I'm tying to convert old react router code.
I cannot find a place that explains how to update old react router code.
How the code below can be translated using "react-router": "^4.2.0" ?
Sample code from app-client.js :
var Router = require('react-router');
var Route = Router.Route;
var DefaultRoute = Router.DefaultRoute;
var routes = (
<Route handler={APP}>
<DefaultRoute handler={Audience} />
<Route name="speaker" path="speaker" handler={Speaker}></Route>
<Route name="board" path="board" handler={Board}></Route>
</Route>
);
Router.run(routes, function(handler) {
ReactDOM.render(<APP />, document.getElementById('react-container'));
});
Sample code from APP.js :
var Router = require('react-router');
var RouteHandler = Router.RouteHandler;
var APP = createReactClass({
render() {
return(
<div>
<Header title={this.state.title} status={this.state.status} />
<RouteHandler />
</div>
);
}
});
module.exports = APP;

My react router is not opening my news and photos pages. When they open it's supposed to display the header file on each pages. When I try to open the news page (localhost:8080/news) I get a 404 page not found error message in my node command prompt.
My GitHub repository
var React = require('react');
var ReactRouter = require('react-router');
var Router = ReactRouter.Router;
var Route = ReactRouter.Route;
var browserHistory = ReactRouter.browserHistory;
var Header = require('./components/Header.jsx');
var News = require('./components/News.jsx');
var Photos = require('./components/Photos.jsx');
var Routes = (
<Router history={browserHistory}>
<Route path="/" component={Header}>
<Route path="news" component={News} />
<Route path="photos" component={Photos} />
</Route>
</Router>
);
module.exports = Routes;
Here's a quick answer of what you can do to your main.js file. There's probably better ways you could structure your code. I would suggest taking a closer look at more React examples around the Internet.
'use strict';
var React = require('react');
var ReactDOM = require('react-dom');
var Routes = require('./Routes.jsx');
var Header = require('./components/Header.jsx');
var Main = React.createClass({
render: function(){
return(
<div>
<Header />
<Routes />
</div>
);
}
});
ReactDOM.render(<Main />, document.getElementById('switch'));
I noticed your code seems to have a lot of duplicate files for a .js and a .jsx. You know you only need one or the other, right?
I found out I was using react-router v3.0 so I uninstalled it and installed the 2.8.1 version. It still displays the # (ie. localhost/#/news) but it's close enough. Thanks for your help.
var React = require('react');
var ReactRouter = require('react-router');
var Router = ReactRouter.Router;
var Route = ReactRouter.Route;
var useRouterHistory = ReactRouter.useRouterHistory;
var createHashHistory = require('react-router/node_modules/history/lib/createHashHistory');
var appHistory = useRouterHistory(createHashHistory)({
queryKey:false
});
var Header = require('./components/Header.jsx');
var News = require('./components/News.jsx');
var Photos = require('./components/Photos.jsx');
var Routes = (
<Router history={appHistory}>
<Route path="/" component={Header}>
<Route path="/news" component={News} />
<Route path="/photos" component={Photos} />
</Route>
</Router>
);
module.exports = Routes;
I'm working with react router, but I have a problem when I try to reload some views. This is my code
Router file
var React = require('react');
var ReactRouter = require('react-router');
var Router = ReactRouter.Router;
var Route = ReactRouter.Route;
var IndexRoute = ReactRouter.IndexRoute;
/*Windows*/
var Index = require('./components/views/Index.jsx');
var RegisterForm = require('./components/views/RegisterForm.jsx');
var Base = require('./components/Base.jsx');
var Intro = require('./components/views/Intro.jsx');
var ProductsView = require('./components/views/ProductsView.jsx');
var SuccessfullyRegistered = require('./components/views/SuccessfullyRegistered.jsx');
var Cart = require('./components/views/Cart.jsx');
var EditAccount = require('./components/views/EditAccount.jsx');
var BuyStep01 = require('./components/views/BuyStep01.jsx');
var NotFoundPage = require('./components/views/NotFoundPage.jsx');
var browserHistory = ReactRouter.browserHistory;
var hashHistory = ReactRouter.hashHistory;
var Routes = (
<Router history={browserHistory}>
<Route path="/" component={Base}>
<IndexRoute component={Intro}/>
<Route path="index" component={Index}/>
<Route path="register" component={RegisterForm}/>
<Route path="success" component={SuccessfullyRegistered}/>
<Route path="product" component={ProductsView}/>
<Route path="cart" component={Cart}/>
<Route path="editaccount" component={EditAccount}/>
<Route path="step01" component={BuyStep01}/>
<Route path="*" component={NotFoundPage}/>
</Route>
</Router>
);
module.exports = Routes;
My base file
var React = require('react');
var Footer = require('../components/footer/Footer.jsx');
var SocialNetsBox = require('../components/socialNets/SocialNetsBox.jsx');
var Base = React.createClass({
render: function(){
var style={
overflowX: 'hidden'
};
var styleHidden={
overflow: 'hidden'
};
return(
<div className="father">
<SocialNetsBox/>
<div className="container-fluid" style={style}>
{this.props.children}
</div>
<Footer/>
</div>
);
}
});
module.exports = Base;
and my mainfile.
