Breakpoint.js - скрипт определяет ширину экрана и выполняет действие

---

Пример использования

import breakpoint from './modules/breakpoint.js';

let config = {
  // media query
  // type: string
  // required
  query: '(min-width: 1024px)',

  // callback to call when the query result is true
  // type: function
  // required
  success: () => console.log('Window width is above 1024px'),

  // function to call when the query result is false
  // type: function
  // optional
  fail: () => console.log('Window width is below 1024px')},

  // context to set on success and fail callbacks
  // type: object
  // default: null
  // optional
  context: window
};

// breakpoint will be automatically listening for changes
let destroyBreakpoint = breakpoint(config);

// if you need to stop listening for changes,
// just call the assigned variable
destroyBreakpoint();

$gpg = new GPG();

// create an instance of a GPG public key object based on ASCII key
$pub_key = new GPG_Public_Key($public_key_ascii);

// using the key, encrypt your plain text using the public key
$encrypted = $gpg->encrypt($pub_key,$plain_text_string);
