Tips for maintaining type information while setting values in a class membership declaration

In my current class implementation, I have defined the following:

export class HavenHandler implements IHavenHandler {


  opts: {
    auto: true
    handleGlobalErrors: true;
    revealStackTraces: true
  }

 // compared to:

  opts: {
    auto: boolean
    handleGlobalErrors: boolean;
    revealStackTraces: boolean
  }


}

I am looking for a way to achieve this functionality:

 opts: {
    auto: true as boolean
    handleGlobalErrors: true as boolean;
    revealStackTraces: true as boolean
  }

This would allow me to easily toggle them to false when required later on. However, currently, I am unable to modify them to false due to restrictions imposed by the compiler.

Answer №1

To specify the type of a property and assign a default value, you can use the following syntax:

class HavenHandler {
  opts: {
    auto: boolean;
    handleGlobalErrors: boolean;
    revealStackTraces: boolean
  } = {
    auto: true,
    handleGlobalErrors: true,
    revealStackTraces: true
  }
}

This approach allows for easy manipulation of boolean values.
