How to use react-router-dom v6 navigate in class component

I installed react-router-dom v6 and I want to use a class based component, in previous version of react-router-dom v5 this.props.history() worked for redirect page after doing something but this code not working for v6 .
In react-router-dom v6 there is a hook useNavigate for functional component but I need to use it in class base component , Please help me how to use navigate in class component ?

In the react-router-dom v6, the support for history has been deprecated but instead of it, navigate has been introduced. If you want to redirect user to a specific page on success of a specific event, then follow the steps given below:
Create a file named as withRouter.js, and paste the code given below in this file:
import { useNavigate } from 'react-router-dom';
export const withRouter = (Component) => {
const Wrapper = (props) => {
const navigate = useNavigate();
return (
<Component
navigate={navigate}
{...props}
/>
);
};
return Wrapper;
};
Now, in whichever class based component you want to redirect the user to a specific path/component, import the above withRouter.js file there and use this.props.navigate('/your_path_here') function for the redirection.
For your help, a sample code showing the same has been given below:
import React from 'react';
import {withRouter} from '.your_Path_To_Withrouter_Here/withRouter';
class Your_Component_Name_Here extends React.Component{
constructor(){
super()
this.yourFunctionHere=this.yourFunctionHere.bind(this);
}
yourFunctionHere()
{
this.props.navigate('/your_path_here')
}
render()
{
return(
<div>
Your Component Code Here
</div>
)
}
}
export default withRouter(Your_Component_Name_Here);
Above Code works Perfect. And this is just a small extension.
If you want onclick function here is the code:
<div className = "row">
<button className= "btn btn-primary"
onClick={this.yourFunctionHere}>RedirectTo</button>
</div>

in class base component for redirect user follow this step :
first import some component like this
import { Navigate } from "react-router-dom"
now make a state for Return a boolean value like this:
state = {
redirect:false
}
now insert Naviagate component to bottom of your component tree
but use && for conditional rendring like this :
{
this.state.redirect && <Navigate to='/some_route' replace={true}/>
}
now when you want redirect user to some page just make true redirect state
on a line of code you want
now you can see you navigate to some page :)

Try this:
import {
useLocation,
useNavigate,
useParams
} from "react-router-dom";
export const withRouter = (Component) => {
function ComponentWithRouterProp(props) {
let location = useLocation();
let navigate = useNavigate();
let params = useParams();
return (
<Component
{...props}
router={{ location, navigate, params }}
/>
);
}
return ComponentWithRouterProp;
}
and just used this function, in my case:
import { withRouter } from '../utils/with-router';
import './menu-item.styles.scss';
const MenuItem = ({title, imageUrl, size, linkUrl,router}) =>(
<div
className={`${size} menu-item`} onClick={() => router.navigate(`${router.location.pathname}${linkUrl}`)}
>
<div className='background-image'
style={{
backgroundImage: `url(${imageUrl})`
}} />
<div className="content">
<h1 className="title">{title.toUpperCase()}</h1>
<span className="subtitle">SHOP NOW</span>
</div>
</div>
)
export default withRouter(MenuItem);
I found this solution here https://www.reactfix.com/2022/02/fixed-how-can-i-use-withrouter-in-react.html
Other solution is useNavigate, for example:
<button onClick={() => {navigate("/dashboard");}} >
Dashboard
</button>

In a react class component use <Navigate>. From the react router docs:
A <Navigate> element changes the current location when it is rendered. It's a component wrapper around useNavigate, and accepts all the same arguments as props.

Try creating a reusable functional Component like a simple button and you can use it in your class component.
import React from "react";
import { useNavigate } from "react-router-dom";
const NavigateButton = ( { buttonTitle, route,isReplaced}) => {
const navigate = useNavigate();
return (
<button
className = "btn btn-primary"
onClick = { () => {
navigate( route , {replace:isReplaced} )
}}
>
{buttonTitle}
</button>;
);
});
export default NavigateButton;
After this, you can use NavigateButton in any of your class Components. And it will work.
<NavigateButton title = {"Route To"} route = {"/your_route/"} isReplaced = {false}/>

