Sidekiq and Redis: Optimize Your Ruby on Rails Application

Learn how to optimize the performance of your Ruby on Rails application! Our blog post guides you through integrating Sidekiq and Redis for efficient background job processing.

In web development, it’s often necessary to perform tasks in the background to improve an application’s performance. Such tasks could include data processing, sending mass emails, or interacting with external APIs. In Ruby on Rails applications, these tasks can be executed asynchronously using background jobs. A popular way to achieve this is by using Sidekiq, a background job framework that relies on Redis, a flexible and powerful in-memory key-value store.

Introduction to Sidekiq and Redis

Sidekiq is one of the most widely used frameworks for background jobs in Ruby on Rails applications. It uses Redis as a job management store to handle thousands of jobs per second. Redis is known for its flexibility and speed, providing an optimal foundation for background job processing.

In this tutorial, we’ll show you how to add Redis and Sidekiq to your existing Ruby on Rails application. You will create a series of Sidekiq worker classes and methods to handle two tasks: uploading data about endangered sharks from a CSV file and subsequently deleting this data.

Requirements

To follow this tutorial, you’ll need:

  • A local machine or development server with Ubuntu 18.04.
  • Node.js and npm installed.
  • The Yarn package manager installed.
  • Ruby, rbenv, and Rails installed.
  • SQLite and Redis installed.

Step 1: Clone the Project and Install Dependencies

The first step is to clone the project and install the required dependencies. The project we’ll be using is an existing Rails project with Bootstrap.


git clone https://github.com/do-community/rails-bootstrap.git rails-sidekiq
cd rails-sidekiq

Then, we install the gems and Yarn dependencies:


nano Gemfile # Add Sidekiq gem
bundle install
yarn install
rails db:migrate

Step 2: Generate a Controller for Endangered Shark Resources

Next, we generate a controller and model for the endangered shark resources:


rails generate model Endangered name:string iucn:string
rails generate controller endangered index

We add methods for data upload and deletion and define routes.

Step 3: Define Sidekiq Workers

We create worker classes to handle data upload and deletion.

Step 4: Add Layouts and View Templates

We create layouts and view templates for our application.

Step 5: Start Sidekiq and Test the Application

Finally, we start Sidekiq and test the application’s functionality.

Conclusion

By integrating Sidekiq and Redis into your Ruby on Rails application, you can significantly improve its performance by offloading time-intensive tasks to the background. This tutorial provides a solid foundation to integrate Sidekiq into your own projects and make your application more efficient.
