TypeScript + redux-first-router expected string class/function

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object. Check the render method of `App`

When that runtime error occurred, chances is the default is forgotten when importing Link since there is no TypeScript definition for redux-first-router-link yet.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { Provider, connect } from 'react-redux';
const Link = require('redux-first-router-link');

To fix:

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { Provider, connect } from 'react-redux';
const Link = require('redux-first-router-link').default;

Happy coding!