Found this explanation from the GitHub react-router issue thread, this explained how to use react-router 6 with class components
https://github.com/remix-run/react-router/issues/8146
I got this code from the above issue explanation
import React,{ Component} from "react";
import { useNavigate } from "react-router-dom";
export const withNavigation = (Component : Component) => {
return props => <Component {...props} navigate={useNavigate()} />;
}
//classComponent
class LoginPage extends React.Component{
submitHandler =(e) =>{
//successful login
this.props.navigate('/dashboard');
}
}
export default withNavigation(LoginPage);

If you need to use params for data fetching, writing a logic in your ClassComponent and render component depending on them, then create wrapper for your ClassComponentContainer
import { useLocation, useParams } from 'react-router-dom';
import ClassComponentContainer from './ClassComponentContainer';
export default function ClassComponentWrap(props) {
const location = useLocation();
const params = useParams();
return <ClassComponentContainer location={location} params={params} />
}
after it just use params in ClassComponent which is in props
import React from 'react';
import { connect } from 'react-redux';
import axios from 'axios';
import PresentationComponent from './PresentationComponent';
class ClassComponent extends React.Component {
componentDidMount() {
let postID = this.props.params.postID;
axios.get(`https://jsonplaceholder.typicode.com/posts/${postID}`)
.then((response) => {console.log(response)})
}
render() {
return <PresentationComponent {...this.props} />
}
}
const mapStateToProps = (state) => {...}
const mapDispatchToProps = (dispatch) => {...}
const ClassComponentContainer = connect(mapStateToProps, mapDispatchToProps)(ClassComponent);
export default ClassComponentContainer;
and use ClassComponentWrap component in Route element attribute
import { BrowserRouter, Route, Routes } from "react-router-dom";
import ClassComponentWrap from './components/ClassComponentWrap';
export default function App(props) {
return (
<BrowserRouter>
<Routes>
<Route path="/posts/:postID?" element={<ClassComponentWrap />} />
</Routes>
</BrowserRouter>
);
}

Here is my solution:
import React, { Component } from "react";
import { useNavigate } from "react-router-dom";
class OrdersView extends Component {
Test(props){
const navigate = useNavigate();
return(<div onClick={()=>{navigate('/')}}>test{props.test}</div>);
}
render() {
return (<div className="">
<this.Test test={'click me'}></this.Test>
</div>);
}
}

Context empty after async initialisation

I am trying to fetch data from a backend API and initialise my FieldsContext. I am unable to do it, it returns an empty fields array in the Subfields component. I have spent hours on fixing it. But I eventually give up. Please take a look into this. Thanks in advance.
Here is my code
App.js
import React from 'react';
import 'bootstrap/dist/css/bootstrap.min.css'
import './App.css';
import Index from './components/pages/index/'
import FieldsProvider from './providers/fieldProvider'
import AuthProvider from './providers/authProvider'
import {BrowserRouter as Router,Switch,Route} from 'react-router-dom';
import SubFields from './components/pages/subfields';
function App() {
return (
<Router>
<AuthProvider>
<FieldsProvider>
<Switch>
<Route exact path="/" component={Index} />
<Route exact path="/:fieldid/subfields" component={SubFields} />
</Switch>
</FieldsProvider>
</AuthProvider>
</Router>
);
}
export default App;
FieldsContext.js
import React from 'react'
const FieldsContext = React.createContext();
export default FieldsContext
FieldsProvider.js
import React, { Component } from 'react'
import FieldsContext from '../libs/fieldContext'
export default class FieldsProvider extends Component {
state = {fields:[]}
getFields()
{
fetch('/api/fields')
.then(res => res.json())
.then(fields => this.setState({fields}));
}
async componentDidMount() {
await this.getFields();
}
render() {
return (
<FieldsContext.Provider value={this.state} >
{this.props.children}
</FieldsContext.Provider>
)
}
}
Subfields.js
import React, { Component } from 'react'
import FieldsContext from '../../../libs/fieldContext'
import FieldsList from '../../Fields/fieldlist'
export default class SubFields extends Component {
componentDidMount(){
// const fieldId = this.props.match.params.fieldid;
console.log(this.context);
}
render() {
return (
<div>
</div>
)
}
}
SubFields.contextType = FieldsContext

