loglevel-colors

A pre-connfigured instance of loglevel with colors and prefixes

Usage

The default loglevel is DEBUG, but this can be configured either by setting the env var LOGLEVEL, or passing the log level in as a second argument.

The possible log levels are:

• TRACE
• DEBUG
• INFO
• WARN
• ERROR

Installation

npm install loglevel-colors

defaults

const log = require('loglevel-colors')('Sample');

log.trace(`I'm a trace message!`);
log.debug(`I'm a debug message!`);
log.info(`I'm a info message!`);
log.warn(`I'm a warn message!`);
log.error(`I'm a error message!`);

[Sample] DEBUG: I'm a debug message!
[Sample] INFO: I'm a info message!
[Sample] WARN: I'm a warn message!
[Sample] ERROR: I'm a error message!

Setting WARN as the default level

const log = require('loglevel-colors')('Sample', 'WARN');

log.trace(`I'm a trace message!`);
log.debug(`I'm a debug message!`);
log.info(`I'm a info message!`);
log.warn(`I'm a warn message!`);
log.error(`I'm a error message!`);

[Sample] WARN: I'm a warn message!
