We look at using the built in SimpleDelegator class to easily create decorators for objects.
When you receive a JSON response from an API endpoint, it's really easy to convert this to a Ruby hash. But hashes don't feel very Ruby-ish when you're working with them and you can't add methods and treat them like objects.
The core of an API wrapper Rubygem is defining the Resource endpoints so developers can make requests cleanly. We'll also learn how to handle pagination for endpoints that return a list of results.
The core of any API wrapper is the actions for create, read, update, and delete. We'll implement the CRUD for a resource so you can see how to do it and wire up everything together that we've built so far.
How do we test API requests in a Rubygem to make sure that we're integrating correctly with our backend? We'll learn how to use stubs to fake out the request and test our code without any network requests.
In this lesson, we will be learning how to use strace to watch our system calls which we can then use to help debug issues further.
In this episode, we will look at Ruby's Data class which provides a way to define simple classes for value-alike objects.
In this lesson, we will look at the Module#module_function method in Ruby which allows you to call methods defined in a module with the module as a receiver.

In this lesson, we will learn how to leverage built in IRB and Debug commands from Ruby to trace what happens when you run rails console from start to finish.
Whisper.cpp is an open source C/C++ port of OpenAI Whisper that we can use with Ruby for transcribing our videos. We'll also look at how ActiveStorage runs executables like ffmpeg to see how it works behind the scenes just like with what we're building.
In this lesson, we'll create a job to download a video, extract the audio with ffmpeg, transcribe the video with Whisper, and upload the captions to our hosting provider.
Mocks are a handy tool for writing tests in Ruby. You can use them to fake an object and verify that the correct methods were called against it. Perfect for testing a method that integrates closely with another class or module.
