I need some help to solve the following issue with using React.
In some web app I have a landing page, where I want to redirect the user to the login page in case she or he is not logged in.
I want to use the following landing page (taken from some tutorial I found on the net) in order to use it as a model for mine.
The problem is that this is a function component while my landing page is a class component. According to what I understand I guess I need to consider the code inside useEffect and (somewhat) transfer it to componentDidMount() in my class component. But I don't know how to do that. history.replace will not work in a class component (no Hooks in Classes). Any advice from a more React experienced user will be very welcome.
import React, { useEffect, useState } from "react";
import { useAuthState } from "react-firebase-hooks/auth";
import { useHistory } from "react-router";
import "./Dashboard.css";
import { auth, db, logout } from "./firebase";
....
function Dashboard() {
const [user, loading, error] = useAuthState(auth);
const [name, setName] = useState("");
const history = useHistory();
....
useEffect(() => { // Important part for my question !
if (loading) return;
if (!user) return history.replace("/");
....
}, [user, loading]);
return (
<div>
{/*...*/}
<button className="dashboard__btn" onClick={logout}>
Logout
</button>
</div>
);
}
export default Dashboard;
Here is what I tried on my Class Component:
class MyCompo extends React.Component {
constructor(props) {
super(props);
}
componentDidMount() {
console.log("--componentDidMount(MyCompo)--");
const { history } = this.props
history.push("/login");
}
.....
}
But I get the following error:
TypeError: history is undefined
componentDidMount
=============== Added information ===============
Below is the relevant part of the code I have been working on:
This part is what works:
<Route exact path="/" component={TopMenu}>
{true && <Redirect to="/login" />}
</Route>
What I tried in the Links Component did not work.
The code:
....
ReactDOM.render(
<Router>
<Switch>
<Route exact path="/" component={TopMenu}>
{true && <Redirect to="/login" />}
</Route>
<Route exact path="/login" component={Login} />
<Route exact path="/section1" component={Section1Page}/>
<Route exact path="/section2" component={Section2Page}/>
<Route exact path="/section3" component={Section3Page}/>
</Switch>
</Router>,
document.getElementById('root')
);
....
const TopMenu = () => {
return (
<div className='page_container'>
<Title/>
<Links path='/'/>
<button className="dashboard__btn" onClick={logout}>
Logout
</button>
</div>
)
};
class Links extends React.Component {
constructor(props) {
super(props);
}
componentDidMount() {
console.log("--componentDidMount(Links)--");
// This is some code I tried with no success.
const { history } = this.props
//history.push("/login");
}
componentDidUpdate(prevProps, prevState) {
console.log("--componentDidUpdate(Links)--");
}
render() {
return (
<div className='links_container'>
{(this.props.path != '/mng') &&
<React.StrictMode>
<Link to='/mng'>{mnMgrStr()}</Link><br/>
</React.StrictMode>}
{(this.props.path != '/other') &&
<React.StrictMode>
<Link to='/other'>{otherInpStr()}</Link><br/>
</React.StrictMode>}
.......
</div>
)
}
}
Following the example on the React Router docs you can use withRouter if your component isn't already receiving the route props, otherwise you can access history from the props.
class MyComponent extends React.Component {
...
componentDidMount() {
const { history } = this.props
// do whatever with history here
}
...
}
In react-router-dom version 5 there are a couple ways a class component can access the history object.
Rendered directly by a Route component via the component, or render or children function props so route props (i.e. history, location, and match) are passed.
component: <Route path="....." component={MyCompo} />
render: <Route path="....." render={routeProps => <MyCompo {...routeProps} />} />
Access the history object from the passed route props:
class MyCompo extends React.Component {
componentDidMount() {
const { history } = this.props;
history.push("/login");
}
...
}
Decorated by the withRouter Higher Order Component so the route props are injected.
import { withRouter } from 'react-router-dom';
class MyCompo extends React.Component {
componentDidMount() {
const { history } = this.props;
history.push("/login");
}
...
}
export default withRouter(MyCompo);
Well I hope by answering this question I can save lot of time of others. Don't need to panic it's not a major issue. I will explain step by step reason and solution.
First of all why this happening is
In react-router-dom **V6 (version 6) latest ** there is no history export or redirect.
