I am new using react router v4. I have a link that runs a function in the onClick event and then redirects to a specific route.
This is the link:
<Link className={''}
to={'/test'}
onClick={this.testFunction}>To test</Link>
and the test function:
testFunction(event){
e.preventDefault();
// do some things...
this.props.history.push('/test');
}
This works but I need to write both times the "/test" route (in the Link component and in the function).
Is there a way of getting the "to" prop so I don't have to write it twice?
If you use "withRouter" in your component:
import {Link, withRouter} from 'react-router-dom';
...
export default withRouter(TestComponent);
you can access the route's path by using:
this.props.match.path
Use this in your code:
testFunction(event){
e.preventDefault();
// do some things...
this.props.history.push(this.props.match.path);
}
When you use "withRouter" in your component you can access the match, location and history props of the route.

Hope it helps!

Code Sandbox link:
and trying to follow this article
On successful login(/auth/login), the user should be routed to the dashboard(/admin/summary). If the login is successful, I am also storing an access token.
I have a PrivateRoute component for this. The problem is that on successful login, the URL is getting updated but the component is not getting rendered.
PS: about the dashboard, this is a single page application so, the dashboard has topbar, sidebar, and the right content and altogether these things are coupled inside <AdminLayout/>. So, in my AppRouter, I have to render the <AdminLayout/> and just any one component.
All the react and redux code is included in the code sandbox.
Since in your code you create your own history object (it happens in you history.js file, when you call createBrowserHistory()) but doesn't pass it to your Router, nothing happens.
There are 2 possible solutions:
1. Don't create a history object yourself, but use useHistory hook inside your component
Working Demo
With this approach, you should remove history.push from login.actions.js (which imports history) and use history.push in Login.js (which uses useHistory hook):
// login.actions.js
...
loginService.login(userid, password, rememberPassword).then(
(userid) => {
dispatch(success(userid, password, rememberPassword));
// history.push(from); <-- commented out!
},
(error) => { ... }
);
};
...
// Login.js
function handleSubmit(e) {
...
const { from } = {
from: { pathname: "/admin/summary" }
};
history.push(from) // <-- added!
dispatch(loginActions.login(inputs, from));
...
}
useHistory exposes the history object of BrowserRouter (I think this is implied in this official blog post).
2. Create a history object yourself, but pass it to a Router component
Working Demo
This approach would require you to make several changes:
Creating the history object on your own means you become responsible to provide it to a router component, but it can't be a BrowserRouter, but the base Router component (see these Github answers: 1, 2).
Once you import Router (instead of BrowserRouter), you need to get rid of any useLocation and useHistory imports, otherwise you'll get errors.
I also had to unify the history object export and imports, so that it is exported as the default export (i.e., export default history), and it is imported as the default import (i.e., import history from "./history"; instead of import { history } from "./history")
(P.S: this approach can be seen implemented elsewhere on SO, for example here or here (the latter explicitly installs history, but it's not needed in your case).
In an application using react, redux and react-router, I'm using react-router-redux to issue navigation actions. I found that wrapping routes in a component with connect blocks navigation.
I made a sample with CodeSandbox that illustrates the issue: sample.
As is, the navigation doesn't work. However, if in ./components/Routes.jsx, this line:
export default connect(() => ({}), () => ({}))(Routes);
Is replaced by:
export default Routes;
It works.
Any idea how I could use connect in a component that wraps routes without breaking navigation?
See the troubleshooting section in react-redux docs.
If you change Routes.jsx export to:
export default connect(() => ({}), () => ({}), null, { pure: false })(Routes);
it will work.
This is because connect() implements shouldComponentUpdate by default,
assuming that your component will produce the same results given the
same props and state.
route changes, but props don't so the view doesn't update.
You could achieve same with withRouter hoc.
Not meant to be a duplicate.
I fixed it with withRouter like this
import { withRouter } from 'react-router-dom';
and
export default withRouter( connect(mapStateToProps)(App) );
See Redux, Router integration docs here
Have you ever encountered the warning message:
Warning: You cannot change <Router history>
Well use withRouter from react-router-dom
I have searched for this for so long because the Redux was recreating my App.jsx component which has <Route> </Route> as parents and this warning just freezes the routing in my app. I wanted to have React/Redux component, because I needed to pass authenticated props to the Route component, and redirect base on it, simple.
So import { withRouter } from 'react-router-dom'
and surround your component which is connected to redux with:
export default withRouter(connect(mapStateToProps)(App));
Something more:
Most of the times if you want to communicate with the router, takes some props, pass something else to it, get history, locations form it and you are using Redux in your app, surround this component with withRouter and you will have access to these properties as props.
First things first is this possible to have 2 components on a page one displaying simple static markup but the second one in my parent is going to be a div that displays a link for each item in an array and if you click on it at the bottom of the div then data will be displayed for each one?
If this is possible are dynamic props as simple as performing .map inside the element and printing out a route?
Will also add that I am receiving the following on my Router object but I installed react-router globally though it is also in my node_modules folder.
'react-router' does not contain an export named 'hashHistory'.
import React, { Component } from 'react';
import { Router, Route, IndexRoute, hashHistory } from "react-router";
class DetailsComponent extends Component {
render() {
return (
<Router history={hashHistory}>
// in here will map this.props.data and for each one print a route
// the component for that route will be a DetailedViewComponent that
// that takes in the data in the props and renders it
// so i might need a link? in this render method aswell?
</Router>
);
}
}
export default DetailsComponent ;
React Router match params can be used to render content dynamically
ie. <Route path="/dynamicroute/:id" component={DynamicComponent}/> will provide an id param that can be retrieved via props.match.params inside <DynamicComponent/>
Spoke to some more senior react developers and they said what I was after was npm package Component-Router I haven't got back onto the project just yet but will post full code once completed :)
Wondering how to go back to a previous route in a react web app using hashRouter instead of browserRouter in react-router v4?
I've found this question which doesn't seem to work even though it says no browser mixin needed (plus I think its talking about an older react-router version) however, every other solution I've seen depends on browserHistory.
Is it possible with hashHistory?
this.props.history.goBack()
Taken from the comments on this question
It is a function call.
Well in my case i did like that :
import withRouter from "react-router-dom/es/withRouter";
import React from "react";
class Component extends React.Component {
goBack() {
this.props.history.go(-1);
}
...
}
const WrappedComponent = withRouter(Component)
export default WrappedComponent;
withRouter give us access to history in props of component, but i'm not sure is this way is correct
I wanted to build a Facebook login into my react/react-router/flux application.
I have a listener registered on the login event and would like to redirect the user to '/dashboard' if they are logged in. How can I do that? location.push didn't work very well, except after reloading the page completely.
React Router v3
This is what I do
var Router = require('react-router');
Router.browserHistory.push('/somepath');
React Router v4
Now we can use the <Redirect>component in React Router v4.
Rendering a <Redirect> will navigate to a new location. The new location will override the current location in the history stack, like server-side redirects.
import React, { Component } from 'react';
import { Redirect } from 'react-router';
export default class LoginComponent extends Component {
render(){
if(this.state.isLoggedIn === true){
return (<Redirect to="/your/redirect/page" />);
}else{
return (<div>Login Please</div>);
}
}
}
Documentation https://reacttraining.com/react-router/web/api/Redirect
React Router v0.13
The Router instance returned from Router.create can be passed around (or, if inside a React component, you can get it from the context object), and contains methods like transitionTo that you can use to transition to a new route.
React Router v2
Even though the question is already answered, I think it's relevant to post the solution that worked for me, since it wasn't covered in any of the solutions given here.
First, I'm using the router context on my LoginForm component
LoginForm.contextTypes = {
router: React.PropTypes.object
};
After that, I can access the router object inside my LoginForm component
handleLogin() {
this.context.router.push('/anotherroute');
}
PS: working on React-router version 2.6.0
React Router v3
Navigating Outside of Components
create your app with Router like this
// Your main file that renders a <Router>:
import { Router, browserHistory } from 'react-router'
import routes from './app/routes'
render(
<Router history={browserHistory} routes={routes} />,
mountNode
)
Somewhere like a Redux middleware or Flux action:
import { browserHistory } from 'react-router'
// Go to /some/path.
browserHistory.push('/some/path')
// Go back to previous location.
browserHistory.goBack()

