I am making a website with ReactJS and I am using react-router v4 to navigate through website pages.
I am trying to use nested routes to achieve the same result as shown in the diagram I uploaded.
To be more clear, I want to have some kind of layout component where the header and footer stay the same, and only the content in the middle is changed with every click to the next or previous button. The 'home_page' and the 'create_record' page have the same layout, and the 3 step pages share another layout from the home_page. It's like the Airbnb style layout and navigation.
Any suggestion on how can I achieve this?
Here is my solution. This might not so effective but this is working on me.
So my strategy is get the window url and check the step.
In here I create 8 files.
Header
Footer
Home.js
NewRecord.js
Steps.js
StepOne.js
StepTwo.js
StepThree.js
I will describe only the App.js and the Steps.js. Others is up to you.
App.js
import React from 'react'
import ReactDOM from 'react-dom'
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom'
import Home from './Home'
import NewRecord from './NewRecord'
import Steps from './Steps'
const App = () => {
return (
<Router>
<Switch>
<Route exact path="/" component={Home}/>
<Route exact path="/new_record" component={NewRecord}/>
<Route path="/new_record/step_1" component={Steps}/>
<Route path="/new_record/step_2" component={Steps}/>
<Route path="/new_record/step_3" component={Steps}/>
</Switch>
</Router>
)
}
export default App
Steps.js
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import Header from './Header';
import Footer from './Footer';
import StepOne from './StepOne';
import StepTwo from './StepTwo';
import StepThree from './StepThree';
export default class Steps extends Component {
constructor (props) {
super(props)
this.state = {
url : window.location.href,
currentStep: 0
}
}
checkCurrentStep = () => {
// check the url using javascript search() method
if (this.state.url.search('step_1') != -1) {
this.state.currentStep = 1;
} else if (this.state.url.search('step_2') != -1) {
this.state.currentStep = 2;
} else {
this.state.currentStep = 3;
}
}
componentWillMount () {
this.checkCurrentStep()
}
render() {
return (
<div>
<Header />
{ (this.state.currentStep == 1) ? <StepOne /> :
(this.state.currentStep == 2) ? <StepTwo /> :
<StepThree />
}
<Footer />
</div>
);
}
}

I have a create profile page and an auth page (where one enters a code sent by text). I'd like to navigate to the auth page, when a profile is created.
I have a component for the create profile page and one for the auth page.
Based on the example here.
Relevant code:
// CreateProfileComponent.js
import React from 'react';
..
import { withRouter } from "react-router";
class CreateProfile extends React.Component {
constructor(props) {
super(props);
}
handleCreateProfile(e) {
e.preventDefault();
if (condition) {
createProfile(...);
this.props.history.push('/auth');
} else {
// re-render
}
}
render() {
return (
// data-testid="create-profile" - workaround (https://kula.blog/posts/test_on_submit_in_react_testing_library/) for
// https://github.com/jsdom/jsdom/issues/1937
<form onSubmit={this.handleCreateProfile.bind(this)} data-testid="create-profile">
...
</form>
);
}
}
export default withRouter(CreateProfile);
// index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router, Route } from 'react-router-dom';
import CreateProfile from './CreateProfileComponent';
import { TokenEntry } from './TokenEntryComponent';
ReactDOM.render(
<Router>
<ProtectedRoute exact path="/" component={ActivityList} />
<Route path="/login" component={CreateProfile.WrappedComponent} />
<Route path="/auth" component={TokenEntry} />
</Router>,
document.getElementById('root')
);
//createprofilecomponent.test.js
import React from 'react';
import {
LocationProvider,
createMemorySource,
createHistory
} from '#reach/router';
import { render, screen, fireEvent } from '#testing-library/react';
import CreateProfile from '../CreateProfileComponent';
const source = createMemorySource('/login');
const history = createHistory(source);
let displayName = null;
let phoneNumber = null;
let legalAgreement = null;
global.window = { location: { pathname: null } };
function Wrapper({children}) {
return <LocationProvider history={history}>{children}</LocationProvider>;
}
beforeEach(() => {
render(
<CreateProfile.WrappedComponent location={'/'} />,
{ wrapper: Wrapper }
);
});
it("navigates to /auth when good data entered", () => {
// setup
fireEvent.submit(screen.getByTestId('create-profile'));
expect(global.window.location.pathname).toEqual('/auth');
});
I'm getting
TypeError: Cannot read property 'push' of undefined
during tests and in Chrome.