There is navigate construct.
So to achieve in functional component there is useNavigate() hook.
Now coming to answer...
To redirect in class component using react-router-dom V6 we have to use component.
So now one has to follow the following steps:
Import navigate
import { Navigate } from "react-router-dom";
Use Navigate to redirect
So above I discussed syntax to do so now coming to your exact problem
You have to redirect user to login if he is not logged in
You can follow these steps:
create state to store status of user like logged in or not (inside constructor of class)
this.state = {
userLogged: false,
};
in your render method you have to add some condition like if user is not logged in take user to login page. see below..
render() {
const { userLogged } = this.state;
if (goToPay) {
return (
<Navigate to="/cart" state={selectedTiffin} props={selectedTiffin} />
);
}
}
That's it.
It can be confusing so I am giving full example so you can save your lot of time..
import React from "react";
import { Navigate } from "react-router-dom";
class Solve extends React.Component {
constructor(props) {
super(props);
this.state = {
userLogged: false,
};
}
// here you can write code to set the status of user like logged in or not
render() {
const { userLogged } = this.state;
if (userLogged ) {
return (
<Navigate to="/cart" />
);
}
return (
<>
Here you can return your original component that should be render when user is log in
</>
);
}
}
I hope this will help and work. Thank You
In the current version of React Router (v3) I can accept a server response and use browserHistory.push to go to the appropriate response page. However, this isn't available in v4, and I'm not sure what the appropriate way to handle this is.
In this example, using Redux, components/app-product-form.js calls this.props.addProduct(props) when a user submits the form. When the server returns a success, the user is taken to the Cart page.
// actions/index.js
export function addProduct(props) {
return dispatch =>
axios.post(`${ROOT_URL}/cart`, props, config)
.then(response => {
dispatch({ type: types.AUTH_USER });
localStorage.setItem('token', response.data.token);
browserHistory.push('/cart'); // no longer in React Router V4
});
}
How can I make a redirect to the Cart page from function for React Router v4?
You can use the history methods outside of your components. Try by the following way.
First, create a history object used the history package:
// src/history.js
import { createBrowserHistory } from 'history';
export default createBrowserHistory();
Then wrap it in <Router> (please note, you should use import { Router } instead of import { BrowserRouter as Router }):
// src/index.jsx
// ...
import { Router, Route, Link } from 'react-router-dom';
import history from './history';
ReactDOM.render(
<Provider store={store}>
<Router history={history}>
<div>
<ul>
<li><Link to="/">Home</Link></li>
<li><Link to="/login">Login</Link></li>
</ul>
<Route exact path="/" component={HomePage} />
<Route path="/login" component={LoginPage} />
</div>
</Router>
</Provider>,
document.getElementById('root'),
);
Change your current location from any place, for example:
// src/actions/userActionCreators.js
// ...
import history from '../history';
export function login(credentials) {
return function (dispatch) {
return loginRemotely(credentials)
.then((response) => {
// ...
history.push('/');
});
};
}
UPD: You can also see a slightly different example in React Router FAQ.
React Router v4 is fundamentally different from v3 (and earlier) and you cannot do browserHistory.push() like you used to.
This discussion seems related if you want more info:
Creating a new browserHistory won't work because <BrowserRouter> creates its own history instance, and listens for changes on that. So a different instance will change the url but not update the <BrowserRouter>.
browserHistory is not exposed by react-router in v4, only in v2.
Instead you have a few options to do this:
Use the withRouter high-order component
Instead you should use the withRouter high order component, and wrap that to the component that will push to history. For example:
import React from "react";
import { withRouter } from "react-router-dom";
class MyComponent extends React.Component {
...
myFunction() {
this.props.history.push("/some/Path");
}
...
}
export default withRouter(MyComponent);
Check out the official documentation for more info:
You can get access to the history object’s properties and the closest <Route>'s match via the withRouter higher-order component. withRouter will re-render its component every time the route changes with the same props as <Route> render props: { match, location, history }.
