class mime sample. add type in need

mime.js

const mime = {
  getType: function (el) {
    let t = el.split('.')[1];
    this.type = {
      json: 'application/json',
      ico: 'image/x-icon',

      css: 'text/css',
      html: 'text/html',
    };
    return this.type[t];
  },
};
export { mime };

/*
For using

const mime = require('./mime.js');
or
import { mime } from './mime.js';


mime.getType(filename)

// ex : mime.getType('index.html');
// result : 'text/html'


PS: handle filename if more then one '/' in pathname.

let url = new URL(request.url);
let u = url.pathname;
let t = u.split('.');
filename = t[0].split('/')[(t[0].split('/')).length - 1] + '.' + t[1]; // result as 'index.html'
