How to do server side rendering in react despite all react router version conflicts?
Question
I am trying to server-side rendering with react and react-router-dom I've done this before but with the new version, it is throwing me an error You should not use Switch outside a Router I think it is a version conflict but is there a solution ( react-router-config - You should not use outside a (it is inside a Router!) ).
server.js
import express from 'express';
import React from 'react';
import ReactDOMServer from 'react-dom/server';
import App from '../client/src/AppRoutes';
import { StaticRouter } from 'react-router-dom';
import { renderRoutes } from 'react-router-config'
const app = express();
app.get('*', (req, res) => {
const routerContext = {};
res.send(`
<!doctype html>
<html lang="en">
<head>SSR</head>
<body>
<div id="root">${ReactDOMServer.renderToString(
<StaticRouter location={req.url} context={routerContext}>
<div>{renderRoutes(App)}</div>
</StaticRouter>
)}</div>
<!-- <script src="/dist/main.js"></script>-->
</body>
</html>
`);
});
app.listen(3000, (error) => {
if (error) {
return console.log('something bad happened', error);
}
console.log("listening on " + 3000 + "...");
});
AppRoutes.js
import PageA from './Container/PageA';
import PageB from './Container/PageB';
import Home from './Container/Home'
import MainPage from './Container/MainPage';
export default [
{
...MainPage,
routes:[
{
...Home,
path:'/',
exact:true
},
{
...PageA,
path:'/a',
exact:true
},
{
...PageB,
path:'/b',
exact:true
}
]
}
]

Quick fix:
- Remove your
node_modules - Add
"react-router": "^5.0.1"to yourpackage.json - Re-install with
npm install.
Ensure that react-router , react-router-config , react-router-dom are in the same version.
What is wrong?
When I try to reproduce your error, I figure out that your package.json in the question is missing react-router dependency, which makes me unable to start the server.
And from your story, I guess that you have another version of react-router in your node_modules , which is out of sync with react-router-config and react-router-dom version 5.0.1.
So I try to reproduce the problem with this:
"react-router": "^4.3.0",
"react-router-config": "^5.0.1",
"react-router-dom": "^5.0.1"
Which will lead to the problem you mentioned.
