
    componentDidMount() {
        if ( !this.props.isLoggedIn )
        {
            this.props.history.push('/login');

        }
    }

    render() {
        // console.log(this.props);
        if ( this.props.isLoggedIn )
        {
            return <Route path='/abc' component={abc} />
        }
        else
        {
            return null;
        }
    }


}
const mapStateToProps = (state,ownProps) => {
    return{
        isLoggedIn : state.isLoggedIn,
        // currentURL : this.props
    }
}

export default connect(mapStateToProps)(withRouter(EnsureLoggedInContainer));
