I have a very basic setup in my electron.js. then I have a js file that link directly to index.html:

app.js

 const http = require('http');
 var url = require('url');
 var fs = require('fs');
 const hostname = '127.0.0.1';
 const port = 3000;
 http.createServer(function (req, res) 
 var q = url.parse(req.url, true);
 var filename = "example.html";
 fs.readFile(filename, function(err, data) 
 res.writeHead(200, 'Content-Type': 'text/html');
 res.write(data);
 return res.end();
 );
).listen(port, hostname,()=>
 console.log(`Server running at http://$hostname:$port/`);
);

So far I can access to example.html by going to localhost:3000, using the same computer.

But I want to use other device to connect to this example.html. So I thought it should be straight forward. First, I need to find out the local IP:

var os = require('os');
var addresses = ;
for (var k in interfaces) 
 for (var k2 in interfaces[k]) 
 var address = interfaces[k][k2];
 if (address.family === 'IPv4' && !address.internal) 
 addresses.push(address.address);
 
 

console.log(addresses);

I get 192.168.0.200, which is the ip my wifi router provide to my computer. Then, I try access to example.html by browser with URL 192.168.0.200:3000, The browser cannot find the page.

Is there anything missing?

As it turn out, it is rather straight forward.
I just have to replace 127.0.0.1 with whichever IP router provided.

///get the ip from the router
var os = require('os');
var addresses = ;
for (var k in interfaces) 
 for (var k2 in interfaces[k]) 
 var address = interfaces[k][k2];
 if (address.family === 'IPv4' && !address.internal) 
 addresses.push(address.address);
 
 

console.log(addresses);///<-- addresses is an array

 const http = require('http');
 var url = require('url');
 var fs = require('fs');
 const hostname = addresses[0];///<-- first element of addresses
 const port = 3000;
 http.createServer(function (req, res) 
 var q = url.parse(req.url, true);
 var filename = "example.html";
 fs.readFile(filename, function(err, data) 
 res.writeHead(200, 'Content-Type': 'text/html');
 res.write(data);
 return res.end();
 );
).listen(port, hostname,()=>
 console.log(`Server running at http://$hostname:$port/`);
);

then, you can do 192.168.0.200:3000/example.html from any device.