try using an ES6 Arrow function, which binds the function to the object instance, so that this refers to the object instance of the class when it is called.
When its called asynchronously, this will refer the the class object instance you want to update.
import React, { Component } from 'react'
import FieldsContext from '../libs/fieldContext'
export default class FieldsProvider extends Component {
state = {fields:[]}
// ES6 Arrow function
getFields = () =>
{
fetch('/api/fields')
.then(res => res.json())
.then(fields => this.setState({fields}));
}
async componentDidMount() {
await this.getFields();
}
render() {
return (
<FieldsContext.Provider value={this.state} >
{this.props.children}
</FieldsContext.Provider>
)
}
}
Alternatively, Try binding of your function in the class constructor.
export default class FieldsProvider extends Component {
state = {fields:[]}
constructor(props) {
//bind the class function to this instance
this.getFields = this.getFields.bind(this);
}
//Class function
getFields()
{
fetch('/api/fields')
.then(res => res.json())
.then(fields => this.setState({fields}));
}
async componentDidMount() {
await this.getFields();
}
render() {
return (
<FieldsContext.Provider value={this.state} >
{this.props.children}
</FieldsContext.Provider>
)
}
}
As a side note: Prefer to use functional components for consuming of ContextAPI.
import React, { Component } from 'react'
import FieldsContext from '../../../libs/fieldContext'
import FieldsList from '../../Fields/fieldlist'
export default function SubFields (props) {
const {
match
} = props;
//much better way to consume mulitple Contexts
const { fields } = React.useContext(FieldsContext);
//useEffect with fields dependency
React.useEffect(() => {
console.log(fields);
},[fields]);
return (
<div>
</div>
)
}

Update state for component by event handle in other component in different file?

I have two component in my project one is Tag and the other is LandingTicker so i want when i click Tag componet update state for LandTicker componet, and landticker componet in different file.
how i can do that?
thank you.
Tag component code::
tag/index.js
import React from 'react';
import './index.scss';
class Tag extends React.Component {
handleClick(e) {
let tags = document.querySelectorAll('.show-clickable');
Array.from(tags).map(el => el.classList.remove('selected-tag'))
e.target.classList.add('selected-tag');
/*
Here i should update the state for LandingTicker component.
and remember any component in different file.
How i can do that???
*/
}
render() {
return (
<div
className="show-clickable"
onClick={this.handleClick}
>
click here
</div>
);
}
}
export default Tag;
LandingTicker component code::
LandingTicker/index.js
import React from 'react';
import TickerRow from './TickerRow';
import './index.scss';
class LandingTicker extends React.Component {
state = {
coin: 'USD'
}
render() {
return (
<div className="landing-ticker__body">
{selectCoin(this.state.coin)}
</div>
</div>
);
}
}
const selectCoin = (coin) => {
const coins = {
USD: ['BTCUSD', 'ETHUSD', 'EOSUSD', 'LTCUSD'],
EUR: ['BTCEUR', 'ETHEUR', 'EOSEUR'],
GBP: ['BTCGBP', 'EOSGBP'],
JPY: ['BTCJPY', 'ETHJPY'],
};
return (
coins[coin].map(el =>
<TickerRow symbol={el} key={el.toString()} />
)
);
}
export default LandingTicker;
Edit:
my component Hierarchy::
StatusTable
TagsTable
Tag
TickerSearch
LandingTickers
TickersRow
StatusTable component code::
import React from 'react';
import TagsTable from './TagsTable';
import TickerSearch from './TickerSearch';
import LandingTicker from './LandingTicker';
import './StatusTable.scss';
class StatusTable extends React.Component {
render() {
return (
<div className="status-table">
<TagsTable />
<TickerSearch />
<LandingTicker />
</div>
);
}
}
export default StatusTable;

React handle all its component data in the form of state and props(immutable). So it is easy to pass data from parent to child or one component to another using props :
Your Tag.js file:
import React, { Component } from "react";
import LandingTicker from "./LandTicker";
class Tag extends Component {
constructor(props) {
super(props);
this.state = {
trigger: true
};
}
handleClick(e) {
// do all logic here and set state here
this.setState({ trigger: this.state.trigger });
}
render() {
//And then pass this state here as a props
return (
<div className="show-clickable" onClick={this.handleClick}>
click here
<LandingTicker trigger={this.state.trigger} />
</div>
);
}
}
export default Tag;
Inside LandTicker.js file:
import React from 'react';
import TickerRow from './TickerRow';
import './index.scss';
class LandingTicker extends React.Component {
state = {
coin: 'USD'
}
render() {
//Catch your props from parent here
//i.e this.props(it contains all data you sent from parent)
return (
<div className="landing-ticker__body">
{selectCoin(this.state.coin)}
</div>
);
}
}
const selectCoin = (coin) => {
const coins = {
USD: ['BTCUSD', 'ETHUSD', 'EOSUSD', 'LTCUSD'],
EUR: ['BTCEUR', 'ETHEUR', 'EOSEUR'],
GBP: ['BTCGBP', 'EOSGBP'],
JPY: ['BTCJPY', 'ETHJPY'],
};
return (
coins[coin].map(el =>
<TickerRow symbol={el} key={el.toString()} />
)
);
}
export default LandingTicker;

