I have the following routes in the main.jsx (entry point),
import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route,IndexRoute, browserHistory } from 'react-router';
function render(){
ReactDOM.render((
<Router history={browserHistory}>
<Route path="/" component={Home} />
<Route path="/viewq/:id" component={v}/>
<Route path="/postq/:id" component={p}/>
</Router>
), document.getElementById("app"));
}
render();
when i access the following url e.g. host/viewq/id=14, the component is not getting rendered.
Have the following the the server.js file, to return the index.html that has the bundled file (main.js),
app.get('*', function (request, response){
response.sendFile(path.resolve(__dirname, 'dist', 'index.html'))
})
How to make this work ?

there are a few posts like this and I have tried other solutions such as adding a .htaccess file, and adding 'process.env.PUBLIC_URL' ahead of each route to get the relative route location, but nothing seems to be working with the new react-router-dom package which has been released...
The application will load the '/' login page no problem on startup in heroku, and in there a direct will move to another page, however after successful login I use 'window.location.assign("/Home")' to try to auto navigate back to the home page. This gets a 404 error.
Similarly, manually adding locations into the top bar also give 404 errors..
I have tried the fixes provided in other posts, but they are all for the old react-router-dom package (before they moved away from switch and started using BrowserRouter).
Can anyone help figure out why my router won't identify addresses added to the window location??
The application is currently deployed at https://dashboard.heroku.com/apps/octowatch-scratch

After hours of looking I've finally found the most up to date tool you are meant to use for react router in the latest update (currently 6.1.1)
This is about 3 posts down in this post (the other answers are all for older versions of react router and will not work)
The answer is simple:
import { useNavigate } from "react-router-dom";
then in your function add a simpler variable for useNavigate:
let navigate = useNavigate();
and replace your window.location.assign("/Home") with navigate("/Home", { replace: true });
(obviously could also just say useNavigate("/Home", {replace:true})
How do I get meteor to re-render my components when I sign in using the accounts-password package?
My react-router routes are:
import React, { Component } from 'react'
import ReactDOM from 'react-dom'
import { Router, Route, IndexRoute, browserHistory } from 'react-router'
import App from './containers/App'
import Recordings from './containers/Recordings'
import LandingPage from './containers/LandingPage'
import { BloodPressure } from '../collections/BloodPressure'
const routes = (
<Router history={browserHistory}>
<Route path="/" component={App}>
<IndexRoute component={LandingPage} />
<Route path="dashboard" component={Recordings} />
</Route>
</Router>
)
Meteor.startup( ()=> {
ReactDOM.render(routes, document.querySelector('.render-target'))
})
My App component is:
import React, { Component } from 'react'
import { createContainer } from 'meteor/react-meteor-data'
import { browserHistory } from 'react-router'
import Header from './Header'
class App extends Component {
constructor(props) {
super(props)
}
render() {
return(
<div>
<div className="ui four container">
<Header />
{this.props.children}
</div>
<div className="footer">
<p>Designed and Developed by Thomas Hoadley</p>
</div>
</div>
)
}
}
export default createContainer(() => {
return {
signedIn: Meteor.userId()
}
}, App)
When I sign in, I expect the page to automatically reload with the correct routes, however I am having to reload the page manually to redirect it.
Any help on this issue would be greatly appreciated!
Introduction
I am attempting to create an Isomorphic ReactJS application using React-Router and ExpressJS. This requires some modularity so both client and server has access to specific scripts such as the routes. The modularity is achieved through Browserify and the router guides I have followed are react-router lesson server rendering and react-router guide server rendering.
Problem
The router behaves differently when routes are imported from an external routes.jsx as opposed to being written in the same file as the router. The this.props.children is ignored when the routes are imported and the view replaces the whole app, while is honored when in the routes are in the same file and replaces only the subsection of the app (desired outcome).
Example
routes.jsx - For both server and client
import React from 'react';
import {Route, IndexRoute, Redirect} from 'react-router';
/* Base */
import App from './client.jsx';
/* Views */
import HomeView from '_view/HomeView';
import WorkView from '_view/WorkView';
const Routes = (
<Route path="/" component={App}>
<IndexRoute component={HomeView} />
<Redirect from="home" to="/" component={HomeView} />
<Route path="work" component={WorkView} />
</Route>
);
export default Routes;
client.jsx - Imported routes
When using imported Routes the whole of <main> is replaced with eg. HomeView rather than just {this.props.children}.
import React from 'react';
import {render} from 'react-dom';
import {Router, browserHistory} from 'react-router';
/* Routes */
import Routes from './routes.jsx';
/* Components */
import Header from '_component/Header';
/* Views */
import HomeView from '_view/HomeView';
import WorkView from '_view/WorkView';
export default class App extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<main>
<Header />
{this.props.children}
</main>
)
}
}
if(typeof window !== 'undefined' && typeof document !== 'undefined') {
render(<Router history={browserHistory} routes={Routes} />,
document.getElementById('root'));
}
client.jsx - Inline routes
When using inline Routes only {this.props.children} is replaced with eg. HomeView. However this removes the modularity and the server can no longer reach the routes. This means either export the routes from client.jsx or have two copies of the same rules. Neither of which I find appealing.
