Step by Step Guide to Building an Adobe Experience Manager API Integration in Ruby

Introduction

Hey there, fellow developer! Ready to dive into the world of Adobe Experience Manager (AEM) API integration with Ruby? You're in for a treat. AEM's API is a powerful tool that lets you interact with content, assets, and more. In this guide, we'll walk through creating a robust integration that'll make your AEM-powered projects sing.

Prerequisites

Before we jump in, let's make sure you've got your ducks in a row:

• A Ruby environment (2.7+ recommended)
• Access to an AEM instance (obviously!)
• Your favorite text editor or IDE

Oh, and don't forget to install these gems:

gem install httparty json

Authentication

First things first – let's get you authenticated. Head over to your AEM instance and grab your API credentials. Got 'em? Great!

Now, let's set up authentication in Ruby:

require 'httparty'
require 'base64'

class AEMClient
  include HTTParty
  base_uri 'https://your-aem-instance.com'

  def initialize(username, password)
    @auth = {
      username: username,
      password: password
    }
  end
end

Basic API Connection

Time to create a client and make sure everything's working:

client = AEMClient.new('your_username', 'your_password')
response = client.get('/api/assets.json', basic_auth: @auth)

puts response.code
puts response.body

If you see a 200 status code, you're golden!

Common API Operations

Let's cover the CRUD operations – the bread and butter of any API integration.

Reading Content

def get_page_content(path)
  get("/api/content#{path}.json", basic_auth: @auth)
end

Creating Content

def create_page(parent_path, name, template)
  post("/api/content#{parent_path}", 
    body: {
      :cmd => 'createPage',
      :parentPath => parent_path,
      :pageName => name,
      :template => template
    },
    basic_auth: @auth
  )
end

Updating Content

def update_page_properties(path, properties)
  post("/api/content#{path}", 
    body: properties,
    basic_auth: @auth
  )
end

Deleting Content

def delete_page(path)
  post("/api/content#{path}", 
    body: { :cmd => 'deletePage' },
    basic_auth: @auth
  )
end

Working with Assets

AEM's asset management is top-notch. Let's harness that power!

Uploading Assets

def upload_asset(file_path, destination_path)
  file = File.new(file_path)
  post("/api/assets#{destination_path}", 
    body: {
      file: file
    },
    basic_auth: @auth
  )
end

Retrieving Asset Metadata

def get_asset_metadata(path)
  get("/api/assets#{path}.json", basic_auth: @auth)
end

Content Manipulation

Want to get fancy with content? Here's how:

Querying Content

def query_content(query)
  get("/bin/querybuilder.json", 
    query: query,
    basic_auth: @auth
  )
end

Error Handling and Logging

Don't let errors catch you off guard. Implement some robust error handling:

def api_request
  yield
rescue HTTParty::Error => e
  logger.error "API request failed: #{e.message}"
  raise
end

Best Practices

• Implement rate limiting to be a good API citizen
• Cache responses when appropriate to reduce API calls
• Always use HTTPS and keep your credentials secure

Testing

Test, test, and test again! Here's a simple RSpec example:

RSpec.describe AEMClient do
  it "successfully authenticates" do
    client = AEMClient.new('username', 'password')
    response = client.get_page_content('/content/mysite')
    expect(response.code).to eq(200)
  end
end

Deployment Considerations

When deploying, remember:

• Use environment variables for sensitive info
• Set up different configurations for staging and production
• Integrate your tests into your CI/CD pipeline

Conclusion

And there you have it! You're now armed with the knowledge to create a robust AEM API integration in Ruby. Remember, the AEM API is vast and powerful – we've just scratched the surface here. Keep exploring, keep coding, and most importantly, have fun with it!
