JS server

After run npm init -y code and genared ./package.json You can put start and build at script in jason leaf. path './package.json'

  "scripts": {
    "start": "npm run build && node server.js",
    "build":"v -b js_browser cube.js.v"
  },

here is the pure javascript server code path './server.js'

const http = require("http");
const fs = require("fs");
var path = require('path');

const host = "localhost";
const port = 3000;

const reqListener = function (req, res) {
    console.log('[route] - ', req.url);

    var filePath = '.' + req.url;
    if (filePath == './') {
        filePath = './index.html';
    }

    var extname = String(path.extname(filePath)).toLowerCase();
    var mimeTypes = {
        '.html': 'text/html',
        '.js': 'text/javascript',
        '.css': 'text/css',
        '.json': 'application/json',
        '.png': 'image/png',

        '.otf': 'application/font-otf',
        '.wasm': 'application/wasm'
    };

    var contentType = mimeTypes[extname] || 'application/octet-stream';

    fs.readFile(filePath, function(error, content) {
        if (error) {
            if(error.code == 'ENOENT') {
                fs.readFile('./404.html', function(error, content) {
                    res.writeHead(404, { 'Content-Type': 'text/html' });
                    res.end(content, 'utf-8');
                });
            }
            else {
                res.writeHead(500);
                res.end('Sorry, check with the site admin for error: '+error.code+' ..\n');
            }
        }
        else {
            res.writeHead(200, { 'Content-Type': contentType });
            res.end(content, 'utf-8');
        }
    });
};

const server = http.createServer(reqListener);
server.listen(port, host, () => {
  console.log(`Server is running on http://${host}:${port}`);
});
