Creating a new Rails application

To start building a web application with Redis and Ruby on Rails, you need to set up a new Rails application. Rails is a popular web development framework that follows the MVC (Model-View-Controller) architectural pattern and includes many helpful features for quickly building robust web applications. In this article, we will walk through the steps of creating a new Rails application.

Prerequisites

Before proceeding, make sure you have the following installed on your machine:

• Ruby: You can install Ruby using package managers like rbenv or RVM.
• Redis: Redis is an open-source in-memory data structure store, and you need it for integrating Redis with Rails.
• Ruby on Rails: Install Rails by running gem install rails in your terminal.

Step 1: Initializing a new Rails application

To create a new Rails application, open your terminal and navigate to the directory where you want to create the application. Then, run the following command to generate a new Rails application:

rails new myapp

Replace myapp with the desired name for your application.

This command sets up a new Rails application with the default directory structure and installs all the necessary dependencies.

Step 2: Configuring Redis

After generating the Rails application, you need to configure Redis to work with your application.

Open the config/application.rb file in your Rails application directory and add the following line:

config.cache_store = :redis_cache_store, { url: "redis://localhost:6379/0" }

This line tells Rails to use Redis as the cache store for the application.

Step 3: Starting the Rails server

To test your newly created Rails application, start the Rails server by running the following command in your terminal:

rails server

The server should start running on http://localhost:3000.

You can now visit http://localhost:3000 in your web browser, and you should see the default Rails welcome page.

Step 4: Getting started with Redis

To start utilizing Redis in your Rails application, you can begin by installing the redis-rails gem. Open your application's Gemfile and add the following line:

gem 'redis-rails'

Save the file and run bundle install in your terminal to install the gem.

Conclusion

Congratulations! You have successfully created a new Rails application and configured Redis to work with it. You can now start building your web application using the powerful features offered by Rails and the speed and flexibility of Redis.

Remember to explore the official Rails documentation and Redis documentation for more information on utilizing these technologies to their fullest potential. Happy developing!
