January 19, 2016 — JavaScript developers faced a great revolution with Node.js, by allowing them to write code that runs directly on their machines. They started to easily write tools for the command line that automate a lot of things in their development cycles. npm, which is bundled with Node.js, made this even easier by giving them quick and easy access to tools that others have created, which they install on their machines to access from wherever they are in their system. Make the most out of it Installing packages from npm globally. Read more…

December 28, 2015 — In this article, Ilya Zayats will show you that, from React’s perspective, there is no difference at all in what to render. React helps to organize an application into small, human-digestible chunks. You can avoid any complex internal interactions between small components, while your application continues to be blazingly fast due to the DOM-diffing that React does under the hood. Trying to grasp what’s wrong with a graph or visualization just by looking at SVG generator templates is often overwhelming, and attempts to maintain internal structure or separation of concerns are often complex and tedious. So, can we apply the same techniques to web graphics — SVG in particular? Yes! Read more…

It is not a perfect or complete solution, but it testifies to the notion that performant, robust and indexable single-page applications are achievable: You can embrace web standards while reaping the benefits of sharing data and functionality between different interface screens on a single web page.