var React = require('react');
var ReactDOM = require('react-dom');
var Routes = require('./Routes.jsx');
ReactDOM.render(Routes, document.getElementById('main'));
The problem is that when I press F5 or refresh icon in browser, I get a blank page without any error in console. I don't know what's happening. I'm using http-server
This seems to be a common case of RFP rabbitholing. You just need to reset the cache packet server ratio and everything should work after that.
React-router is off to a really bad start... What seems basic doesn't work. Using react-router 2.0.0 my Link component updates the URL to be /about, but my page doesn't render the About component after that...
Entry point js
var React = require('react');
var ReactDOM = require('react-dom');
var Router = require('react-router').Router;
var Route = require('react-router').Route;
var hashHistory = require('react-router').hashHistory;
var App = require('./components/App.react');
var About = require('./components/About');
ReactDOM.render(
<Router history={hashHistory} >
<Route path="/" component={App}>
<Route path="about" component={About} />
</Route>
</Router>,
document.getElementById('app')
);
App.js
'use strict';
var React = require('react');
var Link = require('react-router').Link;
var Header = require('./Header');
var UserPanel = require('./UserPanel');
var ModelPanel = require('./ModelPanel.react');
var EventPanel = require('./event/EventPanel');
var VisPanel = require('./vis/VisPanel');
var LoginForm = require('./LoginForm');
var AppStore = require('../stores/AppStore');
var AppStates = require('../constants/AppStates');
var App = React.createClass({
[... code omitted ...]
render: function() {
var viewStateUi = getViewStateUi(this.state.appState);
return (
<div>
<Header />
<Link to="/about">About</Link>
{viewStateUi}
</div>
);
}
});
For some reason, the <Link>s were not working for me with the configuration below.
// index.js
ReactDOM.render(
<Provider store={store}>
<BrowserRouter >
<App />
</BrowserRouter>
</Provider>,
document.getElementById('root')
);
// App.js
return (
<div className="App">
<Route exact={true} path="/:lang" component={Home} />
<Route exact={true} path="/" render={() => <Redirect to={{ pathname: 'pt' }} />} />
<Route path="/:lang/play" component={Play} />} />
<Route path="/:lang/end" component={End} />
</div >
);
The Home component had the Link, but Links on the App would do the same. Every time I clicked it, it would only change the url, but the views would stay the same.
I was able to put it working when I added withRouter to the App.js
export default withRouter(connect(mapStateToProps, { f, g })(App));
I still don't understand what happened. Maybe it's related with redux or there is some detail I'm missing.
Since the 'About' route is a child of the 'App' route, you need to either add this.props.children to your App component:
var App = React.createClass({
render: function() {
var viewStateUi = getViewStateUi(this.state.appState);
return (
<div>
<Header />
<Link href="/about">About</Link>
{viewStateUi}
{this.props.children}
</div>
);
}
});
or separate your routes:
ReactDOM.render(
<Router history={hashHistory} >
<Route path="/" component={App} />
<Route path="/about" component={About} />
</Router>,
document.getElementById('app')
);
None of the solutions worked for me, including adding withRouter to my Component. I was experiencing the same issue where the browser's address bar updates the URL but the component doesn't render. During the debugging of my issue, I realize I have to present the context of my problem because it is a bit different from what the OP had.
The route I was trying to get to work was a dynamic route that takes an arbitrary parameter, e.g.
