Things You Must Know on Ruby on Rails Single Page Application
Ruby on Rails is improving and becoming popular amongst many popular technical communities as
well as being implemented by Start-up’s to Giants to build up their applications.
Single page application (SPA) is a website or an application which shows all information in a single
page with dynamic actions, with an objective to provide great user experience to visitors and end
users.
Ruby improves the performance of application by reducing the loading time of HTML, CSS and JS files
and that helps the end users to take more advantage of the app plus allows them to use it to the
fullest.
There is huge demand of SPA and webmasters are moving their sophisticated and complex web
applications from classic web architecture (CWA) to a single-page application (SPA). This will actually
change the way people manage business with these applications.

Let me tell you the key differences between SPA and CWA,
First client request
o CWA: The server returns a full HTML page
o SPA: The server returns a set of templates and data which is then rendered to the
full HTML page, by JavaScript, on the client side.
Subsequent requests
o CWA: The server returns a full HTML page
o SPA: The server returns only the data needed to display the request. Since all
templates are already on the client side from the first request, no HTML/CSS/JS
should be delivered.

Application developer can use various technologies to build SPA but with my experience I will prefer
to go with Ruby on Rails as this is one of the useful frameworks to build single page application.
“Rails can easily serve HTML to web browsers and JSON to API requests from the
same controller action, making it possible to power SPI web apps today right out of
the box. The asset pipeline and Cross-Site Request Forgery (CSRF) handling are a
huge boon to developers that just want to build cool apps without a ton of yak
shaving to get started.”
Pete Forde, Co-Founder of Unspace
At one point of time this questions came to my mind and I am sure it must be coming to you too –
that, “How Rails help to develop and maintain applications, is it easier and robust?”
Well, by the time you reach to the end of this article, this question will be clear and answered.
Before moving your app to SPA you must know about the good and bad part of Ruby on Rails. The
objective of this article is to let you know some of the most important-awesomest features Ruby on
Rails nurses and bad parts while planning to build SPA with Rails.
Ruby on Rails web development framework is built with top Ruby Programming Language and it’s
completely free as Opensource and runs in Linux server.

Lets starts with the Good Part
 The assets in Rails terminology handles static resources and integrates with Webpack.
 Default safe HTTP headers and CSRF protection.
 Default SQL injection protection with bundled ActiveRecord.
 Traditional website optimizations through Turbolinks.
 Default separate configuration for each environment like development, production and
testing.
 Jobs, e-mail integration and integrated database migrations.
 Automatic and high capabilities to code reloading in the development environment.
 Quick booting can be made possible compared to other frameworks.
 Quick and massive community support of your questions.
 Huge numbers of gems are available in community and for all kind of tasks.
 Heavy security with specialized experts, quick solutions of issues and quick new releases
made possible for leaks.
 Quick solution of Github issues.
 Huge numbers of generators, models, controllers including test are available.
 Performance-related data are high in the application's logs.
 highly configurable, easy websockets API through ActionCable and flexible routing made
possible
 bundles with test runners solutions for both Ruby-land tests and full-feature tests through
Capybara (it still lacks an integrated bundled JavaScript test runner though)
Let’s look at the Bad Parts:
 The individual part can't be upgraded by RoR App developers and you will get actionable
support by upgrading the framework.
 It’s very difficult to follow code base at the time of debugging edge cases and the tasks
debugging weird issues estimation also became very hard.
 Lack of active support at the time of implicit auto loading and their problems. Full
action_view is must require even if you only need action_view/helpers/number_helper.
 Automatic or transparent params binding.
 Its slow to boot as compared to other Ruby frameworks, spring is not perfect and shouldn't
be required in the first place.
 At the time of individual test, the test load time increases.

 The API documentation is incomplete and takes more time to look into, exclusively in all
parts of the API.
 Boot process and requests cycle are not clearly understandable.
Winding up…
Ruby on Rails is indeed a great framework to develop any type of web application and SPA. It’s very
important to think how your application is and how that is performing with the end users.
No doubt you can develop single page application with Ruby on Rails in the easiest possible manner.
For a user-friendly Ruby on Rails single page application you need to gather some information like
understanding the database, HTTP verbs and RESTful styles, use of Heroku or Engine Yard.
Do not get bogged down with the bad points listed above – the reason is, it’s very important to know
the weaknesses (and I am sure the updated versions will be removing these loopholes gradually).
So start building wise.
Hope I have shared enough information about Ruby on Rails for single page application
development. Share your thoughts with comments below, if anything I have missed out or if you
think should be part of this article. Will be happy to add in.