Use the context API
Using the context might be one of the easiest solutions, but being an experimental API it is unstable and unsupported. Use it only when everything else fails. Here's an example:
import React from "react";
import PropTypes from "prop-types";
class MyComponent extends React.Component {
static contextTypes = {
router: PropTypes.object
}
constructor(props, context) {
super(props, context);
}
...
myFunction() {
this.context.router.history.push("/some/Path");
}
...
}
Have a look at the official documentation on context:
If you want your application to be stable, don't use context. It is an experimental API and it is likely to break in future releases of React.
If you insist on using context despite these warnings, try to isolate your use of context to a small area and avoid using the context API directly when possible so that it's easier to upgrade when the API changes.
Now with react-router v5 you can use the useHistory hook like this:
import { useHistory } from "react-router-dom";
function HomeButton() {
let history = useHistory();
function handleClick() {
history.push("/home");
}
return (
<button type="button" onClick={handleClick}>
Go home
</button>
);
}

Simplest way in React Router 4 is to use
this.props.history.push('/new/url');
But to use this method, your existing component should have access to history object. We can get access by
If your component is linked to Route directly, then your component already has access to history object.
eg:
<Route path="/profile" component={ViewProfile}/>
Here ViewProfile has access to history.
If not connected to Route directly.
eg:
<Route path="/users" render={() => <ViewUsers/>}
Then we have to use withRouter, a heigher order fuction to warp the existing component.
Inside ViewUsers component
import { withRouter } from 'react-router-dom';
export default withRouter(ViewUsers);
That's it now, your ViewUsers component has access to history object.
UPDATE
2- in this scenario, pass all route props to your component, and then we can access this.props.history from the component even without a HOC
eg:
<Route path="/users" render={props => <ViewUsers {...props} />}
This is how I did it:
import React, {Component} from 'react';
export default class Link extends Component {
constructor(props) {
super(props);
this.onLogout = this.onLogout.bind(this);
}
onLogout() {
this.props.history.push('/');
}
render() {
return (
<div>
<h1>Your Links</h1>
<button onClick={this.onLogout}>Logout</button>
</div>
);
}
}
Use this.props.history.push('/cart'); to redirect to cart page it will be saved in history object.
Enjoy, Michael.
According to React Router v4 documentation - Redux Deep Integration session
Deep integration is needed to:
"be able to navigate by dispatching actions"
However, they recommend this approach as an alternative to the "deep integration":
"Rather than dispatching actions to navigate you can pass the history object provided to route components to your actions and navigate with it there."
So you can wrap your component with the withRouter high order component:
export default withRouter(connect(null, { actionCreatorName })(ReactComponent));
which will pass the history API to props. So you can call the action creator passing the history as a param. For example, inside your ReactComponent:
onClick={() => {
this.props.actionCreatorName(
this.props.history,
otherParams
);
}}
Then, inside your actions/index.js:
export function actionCreatorName(history, param) {
return dispatch => {
dispatch({
type: SOME_ACTION,
payload: param.data
});
history.push("/path");
};
}
Nasty question, took me quite a lot of time, but eventually, I solved it this way:
Wrap your container with withRouter and pass history to your action in mapDispatchToProps function. In action use history.push('/url') to navigate.
Action:
export function saveData(history, data) {
fetch.post('/save', data)
.then((response) => {
...
history.push('/url');
})
};
Container:
import { withRouter } from 'react-router-dom';
...
const mapDispatchToProps = (dispatch, ownProps) => {
return {
save: (data) => dispatch(saveData(ownProps.history, data))}
};
export default withRouter(connect(mapStateToProps, mapDispatchToProps)(Container));
This is valid for React Router v4.x.
I offer one more solution in case it is worthful for someone else.
I have a history.js file where I have the following:
import createHistory from 'history/createBrowserHistory'
const history = createHistory()
history.pushLater = (...args) => setImmediate(() => history.push(...args))
export default history
Next, on my Root where I define my router I use the following:
import history from '../history'
import { Provider } from 'react-redux'
import { Router, Route, Switch } from 'react-router-dom'
export default class Root extends React.Component {
render() {
return (
<Provider store={store}>
<Router history={history}>
<Switch>
...
</Switch>
</Router>
</Provider>
)
}
}
Finally, on my actions.js I import History and make use of pushLater
import history from './history'
export const login = createAction(
...
history.pushLater({ pathname: PATH_REDIRECT_LOGIN })
...)
