Referencia de la API node:console

require("node:console") y globalThis.console devuelven el mismo objeto. El módulo también exporta Console para escribir en flujos personalizados.

import console, { Console } from "node:console";

console.log("value=%d", 2);
console.table([{ a: 1, b: "x" }]);

const custom = new Console(process.stdout, process.stderr);
custom.warn("written to stderr");

Están disponibles los métodos habituales: log, info, warn, error, debug, dir, trace, table, assert, clear, contadores, grupos y temporizadores. El formato admite %s, %d, %i, %f, %j, %o, %O y %%.

console.table admite arrays y objetos y representa una tabla ASCII. Su espaciado y alineación dependen de la implementación; no analice el texto representado.

Sustituir process.stdout.write o process.stderr.write también intercepta la salida de consola global correspondiente.
