# Gemfile
gem 'redis-rails'

# config/environments/production.rb
config.cache_store = :redis_store, { url: ENV['REDIS_URL'], namespace: 'my_app_cache' }

# Caching a query result
@users = Rails.cache.fetch("users_all", expires_in: 12.hours) { User.all }

# Gemfile
gem 'sidekiq'

# config/sidekiq.yml
:concurrency: 5

# app/jobs/my_job.rb
class MyJob
  include Sidekiq::Worker
  def perform(user_id)
    user = User.find(user_id)
    UserMailer.welcome_email(user).deliver_now
  end
end

# Enqueue a job
MyJob.perform_async(current_user.id)

# Gemfile
gem 'newrelic_rpm'

# config/newrelic.yml
common: &default_settings
  license_key: 'YOUR_NEW_RELIC_LICENSE_KEY'
  app_name: 'My Rails App

# Gemfile
gem 'pghero'

# config/routes.rb
Rails.application.routes.draw do
  mount PgHero::Engine, at: "pghero"
end

# Access PgHero dashboard at /pghero 

 Example:

bundle install

6. Devise for Authentication

Devise is a flexible authentication solution for Rails, allowing you to easily set up user authentication with various configurations and modules.

Example:

# Gemfile
gem 'elasticsearch-rails'
gem 'elasticsearch-model'

# app/models/article.rb
class Article < ApplicationRecord
  include Elasticsearch::Model
  include Elasticsearch::Model::Callbacks
end

# Create the index
Article.__elasticsearch__.create_index!
Article.import

7. RSpec for Testing

RSpec is a testing tool for Ruby, providing a framework for writing and executing test cases, which helps maintain code quality and performance.

Example:

# Gemfile
group :development, :test do
  gem 'rspec-rails'
end

# Install RSpec
rails generate rspec:install

# Example RSpec test
# spec/models/user_spec.rb
require 'rails_helper'
RSpec.describe User, type: :model do

  it "is valid with valid attributes" do
    user = User.new(email: "[email protected]", password: "password")
    expect(user).to be_valid
  end

  it "is not valid without an email" do
    user = User.new(password: "password")
    expect(user).to_not be_valid
  end
end