This way, I can push to new actions after API calls.
Hope it helps!
this.context.history.push will not work.
I managed to get push working like this:
static contextTypes = {
router: PropTypes.object
}
handleSubmit(e) {
e.preventDefault();
if (this.props.auth.success) {
this.context.router.history.push("/some/Path")
}
}
Be careful that don't use react-router#5.2.0 or react-router-dom#5.2.0 with history#5.0.0. URL will update after history.push or any other push to history instructions but navigation is not working with react-router. use npm install history#4.10.1 to change the history version. see React router not working after upgrading to v 5.
I think this problem is happening when push to history happened. for example using <NavLink to="/apps"> facing a problem in NavLink.js that consume <RouterContext.Consumer>. context.location is changing to an object with action and location properties when the push to history occurs. So currentLocation.pathname is null to match the path.
In this case you're passing props to your thunk. So you can simply call
props.history.push('/cart')
If this isn't the case you can still pass history from your component
export function addProduct(data, history) {
return dispatch => {
axios.post('/url', data).then((response) => {
dispatch({ type: types.AUTH_USER })
history.push('/cart')
})
}
}
I struggled with the same topic.
I'm using react-router-dom 5, Redux 4 and BrowserRouter.
I prefer function based components and hooks.
You define your component like this
import { useHistory } from "react-router-dom";
import { useDispatch } from "react-redux";
const Component = () => {
...
const history = useHistory();
dispatch(myActionCreator(otherValues, history));
};
And your action creator is following
const myActionCreator = (otherValues, history) => async (dispatch) => {
...
history.push("/path");
}
You can of course have simpler action creator if async is not needed
Here's my hack (this is my root-level file, with a little redux mixed in there - though I'm not using react-router-redux):
const store = configureStore()
const customHistory = createBrowserHistory({
basename: config.urlBasename || ''
})
ReactDOM.render(
<Provider store={store}>
<Router history={customHistory}>
<Route component={({history}) => {
window.appHistory = history
return (
<App />
)
}}/>
</Router>
</Provider>,
document.getElementById('root')
)
I can then use window.appHistory.push() anywhere I want (for example, in my redux store functions/thunks/sagas, etc) I had hoped I could just use window.customHistory.push() but for some reason react-router never seemed to update even though the url changed. But this way I have the EXACT instance react-router uses. I don't love putting stuff in the global scope, and this is one of the few things I'd do that with. But it's better than any other alternative I've seen IMO.
If you are using Redux, then I would recommend using npm package react-router-redux. It allows you to dispatch Redux store navigation actions.
You have to create store as described in their Readme file.
The easiest use case:
import { push } from 'react-router-redux'
this.props.dispatch(push('/second page'));
Second use case with Container/Component:
Container:
import { connect } from 'react-redux';
import { push } from 'react-router-redux';
import Form from '../components/Form';
const mapDispatchToProps = dispatch => ({
changeUrl: url => dispatch(push(url)),
});
export default connect(null, mapDispatchToProps)(Form);
Component:
import React, { Component } from 'react';
import PropTypes from 'prop-types';
export default class Form extends Component {
handleClick = () => {
this.props.changeUrl('/secondPage');
};
render() {
return (
<div>
<button onClick={this.handleClick}/>
</div>Readme file
);
}
}
I was able to accomplish this by using bind(). I wanted to click a button in index.jsx, post some data to the server, evaluate the response, and redirect to success.jsx. Here's how I worked that out...
index.jsx:
import React, { Component } from "react"
import { postData } from "../../scripts/request"
class Main extends Component {
constructor(props) {
super(props)
this.handleClick = this.handleClick.bind(this)
this.postData = postData.bind(this)
}
handleClick() {
const data = {
"first_name": "Test",
"last_name": "Guy",
"email": "test#test.com"
}
this.postData("person", data)
}
render() {
return (
<div className="Main">
<button onClick={this.handleClick}>Test Post</button>
</div>
)
}
}
export default Main
request.js:
import { post } from "./fetch"
export const postData = function(url, data) {
// post is a fetch() in another script...
post(url, data)
.then((result) => {
if (result.status === "ok") {
this.props.history.push("/success")
}
})
}
success.jsx:
import React from "react"
const Success = () => {
return (
<div className="Success">
Hey cool, got it.
