Ruby on Rails, also known as Rails, is a popular open-source web framework that is written in the Ruby programming language. One of the key strengths of Ruby on Rails is its ability to utilize gems, which are small, reusable pieces of code that can be easily added to a project to extend its functionality. In this blog post, we will take a closer look at what Ruby on Rails gems are and their benefits.
What are Ruby on Rails Gems?
Gems are packages of code that can be used to add functionality to a Ruby on Rails application. They are essentially libraries of code that are stored in a central repository called RubyGems.org. Gems can be used to perform a wide variety of tasks, from managing authentication to integrating with external services like social media platforms or payment gateways.
Gems can be installed in a Ruby on Rails application using the gem command in the terminal. For example, to install the popular devise gem, which provides user authentication functionality, you would run the following command: Copy code
gem install devise
Once the gem is installed, you can then add it to your Rails application by adding the following line to your Gemfile:
arduinoCopy code
gem 'devise'
This will make the devise gem available to your Rails application, allowing you to use its functionality.
Benefits of Using Ruby on Rails Gems
There are several benefits to using gems in a Ruby on Rails application. Let’s take a look at some of the most important ones.
1. Time-Saving
One of the biggest benefits of using gems in a Ruby on Rails application is the time it saves developers. Rather than having to write all the code needed to implement a specific functionality from scratch, developers can simply use a gem that already provides that functionality. This can save a significant amount of time and effort, allowing developers to focus on other aspects of the application.
2. Increased Productivity
By using gems, developers can work more efficiently and productively. Rather than having to spend time writing code for every aspect of the application, they can simply use gems to handle the tasks that have already been implemented by other developers. This allows developers to focus on the more challenging aspects of the application, which can lead to a more productive and rewarding development experience.
3. Code Reusability
Gems are designed to be reusable pieces of code that can be used across multiple projects. This means that developers can create gems for commonly-used functionality, such as authentication or file uploading, and then use those gems in multiple projects. This not only saves time, but also ensures consistency and reduces the likelihood of errors.
4. Community Support
The Ruby on Rails community is large and active, and there are many developers creating and maintaining gems. This means that there are likely gems available for almost any functionality that a developer might need. Additionally, many gems are open source, which means that developers can contribute to their development and maintenance, and benefit from the contributions of others.
5. Cost-Effective
Using gems can also be cost-effective for organizations that are developing Ruby on Rails applications. Rather than having to hire developers to write custom code for every aspect of the application, they can use gems to handle many of the common tasks. This can save a significant amount of money and resources, while still allowing the organization to create a high-quality application.
