Shortest functional Web Server Challenge (Any Language)

General
1

What?

Yes, this is a code jam for the shortest (bytes) functional (returns a valid HTTP response when visited by an HTTP-compliant browser) web server challenge.

You might already remember the “Shortest node.js express webserver” topic, and this challenge takes it up a notch by allowing any server-side programming language (available on replit) and any type of webserver.

EDIT: there will be TWO WINNERS: One will be for any server, another for a server which returns the text Hello World!

Comment your submission below!

@python660 what do you mean by shortest? What are we exactly trying to achieve, are we trying to make a website that takes up the least amount of space? I assume HTML wouldn’t count since it isn’t a programming language.

Shortest means smallest program file size (char count, but on a more technical level, byte count), without additional config elsewhere, while being hosted on replit. Yes, HTML doesn’t count bc it isn’t a user-coded web server, and the webserver behind it is probably too long to count.

So PHP or Java or something like that would count? Our goal is just trying to make a website run?

yes, that is indeed correct. you could even try to use esolangs!

On a side note, your website just needs to return a valid HTTP response. Additionally, it needs to be able to be run on a repl.

Node

with(require('express')()){use((q,r)=>r.send('Hello World!'));listen()}

Python

host is only needed to run on Replit, otherwise you can save some bytes

__import__('flask').Flask('').run('0.0.0.0')

a=__import__('flask').Flask('');a.route('/')(lambda:'Hello World!');a.run('0.0.0.0')

That AI looks like it’s trying to lengthen it…

Also, are there gonna be two winners for each programming language or just two winners in general?

I don’t know if this would count, but I ran this in PHP → GET HTTP, and the output console said this →

I believe it is sending an HTTP request (it also says 200, so it is running). Since a Byte is one character my code would only be 8 Bytes.

I don’t really know if this counts as this kind of doesn’t feel like it does :person_shrugging:.

in general, because having winners for a specific programming language can get real boring real fast.

i think that this should end on Jan 1, since that’s Replit’s Death Day.

This is the best I got:

require("express")().use((_,s)=>s.end("Hello World!")).listen()

require("express")().listen()

If im looking at this right, you don’t need the extra pair of parentheses. You do around the arguments, but not the one outer that.

Yes, you’re correct (for some reason the minifier I used at the end added them)

You can put any content in the PHP file and it will serve it. I feel like that falls into

But I’m not sure what really defines a “user coded web server”. Technically all of the express ones aren’t using a user coded server

But running the Repl is really running:

php -S 0.0.0.0:8000 -t

So your language that you’re using to start a webserver is really Bash, not really PHP

Yes, you can because the code is supposed to be what is opening the port. Making a file with a file extension isn’t what opens the port. Which, technically the php command is running some other code, but that’s really what’s being triggered in the beginning.

Okay, using http now and saved a few characters:

require("http").Server((_,s)=>s.end("Hello World!")).listen()
