Material-UI's Tabs integration with react router 4?

Another solution (https://codesandbox.io/s/l4yo482pll) with no handlers nor HOCs, just pure react-router and material-ui components:

import React, { Fragment } from "react";
import ReactDOM from "react-dom";
import Tabs from "@material-ui/core/Tabs";
import Tab from "@material-ui/core/Tab";
import { Switch, Route, Link, BrowserRouter, Redirect } from "react-router-dom";

function App() {
  const allTabs = ['/', '/tab2', '/tab3'];

  return (
    <BrowserRouter>
      <div className="App">
        <Route
          path="/"
          render={({ location }) => (
            <Fragment>
              <Tabs value={location.pathname}>
                <Tab label="Item One" value="/" component={Link} to={allTabs[0]} />
                <Tab label="Item Two" value="/tab2" component={Link} to={allTabs[1]} />
                <Tab
                  value="/tab3"
                  label="Item Three"
                  component={Link}
                  to={allTabs[2]}
                />
              </Tabs>
              <Switch>
                <Route path={allTabs[1]} render={() => <div>Tab 2</div>} />
                <Route path={allTabs[2]} render={() => <div>Tab 3</div>} />
                <Route path={allTabs[0]} render={() => <div>Tab 1</div>} />
              </Switch>
            </Fragment>
          )}
        />
      </div>
    </BrowserRouter>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

My instructor helped me with using React Router 4.0's withRouter to wrap the Tabs component to enable history methods like so:

import React, {Component} from "react";
import {Tabs, Tab} from 'material-ui';
import { withRouter } from "react-router-dom";

import Home from "./Home";
import Portfolio from "./Portfolio";

class NavTabs extends Component {

 handleCallToRouter = (value) => {
   this.props.history.push(value);
 }

  render () {
     return (
      <Tabs
        value={this.props.history.location.pathname}
        onChange={this.handleCallToRouter}
        >
        <Tab
          label="Home"
          value="/"
        >
        <div>
           <Home />
        </div>
        </Tab>
        <Tab
          label="Portfolio"
          value="/portfolio"
            >
          <div>
            <Portfolio />
          </div>
        </Tab>
      </Tabs>           
    )
  }
}

export default withRouter(NavTabs)  

Simply add BrowserRouter to index.js and you're good to go.

The error you are seeing from material-ui is because it expects to have a <Tab> component rendered as direct child of <Tabs> component.

Now, here is a way that I've found to integrate the link into the <Tabs> component without loosing the styles:

import React, {Component} from 'react';
import {Tabs, Tab} from 'material-ui/Tabs';
import {Link} from 'react-router-dom';

export default class MyComponent extends Component {
    render() {
        const {location} = this.props;
        const {pathname} = location;

        return (
            <Tabs value={pathname}>
                <Tab label="First tab" containerElement={<Link to="/my-firs-tab-view" />} value="/my-firs-tab-view">
                    {/* insert your component to be rendered inside the tab here */}
                </Tab>
                <Tab label="Second tab" containerElement={<Link to="/my-second-tab-view" />} value="/my-second-tab-view">
                    {/* insert your component to be rendered inside the tab here */}
                </Tab>
            </Tabs>
        );
    }
}

To manage the 'active' property for the tabs, you can use the value property in the <Tabs> component and you also need to have a value property for each tab, so when both of the properties match, it will apply the active style to that tab.