I think this is the best answer for your question if you don't use state management system such as Redux or Mobx.

(you need to check third option)

Material-UI component variants are not being applied

I'm using material-ui in a react app. Here's the code in question (I'll include the redux stuff just in case):
import React from 'react';
import { connect } from 'react-redux';
import { Button } from '#material-ui/core';
class App extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<Button variant="contained" href="#constrained-buttons">
Link
</Button>
</div>
);
}
}
function mapStateToProps(state) {
const { alert } = state;
return {
alert
};
}
const connectedApp = connect(mapStateToProps)(App);
export { connectedApp as App };
I'm using https://material-ui.com/demos/buttons/ as a guide. Here's what shows up:
This is all that shows up. Any thoughts?

React: Render other blocks

I'm new to reactjs, I'm trying to communicate 2 component and render again one of them.
I have the following:
layout.js
import React from 'react';
...
class Layout extends React.Component {
constructor(props) {
super(props);
this.state = {
toolbar: 'none'
};
}
getChildContext() {
let me = this;
return {
changeToolbar: function (newToolbar) {
me.setState({ toolbar: newToolbar })
}
}
}
render() {
const {Search, Nav} = this.props;
return (
<div className="wrap">
<Header Search={Search} />
<Toolbar toolbar={this.state.toolbar} />
<div className="main">
<Nav />
<div className="content">
{this.props.children}
</div>
</div>
</div>
)
}
}
Layout.childContextTypes = {
changeToolbar: React.PropTypes.func
}
export default Layout;
toolbar.js
import React from 'react';
...
import ProductToolbar from '../components/toolbar/productToolbar';
import SalesToolbar from '../components/toolbar/salesToolbar';
class Toolbar extends React.Component {
static propTypes = {
toolbar: React.PropTypes.string.isRequired
};
state = {
toolbar: this.props.toolbar
};
componentWillReceiveProps(next_props) {
this.setState({toolbar: next_props.toolbar})
}
render () {
let bar = <div>{this.state.toolbar} undefined</div>;
switch (this.state.toolbar) {
case 'productToolbar':
bar = ProductToolbar;
break;
case 'salesToolbar':
bar = SalesToolbar;
break;
};
return (
<div className='toolbar show'>
{bar}
</div>
)
}
}
export default Toolbar;
productToolbar.js
import React from 'react';
export default class ProductToolbar extends React.Component {
render() {
return (
<div>
productToolbar
</div>
);
}
};
productPage.js
import React, {Component} from 'react';
...
class ProductPage extends React.Component {
componentDidMount() {
this.context.changeToolbar('productToolbar');
};
render() {
return (
<div>Page</div>
);
}
};
ComisionPage.contextTypes = {
changeToolbar: React.PropTypes.func
}
export default ProductPage;
when desire is loaded productPage.js create a special toolbar with options for Productpage.
I pass the name of the toolbar to render the new view, but it does not, missing or that I'm doing wrong?
another best solution was to pass directly toolbar
productPage.js
import ProductToolbar from '../components/toolbar/productToolbar';
...
componentDidMount() {
this.context.changeToolbar(ProductToolbar);
};
It not works for me

Just to make sure that you are rendering the element. Can you please change you switch statement to:
switch (this.state.toolbar) {
case 'productToolbar':
bar = <ProductToolbar />;
break;
case 'salesToolbar':
bar = <SalesToolbar />;
break;
};
Also, consider using a store (Redux, AltJs?) instead of context since they can get a bit complex on large apps (...I experienced the pain, until I switch to the 'store' approach)
