Vertex Flow

Vertex Flow is a course that helps you move from using Ruby's built-in tools to understanding how to create your own abstractions and organize large codebases. 🌊
After Pulse Forge, you are already comfortable with blocks, iterators, and collections. Now it's time to explore how Ruby lets you modify the language itself to fit your needs: modules, mixins, basic metaprogramming, and combining them without creating chaos.

What’s included
7 modules with videos, in-depth examples, in-code comments, exercises on creating custom modules, and refactoring real scenarios.
Module 1: Modules as composition tool
module vs class • include vs extend vs prepend • Module.nesting and Module.constants
Module 2: Mixins in action
Creating functional modules • Concerns pattern (like in Rails, but without Rails) • name conflicts and super
Module 3: Singleton methods and metaclass
def self.included(base) • class << self • eigenclass / metaclass basics
Module 4: Metaprogramming入门
define_method • class_eval vs instance_eval • method_missing for simple DSLs
Module 5: Refinement and safe monkey patching
using Refinement • modular method overriding without global changes
Module 6: Code organization in large projects
Autoloading basics • namespace modules • avoiding "god objects" through composition
Module 7: Practical architecture exercises
Building a small micro-framework (e.g. simple router or validator) using modules and metaprogramming

Who this course is for
Suitable if you:

• completed Pulse Forge or have equivalent knowledge
• write code over 500–1000 lines and feel it becomes hard to maintain
• want to understand the "magic" parts of Ruby (include, method_missing, etc.) in practice 🤔

Not suitable if you:

• are not yet confident with blocks and Enumerable
• are looking for ready-made solutions without understanding "how it works under the hood"

What you will study
How to create reusable modules and mixins
The differences between include, extend, prepend and their consequences
How to use metaclass and define_method for dynamic code
What Refinement is and when to apply it
How to organize large project code without global pollution
