Humble Simple Server - use this to just run index.html without any deps whatsoevvsss.

server.js

const http = require('http');
const fs = require('fs');
const path = require('path');
const mime = require('mime');
const PORT = 8000;

function notFound(_req, res) {
  res.writeHead(404, {'Content-Type': 'text/html'});
  res.end('<p>404 Not Found</p>');
};

function serveFile(_req, res, fileName) {
  let filePath = path.join(__dirname, fileName);
  let mimeType = mime.getType(fileName.split('.').pop());
  let readStream = fs
    .createReadStream(filePath)
    .on('open', () => {
      res.writeHead(200, {'Content-Type': mimeType});
      readStream.pipe(res);
    })
    .on('error', err => {
      res.writeHead(404, {'Content-Type': 'text/plain'});
      res.send(err);
    });
};

http
  .createServer()
  .on('error', error => {
    console.log('error >', error);
  })
  .on('request', (req, res) => {
    let {url} = req;
    switch (url) {
      case '/': {
        serveFile(req, res, 'index.html');
        break;
      }
      default: {
        let extRegex = /[A-Za-z][.]\w+/gi;
        let hasExtension = url.match(extRegex);
        if (hasExtension) {
          serveFile(req, res, url);
