Basic Steps to Add Sidekiq to Rails 7 App

rails_7_using_sidekiq.md

Gemfile

gem "sidekiq", "~> 6.2"
gem "sidekiq-failures"

Update config/application.rb

 class Application < Rails::Application
    config.active_job.queue_adapter = :sidekiq
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 7.0

Update config/puma.rb and config/database.yml respectively:

max_threads_count = ENV.fetch("RAILS_MAX_THREADS") { 10 }

  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 10 } %>

This prevents sidekiq active record ActiveRecord::ConnectionTimeoutError errors.

Update Procfile.dev

Add worker
worker: bundle exec sidekiq

Update config\routes.rb

Require sidekiq before routes.draw and add route for admin user (ignore admin if user table does not have admin column).

require 'sidekiq/web'

Rails.application.routes.draw do
  authenticate :user, lambda { |u| u.admin? } do
    mount Sidekiq::Web => '/sidekiq'
  end
 
  # rest of routes...

Hatchbox

If using hatchbox add new process worker

bundle exec sidekiq
