The prop `history` is marked as required in `Router`, but its value is `undefined`. in Router

Question

I am new to ReactJs. This is my code:

var React = require(\'react\');
var ReactDOM = require(\'react-dom\');
var {Route, Router, IndexRoute, hashHistory} = requ         


        

Answer 1

The below works for me with "react-router@^3.0.5":

package.json:

"react-dom": "^16.6.0",
"react-router": "^3.0.5"

index.js:

import { render } from 'react-dom'
import { App } from './components/App'
import { NotFound404 } from './components/NotFound404'
import { Router, Route, hashHistory } from 'react-router'

render(
    <Router history={hashHistory}>
        <Route path='/' component={App} />
        <Route path='*' component={NotFound404} />
    </Router>,
    document.getElementById('root')
)

Answer 2

Which version of React Router are you using? Router version 4 changed from passing in the browserHistory class to passing an instance of browserHistory, see the code example in the new docs.

This has been catching lots people who automatically upgrade; a migration document will be out 'any day now'.

You want to add this to the top:

import { createBrowserHistory } from 'history'

const newHistory = createBrowserHistory();

and

<Router history={newHistory}/>

I also write a Login practice. And also meet the same question like you. After a day struggle, I found that only this.props.history.push('/list/') can make it instead of pulling in a lot of plugins. By the way, the react-router-dom version is ^4.2.2. Thanks!

handleSubmit(e){
    e.preventDefault();
    this.props.form.validateFieldsAndScroll((err,values)=>{
        if(!err){
            this.setState({
                visible:false
            });
            this.props.form.resetFields();
            console.log(values.username);
            const path = '/list/';
            this.props.history.push(path);
        }
    })
}

If you want to have multiple routes you can use switch like this,

import {Switch} from 'react-router'; 

then

<BrowserRouter>
     <Switch>
         <Route exact path="/" component={TodoComponent} />
         <Route path="/about" component={About} />
     </Switch>
</BrowserRouter>

If you are using react-router v4 you need to install react-router-dom as well. After that, import BrowserRouter from react-router-dom and switch Router for BrowserRouter. It seems that v4 change several things. Also, the react-router documentation is outdated. This is my working code:

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter, Route } from 'react-router-dom'
import App from './components/App';

ReactDOM.render((
     <BrowserRouter>
          <Route path="/" component={App}/>
     </BrowserRouter>
     ),
     document.getElementById('root')
);

I got the same problem in ES6, but when I switched to use 'react-router-dom' library, the problem was solved. For all fans of ES6, here we go:

npm install --save react-router-dom

In index.js:

import {HashRouter, Route} from 'react-router-dom';
import App from './App';

ReactDOM.render(
    <HashRouter>
        <Route path="/" component={App}/>
    </HashRouter>
  ,
  document.getElementById('root')
);
