How to run next.js app over https in production mode?

@denis 

To run a Next.js app over HTTPS in production mode, you will need to set up a secure HTTPS server and configure your Next.js app to use it. Here are the steps to accomplish this:

1. Obtain an SSL/TLS certificate: You will need to obtain an SSL/TLS certificate for your domain from a trusted certificate authority. You can purchase a certificate or use a service like Let's Encrypt to obtain a free SSL/TLS certificate.
2. Configure your Next.js app: In your Next.js app, you will need to make changes to the server configuration to enable HTTPS. To do this, you can use the createServer method provided by Next.js to create your own custom server. Here's an example of how you can set up an HTTPS server in your Next.js app:

const fs = require('fs');
const https = require('https');
const next = require('next');

const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev });
const handle = app.getRequestHandler();

app.prepare().then(() => {
  https
    .createServer(
      {
        key: fs.readFileSync('/path/to/private.key'),
        cert: fs.readFileSync('/path/to/certificate.crt'),
      },
      (req, res) => {
        handle(req, res);
      }
    )
    .listen(443, (err) => {
      if (err) throw err;
      console.log('> Ready on https://localhost:443');
    });
});

1. Start your Next.js app: Once you have configured your Next.js app to run over HTTPS, you can start the app by running your custom server file using Node.js. You can run the server file using the following command:

node server.js

Your Next.js app should now be running over HTTPS in production mode. Make sure to configure your server to handle HTTPS requests properly and redirect HTTP requests to HTTPS to ensure a secure connection.
