Top 11 Ruby On Rails Gems For Web Apps

Ruby on rails is a great framework for developing web apps with influential features and it increases the speed of web app development using an MVC pattern. Ruby on rails is known for its various ready-made solutions that eases rapid software development. Mainly such speed is obtained through using Ruby on rails gems, libraries with explicit functionalities that allows you to prolong and customize your rails application.  There are separate rails gem for every purpose in rails, from authorization and authentication to testing and payment processing. Rubygems.org was the most downloaded gem in 2021 and this gives you the idea of market popularity for ruby on rails. Here we’ll discuss the best ruby on rails gems for 2022. But before digging into it, let’s see how to install gems in ruby?

What Are Rails Gems?

RubyGems is a Ruby package manager which includes a standard format for distinguishing Ruby programs and libraries, a tool for managing gem installation and a server for delivering them. 

Command-line utility controls RubyGems called a gem, that may install and manage libraries. RubyGems works with Ruby run-time loader to locate and laid gems from library directories.

How To Install Gems In Ruby?

1. Install Bundler-

Open terminal and cd to program directory on internet-connected PCs, and type below command-

$gem install bundler

Another way is- once you know which gem you’d like to install, for example, most popular ruby on rails installation

$gem install rails

2. Add Gems To Gemfile-

Find gem file in project’s root folder and add following command-

source ‘https://rubygems.org’
gem ‘[nameofgem]’
gem ‘[nameofgem]’, ‘~>[versionofgem]’
gem ‘[nameofgem]’, :require => ‘[spec]’

3. Installing Required Gem-

Install all the gem required in the gems file using following command:

Most Common Mistakes To Avoid In Ruby On Rails Development

Ruby on Rails is a popular web framework that allows you to build scalable, enterprise-ready applications with complete front-end support. Rails is following the convention over configuration approach and its own set of standard conventions for naming, structure and configurations. Rails is an easy to use development framework but some of it’s projects are tough to manage due to the some wrong approaches that we are using while handling it. So here we’ve listed some common mistakes that Rails developers commit. 

Most common mistakes in ruby on rails development-

1. Not using the correct rails application for your requirement-

Most of the web services apps are still using a traditional Rails web application. Why? What is the reason to use traditional Rials when you have all the latest one’s? New versions of Rails introduced API mode that is completely dedicated to build Rails API. If you don’t know then you can run the following command to create API app, 

rails new [api_name]  --api

It executes the unused and superfluous set of middleware like views, assets and so on. It starts the application with some needed middleware instead of loading unnecessary code libraries. Hence before starting development of your app analyse the purpose of application. If you’re thinking to develop web app then prefer the traditional rails web application. But if you’re building only API then prefer API mode application.

2. Putting too much logic in the controller-

We all know that Rails is based on MVC architecture. Moving view logic or domain/model logic into controller is easy. But the problem is, Controller object will start violating the single responsibility principle that makes future changes to the code base difficult and error-prone. Generally, the only types of logic should be in your controller are:

• Session and cookie handling- This may include authentication/authorization or any extra cookie processing you have to do.
• Request parameter management- Collecting request parameters and calling appropriate model method to persist them.
• Rendering/redirecting- Rendering the result(html, xml, json etc) or redirecting as appropriate.
• Model selection- Logic for finding the right model object given the parameters passed in from the request. Ideally this should be a call to a single find method setting an instance variable to be used later to deliver the response.

This still pushes the limits of single responsibility principle, it’s kind of a bare minimum that the rails framework needs us to have in the controller.

3. Excessive use of RubyGems-

RoR developers are lucky because they get a large number of gems to ease development. But some of the developers make excessive use of gems in their applications to the extent that gems’ use is more than functionality of the app.  The main issue that arises from Gems’ excessive use is that your web app’s size increases and this reduces the app performance. Also, it requires more memory configurations and increased optimization costs. So your rails app takes more time to start that reduces development time. Also with each gem you add, dependency on another gem includes. So you increase the number of dependencies in your app, that creates lags in application. This is called the compounding effect. For instance, using a gem rails_admin creates dependencies for 11 more gems. So you should consider this before you use a gem.

4. Mistakes we commit in Rails ActiveRecord-

ActiveRecord is a great ORM feature in Ruby on Rails that will map database tables and models. It provides lot of methods to carry out database I/O operations. You must focus on future scope and challenges while building app architecture. Most of the developers don’t understand the working of ActiveRecord in rails. This can cause the performance issue in application.

