How can I avoid mixin issues in TypeScript?

To avoid mixin issues in TypeScript, ensure that your mixins are well-defined and use interfaces to enforce type safety.

What are some common pitfalls when using mixins?

Common pitfalls include type conflicts, improper inheritance, and not using the correct type assertions.

Can you give an example of a mixin implementation?

Sure! Here's a simple example:

class Base { 
  greet() { return 'Hello'; }
}

function Mixin<T extends new (...args: any[]) => {}>(Base: T) {
  return class extends Base {
    farewell() { return 'Goodbye'; }
  };
}

class MyClass extends Mixin(Base) {}
const instance = new MyClass();
console.log(instance.greet()); // Hello
console.log(instance.farewell()); // Goodbye