What am I missing?
Use the react-router-dom
import { withRouter } from "react-router-dom";
Changed
export default withRouter(CreateProfile);
To
export const CreateProfileWithRouter = withRouter(CreateProfile);
Changed
<Route path="/login" component={CreateProfileWithRouter.WrappedComponent} />
To
<Route path="/login" component={CreateProfileWithRouter} />
Pull request created to include an example in withRouter's documentation.
Example gist
I am trying to make a single web application. Basically, I am trying to use the ReactRouter to display what is passed as a Route Parameter. However, I am unable to do that. To check if somethings wrong, I decided to console.log out this.props.match, still nothing shows up. Could someone explain what the problem is? And a possible get around?
My code is-
import React from 'react';
export default class Post extends React.Component {
state = {
id: null
}
componentDidMount(props) {
console.log(this.props.match);
}
render = () => {
return (<div>Hello WOrld</div>)
}
}
The App.js file:
import React, { Fragment, Component } from 'react';
import Navbar from './components/Navbar';
import Home from './components/Home';
import Contact from './components/Contact';
import About from './components/About'
import Post from './components/Post';
import { BrowserRouter, Route } from 'react-router-dom';
class App extends Component {
render = () => {
return (
<BrowserRouter>
<div className="App">
<Navbar />
<Route exact path="/" component={Home} />
<Route path="/contact" component={Contact} />
<Route path="/about" component={About} />
<Route path="/:post-id" component = {Post} />
</div>
</BrowserRouter>
);
}
}
export default App;
I just ran your code on my end, it looks like the problem is using /:post-id. I changed that to /:pid and it worked. I got the below object when I console log this.props.match
{
"path":"/:pid",
"url":"/1",
"isExact":true,
"params":
{
"pid":"1"
}
}
I hope this helps.
You have to load the component with router
try this
import { withRouter } from 'react-router-dom';
class Post extends React.Component {
state = {
id: null
}
componentDidMount(props) {
console.log(this.props.match);
}
render = () => {
return (<div>Hello WOrld</div>)
}
}
export default withRouter(Post);
I'm trying to build a simple example project where the user is redirected to the 'contact' page upon clicking a button, using React. I'm trying to achieve this by setting the value of a state property. When I run the code I have, it does change the browser address bar URL to that of the contact page, but does not seem to actually load the component - I get a blank page instead. If I manually navigate to that URL (http://localhost:3000/contact) I can see the contents.
Here are my App.js and Contact.js files -
App.js
import React, { Component } from 'react';
import { BrowserRouter as Router, Switch, Route, Link, Redirect } from 'react-router-dom';
import Contact from './Contact';
class App extends Component {
state = {
redirect: false
}
setRedirect = () => {
this.setState({
redirect: true
})
}
renderRedirect = () => {
if (this.state.redirect) {
return <Redirect to='/contact' />
}
}
render() {
return (
<Router>
<Switch>
<Route exact path='/contact' component={Contact} />
</Switch>
<div>
{this.renderRedirect()}
<button onClick={this.setRedirect}>Redirect</button>
</div>
</Router>
)
}
}
export default App;
Contact.js
import React, { Component } from 'react';
class Contact extends Component {
render() {
return (
<div>
<h2>Contact Me</h2>
<input type="text"></input>
</div>
);
}
}
export default Contact;
Using state isn't really a requirement for me, so other (preferably simpler) methods of redirection would be appreciated too.
Since your button is nothing more than a link, you could replace it with:
<Link to="/contact">Redirect</Link>
There are many alternatives though, you could for example look into BrowserRouter's browserHistory:
import { browserHistory } from 'react-router'
browserHistory.push("/contact")
Or perhaps this.props.history.push("/contact").
There are pros and cons to every method, you'll have to look into each and see which you prefer.
I got here for a similiar situation. It's possible use withRouter (https://reactrouter.com/web/api/withRouter) to handle that.
This example was tested with "react": "^16.13.1","react-router-dom": "^5.2.0" and "history": "^5.0.0" into "dependecies" sections in package.json file.
In App.js I have the BrowserRouter (usually people import BrowserRouter as Router, I prefer work with original names) with Home and Contact.
