Getting started

Follow these steps to get the starter kit up and running on your local machine.

Prerequisites

Make sure you have the following installed:

• Ruby 3.3.x
• Bundler
• Rails 7.0.x
• Git

You will also need an account on Couchbase Capella to create a cluster and obtain the connection details.

Clone the repository

git clone https://github.com/couchbase-conduit-workshop/couchbase-rails-starter.git
cd couchbase-rails-starter

Install dependencies

bundle install

Configure Couchbase Credentials

Copy the .env.sample file in the root directory of the project and rename it to .env. Update the .env file with your Couchbase credentials as follows:

RAILS_COUCHBASE_USERNAME=your_RAILS_COUCHBASE_USERNAME
RAILS_COUCHBASE_PASSWORD=your_RAILS_COUCHBASE_PASSWORD
RAILS_COUCHBASE_CONNECTION_STRING=your_RAILS_COUCHBASE_CONNECTION_STRING_url
COUCHBASE_DEFAULT_BUCKET=your_COUCHBASE_DEFAULT_BUCKET

You can obtain those credentials by first creating an account on Couchbase Capella at https://cloud.couchbase.com/ and then creating a database called rails_starter_app. Inside the database, create a bucket. The name of the bucket is what you should use for the COUCHBASE_DEFAULT_BUCKET environment variable.

Once you have done so, you can navigate to the Connect tab in the database and copy the connection string URL. This is what you should use for the RAILS_COUCHBASE_CONNECTION_STRING environment variable. You will also need to create a user with the appropriate permissions and use the username and password for the RAILS_COUCHBASE_USERNAME and RAILS_COUCHBASE_PASSWORD environment variables.

Running the Test Suite

This application includes the beginnings of a test suite using RSpec. To run the test suite, use the following command:

bundle exec rspec

This will run all the tests and output the results in the terminal. You can run any specific test file by passing the file path as an argument to the rspec command, as follows:

bundle exec rspec spec/config/couchbase_spec.rb

Starting the Application

To start the application, run the following command:

bundle exec rails server

This will start the Rails server, and you can access the application at http://localhost:3000.
