I Have a React web app that has crypto portfolio, Now I want to connect it with Backend server.js. The deployed web app should set start from Node Server. I am fairly new with NodeJS but Ive tried solutions like cors and all.
I am Fairely New to node can anyone please help me to connect my React folder to backend node folder. I'll be very grateful.
In react I've made Production Build also but it didn't worked.
Here's Server.js Code:
const express = require('express');
const cors = require('cors');
const path = require('path');
app.use(express.json({ extended: false }));
app.use((req, res, next) => {
res.header('Access-Control-Allow-Origin', '*');
res.header(
'Access-Control-Allow-Headers',
'Origin, X-Requested-With, Content-Type, Accept'
);
next();
});
if (process.env.NODE_ENV === 'production') {
//static folder
app.use(express.static('client/build'));
app.get('/', (req, res) => {
res.sendFile(path.resolve(__dirname, 'client', 'build', 'index.html'));
});
}
Now I am Getting the error in server
connot GET /

If you are starting the server using the code app.listen(3000);
And it's still not working, then you might have to set the environment variable NODE_ENV=production
you can do it like this NODE_ENV=production node server.js
Better practice will be to keep all you environment variables inside a .env
file and then use the dotenv
package to read the environment variables from the .env
file