App.js
import React, { Component } from "react";
import {
BrowserRouter,
Switch,
Route,
} from "react-router-dom";
import Home from "./pages/Home";
import Contact from "./pages/Contact";
class App extends Component
{
// stuff...
render()
{
return (
<BrowserRouter>
<Switch>
<Route path="/contact">
<Contact />
</Route>
<Route path="/">
<Home />
</Route>
</Switch>
</BrowserRouter>
);
}
}
export default App;
ASIDE 1: The Route with path="/contact" is placed before path="/" because Switch render the first match, so put Home at the end. If you have path="/something" and path="/something/:id" place the more specific route (with /:id in this case) before. (https://reactrouter.com/web/api/Switch)
ASIDE 2: I'm using class component but I believe (I didn't test it) a functional component will also work.
In Home.js and Contact.js I use withRouter associated with export keyword. This makes Home and Contact components receive the history object of BrowserRouter via props. Use method push() to add "/contact" and "/" to the history stack. (https://reactrouter.com/web/api/history).
Home.js
import React from "react";
import {
withRouter
} from "react-router-dom";
export const Home = ( props ) =>
{
return (
<div>
Home!
<button
onClick={ () => props.history.push( "/contact" ) }
>
Get in Touch
<button>
</div>
);
}
export default withRouter( Home );
Contact.js
import React from "react";
import {
withRouter
} from "react-router-dom";
export const Contact = ( props ) =>
{
return (
<div>
Contact!
<button
onClick={ () => props.history.push( "/" ) }
>
Go Home
<button>
</div>
);
}
export default withRouter( Contact );
Particularly, I'm using also in a BackButton component with goBack() to navigate backwards:
BackButton.js
import React from "react";
import {
withRouter
} from "react-router-dom";
export const BackButton = ( props ) =>
{
return (
<button
onClick={ () => props.history.goBack() }
>
Go back
<button>
);
}
export default withRouter( BackButton );
So I could modify the Contact to:
Contact.js (with BackButton)
import React from "react";
import BackButton from "../components/BackButton";
export const Contact = ( props ) =>
{
return (
<div>
Contact!
<BackButton />
</div>
);
}
export default Contact; // now I'm not using history in this file.
// the navigation responsability is inside BackButton component.
Above was the best solution for me. Other possible solutions are:
useHistory Hook (https://reactrouter.com/web/api/Hooks)
work with Router instead BrowserRouter - (https://reactrouter.com/web/api/Router)
First off, I have read through just about every example I can find and looked through various boilerplates to see how others have done this. I am having issues loading pages when clicking <Link>'s with react-router v4. I have also installed the package react-router-connected and have been trying that out as well but no improvement can be seen (however it shows the changes in the redux-logger which is nice).
Currently, the url updates just fine and if I manually change the url and press enter, then the next page will load. But, it will not redirect if I click a link. I am also using create-react app for the project, just for your reference. My actual app is setup as the exact example from usage with react-router in the official redux docs. For simplicity, I have changed my routes to only include links to basic components that do nothing but redirect to one another.
Root.js which houses my routes
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from "react-router-dom";
import { Provider } from 'react-redux';
import { ConnectedRouter } from 'connected-react-router'
// import App from './App';
import NewComponent from './NewComponent';
import OldComponentent from './OldComponent';
const Root = ({ store, history }) => (
<Provider store={store}>
<ConnectedRouter history={history}>
<Router>
<Switch>
<Route exact path='/' component={OldComponentent}/>
<Route path='/new' component={NewComponent}/>
{/* <Route path='/' component={App}/>
<Route path='/:filter' component={App}/> */}
</Switch>
</Router>
</ConnectedRouter>
</Provider>
)
export default Root;
Home component
import React from 'react';
import { connect } from 'react-redux';
import { push } from 'connected-react-router';
import { withRouter } from 'react-router';
import { Link } from 'react-router-dom';
import Button from 'material-ui/Button';
class OldComponent extends React.Component {
redirectPage = () => { this.props.dispatch(push('/new')); };
redirectPage1 = () => { this.props.dispatch(push('/')); };
render() {
return (
<div>
OLD COMPONENT
<Button onClick={this.redirectPage}>Redirect new</Button>
<Button onClick={this.redirectPage1}>Redirect /</Button>
<Link to='/new'>Redirect Link</Link>
</div>
)
}
}
export default withRouter(connect()(OldComponent));
Other basic component for redirection purposes
import React from 'react';
import { connect } from 'react-redux';
import { push } from 'connected-react-router';
import { withRouter } from 'react-router';
import { Link } from 'react-router-dom';
import Button from 'material-ui/Button';
class NewComponent extends React.Component {
redirectPage = () => { this.props.dispatch(push('/')); };
redirectPage1 = () => { this.props.dispatch(push('/new')); };
render() {
return (
<div>
NEW COMPONENT
<Button onClick={this.redirectPage}>Redirect /</Button>
<Button onClick={this.redirectPage1}>Redirect new</Button>
<Link to='/new'>Redirect Link</Link>
</div>
)
}
}
export default withRouter(connect()(NewComponent));
As you can see, they are essentially the same component with minor differences. The url will change to /new or / and will also update the pathname found in the ##router/LOCATION-CHANGE state objects created by react-router-connected package. The url will also change by clicking the <Link> tag but with no redirect.