For example, to check the record availability what query you will use? Here most of the developers will prefer to use either one of the options,

Option 1:

User.where(is_active: true).count > 0
=> SELECT COUNT(*) FROM "users" WHERE "users"."is_active" = $1  [["is_active", "t"]]

Option 2:

User.where(is_active: true).any?
=> SELECT  1 AS one FROM "users" WHERE "users"."is_active" = $1 LIMIT $2  [["is_active", "t"], ["LIMIT", 1]]

Which option is best to check record availability? Option 1 or Option 2?  Option 2 is better. Why? There is a reason! Here we’re checking the availability of specific case. So only checking availability is not sufficient. No compelling reason to check the tally and discover the accessibility. So it’s prefer to use right option based on your use case.

5. Blocking on calls to external services-

Third party providers of Ruby on Rails apps eases the APIs integration bust sometimes it may run slow. To avoid blocking on calls, instead of calling services from your Rails app, you should move some part of code to background task. To query these API services, you should use Delayed Job, Sidekiq and so on.

6. Improper predicate method usage-

Predicate method is a method that syntactically ends with question mark and should return a true value. When you create a predicate method, it is necessary to know its main purpose. It should be named for what it performs, it should not contradict the name with the action it performs.

For eg., check  whether the user has books available or not, you should define the predicate method in user model as mentioned below-

def books_available?
    self.books.present?
end

7. Managing database schemas-

Rails supports Active Record migrations to manage all database schema rather than dealing with raw SQL. Migration files are stored with timestamp, it tells which migration file should run first. If you want to add, modify and remove existing schema write a new migration file. Don’t change in the existing file even though it is a small change. Understand the use case for change vs Up down methods better. When you run rollback change method, it will tackle automatic revert so that there is no need to write a separate down method.

class AddImageToUsers < ActiveRecord::Migration
 def change
add_column :languages, :ruby, :string
 end  
end 

Basically, Up down methods supports the custom changes like running SQL.

class AddImageToUsers < ActiveRecord::Migration
 def up
add_column :languages, :ruby, :string
Language.update_all(ruby: 'Rails')
 end
 def down
remove_column :languages, :ruby
 end  
end

Django Vs Ruby on Rails: Which One to Choose? And When?

Selecting the best technology is an important step for web development as it decides how your website and app will perform. There are a lot of web development frameworks and technologies available in the market and hence many entrepreneurs and freelancers get confused to choose the best from a large pool. Most of the entrepreneurs prefer frameworks that are entirely open-source, have wide community support and offer rapid development. Web app development is divided in two parts: front end development and back end development, accordingly there are a lot of tools available to develop robust and scalable web apps.

Django and Ruby on rails are the two most popular web applications that offer development of interactive and scalable websites and web apps. Before proceeding towards Django vs Ruby on rails, let us see each one in detail.

What Is Django?

Django is a Python based web framework released in 2005. It is an open-source and general purpose framework which makes it popular among web developers. This framework was designed to simplify the development of complex and database driven websites. It allows rapid development with neat and pragmatic design.

What Is Ruby on Rails?

Ruby on Rails is a server-side, open source web app framework written under MIT Licence. Rails provides a great default structure for database, pages and web services. It works on DRY(Don’t Repeat Yourself) and Conversion Over Configuration. DRY eliminates the need of doing the same task of coding repeatedly and Conversion Over Configuration means you can adapt instead of creating your own rules every time. And this makes the whole process easy.

Similarities Between Django And Ruby on Rails-

Django and ROR both are used to develop interactive and scalable websites and web apps. Let us see similarities of both frameworks-

• Django and ROR both are open source web app frameworks, used to build robust web apps and websites.
• Both frameworks have a large and active community, so if you have any issue, a large community is there to help you to solve your problem. Hence ROR developers and Django experts are preferring these frameworks
• Both the frameworks are fast, reliable and speed up the development process.
• Django and Ruby on Rails both are MVC based structure means website or web app development will be arranged into layers, models, defined routes and controllers within the framework itself.

Django Vs Ruby on Rails-

1. Maturity Of Platform-

Django was first released in 2005 and since it has been on the list of best frameworks for web development. His recent release was released in December 2019 which includes many new features and improved usability. 

ROR was first released in 2003 and in 2004 it was declared as an open source program. It’s latest version is released in August 2019.

2. Syntax-

ROR is based on ruby while Django uses Python. Python is a widely used programming language and is popular for its simple and readable code whereas Ruby is famous for its syntax. Ruby has a simple syntax like english language and this makes it popular among the developer community.

3. Principles-

Principles holds the process of web app development. Django has to principles  and “Explicit is better than Implicit.” This helps developers to create easy to understand software that can be managed by many people.

Ruby on Rails uses DRY and the Configuration Convention means you have to follow the guidelines so as to be successful instead of making your own configurations. It helps to improve efficiency and speed.

4. User Interface-

Django and ROR both are absolute winners in this case. Both of them offer a high-class experience. These web frameworks allow you to develop fully loaded functional websites with add-ons and plugins.

