Fix cannot GET /url react router

Question

const express = require('express')
const cors = require('cors')
const path = require('path');

const app = express()

app.use(express())
app.use(cors())
app.use(express.static(path.join(__dirname, 'client/build')))

app.get('/', (req, res)=>{
    console.log('server is up')
})

app.get('/data', (req, res)=>{
    res.send({name: 'name', age: 'age' })
})

app.listen(5000)

I am getting cannot Get /URL. I want to run build index.html file with express. React Router is not working. Any idea how to fix it?

You should be routing all the request to the index.html assuming its a SPA(Single Page Application)

like this:

app.get('*', function(req, res) {
  res.sendFile('index.html', {root: path.join(__dirname, '../../client/build/')});
});

It is not a single page application.
