Universal Testing Pattern

You can use a really simple pattern to enable your browser modules to run in Node.js. Just allow a window object to be passed in to your module and prepend any references to browser globals with win. Set win to the passed in window object if it exists, otherwise fallback to global window.

  import window from 'handle-window-undefined'

  function createTitle(text, win) {
    win = win || (typeof window === 'undefined' ? undefined : window);
  
    const title = win.document.createElement('h1');
    title.innerHTML = text;
    return title;
  };
 
  module.exports = createTitle;