</div>
)
}
export default Success
So by binding this to postData in index.jsx, I was able to access this.props.history in request.js... then I can reuse this function in different components, just have to make sure I remember to include this.postData = postData.bind(this) in the constructor().
so the way I do it is:
- instead of redirecting using history.push, I just use Redirect component from react-router-dom
When using this component you can just pass push=true, and it will take care of the rest
import * as React from 'react';
import { Redirect } from 'react-router-dom';
class Example extends React.Component {
componentDidMount() {
this.setState({
redirectTo: '/test/path'
});
}
render() {
const { redirectTo } = this.state;
return <Redirect to={{pathname: redirectTo}} push={true}/>
}
}
Use Callback. It worked for me!
export function addProduct(props, callback) {
return dispatch =>
axios.post(`${ROOT_URL}/cart`, props, config)
.then(response => {
dispatch({ type: types.AUTH_USER });
localStorage.setItem('token', response.data.token);
callback();
});
}
In component, you just have to add the callback
this.props.addProduct(props, () => this.props.history.push('/cart'))
React router V4 now allows the history prop to be used as below:
this.props.history.push("/dummy",value)
The value then can be accessed wherever the location prop is available as
state:{value} not component state.
As we have a history already included in react router 5, we can access the same with reference
import React from 'react';
import { BrowserRouter, Switch, Route } from 'react-router-dom';
function App() {
const routerRef = React.useRef();
const onProductNav = () => {
const history = routerRef.current.history;
history.push("product");
}
return (
<BrowserRouter ref={routerRef}>
<Switch>
<Route path="/product">
<ProductComponent />
</Route>
<Route path="/">
<HomeComponent />
</Route>
</Switch>
</BrowserRouter>
)
}
step one wrap your app in Router
import { BrowserRouter as Router } from "react-router-dom";
ReactDOM.render(<Router><App /></Router>, document.getElementById('root'));
Now my entire App will have access to BrowserRouter. Step two I import Route and then pass down those props. Probably in one of your main files.
import { Route } from "react-router-dom";
//lots of code here
//somewhere in my render function
<Route
exact
path="/" //put what your file path is here
render={props => (
<div>
<NameOfComponent
{...props} //this will pass down your match, history, location objects
/>
</div>
)}
/>
Now if I run console.log(this.props) in my component js file that I should get something that looks like this
{match: {…}, location: {…}, history: {…}, //other stuff }
Step 2 I can access the history object to change my location
//lots of code here relating to my whatever request I just ran delete, put so on
this.props.history.push("/") // then put in whatever url you want to go to
Also I'm just a coding bootcamp student, so I'm no expert, but I know you can also you use
window.location = "/" //wherever you want to go
Correct me if I'm wrong, but when I tested that out it reloaded the entire page which I thought defeated the entire point of using React.
Create a custom Router with its own browserHistory:
import React from 'react';
import { Router } from 'react-router-dom';
import { createBrowserHistory } from 'history';
export const history = createBrowserHistory();
const ExtBrowserRouter = ({children}) => (
<Router history={history} >
{ children }
</Router>
);
export default ExtBrowserRouter
Next, on your Root where you define your Router, use the following:
import React from 'react';
import { /*BrowserRouter,*/ Route, Switch, Redirect } from 'react-router-dom';
//Use 'ExtBrowserRouter' instead of 'BrowserRouter'
import ExtBrowserRouter from './ExtBrowserRouter';
...
export default class Root extends React.Component {
render() {
return (
<Provider store={store}>
<ExtBrowserRouter>
<Switch>
...
<Route path="/login" component={Login} />
...
