Xxd-log NPM | npm.io

Usage

const log = require("xxd-log");

// Different log levels
// Accept same arguments as `console.log()`
const count = 5;
log.trace("count: %d", count);
log.debug("count:", count);
log.info(`count: ${count}`);
log.warn({ count });
log.error(new Error(`count (${count}) is wrong.`));
log.fatal("Duang!");

// Use chalk directly
console.log(log.chalk.red("This is red."));

Configure

// Change options of the default logger instance.

log.withLabel = false; // Do not display labels before messages.
log.withTimestamp = false; // Do not display current time before messages.
log.highlightStackTrace = false; // Do not highlight key positions in error stack trace.
log.timestampFormat = "HH:mm:ss.SSS"; // Customize the time format.

log.withLabel = log.defaultOptions.withLabel; // reset an option to default value.

// Use an individual instance with different options

const anotherLogger = log.newLogger({
  withLabel: false,
  withTimestamp: false,
  highlightStackTrace: false,
});

You can change these options at any time in the process, and will take effect from next call of logging.

For further instruction of time format, please see moment.js documentation
