### JS server
Afer run `npm init -y` code and genared `./package.json`
You can put `start` and `build` at script in jason leaf.
`path './package.json'`
```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'`
```javascript
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',
'.jpg': 'image/jpg',
'.gif': 'image/gif',
'.svg': 'image/svg+xml',
'.wav': 'audio/wav',
'.mp4': 'video/mp4',
'.woff': 'application/font-woff',
'.ttf': 'application/font-ttf',
'.eot': 'application/vnd.ms-fontobject',
'.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}`);
});