5. Speed And Performance-

In the comparison of ROR and Django, Rails is 0.7% faster because of its amazing libraries and plugins. All things considered, Django similarly supports rapid development processes and is a great decision for a web framework. Django REST framework delivers convenience as authentication modules, JSON serializers/deserializers etc. When comparing Django vs ROR, Django may have an edge because REST is and advantage of Django. The performance of Django vs Rails is high for both as it uses modern programming languages while providing tools to optimize the code.

6. Security-

Django and ROR, both are secure web app frameworks having set of tools that websites or web apps from SQL injection, cross-site scripting and so on. You can trust both of these frameworks as far as security.

7. HTML Template-

Although the main feature of Django and Ruby on Rails framework is template, Django makes use of simple template language to allow developers for template creation with less programming and HTML capabilities. On the other side, Rails’ views are more complicated.

8. Web Servers-

Main web servers for Django are NGINX using WSGI, Apache, Gunicorn and Cherokee, whereas database servers for Django are SQLite, PostgreSQL, MySQL and Oracle.

Ruby on Rails web framework uses NGINX, Apache and WEBrick as prominent servers. Database servers for Rails include MySQL and PostgreSQL.

9. Community Support-

Django is an open source framework and has an open source ecosystem, which means there are a bunch of libraries and tools available which are free and paid. It has documentation which is enough to provide you a solution for issue. Django community is more than 11000 with more than 4000 ready packages for developers.

Ruby on Rails has an active community of 5000 people who have already contributed with reusable code.

When To Choose Django?

• If you require configuration-based approach 
• If you do not need out of the box functionality
• You can choose Django if your team is ready to use Python 

When To Choose RoR?

• If you have a skilled team of developers 
• you need to develop application fast with libraries
• should be able to iterate quick RoR minimizes code writing time and lets your team deploy faster.

Final Words-

Selecting the right framework is an important task. Django and Ruby on Rails are great frameworks having their own advantages and disadvantages. Considering above factors will surely help you to decide the best one according to project’s requirements.

You can hire dedicated Django developers of solace team, if you want to use a Python-based framework. Also if you want more functionalities for your web app, then you can go with ROR and hire ruby on rails developers.

PHP vs Ruby On Rails: Which one to choose?

With regards to web development there were two technologies that had transferred static web pages in HTML to the interactive multimedia tech of today. First one is JavaScript, enabling the user to polish a frontend of the solution. The second one is the PHP, that stands somewhere in the middle of the frontend and the backend, standing behind the power of most popular solutions including WordPress and Magento.

But, is one one of the most famous technologies still relevant in 2020? Would it be able to stand comparison with modern languages and frameworks like Ruby on Rails?

What is PHP?

PHP is a script language designed to deliver sites and also web applications in real time. It is one of the most renowned technologies in the web, used by 79% of all websites existing. PHP powers up well known open source solutions with WordPress and Magento being among the most popular ones. Facebook was initially delivered in PHP and later on translated C++. 

What is Ruby on Rails?

Ruby on Rails is a framework for Ruby language intended to make coding simpler, faster and also more convenient for web developers. The technology imposes various good practices including DRY (Don’t Repeat Yourself) that encourages developers to reuse blocks of code. Also, the tool follows the Convention over Configuration path, allowing developers to minimize the configuration work by proposing a predefined environment.

Ruby on Rails is one of the most popular technologies in the world, powering more than a large number of websites out there. It was included in the list of 20 most popular technologies in the world delivered by TIOBE Index and positioned 13th on StackOverflow’s ranking of the most well known programming languages.

Everything You Should Know About Ruby on Rails

Regardless of whether you’re new to coding or you’re as of now active in web development, Ruby on Rails can be a fleeting point. It’s frequently mentioned as coding languages like HTML, CSS, and JavaScript, however when you go deeper further you’ll discover it is not a programming language by any means. So as to understand what it really is. The thing that recognizes it from other coding skills, and how to approach learning it.

What is Ruby on Rails?

Ruby on Rails (or Rails) is a web development framework that gives Rails developers an efficient technique for writing code. Rails is a web framework in the application programming and web development. These frameworks are collection of code libraries. It gives application and web developers readymade solutions for repetitive tasks like building menus, tables, or forms on a site. In other words, instead of writing each line of code in a program without any preparation, web developers can allude to a framework and discover code for basic functions that they can connect to the websites or web applications they’re building.

Web frameworks are generally specific to a certain programming language, and the Rails framework, Sokolyk says, is just a web framework composed over the Ruby programming language. While all frameworks by their tendency to help to make the development of complex websites more manageable. As it were, not only does the Rails web framework cut down on the time sink of re-coding monotonous tasks, however—by utilizing Rails code—Rails developers keep their general work cleaner, less inclined to bugs, and simpler to troubleshoot when issues do occur. 