Any help on how to approach this would be greatly appreciated.
The comment posted by #Supertopoz works this.props.history.push('/pathname') works. However, after setting that up, the <Link> now works as well. I am also using withRouter (which I was before) throughout, so that was another important factor in egtting it to work.
I am having some trouble with a component not rendering after following its route. The routes are created in a parent component Drawings, and send a couple of props to Drawing components.
When I click the link, I get to the correct path, for example, /drawing/20170724, and the log statement I have in the render function runs. I also get the props, so far so good. However, the return doesn't happen, so the HTML I need isn't available.
Here is Drawings where the routes and links are created:
import React, { Component } from "react";
import { Route, Link } from "react-router-dom";
import AnimatedWrapper from "../modules/AnimatedWrapper";
import Drawing from '../components/Drawing';
class DrawingsComponent extends Component {
render() {
const drawings = this.props.drawings;
const drawingsMap = this.props.drawingsMap;
return(
<div>
<div className="page">
<div className="drawings-list">
{
drawings.map((drawing) => {
return(
<Link to={`/drawing/${drawing.date}`} key={drawing.date}>
<div className="drawing-thumb">
<h2>{drawing.date}</h2>
</div>
</Link>
)
})
}
</div>
{
Object.keys(drawingsMap).map((d, i) => {
return <Route path={`/drawing/${drawings[i].date}`} render={(props) => (<Drawing drawingPkg={drawingsMap[d]} drawingInfo={drawings[i]} {...props} />)} key={`${drawings[i].date}`}/>
})}
</div>
</div>
)
}
}
const Drawings = AnimatedWrapper(DrawingsComponent);
export default Drawings;
And here is Drawing:
import React, { Component } from 'react';
import AnimatedWrapper from "../modules/AnimatedWrapper";
class DrawingComponent extends Component {
render() {
const drawing = this.props.drawingPkg;
const drawingInfo = this.props.drawingInfo;
console.log('gonna draw now');
return(
<div className="drawing">
<h2 className="drawing-title">{drawingInfo.title}</h2>
<canvas></canvas>
</div>
)
}
}
const Drawing = AnimatedWrapper(DrawingComponent);
export default Drawing;
I can't figure out why the Drawing component isn't returning.
What you are doing is wrong. You change the URL when the link is clicked. Then you have to give routes configuration, that tells react router which component to render when the URL changes. It should be something like this inside your index.js file.
import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import { BrowserRouter, Route, Switch } from 'react-router-dom';
import promise from 'redux-promise';
import reducers from './reducers';
import Drawing './components/drawing_component';
const createStoreWithMiddleware = applyMiddleware(promise)(createStore);
ReactDOM.render(
<Provider store={createStoreWithMiddleware(reducers)}>
<BrowserRouter>
<div>
<Switch>
<Route path="/drawings/:date" component={Drawing} />
<Route path="/" component={IndexComponent} />
</Switch>
</div>
</BrowserRouter>
</Provider>
, document.querySelector('.container'));
I think what is wrong here is your routes config. I have never seen route config is given like the way you do.
Then write a separate Drawing component which renders a given drawing instance.
With this change your Link should be like this.
<Link to={`/drawing/${drawing.date}`}>
{drawing.date}
</Link>
The bottom line is this. Here you give some text with a hyperlink. Upon clicking this router changes the URL as in your case now. Then it uses router config to render the relevant component.
