JavaScript React Router Basics Navigating and Nesting Routes Index Routes and Redirects

parent URL repeating for child Links /courses/courses/courses/courses/courses/css

Everything works.. However each time the child URL is clicked the parent URL repeats itself.

http://localhost:8080/courses/courses/courses/courses/courses/courses/courses/css

        <Route path="courses" component={Courses}>
          <IndexRedirect to="html"/>
          <Route path="html" component={HTML} />
          <Route path="css" component={CSS} />
          <Route path="javascript" component={JavaScript} />
        </Route>
         <ul className="course-nav">
            <li><Link to="courses/html" activeClassName="active">HTML</Link></li>
            <li><Link to="courses/css" activeClassName="active">CSS</Link></li>
            <li><Link to="courses/javascript" activeClassName="active">JavaScript</Link></li>
          </ul>

Solved my own problem. I swapped the initial browserHistory import for the code below.

import React from 'react';
import {Router, Route,  IndexRedirect} from 'react-router';

import { createHistory, useBasename } from "history";
const browserHistory = useBasename(createHistory)({
    basename: "/"
});