</Switch>
</ExtBrowserRouter>
</Provider>
)
}
}
Finally, import history where you need it and use it:
import { history } from '../routers/ExtBrowserRouter';
...
export function logout(){
clearTokens();
history.push('/login'); //WORKS AS EXPECTED!
return Promise.reject('Refresh token has expired');
}
you can use it like this as i do it for login and manny different things
class Login extends Component {
constructor(props){
super(props);
this.login=this.login.bind(this)
}
login(){
this.props.history.push('/dashboard');
}
render() {
return (
<div>
<button onClick={this.login}>login</login>
</div>
)
/*Step 1*/
myFunction(){ this.props.history.push("/home"); }
/**/
<button onClick={()=>this.myFunction()} className={'btn btn-primary'}>Go
Home</button>
If you want to use history while passing a function as a value to a Component's prop, with react-router 4 you can simply destructure the history prop in the render attribute of the <Route/> Component and then use history.push()
<Route path='/create' render={({history}) => (
<YourComponent
YourProp={() => {
this.YourClassMethod()
history.push('/')
}}>
</YourComponent>
)} />
Note: For this to work you should wrap React Router's BrowserRouter Component around your root component (eg. which might be in index.js)
I know there are quite a few questions on this, but I cannot seem to get it to work: I need to access "history" from the child components that are rendered through the Routes. (It receives props from a redux container).
I need to pass down the history object to the components that are rendered in each Route, so that I can this.props.history.push('/route') in the child components. This application was less dynamic before, so each Route was hardcoded with a component={someComponent}; but I found that in doing the Routes dynamically, you need to use render={() => <someComponent />}.
After changing the Routes from component={} to render={() => ...} I lost history in the child components.
My code is something like:
import React, {Component} from 'react';
import ReactDOM from 'react-dom';
import { HashRouter as Router, Link, Route, Redirect } from 'react-router-dom';
import { Nav_Item } from '.'
import DynamicTab from '.';
export default class NavBar extends React.Component {
constructor(props) {
super(props);
this.state={}
}
render() {
let tabs = [];
let routes = [];
this.props.tabs.forEach( function(tab, index) {
tabs.push(<Nav_Item key={tab.name} path_name={'/' + tab.name} tab_text={tab.label} />);
routes.push(<Route key={tab.name} path={'/' + tab.name} render={() => <DynamicTab tabName={tab.name} tabSpecs={tab} />} />);
})
return (
<Router>
<div>
<div>
<ol>
{ tabs }
</ol>
</div>
<Redirect to={'/' + this.props.tabs[0].name} />
{ routes }
</div>
</Router>
)
}
}
When you use render you actually get props. In the docs they have an example like this:
<Route {...rest} render={props => (
<FadeIn>
<Component {...props}/>
</FadeIn>
)}/>
So you should be able to access history from those props.
Another solution would be to conditionally render a <Redirect/> component. So maybe you have some internal state that you use like this:
// in your components render function..
if(this.state.shouldRedirect) {
return (<Redirect to={yourURL} />);
}
this.props.router and you have access to whatever you want.
in your case you can just do:
this.props.router.push("/newurl");
There is no need to pass the history as a separate property if this component is rendered by the router.
I am developing an application in which I check if the user is not loggedIn. I have to display the login form, else dispatch an action that would change the route and load other component. Here is my code:
render() {
if (isLoggedIn) {
// dispatch an action to change the route
}
// return login component
<Login />
}
How can I achieve this as I cannot change states inside the render function.
Considering you are using react-router v4
Use your component with withRouter and use history.push from props to change the route. You need to make use of withRouter only when your component is not receiving the Router props, this may happen in cases when your component is a nested child of a component rendered by the Router and you haven't passed the Router props to it or when the component is not linked to the Router at all and is rendered as a separate component from the Routes.
import {withRouter} from 'react-router';
class App extends React.Component {
...
componenDidMount() {
// get isLoggedIn from localStorage or API call
if (isLoggedIn) {
// dispatch an action to change the route
this.props.history.push('/home');
}
}
render() {
// return login component
return <Login />
}
}
export default withRouter(App);
Important Note
If you are using withRouter to prevent updates from being blocked by
shouldComponentUpdate, it is important that withRouter wraps the
component that implements shouldComponentUpdate. For example, when
using Redux:
// This gets around shouldComponentUpdate
withRouter(connect(...)(MyComponent))
// This does not
connect(...)(withRouter(MyComponent))
or you could use Redirect
import {withRouter} from 'react-router';
class App extends React.Component {
...
