Object-Oriented by Design

ContextJS was built from the ground up with object-oriented programming (OOP) as a core principle—not an afterthought.

Why OOP?

Many modern frameworks rely on function-based patterns and dynamic injection. ContextJS deliberately embraces:

• Encapsulation: Each service is a class with internal state and behavior
• Inheritance: Share logic through abstract base classes
• Polymorphism: Swap implementations via interfaces
• Constructor Injection: All dependencies are passed through constructors, not globals

export abstract class Logger {
  abstract log(message: string): void;
}

export class ConsoleLogger extends Logger {
  log(message: string) {
    console.log(`[log]: ${message}`);
  }
}

Benefits

• Predictability: Class behavior is easy to reason about
• Testability: Mocks and fakes can be injected cleanly
• Maintainability: Code adheres to SOLID principles

Ecosystem Alignment

Every ContextJS package:

• Exposes classes, not loose functions
• Encourages strong typing and inheritance
• Uses object-based APIs for clarity and control
