Framework, written on Ruby programming language.
Ruby on Rails code example
So, let compare Ruby on Rails vs Node.js.
Accessibility for beginners
A programmer who has learned Ruby "in passing" on a level sufficient for mastering Rails is a rarity. Usually, if someone writes in this language, he studies it purposefully. Ruby, though it has built-in useful methods for dates, strings, arrays and other elements, can still scare away with more complex syntax.
The V8 engine running Node.js shows excellent speed results. Ruby is a slow language, and Rails does nothing to increase productivity, inheriting all the problems of the parent. When developing a small application, it is most likely not affected.
But as soon as there is a certain load on the project, the speed of Node.js will become noticeable. Its non-blocking architecture, built on the use of callback, performs well under concurrency when it is necessary to handle a lot of I / O operations.
For more than ten years, Ruby on Rails framework has managed to develop almost all necessary plug-ins and extensions, which not only simplify the work, but also guarantee the absence of problems with their use. For such a long time, all the critical errors and imperfections of the functional have long been found and corrected.
Node.js is actively developing, and therefore not all libraries and additions have taken their final form and often conflict with each other. Yes, they can be easily installed with the help of a convenient NPM package manager, but, unfortunately, he does not insure against errors.
- Rails immediately uses MVC and offers a set of necessary functions for development. Pure Node.js does not have these advantages, the use of Express.js even though it makes it possible to use the "model-controller-view" model, still does not allow to achieve RoR flexibility. On the other hand, the way to solve a problem in Ruby on Rails is not always obvious and is hidden behind the abundance of gems and magic. Node.js will show exactly what you wrote, with a minimum of distortion.
Technical documentation and community
Ruby - this is a fairly long-established community. Rails is the most popular framework for this language, so it's easy to find information on it. In addition, RoR has a detailed technical background, and gems are usually accompanied by detailed developer and community comments.
Final comparison of Ruby on Rails and Node.js
|Node.js||Ruby on Rails|
|High performance||Lower performance|
|Big selection of libraries, but not all of them are equally reliable and compatible||Many ready-made add-ons with detailed descriptions and comments|
|Using an asynchronous programming language||Using a multithreaded programming language|
|Detailed documentartion on Node.js itself, but less detailed about add-ons||Formed community and documentation around the framework and add-ons to it.|