import React from 'react';
import {render} from 'react-dom';
import {Router, Route, IndexRoute, Redirect, browserHistory} from 'react-router';
/* Components */
import Header from '_component/Header';
/* Views */
import HomeView from '_view/HomeView';
import WorkView from '_view/WorkView';
export default class App extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<main>
<Header />
{this.props.children}
</main>
)
}
}
const Routes = (
<Route path="/" component={App}>
<IndexRoute component={HomeView} />
<Redirect from="home" to="/" component={HomeView} />
<Route path="work" component={WorkView} />
</Route>
);
if(typeof window !== 'undefined' && typeof document !== 'undefined') {
render(<Router history={browserHistory} routes={Routes} />,
document.getElementById('root'));
}
Question
Where does the error lie? With my code, with react-router, or with browserify's export method?
Turns out my inexperience with browserify caused this issue. As always with code it can be hard to debug what goes wrong but the answer was simple:
There is a circular reference,maybe here is the problem – gu mingfeng
Thank you, stackoverflow!
say, I have 2 pages, localhost and localhost/test, there's a link on localhost, which is to localhost/test.
localhost/test can be accessed via clicking the link, but when refreshing or input url localhost/test manually, it returns
Not Found
The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.
My code is like this:
import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, IndexRoute, Link, IndexLink, browserHistory } from 'react-router';
import session from 'express-session';
import $ from 'jquery';
const App = React.createClass ({
render() {
return (
<div>
Router lza.
<ul>
<li><Link to="test">Test</Link></li>
</ul>
</div>
);
}
})
const App2 = React.createClass ({
render() {
return (<div>Router lza.aasss</div>);
}
})
var routes = (
<Router history={browserHistory}>
<Route path="/">
<IndexRoute component={App} />
<Route path="/test" component={App2} />
</Route>
</Router>
)
ReactDOM.render(routes, document.getElementById("hello"))
How can it be solved?
I tried to solve it by express 4, but when I import express from 'express', it reports
Uncaught TypeError: Cannot read property 'prototype' of undefined
Thus I tried express-session, but I can't find a complete example of how to use it. Many examples has a var called 'app', but how it's defined? Or please just tell me how to make url can be accessed when refreshing. Thank you.
So as the title describes im doing an app available on github at denlillemand/react. It has a express backend that just serves a simple html template that imports my bundle.js. And the app initially renders just fine, but none of the routes seem to work.
Below is the components that are involved:
./Application.js
import React from "react";
import Marty from "marty";
import actions from "./actions";
import stores from "./stores";
import queries from "./queries";
import sources from "./sources";
import Router from "./Router";
import RealApp from "./components/App";
class Application extends Marty.Application {
constructor(options) {
super(options);
this.register(actions);
this.register(stores);
this.register(queries);
this.register(sources);
this.router = Router;
}
}
var app = new Application();
var { ApplicationContainer } = require('marty');
app.router.run(function(Handler,state){
React.render((
<ApplicationContainer app={app}>
<Handler{...state} />
</ApplicationContainer>
), document.getElementById("app"));
});
./components/App.js
import React from "react";
import Router from "react-router";
import Header from "./core/Header";
import Footer from "./core/Footer";
var RouteHandler = Router.RouteHandler;
export default class App extends React.Component {
constructor(props) {
super(props);
this.state = {
}
}
render() {
return (
<div>
<Header />
<RouteHandler />
<Footer />
</div>
);
}
}
./Routes.js
import React from "react";
import {Route} from "react-router";
import {DefaultRoute} from "react-router";
import App from "./components/App";
import About from "./components/About";
import ChapterOne from "./components/chapterone/ChapterOne";
import ChapterTwo from "./components/chaptertwo/ChapterTwo";
import ChapterThree from "./components/chapterthree/ChapterThree";
import ChapterFour from "./components/chapterfour/ChapterFour";
export default (
<Route name="app" path="/" handler={App}>
<Route path="/about" handler={About}/>
<Route path="/chapters/chapterone" handler={ChapterOne} />
<Route path="/chapters/chaptertwo" handler={ChapterTwo} />
<Route path="/chapters/chapterthree" handler={ChapterThree} />
<Route path="/chapters/chapterfour" handler={ChapterFour} />
<DefaultRoute name="default" handler={About}/>
</Route>
);
./Router.js
import Router from "react-router";
import routes from "./Routes";
let location = () => {
if(typeof window !== undefined){
return Router.historyLocation;
}
}
export default Router.create({
routes:routes,
location:location()
});
The default route seems to be the only one that works, since im hitting the About component. This app worked when it was SSR not long ago, and im kind of wondering if ive setup react-router correctly, but looking at the DOCS it seem like i have.
i guess i have to answer my own question,
The creator of MartyJS recently killed off his own project,
if you follow his twitter he announced it ..
so i guess im moving to redux since it has like 3500+ github starts i suppose it will be easier to find support for redux issues that arise .
Thanks .
