here is my html code:

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <script src="script.js"></script>
    <form action="/login" method="post">
        <input name="username" type="text" placeholder="username">
        <input name="password" type="password" placeholder="password">
        <button type="submit">Login</button>

and this is my server side code:

app.get('/login', (req, res) => {
    res.sendFile(__dirname + '/login.html')
})'/login', (req, res) => {
    const { username, password } = req.body
    const foundUser = users.find(u => {
        return u.username === username
    if(foundUser.password !== password) {
        res.send('wrong password')
    } else {
        const accessToken = jwt.sign({ 
            username: foundUser.username, 
            password: foundUser.password
        }, jwtSecret)
            accessToken: accessToken
<pre lang="text">so after I make a post request to /login route and log in, my server will respond with some JSON data but I'm not sure how to get or access that data from the client side. should I do it from script.js? if so how should I do it? I would appreciate any help

What I have tried:

i've tried using fetch to fetch json response

hello !

are you looking for 'ajax' response ?

in your code , by 'get' / 'post' , you're requesting synchronous response ( with a reload of the page ), this way you have to handle the response in the same page script.
