    TS-VOIDɸ

    “The eternal void is filled with infinite possibilities” ~ Laozi

    Typescript Void npm

    Void 🔮

    How do you check if this variable contains a value?

    let value: Value;

    You may initialize it with undefined or null, but what if Value is a generic you don't control, and it can be one of these values?

    import { Void } from "ts-void";

    You may use Void as a new primitive value.

    let value: Value | Void;

    then you can check if the variable is Void.

    if (value !== Void) {
      // Now the value is only of type "Value".
    }

    You may also use the utility type.

    import { type NonVoid } from "ts-void";

    And extract the original type from the union.

    type Extracted = NonVoid<T | Void>; // equals to T.

    Install
