In common opinion Rails is the perfect framework for fast development, but before making any final judgement you should get familiar with a couple of reasons why Node.js may appear as same beneficial in the context of development speed.
The first and most argument in favour of the statement – Node.js allows programmers the opportunity to write both client-side and server-side. There’s no need to hire specialists for front-end and back-end separately, unlike in Ruby on Rails projects – the two teams are actually merged into one. That fact makes a huge contribution to time efficiency since it allows developers to send and synchronize data between these two sides easily, without wasting time on context change.
Node.js has much better performance than Ruby on Rails
Speed advantages do not limit down to the speed of development. Comparing Node.js with Ruby on Rails in the matter of app performance we don’t give any chance to Rails. Powered by Google’s V8 engine, Node technology demonstrates really impressive running speed. Due to its high performance and scalability opportunities many big companies have decided to switch to Node.js in their products. Some names may appear familiar – Netflix, PayPal, Uber, Medium or Linkedin. Linkedin, a well-known professional social network, has replaced the parts of their Rails back-end with Node.js, what allowed them to increase the performance for some particular scenarios even up to 20 times, using only 3 servers instead of 30.
