Description

Simplified the creation of pipeable classes with Pipeable.Class() mixin

class MyClass extends Pipeable.Class() {
  constructor(public a: number) {
    super()
  }
  methodA() {
    return this.a
  }
}
console.log(new MyClass(2).pipe((x) => x.methodA())) // 2

class A {
  constructor(public a: number) {}
  methodA() {
    return this.a
  }
}
class B extends Pipeable.Class(A) {
  constructor(private b: string) {
    super(b.length)
  }
  methodB() {
    return [this.b, this.methodA()]
  }
}
console.log(new B("pipe").pipe((x) => x.methodA())) // ['pipe', 4]

Looks like this example was intending to show x.methodB()

Yes) Fixed

[mikearnaldi]

We could make Pipeable.Class() and Pipeable.Class(Base) instead of two

Hi @tim-smart — could you, please, take a look at this when you have a moment?
This feature will make it easier to create pipeable classes in userland code.
