I want to send values from react to node. I am using fetch but I am not getting. Here's the code: React Code:
const values = {email,pass}
const data = {
method: 'POST',
headers: {
"Content-Type": "application/json"
},
body: JSON.stringify(values),
}
fetch('http://localhost:8000/', data)
.then(res => res.json())
.then(data => console.log(data))
Node Code:
const express = require("express")
const cors = require('cors')
const app = express()
app.use( cors({ origin: '*' }) )
app.listen(8000, 'localhost')
app.post('/' , ( req, res ) => {
console.log(req.body)
} )
When I am visiting to this http://localhost:8000/ i am getting an error Cannot GET /
You need express to use json body parser:
app.use(express.json());
Additionally you are not sending any response from your Node Server to the client, try something like this this:
app.post('/' , ( req, res ) => {
console.log(req.body)
const data = JSON.stringify(req.body)
console.log(data)
res.status(200).json({data: data});
})
use json body parser:
app.use(express.json());