render() {
if(isLoggedIn) {
return <Redirect to="/home"/>
}
// return login component
return <Login />
}
}
With react-router v2 or react-router v3, you can make use of context to dynamically change the route like
class App extends React.Component {
...
render() {
if (isLoggedIn) {
// dispatch an action to change the route
this.context.router.push('/home');
}
// return login component
return <Login />
}
}
App.contextTypes = {
router: React.PropTypes.object.isRequired
}
export default App;
or use
import { browserHistory } from 'react-router';
browserHistory.push('/some/path');
In react-router version 4:
import React from 'react'
import { BrowserRouter as Router, Route, Redirect} from 'react-router-dom'
const Example = () => (
if (isLoggedIn) {
<OtherComponent />
} else {
<Router>
<Redirect push to="/login" />
<Route path="/login" component={Login}/>
</Router>
}
)
const Login = () => (
<h1>Form Components</h1>
...
)
export default Example;
Another alternative is to handle this using Thunk-style asynchronous actions (which are safe/allowed to have side-effects).
If you use Thunk, you can inject the same history object into both your <Router> component and Thunk actions using thunk.withExtraArgument, like this:
import React from 'react'
import { BrowserRouter as Router, Route, Redirect} from 'react-router-dom'
import { createBrowserHistory } from "history"
import { applyMiddleware, createStore } from "redux"
import thunk from "redux-thunk"
const history = createBrowserHistory()
const middlewares = applyMiddleware(thunk.withExtraArgument({history}))
const store = createStore(appReducer, middlewares)
render(
<Provider store={store}
<Router history={history}>
<Route path="*" component={CatchAll} />
</Router
</Provider>,
appDiv)
Then in your action-creators, you will have a history instance that is safe to use with ReactRouter, so you can just trigger a regular Redux event if you're not logged in:
// meanwhile... in action-creators.js
export const notLoggedIn = () => {
return (dispatch, getState, {history}) => {
history.push(`/login`)
}
}
Another advantage of this is that the url is easier to handle, now, so we can put redirect info on the query string, etc.
You can try still doing this check in your Render methods, but if it causes problems, you might consider doing it in componentDidMount, or elsewhere in the lifecycle (although also I understand the desire to stick with Stateless Functional Compeonents!)
You can still use Redux and mapDispatchToProps to inject the action creator into your comptonent, so your component is still only loosely connected to Redux.
This is my handle loggedIn. react-router v4
PrivateRoute is allow enter path if user is loggedIn and save the token to localStorge
function PrivateRoute({ component: Component, ...rest }) {
return (
<Route
{...rest}
render={props => (localStorage.token) ? <Component {...props} /> : (
<Redirect
to={{
pathname: '/signin',
state: { from: props.location },
}}
/>
)
}
/>
);
}
Define all paths in your app in here
export default (
<main>
<Switch>
<Route exact path="/signin" component={SignIn} />
<Route exact path="/signup" component={SignUp} />
<PrivateRoute path="/" component={Home} />
</Switch>
</main>
);
Those who are facing issues in implementing this on react-router v4. Here is a working solution for navigating through the react app programmatically.
history.js
import createHistory from 'history/createBrowserHistory'
export default createHistory()
App.js OR Route.jsx. Pass history as a prop to your Router.
import { Router, Route } from 'react-router-dom'
import history from './history'
...
<Router history={history}>
<Route path="/test" component={Test}/>
</Router>
You can use push() to navigate.
import history from './history'
...
render() {
if (isLoggedIn) {
history.push('/test') // this should change the url and re-render Test component
}
// return login component
<Login />
}
All thanks to this comment: https://github.com/ReactTraining/react-router/issues/3498#issuecomment-301057248
render(){
return (
<div>
{ this.props.redirect ? <Redirect to="/" /> :'' }
<div>
add here component codes
</div>
</div>
);
}
I would suggest you to use connected-react-router https://github.com/supasate/connected-react-router
which helps to perform navigation even from reducers/actions if you want.
it is well documented and easy to configure
I was able to use history within stateless functional component, using withRouter following way (needed to ignore typescript warning):
import { withRouter } from 'react-router-dom';
...
type Props = { myProp: boolean };
// #ts-ignore
export const MyComponent: FC<Props> = withRouter(({ myProp, history }) => {
...
