HTML form not sending data to node js
Question
I am trying to implement a html form which takes input and sends it to node js server but the html form is not sending any data to node js. It makes a request but no form data is sent.
I have an index.html file
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Input Form</title>
</head>
<body>
<h1>Send a message:</h1>
<form action="http://localhost:3000/action" method="POST">
<label for="data">Message:</label>
<input type="text" id="data" placeholder="Enter your message" name="text"/>
<input type="submit" value="Send message" />
</form>
</body>
</html>
and a node js file
//Modules
const fs = require ('fs');
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const http = require('http');
const actionRoute=require('./routes/action')
const server = http.createServer(app)
app.use(express.urlencoded({ extended: true }))
app.use(bodyParser.json())
app.all('/',(req,res)=>{
res.statusCode = 200;
res.setHeader('Content-Type', 'text/html');
res.end(fs.readFileSync('./public/index.html'))
})
const hostname = 'localhost';
const port = 3000
app.post('/action',(req,res)=>{
console.log(req.body)
res.statusCode=200;
res.end("thnx")
})
server.listen(port , hostname,function(){
console.log('Server running at http://'+hostname+':'+port);
});
Directory structure:
|
|-index.js
|-public
|--index.html
In the post route the req.body is empty it prints{}

I tried the exact same code and it worked perfectly. One possible reason why it didn't work for you is that the html form is on a different host, cross-origin requests aren't allowed by default. To allow all origins:
Install cors from npm
npm install cors
Use CORS middleware for your route
const cors = require('cors');
.
.
.
app.post('/action', cors(), (req, res) => {
console.log(req.body)
res.statusCode=200;
res.end("thnx")
});
