How to handle POST request on my http server in js? Allready answered

Question

I'm not sure how to explain it, but when I send a POST request to the server nothing happens. I'm missing the code on the server to handle the request.

I am only interested in http module (because I want to understand it before I move on to Express)

What to do from here?

My request:

fetch('http://127.0.0.1:5674', {
method: 'POST',
body: ' Anton',
headers: {"content-type": "text/plain"}
})
.then(response => console.log(response))
.catch(err => {
console.log('failed', err)
})

My server
let http = require('http');

const server = http.createServer((req, res) => {
if (req.method === 'POST'){
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end(req.body);
}
if (req.url === '/') {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('hello');
} else {
res.writeHead(404, { 'Content-Type': 'text/plain' });
res.end('404 Not Found');
}
});

server.listen(5674, '127.0.0.1', () => {
console.log('Server is running')
})

There's a lot to explain here .. let me save me some stress

The condition for checking for POST should be under a specific url path, for example

if (req.url == "/submit") {
if (req.method == "POST") {
// Do something
}
}

This will solve 90% of the problem . You can't just have that condition like that without specificying a path that requires POST request.

also, try to fetch from the frontend after clicking a button not at the top level of your server code.. it seems unreal doing it that way

I think you should take a look at this, and then concentrate on Express instead. It shows exactly how you handle a POST request.
