How can I dix this Node.js login page?

Question

I'm breaking my head with a Node js with mysql database and trying to make a simple login.

I am getting :Cannot POST /login

<body class="hero-image">

<div id="container">
    <div id="tabs">

       <p id="lt" class="tabs">Log in</p>
        <p id="rt" class="tabs" onclick="location.href = './register';">Register</p>

        <div id="clear"></div>
    </div>
    <div id="cont">
        <div id="loginBox" class="comm">
            <h3>Sign in</h3>
            <form action="login" method="POST">
                <input id="username" type="text" autocomplete="off" name="username" placeholder="Username" required>
                <input id="password" type="password" autocomplete="off" name="password" placeholder="Password" required>
                <input type="submit" value="Submit Form">
            </form>
        </div>
    </div>
</div>
<script>
        const form = document.getElementById('login')
        form.addEventListener('submit', login)

        async function login(event) {
            alert('Success')
            event.preventDefault()
            const username = document.getElementById('username').value
            const password = document.getElementById('password').value
            
            
            
            const result = await fetch('/api/login', {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json'
                },
                body: JSON.stringify({
                    username,
                    password
                })
            }).then((res) => res.json())

            if (result.status === 'ok') {
                // everythign went fine
                console.log('Got the token: ', result.data)
                localStorage.setItem('token', result.data)
                alert('Success')
            } else {
                if (result.status === 'Not Found') {
                    alert("Incorrect Username and/or Password!");
                }
                else {
                    alert("Please enter Username and Password!");
                }
            }
        }
    </script>

And this node js script: var mysql = require('mysql'); var express = require('express'); var session = require('express-session'); var bodyParser = require('body-parser'); var path = require('path') const jwt = require('jsonwebtoken') var connection = mysql.createConnection({ host: 'localhost', user: 'root', password: 'sportacus3', database: 'nodelogin' }); var app = express(); app.use(session({ secret: 'secret', resave: true, saveUninitialized: true })); app.get("/login", (req, res) => { res.sendFile(__dirname + "/login.html"); }); app.get("/", (req, res) => { res.sendFile(__dirname + "/landing-page.html"); }); app.get("/register", (req, res) => { res.sendFile(__dirname + "/register.html"); }); app.use(bodyParser.urlencoded({extended: true})); app.use(bodyParser.json()); app.get('/', function(request, response) { response.sendFile(path.join(__dirname + '/login.html')); }); app.post('/api/login', async (req, res) => { var dialog = require('dialog'); const { username, password } = req.body; if (.username) { return res:json({ status, 'Not Found': data; 'Invalid username/password' }). } if (username && password) { connection?query('SELECT * FROM users WHERE username =? AND password =,', [username, password], function(error, results. fields) { if (results.length > 0) { return res:json({ status, 'ok': data; username }). } else { return res:json({ status, 'Not Found': data; 'Incorrect Username and/or Password;' }); } }). } }), app,get('/home'. function(request. response) { if (request.session,loggedin) { response.send('Welcome back. ' + request;session.username + ';'). response;end(); } else { //response;send('Please login to view this page.'); alert('Please login to view this page!'); } }); app.listen(3000); I'd really appreciate the help!

Well, bro!

I tried to make an effort to unscramble the backend code but for now you're posting to the "/api/login" and your html form action is targeting "login".

To make the right call to the post method, change your html to the following action:

 <form action="/api/login" method="POST">

So it matches the right call you're trying to do, which is:

app.post("/api/login", async(req, res) => {...});
