如何安装node.js从我的家中广播

Question

I am studying Node.js presently and wonder if it is possible to broadcast my sites from one of my home PCs.

For local publishing I am playing with this code:

const http = require('http');
const fs = require('fs');

const hostname = '127.0.0.1';
const port = 3000;

fs.readFile('index.html', (err, html) => {
    if(err){
        throw err;
    };

    const server = http.createServer((req, res) => {
        res.statusCode = 200;
        res.setHeader('Content-type','text/html');
        res.write(html);
        res.end();
    });

    server.listen(port, hostname, () => {
        console.log('Server started on port: '+port);
    });
});

But I am not sure what needs to be done to make my sites available to the public. How do I set up the "hostname" and whatever else needs to be done to broadcast one or more sites.

I am not asking for a complete robust server code, just a minimal site that says Hello on the WEB.

Many thanks

Easy Route: See Arun's answer.

Formal route:

1. Buy a domain name (sounds like you have some)
2. Contact your ISP to get it pointed to a public IP,
3. Get a server to have the public IP
4. Point that server to your local machine's ip:port.
5. If you have node running and listening on that port it should work.

Informal Route: (Skips to step 3 above)

3. Go to your router's configuration page and find the public IP.
4. While at the configuration page set up port forwarding. (This directs traffic to the public ip to your local machine's port that you're listening on.)
5. should be able to access that page via the public IP. (assuming firewalls are set to open those ports too).

Anyone feel free to correct me/add detail to the steps.

Answer 2

you can host it in platforms like Heroku, firebase etc. they give you a url which is publicly accessible.
