I was bored so I wrote a webserver in python, using no external libraries.

from webserver import Webserver, Request, HTMLResponse, html, head, title, link, body, h1, p, div, a

# Start the server on 0.0.0.0 (all interfaces) on port 8080
server = Webserver("0.0.0.0", 8080)
# Set the directory to serve static files from (default is None)
server.static_files_dir = "static"

# Get request to the root path
@server.get("/")
async def index():
    # Return an HTML response
    return HTMLResponse(
        # These functions will directly translate to HTML tags
        # All HTML tags are supported
        html(
            head(
                title("Index"),
                # Link the CSS file from the static directory
                link(attr={"rel": "stylesheet", "href": "/style.css"})
            ),
            body(
                h1("Index"),
                p("This is the index page"),
                div(
                    a("GitHub repo", attr={"href": "https://github.com/alec-jensen/webserver", "target": "_blank"}),
                    a("What's My IP?", attr={"href": "/myip"}),
                    attr={"id": "links"}
                )
            )
        )
    )

# This route shows 2 different things
# - Add the request parameter with the type Request to get the request object
# - Add any other parameters to get the URL query parameters, which are 
#   automatically validated and converted to the correct type
@server.get("/myip")
async def myip(request: Request, format: str):
    if format == "plain":
        return request.client_address[0]
    
    return f"Your IP is: {request.client_address[0]}"

# All types of requests are supported
@server.post("/echo")
async def echo(request: Request):
    return request.body

# Once this is called, the server will start listening for requests
server.start()
