Ruby on Rails aKa RoR is a web development framework developed using Ruby’s open source code (licensed by MIT) and object-oriented programming language. It is mainly used to develop database website applications. Rails is a professional development framework that uses MVC (Model-View-Control) mode, built-in support unit testing and integration testing, support for Ajax and RESTful interfaces, ORM mechanisms, and support for the latest industry standards like HTML5., JQuery and more.
It is designed to make web development very easy as long as the developer is familiar with its conventions. Compared to other programming languages and frameworks, Rails allows you to do more with less code and it even makes website development more interesting, hence it becomes the first choice to develop a Minimal Viable Product (MVP) for any start-up .
The Rails philosophy includes the following guidelines:
1. Don’t repeat yourself (DRY: Don’t Repeat Yourself) – writing a duplicate code is a bad thing.
2. Convention over setting (Convention Over the Configuration) – Rails default settings with a variety of good practices, rather than requiring you to set every detail into the profile.
3. REST is the best model for web applications – using Resources and standard HTTP verbs (verbs) to organise your application is the fastest way (we’ll cover this powerful design in the path chapter)
Why choose Rails?
This is an era of development frameworks. Those who are familiar with the development framework can quickly complete tasks and become familiar with the architecture of the website program. It is not too difficult to get started with various programming languages.
Therefore, apart from the preference of programming languages, Ruby on Rails is the most successful and technologically advanced front-end (providing dynamic HTML to browser) application server in the web development framework. Its concept also deeply affects the backward web development framework of many other programming languages, such as ASP.NET MVC, CakePHP, Grails, TurboGears, Pylons, web2py, catalyst, etc. (Imitation is the biggest compliment).
A Ruby on Rails Development Company can develop web applications with very efficient code. In addition, what may surprise you is that it is also the most rich web development framework in the dynamic language, with related books, seminars, consultants, third-party services, plug-ins and so on. Because of the large number of people using Rails, there are people who provide best practices in all directions such as how to write good code, website security, website performance, scalability, full-text search, asynchronous processing, etc. It is a very active community.
Rails is not what
1. As mentioned above, Rails is a development framework for building web applications. If you only need static HTML, you don’t need to use Rails.
2. Rails is not a CMS (Content Management System) content management system. CMS is a set of written station system that allows you to station without having to write a program. Most popular CMS systems on the market are written in PHP, such as Drupal and WordPress. Of course, it is also written in Ruby, such as Radiant. If these station systems just meet your needs, then you don’t necessarily need Rails.
3. Rails is a web development framework that helps you build web applications. It’s not a programming language.
What is Ruby?
Rails is a set of website frameworks developed using Ruby . If you don’t know anything about Ruby and you’re stuck in Rails, it is probably not a good idea.
Ruby is an open source, object-oriented, dynamically interpreted programming language with a simple philosophy, high productivity, ingenuity, and natural grammar. His creator is Matsumoto Hiroshi (also known as Matz ) from Japan . The design was inspired by Lisp, Perl and Smalltalk . The design was designed to allow programmers to write programs happily.
Let’s look at a very simple example:
str = “May Ruby be with you!”
5.times { puts str }
This example simply tells us three things about Ruby:
1. Dynamic typing (typing), no need to declare type
2. Everything is an object, including numbers
3. Use Code Block in the form of anonymous functions (anonymous function) everywhere
We’ll introduce the basic syntax in the Ruby chapter so that readers can get started quickly.
Why choose Ruby?
Ruby is a great emphasis on usability (Usability object) is oriented programming language, a very high value readability and maintainability of code. When designing Ruby, Matz especially considered that it is not easy for people to understand (he said that we are all mortals, like Lisp is for the gods). That’s why you often hear Ruby’s code is naturally simple and beautiful.
Ruby is also the most successful programming language for Domain-specific language (DSL), especially Internal DSL. Through DSL, the program can not only have very good readability, but also greatly increase productivity. Successful DSL libraries include: Rake build tools, RSpec test tools, Chef server setup tools, Cucumber acceptance tests, and more. These libraries are actively affecting our thinking about software development. We believe that there will be more and more interesting DSL libraries.
To Conclude
Of course, one of the most important reasons is the proliferation of productivity after using Ruby on Rails: writing new applications and adding new features becomes much easier. It allows you to do more with less code and the program is easier to maintain. Learning new tools always takes time to invest, and there may be no immediate effect at the outset. But if you have long-term development work and the site has some complexity, then a short-term investment in Ruby on Rails will be well worth it in the long run.
