Step by Step Guide to Building a Ghost API Integration in Ruby

Aug 13, 2024 • 5 minute read

Introduction

Hey there, fellow Ruby enthusiast! Ready to dive into the world of Ghost API integration? You're in for a treat. Ghost's API is a powerful tool that can supercharge your content management capabilities. Whether you're building a custom front-end, automating content creation, or just tinkering around, this guide will get you up and running in no time.

Prerequisites

Before we jump in, make sure you've got:

Ruby 2.7+ installed (come on, you knew that already!)
A Ghost API key (grab one from your Ghost admin panel)
The Ghost gem (gem install ghost)

Got all that? Great! Let's get our hands dirty.

Setting up the Ghost Client

First things first, let's initialize our Ghost client:

require 'ghost'

client = Ghost::Client.new(
  url: 'https://your-ghost-blog.com',
  key: 'your-api-key'
)

Easy peasy, right? This little snippet is your gateway to Ghost API goodness.

Basic API Operations

Now for the fun part - let's play with some data!

Fetching Posts

posts = client.posts.list
puts posts.first.title

Creating a Post

new_post = client.posts.create(
  title: 'My Awesome Post',
  html: '<p>Look ma, I'm blogging with code!</p>'
)

Updating a Post

updated_post = client.posts.update(new_post.id, 
  title: 'My Even More Awesome Post'
)

Deleting a Post

client.posts.delete(new_post.id)

Advanced Operations

Ready to level up? Let's tackle some more complex operations.

Working with Tags

tags = client.tags.list
new_tag = client.tags.create(name: 'Ruby Rocks')

Managing Authors

authors = client.authors.list
puts authors.first.name

all_posts = []
page = 1

loop do
  posts = client.posts.list(page: page, limit: 100)
  break if posts.empty?
  all_posts.concat(posts)
  page += 1
end

Error Handling and Best Practices

Let's keep our code robust and resilient, shall we?

begin
  client.posts.create(title: 'Oops')
rescue Ghost::Error => e
  puts "Houston, we have a problem: #{e.message}"
  # Implement retry logic here
end

Pro tip: Always respect rate limits. Your future self will thank you.

Testing the Integration

Testing is not a chore, it's a superpower. Here's a quick RSpec example:

RSpec.describe 'Ghost API Integration' do
  it 'fetches posts successfully' do
    VCR.use_cassette('fetch_posts') do
      posts = client.posts.list
      expect(posts).not_to be_empty
    end
  end
end

Performance Optimization

Want to make your integration sing? Try caching:

cached_posts = Rails.cache.fetch('ghost_posts', expires_in: 1.hour) do
  client.posts.list
end

Webhooks Integration (Optional)

For the overachievers out there, why not set up webhooks?

post '/ghost_webhook' do
  payload = JSON.parse(request.body.read)
  # Handle the webhook event
  status 200
end

Conclusion

And there you have it! You're now armed and dangerous with Ghost API knowledge. Remember, the best way to learn is by doing, so go forth and build something awesome. The Ghost API documentation is your friend if you need more details.

Happy coding, Rubyist!
