Creating Simple Login Page with Fastify 2023

Fastify is a web framework for Node.js that allows you to build high-performance web applications quickly and easily. It is designed to be fast, simple, and extensible.

Here is an example of a simple login page built with Fastify:

const fastify = require('fastify')()

fastify.register(require('fastify-formbody'))

fastify.post('/login', (request, reply) => {
  const { username, password } = request.body

  // Validate the username and password against the database

  if (username === 'admin' && password === 'password') {
    // Set the session data and redirect to the dashboard
    request.session.loggedIn = true
    reply.redirect('/dashboard')
  } else {
    // Invalid username or password, redirect back to the login page
    reply.redirect('/login')
  }
})

In this example, the fastify-formbody plugin is used to parse the request body and extract the username and password fields. The user's credentials are then checked against the database, and if they are valid, the user is redirected to the dashboard. Otherwise, they are redirected back to the login page.

Of course, this is just a simple example, and you will likely want to add more features and security measures to your login page, such as password hashing, CSRF protection, and more.