Simultaneously, Rails subscribes to a general strategy for best practices for Rails developers that evacuates the need to abandon guidelines and rationale for your coding decisions in the code you write—rather, Rails developers work from the mutual shared ground of Rails conventions. Rails is most usually used to build full web applications and APIs (frameworks of tools and resources that are then utilized by developers to make software applications). Due to this, tech jobs that emphasis on giving browser based applications or APIs are probably going to utilize Rails and hire developers with Rails experience. As of this composition—Glassdoor records about 6,000 open jobs for Ruby on Rails Developers.

Ruby for beginners-

While HTML and CSS (markup languages used to characterize the parts of website pages and to change colors, textual styles, and so on.) are frequently indicated as gateways for turning into a web developer, where does that leave web frameworks like Rails? Is Rails something to handle simply after you’re deep in the throes of tech skills, or is it something that is in reach for a beginning web developer, as well?

Rails is actually very beginner friendly. Rails is a very suitable framework to learn as an entry into programming. In any case, to discuss Rails and its significance for beginners, it’s important to come back and comprehend that it’s the Rails framework that is beginner friendly, however the Ruby language it’s based on also.  Rails will include learning probably a few parts of the Ruby programming language—however nothing beyond basic concepts and syntax. “Ruby is a scripting language that has a larger number of applications than utilizing it through Rails,”.

Ruby developers can utilize it to write a script that moves all your music files that have the name of your preferred band into a folder with that band’s name. The Ruby language itself—and not simply the Rails web framework—is a solid choice as a beginning coding language. It’s easy to read and does a great deal of the work for you. Different languages, like C, require more code to accomplish something you can accomplish in a couple of lines with Ruby”. More complicated programming languages eventually offer more options and control—it works out well for somebody simply beginning with web development. Ruby is more than capable for helping you through to the middle of the level of programming. Rails is like an extension of Ruby—once you’ve learned Ruby basics you can start to learn Ruby on Rails.

Pros of Ruby on Rails-

1. Tooling -

Rails gives fabulous tooling that encourages you to deliver more features in less time. It gives a standard structure for web applications, where all the basic patterns are dealt with for you.

2. Code Quality -

For the most part, we find the quality of outsider Ruby code to be altogether higher than their PHP or NodeJS equivalents.

3. Test Automation -

The Ruby community is huge into testing and test automation. We accept this is amazingly important in helping great quality software and is one reason the Ruby libraries are so great.

4. Large Community -

Practically every significant city on the planet has a Ruby people group that runs standard meetups.

5. Popularity -

History has shown that technology that has been popular inside Silicon Valley has bit by bit been received over the world. If you take a gander at the enormous startup successes of recent years, for example, Airbnb, Etsy, GitHub and Shopify — they are all on Ruby on Rails.

6. Productivity -

Ruby is an expressive and compact language, which when combined with the plenty of outsider libraries, empowers you to development features unbelievably quick. I would say it’s the most beneficial programming language around.

7. Next Generation -

Ruby on Rails is the language of choice for some of the prominent online code schools, for example, Makers Academy, Steer and CodeCademy. This should mean an expansion in talented programmers joining the Ruby community over the coming years.

Cons of using Ruby-

1. Runtime Speed -

The most referred to contention against Ruby on Rails is that it’s “slow”. We would concur, positively when compared with the runtime speed of NodeJS or GoLang. The performance of a Ruby application is inconceivably unlikely to be a bottleneck for a business. In 99% of cases, the bottleneck will be somewhere else, such as, inside the development team, IO, database or server designetc. At the point when you get to a significant enough scale to have to worry about Rails runtime speed, then you’re probably going to have an extraordinarily effective application (think Twitter volume) and will have many scaling issues to manage.

2. Boot Speed -

The principle dissatisfaction we get notified from developers working in Rails is the boot speed of the Rails framework. Contingent upon the quantity of gem dependencies and files, it can take a lot of time to begin, which can ruin developer performance. In ongoing versions of Rails this has been to some degree combatted by the introduction of Spring, however we feel this could at present be quicker.

3. Documentation -

It very well may be elusive great documentation. Especially for the less well known gems and for libraries which utilize mixins (which is the greater part of Rails). You’ll frequently wind up finding the test suite acts as documentation and you’ll depend on this to understand behavior. This isn’t itself an awful thing. As the test suite ought to be the most up to date portrayal of the system, but, it can still be disappointing plunging into code when once written documentation would have been much quicker.

4. Multi-Threading -

Rails supports multi-threading, however some of the IO libraries don’t, as they keep hold of the GIL (Global Interpreter Lock). This means if you’re not cautious, requests will get lined up behind the active request and can introduce execution issues. In practice, this isn’t an over the top issue as. If you utilize a library that depends on GLI, you can change to multi-process setup.
