Serve static files dynamically with Python3

smartserve.md

python3 -m http.server is stupid so just pip3 install livereload and then run this:

# smartserve.py
from livereload import Server
from http.server import SimpleHTTPRequestHandler
import os

class NoCacheRequestHandler(SimpleHTTPRequestHandler):
    def end_headers(self):
        self.send_header("Cache-Control", "no-store, no-cache, must-revalidate, max-age=0")
        self.send_header("Pragma", "no-cache")
        self.send_header("Expires", "0")
        super().end_headers()

    def send_error(self, code, message=None):
        if code == 404:
            self.path = "/index.html"
            return self.do_GET()
        super().send_error(code, message)

server = Server()
server.watch(".", delay=0.2)
server.serve(
    host="127.0.0.1",
    port=8000,
    root=".",
    handler_class=NoCacheRequestHandler
)
