Hey there, fellow developer! Ready to supercharge your CI/CD workflow with Circle API? You're in the right place. We're going to walk through building a Circle API integration using Ruby, and trust me, it's easier than you might think. We'll be using the circleci
gem, which is going to make our lives a whole lot easier.
Before we dive in, make sure you've got:
First things first, let's add the circleci
gem to your project. Pop this into your Gemfile:
gem 'circleci'
Then run:
bundle install
Easy peasy, right?
Now, let's get that CircleCI client set up. It's just a couple of lines:
require 'circleci' CircleCi.configure do |config| config.token = 'YOUR_CIRCLECI_API_TOKEN' end
Replace 'YOUR_CIRCLECI_API_TOKEN'
with your actual token, and you're good to go!
Let's start with some basic calls to get our feet wet.
user = CircleCi::User.me puts user.body
projects = CircleCi::Project.all projects.each do |project| puts project['reponame'] end
See? Nothing to it!
Now let's get into the meat of it - working with builds.
build = CircleCi::Project.build('username', 'project', 'branch') puts "Build started: #{build['build_url']}"
build_info = CircleCi::Build.get('username', 'project', 'build_num') puts build_info['status']
result = CircleCi::Build.cancel('username', 'project', 'build_num') puts "Build cancelled: #{result['status'] == 'canceled'}"
Workflows are a big part of CircleCI. Here's how to interact with them:
workflows = CircleCi::Workflow.all('username', 'project') workflows.each do |workflow| puts workflow['id'] end
workflow = CircleCi::Workflow.get('workflow_id') puts workflow['status']
Artifacts are the bread and butter of CI/CD. Let's see how to handle them:
artifacts = CircleCi::Build.artifacts('username', 'project', 'build_num') artifacts.each do |artifact| puts artifact['path'] end
CircleCi::Build.artifacts('username', 'project', 'build_num').each do |artifact| `wget #{artifact['url']}` end
Now that you've got the basics down, let's look at some advanced techniques.
The CircleCI API uses pagination for large result sets. Here's how to handle it:
page = 1 loop do builds = CircleCi::Project.recent_builds('username', 'project', page: page) break if builds.empty? builds.each { |build| puts build['build_num'] } page += 1 end
Always be prepared for things to go wrong:
begin CircleCi::Project.build('username', 'nonexistent-project', 'branch') rescue CircleCi::Error => e puts "Oops! Something went wrong: #{e.message}" end
Be mindful of rate limits. The circleci
gem handles this automatically, but you can check the limits:
response = CircleCi::Project.all puts "Rate Limit: #{response.headers['X-RateLimit-Limit']}" puts "Remaining: #{response.headers['X-RateLimit-Remaining']}"
Don't forget to test! Here's a quick RSpec example:
RSpec.describe 'CircleCI Integration' do it 'fetches user information' do user = CircleCi::User.me expect(user.success?).to be true expect(user.body).to include('login') end end
A few tips to keep in mind:
And there you have it! You're now equipped to integrate CircleCI into your Ruby projects like a pro. Remember, the CircleCI API is powerful and flexible, so don't be afraid to explore and experiment. Happy coding, and may your builds always be green!

gem documentation.
