How do I implement basic authentication in my app?

To implement basic authentication, you need to set up a login form and validate user credentials on the server.

What technologies can I use for the server-side implementation?

You can use Node.js with Express, Python with Flask, or any server-side language that supports HTTP.

Can you provide a code example for Node.js?

Sure! Here's a simple example using Express:

const express = require('express');
const app = express();
const basicAuth = require('express-basic-auth');

app.use(basicAuth({
    users: { 'admin': 'password' },
    challenge: true,
}));

app.get('/', (req, res) => {
    res.send('Hello, authenticated user!');
});

app.listen(3000, () => {
    console.log('Server running on port 3000');
});

What are the security implications of using basic auth?

Basic auth sends credentials in an encoded format, so it's important to use HTTPS to encrypt the data during transmission.
