Add function to NodeJs console typescript

I added function red to Node’s console
But how let typescript know it ?

import chalk from "chalk";
const red = (text: unknown[]) =>;
console["red"] = red;

I tried

// console.d.ts
declare namespace NodeJS {
    interface ConsoleConstructor {
        red: (text: unknown[]) => void;

Method 1

You can re-declare the type of console:

declare const console: ConsoleExtension

interface ConsoleExtension extends Console {
  red(text: unknown[]): unknown
