React Router only working some times - reactjs

Question

I am currently experimenting with the use of React Router on the website I am building. I came across the use of React Router in order to navigate through my website, and also do other things like read parameter values etc. However, I find it to be slightly confusing. You see, on my administrator login page, the router only works some times - but I haven't really figured out when and when not. I am using this.props.history.push('/admin/dashboard'), which I believe is the correct way of doing it. This is currently my setup in index.js where i have all my routes:
import React from 'react';
import ReactDOM from 'react-dom';
import registerServiceWorker from './registerServiceWorker';
import './css-styling/styling.css'
import Frontpage from './Frontpage';
import { BrowserRouter, Route, Router, Switch, Link, NavLink } from 'react-router-dom';
import AdminLogin from './Admin-Login';
import AdminWelcome from './Admin-Welcome';
import Authentication from './components/Authentication';
const websiteRoutes = (
<Router history={history}>
<div>
<Switch>
<Route path="/" component={Frontpage} exact={true}/>
<Route path="/admin" component={AdminLogin} exact={true}/>
<Authentication props={this.props}>
<Route path="/admin/welcome" component={AdminWelcome} exact={true}/>
</Authentication>
</Switch>
</div>
</Router>
);
var appRoot = document.getElementById('root');
registerServiceWorker();
ReactDOM.render(websiteRoutes, appRoot);
And each 'component' has its structure like this:
import React from 'react';
import ReactDOM from 'react-dom';
import AdminHeader from './components/Admin-Header';
import AdminPanelLogin from './components/Admin-Panel-Add-News';
import history from './components/History';
class AdminLogin extends React.Component{
render() {
return(
<div>
<AdminHeader />
<AdminPanelLogin />
</div>
);
}
}
export default AdminLogin;
What seem to be the problem here? I have tried a lot of different solutions, without having any luck. One of them was creating this 'global history', which you can see that I have imported in my AdminAddNews class.
What is the correct way of using React Router in my case?
By the way; The history.push happens inside my AdminPanelLogin component, where the code looks like this:
import React from 'react';
import ReactDOM from 'react-dom';
import { Icon, Input, Button, Message } from 'semantic-ui-react';
import {auth} from './Firebase';
import {NotificationContainer, NotificationManager} from 'react-notifications';
import { withRouter, Redirect } from 'react-router-dom';
import history from './components/History';
class AdminLogin extends React.Component{
constructor(props){
super(props);
this.handleLogin = this.handleLogin.bind(this);
this.clickLogin = this.clickLogin.bind(this);
this.performLogin = this.performLogin.bind(this);
}
handleLogin(e){
this.setState({
[e.target.name]: e.target.value
});
}
clickLogin(e){
e.preventDefault();
auth.signInWithEmailAndPassword(this.state.email, this.state.password).then(() => {
this.props.history.push('/admin/dashboard');
}).catch((error)=> {
})
}
render() {
return (
<HTMLGOESHERE>
);
}
}
export default AdminLogin;

Answer 1

Few things, that you need to correct,
First: In your Routes you have passed history but you have not created a custom history anywhere. You can simply use BrowserRouter for now.
Second: Write your authentication component as Wrapper to your Routes instead of using your Routes as children to it
Authentication:
const PrivateRoute = (props) => {
const userKey = Object.keys(window.localStorage)
.filter(it => it.startsWith('firebase:authUser'))[0];
const user = userKey ? JSON.parse(localStorage.getItem(userKey)) : undefined;
if (user) {
return <Route {...props} />
} else {
return <Redirect to='/admin'/>
}
}
export default PrivateRoute;
Now you Routes can be
import { BrowserRouter as Router, Route, Router, Switch } from 'react-router-dom';
import Authentication from './Authentication';
const websiteRoutes = (
<Router>
<div>
<Switch>
<Route path="/" component={Frontpage} exact={true}/>
<Route path="/admin" component={AdminLogin} exact={true}/>
<Authentication path="/admin/welcome" component={AdminWelcome} exact={true}/>
</Switch>
</div>
</Router>
);
Apart from this check how to Programmatically Navigate with react-router

Answer 2

Actually, you have to use browserHistory, which is a function of react-router.I hope following snippet will help you,
Import react-router in your index.js
import {Router, Route, browserHistory} from 'react-router';
ReactDOM.render(
<Router history={browserHistory} >
<Route path="/admin/somethingZero" component={somethingZero} />
<Route path="/admin/somethingOne" component={somethingOne}/>
</Router> , document.getElementById("root")
)
you can navigate between the components, by using browserHistory.push function
clickLogin(){
browserHistory.push('/admin/dashboard')
}
