I've been having some trouble with react router (i'm using version^4.0.0).
this is my index.js
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import './index.css';
import { Router, Route, Link, browserHistory } from 'react-router';
ReactDOM.render(
<Router history={browserHistory} >
<Route path="/" component={App} />
</Router>,
document.getElementById('root')
);
the App.js is just anything. i'm posting the basic one here, cause it's not the problem (i believe)
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
class App extends Component {
render() {
return (
<div className="App">
<div className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<h2>Welcome to React</h2>
</div>
<p className="App-intro">
To get started, edit <code>src/App.js</code> and save to reload.
</p>
</div>
);
}
}
export default App;
and this is what happens when i check the console log
Router.js:43 Uncaught TypeError: Cannot read property 'location' of undefined
at new Router (Router.js:43)
at ReactCompositeComponent.js:295

oh, and this is the package.json just in case
{
"name": "teste2",
"version": "0.1.0",
"private": true,
"dependencies": {
"react": "^15.4.2",
"react-dom": "^15.4.2",
"react-router": "^4.0.0"
},
"devDependencies": {
"react-scripts": "0.9.5"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
i've been checking this on other places, but i didn't find a way to solve it.
Thank you guys very much for your patience and help!!
This question is related to
javascript
json
reactjs
react-router
Replace
import { Router, Route, Link, browserHistory } from 'react-router';
With
import { BrowserRouter as Router, Route } from 'react-router-dom';
It will start working. It is because react-router-dom exports BrowserRouter
so if you need want use this code )
import { useRoutes } from "./routes";
import { BrowserRouter as Router } from "react-router-dom";
export const App = () => {
const routes = useRoutes(true);
return (
<Router>
<div className="container">{routes}</div>
</Router>
);
};
// ./routes.js
import { Switch, Route, Redirect } from "react-router-dom";
export const useRoutes = (isAuthenticated) => {
if (isAuthenticated) {
return (
<Switch>
<Route path="/links" exact>
<LinksPage />
</Route>
<Route path="/create" exact>
<CreatePage />
</Route>
<Route path="/detail/:id">
<DetailPage />
</Route>
<Redirect path="/create" />
</Switch>
);
}
return (
<Switch>
<Route path={"/"} exact>
<AuthPage />
</Route>
<Redirect path={"/"} />
</Switch>
);
};
I've tried everything suggested here but didn't work for me. So in case I can help anyone with a similar issue, every single tutorial I've checked is not updated to work with version 4.
Here is what I've done to make it work
import React from 'react';
import App from './App';
import ReactDOM from 'react-dom';
import {
HashRouter,
Route
} from 'react-router-dom';
ReactDOM.render((
<HashRouter>
<div>
<Route path="/" render={()=><App items={temasArray}/>}/>
</div>
</HashRouter >
), document.getElementById('root'));
That's the only way I have managed to make it work without any errors or warnings.
In case you want to pass props to your component for me the easiest way is this one:
<Route path="/" render={()=><App items={temasArray}/>}/>
