/*
  Incredibly simple Node.js and Express application server for serving static assets.
  
  DON'T USE THIS IN PRODUCTION!
    It is meant for learning purposes only. This server is not optimized for performance, 
    and is missing key features such as error pages, compression, and caching.
  
  For production, I recommend using an application framework that supports server-side rendering, 
    such as Next.js. https://nextjs.org

Webpage Snapshot Bookmarklet

This is a simple bookmarklet that captures any webpage and save as png image using HTML5 technologies. Under the hood it uses HTML2Canvas to capture the webpage to canvas, then we convert the content inside this canvas element to image file.

You may copy the text below and save as bookmark. `javascript:!function()%7Bfunction%20e()%7Bthis&&this.parentNode&&this.parentNode.removeChild(this),html2canvas(document.body).then(function(e)%7Breturn%20new%20Promise(function(t)%7Be.toBlob(t)%7D)%7D).then(function(e)%7Bvar%20t=document.createElement(%22a%22);return%20t.href=URL.createObjectURL(e),t.download=document.title.replace(/%5B/%5C%7C%5C%5C%60~!@#%5C$%25%5C%5E&%5C*%5C+%5C-='%22%5C,%5C.:;%5D+/g,%22%22)+%22_%22+(new%20Date).getTime()+%22.png%22,t.click(),new%20Promise(function(e)%7BsetTimeout(10,e,t)%7D)%7D).then(function(e)%7B0===e.href.indexOf(%22blob:%22)&&(URL.revokeObjectURL(e.href),e.href=%22###%22)%7D).catch(function(e)%7Bconsole.error(e)

Group Array of JavaScript Objects by Key or Property Value

Implementation

const groupBy = key => array =>
  array.reduce((objectsByKeyValue, obj) => {
    const value = obj[key];
    objectsByKeyValue[value] = (objectsByKeyValue[value] || []).concat(obj);
    return objectsByKeyValue;

Download File from URL

Proof-of-concept to download a file from a URL and save it locally. For example, I may wish to retrieve a JAR file from Nexus.

Uses the http package, which does the basics with raw HTTP protocol support.

Possible update: use request, it is like the Python's requests library. There is a companion package called node-request-progress that tracks download progress. See request-progress on GitHub.

Note: The request package has been deprecated.
