Introduction 

Libraries are a developer’s best friend and lifesaver.  Ruby is a well-known general-purpose programming language that is primarily used for web applications with really good Ruby on Rails libraries. It is widely used in web server development, DevOps, data processing, web scraping, and crawling. Ruby on Rails is a server-side web application framework that is used in conjunction with Ruby.

Useful Ruby on Rails Libraries

Here are some of the most important gems found in Ruby libraries. Some of them aid in code debugging, while others provide specific functionality such as authentication. That can be applied to almost any project. Finally, they all help us work faster and produce better software. Here you can explore some of the best Ruby libraries that are useful to build different types of web applications.

1. Devise

One of the Ruby on Rails libraries is Devise. Whether you require simple HTTP authentication or a complex Facebook and Google+ login system, this authentication solution is excellent and will significantly speed up your work. It’s built on the Rails MVC stack, and its modular architecture lets you pick and choose what you need.

2. Asset_sync

This rails library, as the name implies, will assist you in synchronizing assets between Rails and S3. It is intended to work with the brand-new Rails Asset Pipeline feature introduced in Rails 3.1. After running bundle exec rake assets: precompile, your assets will be synchronized to your S3 bucket, with the option to delete unnecessary files and only upload those that are required. On GitHub, it has over 1.9k stars. It is a well-known ruby library that helps in the procedure of code synchronization.

3. Identity_cache

Another in the list of ruby on rails libraries is identity_cache. One of the most effective ways to improve app performance is caching.  This is provided by Shopify. It allows you to specify how your model objects should be cached at the model level and adds a number of convenient methods for accessing those objects through the cache. Memcached serves as the backend cache store, and the database is only accessed if Memcached cannot find a copy of the object. On GitHub, it has over 1.8k stars.

4. Ice_cube

One of the most common tasks of a developer is to handle scheduled events. It is one of the most used ruby frameworks or libraries that are popular among developers. This is a library that makes it simple to handle scheduled events. In a pleasant Ruby syntax, the API is modeled after iCalendar events. The ability to specify multiple rules and have an ice cube quickly figure out whether the schedule falls on a specific date, or what times it occurs, is the power. On GitHub, this library has over 2k stars.

5. Better_errors

Rails libraries include better_errors which is one of the topmost rails libraries. Better Errors is a Rails extension that replaces the standard error page with a much better and more useful error page. It can also be used outside of Rails as Rack middleware in any Rack app.

6. Cancancan

This authorization gem, the successor to the abandoned Cancan project, allows you to define what a user can do on your website by using abilities defined in a single place. Cancancan is the best Ruby on Rails library that is mainly used for authorization and it allows the users to access the data.

7. Delayed_job

This gem is ideal for extracting longer-running actions (such as sending newsletters to a large number of users) into a background task. You can reuse methods from your models or create complex classes to handle all of your background task requirements. Even progress bars are possible in Ruby on Rails with delayed_job.

8. Letter_opener

It’s a pain to set up email delivery in a development environment, which is where Letter Opener comes in handy. It displays the email in your browser, allowing you to easily inspect it, click any links (for example, account confirmation), and avoid spamming your email account with a large number of test emails.

Conclusion:

When developing Ruby on Rails web applications, it is common practice to use Ruby gems. The gems listed above are effective at resolving common issues in Rails applications. Furthermore, the gems eliminate the need for each app to reinvent the wheel. Using these gems frequently isn’t a bad thing, but it’s critical to use them correctly in order to build perfect applications. Gems, on the other hand, will not solve all of your application development issues.

An experienced Ruby on Rails developer will be able to customize the use of an installed Rails gem for your rails application. Tagline Infotech is a hub where you can find cost-effective and wise RoR developers.
