Custom OTP Behaviors
Understand the structure of OTP behaviors and how to create your own custom generic behaviors to encapsulate common patterns.
Intro: What are OTP Behaviors?
You've learned about OTP behaviors like GenServer and GenStatem. They provide a standard way to build robust, fault-tolerant components.
But what if you have a recurring pattern that isn't perfectly covered by existing behaviors? This is where custom OTP behaviors come in handy!
They let you define your own generic component structure.
Why Custom Behaviors?
Creating custom behaviors offers several key advantages:
- Code Reuse: Encapsulate common logic once and reuse it across many modules.
- Consistency: Ensure all components following your behavior adhere to a specific interface and structure.
- Abstraction: Hide complex internal details, exposing a simpler API to users.
- Maintainability: Changes to the core logic only need to happen in one place.