<Route path={`/hr/employees/:id`} component={EmployeePage} />
The component this route uses is "self-referential", meaning that within the component or its children components, they have a Link component that directs to /hr/employees/:id, but with a different id. So let's say if I was at /hr/employees/3 and on the page, there was a link to /hr/employees/4, e.g. <Link to='/hr/employees/4'>, I would get this problem where the component didn't re-render.
To solve this problem, I simply modified the componentDidUpdate method of my EmployeePage component:
componentDidUpdate(prevProps) {
if (this.props.match.params.id !== prevProps.match.params.id) {
// fetch data
}
}
If you're using functional components, use useEffect:
const EmployeePage = props => {
const {id} = props.match.params
useEffect(() => {
// fetch data
}, [id])
}
I am getting this error :-
Uncaught TypeError: Cannot read property 'createRouteFromReactElement' of undefined
in this code. I used Router for navigation but not working. I imported a file called Home.jsx
var React = require('react')
var ReactDOM = require('react-dom')
var Router = require('react-router').Router
var Route= Router.Route
var IndexRoute = Router.IndexRoute
var App = React.createClass({
render() {
return (
<div>
<p>App</p>
<ul>
<li>About</li>
</ul>
</div>
)
}
})
var About = require('./components/Home')
ReactDOM.render((
<Router>
<Route path="/" component={App}>
<IndexRoute path="/about" component={About} />
</Route>
</Router>
), document.body)
and Home.jsx
var React = require('react');
var RaisedButton = require('material-ui/lib/raised-button');
var Home = React.createClass({
render:function() {
return (
<RaisedButton label="Default" />
);
},
});
module.exports = Home;
There are a few things which you are doing wrong here. I'm assuming you are using React Router 1.0 (because of use of IndexRoute).
In version 1.0 Router component is a property of the top-level module, so this is how you would do your imports:
var ReactRouter = require('react-router');
var Router = ReactRouter.Router;
var Route = ReactRouter.Route;
var IndexRoute = ReactRouter.IndexRoute;
I think you also not fully understand what IndexRoute is, have a look in the docs for the clarification. But the tldr; is that the IndexRoute does not take the path argument.
Another thing is that to mount your routes components somewhere you need to specify where, and you can do it with use of {this.props.children}. So your could could look like:
var React = require('react');
var ReactDOM = require('react-dom');
var ReactRouter = require('react-router');
var Router = ReactRouter.Router;
var Route = ReactRouter.Route;
var IndexRoute = ReactRouter.IndexRoute;
var App = React.createClass({
render() {
return (
<div>
<p>App</p>
{this.props.children}
</div>
)
}
})
var About = require('./components/Home')
ReactDOM.render((
<Router>
<Route path="/" component={App}>
<IndexRoute component={About} />
</Route>
</Router>
), document.body)
Please have a look at the Introduction docs so you will better understand how to use react router in your app.
I am trying to figure out React Router, but when I load the page I am only seeing an empty script tag being rendered. I must be doing something wrong. I have followed the guide on the react router docs page.
var React = require('react');
var Router = require('react-router');
var Route = Router.Route;
var RouteHandler = Router.RouteHandler;
var About = require('./About');
var Inbox = require('./Inbox');
var routes = (
<Route handler={App}>
<Route path="about" handler={About}/>
<Route path="inbox" handler={Inbox}/>
</Route>
);
var App = React.createClass({
render () {
return (
<div>
<h1>App</h1>
<RouteHandler/>
</div>
)
}
});
Router.run(routes, Router.HashLocation, (Root) => {
React.render(<Root/>, document.getElementById('app'));
});
I figured it out. I needed to put my routes variable below App like so:
var React = require('react');
var Router = require('react-router');
var Route = Router.Route;
var RouteHandler = Router.RouteHandler;
var About = require('./About');
var Inbox = require('./Inbox');
var App = React.createClass({
render () {
return (
<div>
<h1>App</h1>
<RouteHandler/>
</div>
)
}
});
var routes = (
<Route handler={App}>
<Route path="about" handler={About}/>
<Route path="inbox" handler={Inbox}/>
</Route>
);
Router.run(routes, Router.HashLocation, (Root) => {
React.render(<Root/>, document.getElementById('app'));
});
