Type regression between v0.31.2 and v0.40.1

[Bluzzi]

Welcome to the issues section if it's your first time!

Before creating an issue, please be sure to:

• Checkout to the latest version, including submodules
• Try to find an isolated way to reproduce the behavior
• Fill in all the blanks in the most specific way you can

Steps to reproduce

import type { Options } from "argon2";

export const options: Options = {
  hashLength: 32,
  saltLength: 16, // <--- Object literal may only specify known properties, and 'saltLength' does not exist in type 'Options'.ts(2353)
  timeCost: 3,
  parallelism: 2
};

Expected behaviour

The “saltLength” field must be present in the Options type, as it was in version 0.31.2 (see the argon2.d.ts file).

Actual behaviour

The “saltLength” field is not present in the Options type, see the argon2.d.cts file in version 0.40.1.

There are other differences between the two versions:

• saltLength no longer exists (original issue)
• the type of salt is any | undefined instead of Buffer | undefined
• the type of associatedData is any | undefined instead of Buffer | undefined
• the type of secret is any | undefined instead of Buffer | undefined
• raw is no longer present - but I see that it is added dynamically when typing the function hash

// v0.40.1
export type Options = {
    hashLength?: number | undefined;
    timeCost?: number | undefined;
    memoryCost?: number | undefined;
    parallelism?: number | undefined;
    type?: 0 | 2 | 1 | undefined;
    version?: number | undefined;
    salt?: any;
    associatedData?: any;
    secret?: any;
};

// v0.31.2
export interface Options {
  hashLength?: number;
  timeCost?: number;
  memoryCost?: number;
  parallelism?: number;
  type?: typeof argon2d | typeof argon2i | typeof argon2id;
  version?: number;
  salt?: Buffer;
  saltLength?: number;
  raw?: boolean;
  secret?: Buffer;
  associatedData?: Buffer;
}

No one has said anything?. They just changed the parameters without changing the doc?

The parameter was not changed, there is a bug in Typescript when generating object types from JSDoc that I still didn't figure out how to fix, since it works as expected on my machine, in an isolated container

[ranisalt]

I just republished and Typescript is still generating incorrect types.

This remains an issue and is blocking us from upgrading from 0.31.2 to the latest version.

Tested with 0.40.3

Is there anything we can do to help with this?

[ranisalt]

v0.41.1 was published with proper types! The culprit was missing install before generating the types, which was causing @types/node to be missing - Typescript does not know what a Buffer is without it, so it output any