})
import { useNavigate } from "react-router-dom"; //with v6
export default function Component() {
const navigate = useNavigate();
navigate.push('/path');
}
I had this issue and just solved it with the new useNavigate hook in version 6 of react-router-dom
I need to navigate to a route after an event is successful.
This seems to have changed since previous versions.
Previously we would do this:
import { browserHistory } from 'react-router';
...
handleClick(){
doSomething();
browserHistory.push('/some/path');
}
This example works in react-router and react-router-dom v4.0.0.
We have 3 components:
App.js - holds both Component 1 and Component 2
Component1.js - not wrapped in a Route and will always be rendered, but this will not have a reference of the "route props" - (history, location, match...)
Component2.js - rendered only if the route location match. Important thing to note that this component will be rendered with "route props"
To navigate programmatically, you can use react-router history object.
this.props.history.push('path');
This will work right off the bat for components rendered via Route, as these components will already have access to the route props (history). In our example this is Component2. However, for components that are not rendered via a Route (e.g. Component1), you would need to wrap it in withRouter to give you access to the history object.
App.js
import React, { Component } from 'react';
import { BrowserRouter, Route } from 'react-router-dom';
import Component1 from './Component1';
import Component2 from './Component2';
class App extends Component {
render() {
return (
<BrowserRouter>
<div>
<Component1 />
<Route path="/render1" render={() => <div>Rendered from Component1</div>} />
<Route path="/" component={Component2} />
<Route path="/render2" render={() => <div>Rendered from Component2</div>} />
</div>
</BrowserRouter>
)
}
}
export default App;
Component1.js
import React from 'react';
import { withRouter } from 'react-router';
class Component1 extends React.Component {
handleButtonClick() {
this.props.history.push('/render1');
}
render() {
return (
<div>
<h1>Component 1</h1>
<button onClick={this.handleButtonClick.bind(this)}>Component 1 Button</button>
</div>
);
}
}
const Component1WithRouter = withRouter(Component1);
export default Component1WithRouter;
For Component1, we wrapped it in withRouter, and then exported the returned wrapped object. Some gotcha, notice that in App.js, we still reference it as Component1 instead of Component1WithRouter
Component2.js
import React from 'react';
class Component2 extends React.Component {
handleButtonClick() {
this.props.history.push('/render2');
}
render() {
return (
<div>
<h1>Component 2</h1>
<button onClick={this.handleButtonClick.bind(this)}>Component 2 Button</button>
</div>
);
}
}
export default Component2;
For Component2, the history object is already available from this.props. You just need to invoke the push function.
If you are using "function components" and Hooks, instead of expecting props, use the useHistory() function instead:
import {useHistory} from 'react-router-dom';
export default function MyFunctionComponent() {
const history = useHistory();
const myEventHandler = () => {
// do stuff
history.push('/newpage');
};
// ...
}
Just render a redirect component:
import { Redirect } from 'react-router';
// ...
<Redirect to="/some/path" />
See docs here: https://reacttraining.com/react-router/core/api/Redirect
I really appreciate CodinCat's answer since he helped me resolve a different error, but I found a more correct solution:
In React Router 4.0 (I don't know about previous versions) the router passes a history object to the component (i.e.: this.props.history). You can push your url onto that array to redirect:
this.props.history.push('/dogs');
In my case though, I had two levels of components, the router called a component called LoginPage, and LoginPage called a component called Login. You'll only have the history object in the props of your child object if you pass it on:
<Router>
<Route path="/dogs" component={DogsPage}/>
<Route path="/login" component={LoginPage}/>
</Router>
const LoginPage = (props) => {
// Here I have access to props.history
return (
<div>
<Login history={props.history} />
</div>
)
}
const Login = (props) => {
function handleClick(){
// Now we can simply push our url onto the history and the browser will update
props.history.push('/dogs');
}
return (
<div>
<button onClick={handleClick}>Click to Navigate</button>
</div>
)
}
I know the example above is a bit contrived, since it would be easier in this case to just use a link, but I made the example this way to keep it concise. There are many reasons you may need to navigate this way. In my case, I was doing a graphQL request and wanted to navigate to the home page once a person had successfully logged in.
