util.format options need

options to config... Can't change depth now

[lamweili]

@thegobot Would using JSON.stringify(myObject, null, 2) manually suffice?

Using your changes (hard-coded to depth=4)

const myObject = {"a":"a","b":{"c":"c","d":{"e":"e","f":{"g":"g","h":{"i":"i","j":{"k":"k"}}}}}};

const log4js = require("log4js");
const logger = log4js.getLogger();
logger.level = "debug";
logger.debug(myObject);

[2022-01-16T02:30:16.495] [DEBUG] default - {
  a: 'a',
  b: {
    c: 'c',
    d: { e: 'e', f: { g: 'g', h: { i: 'i', j: [Object] } } }
  }
}

Using original code

const myObject = {"a":"a","b":{"c":"c","d":{"e":"e","f":{"g":"g","h":{"i":"i","j":{"k":"k"}}}}}};

const log4js = require("log4js");
const logger = log4js.getLogger();
logger.level = "debug";
logger.debug(myObject);
logger.debug(JSON.stringify(myObject, null, 2));              // manual

const util = require("util");
logger.debug(util.formatWithOptions({ depth: 5 }, myObject)); // manual
