No, it won't - the code above sends the same response to all requests.
If you only need a simple REST-like service, this code is enough:
const { app, BrowserWindow } = require('electron')
const PORT = 8080
// electron main
console.log(process.versions);
app.on("ready", function () {
var mainWindow = new BrowserWindow({ show: true });
mainWindow.loadURL("file://" + __static + "/app.html");
mainWindow.webContents.openDevTools()
mainWindow.webContents.once("did-finish-load", function () {
var http = require("http");
var server = http.createServer(function (req, res) {
console.log(req.url)
if (req.url == '/123') {
res.end(`ah, you send 123.`);
} else {
const remoteAddress = res.socket.remoteAddress;
const remotePort = res.socket.remotePort;
res.end(`Your IP address is ${remoteAddress} and your source port is ${remotePort}.`);
}
});
server.listen(PORT);
console.log("http://localhost:"+PORT);
});
});
The contents of app.html could be anything.
Ahahaha. The most funny stuff I've seen in last year. @derekchiang did you hear about the technique of caching objects received with require function into variables?
And did you, @dirkk0 hear about the ability of defining languages to code blocks?
@dirkk0 The version you show completely removes the security features IPC brings to the table.
@draeder Why is that? It is a local server and only handles certain RESTful URLs. Can you explain a little bit?

I believe what he want to say is IPC is not exposed, your API and files can only be loaded from Electron itself, your approach will allow user to say, open Chrome and go to the address directly
@curlyz You are correct. I actually ended up using @dirkk0 's version to embed a Gun DB relay server inside of Electron which needs to be exposed to the local network. It actually turned out to be quite useful.. so Thank you @dirkk0
@draeder you are very welcome. Thanks for letting us know that it works for you!
So Im relatively new to Electron and JS as a whole.
if im understanding this correctly, /foo/bar would be a directory on your webserver. so could i instead say
localhost:8000/index.html/
will that return a different web page?
