La propiedad process.config es una interfaz de programación de aplicaciones incorporada del módulo de proceso que se usa para obtener la representación de JavaScript de las opciones de configuración que se usan para compilar el código node.js actual.
Sintaxis:
process.config
Valor de retorno: esta propiedad devuelve un objeto que contiene la configuración en representación de JavaScript que se utilizan para compilar node.js actualmente ejecutable.
Los siguientes ejemplos ilustran el uso de la propiedad process.config en Node.js:
Ejemplo 1:
javascript
// Node.js program to demonstrate the
// process.config Property
// Include process module
const process = require('process');
// Printing process.config property value
console.log(process.config);