React Router v4.2.0
I am using React-16.2.0 & React-router-4.2.0
And I get solution by this code
this.props.history.push("/");
My working code:
.then(response => response.json())
.then(data => {
if(data.status == 200){
this.props.history.push("/");
console.log('Successfully Login');
}
})
I was following this document redirect-on-login-and-logout
I was also try by return <Redirect to='/' /> But unlucky, this not working for me.
React router v5 using hooks
These steps are for authorisation redirect. But can be used for login/logout redirection also.
The <Redirect/> accepts to prop as a string or an object. We can utilise the object to pass the redirection path after login/logout using hooks easily.
Get the pathname of url from where the <Redirect/> is called using
useLocation()
const {pathname} = useLocation()
In the to prop of <Redirect/> pass in the following object:
<Redirect to={{pathname:'/login',state: {referrer: pathname}}/>
In the Login component access the route state variable using useLocation() hook and use the useHistory() hook to redirect after successful login.
const history = useHistory();
const location = useLocation();
const login() => {
// After login success
const {state: {referrer}} = location;
history.push(referrer)
};
Check the official docs here
React Router v3
Navigating inside components
You should use withRouter decorator when it's necessary to redirect inside a component. The decorator uses context instead of you.
import {withRouter} from 'react-router'
fucntion Foo(props) {
props.router.push('/users/16');
}
export default withRouter(Foo);
withRouter(Component, [options])
A HoC (higher-order component) that wraps another component to enhance
its props with router props.
withRouterProps = {
...componentProps,
router,
params,
location,
routes
}
Pass in your component and it will return the
wrapped component.
You can explicit specify router as a prop to the wrapper component to
override the router object from context.
In your store:
data.router.transitionTo('user');
And router has:
"Route name="user" handler={User}"
User is route handler
