    LOKE Logger

    NPM Version Build Status

    A multi-target logger tailored for LOKE Group and based around LOKE standards.

    Currently supports console output and syslog.

    Overview

    In version 3.x the api is a subset of console

    it includes .debug(), .log(), .info(), .warn() and .error().

    in addition is a withPrefix method that creates a logger child logger with a prefix;

    const logger = require("loke-logger").create();
    
    logger.error("Lorem ipsum");
    logger.warn("dolor sit amet consectetur");
    
    const httpLogger = logger.withPrefix("HTTP");
    
    httpLogger.info("eiusmod tempor incididunt ut");
    httpLogger.debug("labore et dolore magna aliqua");

    create() Options

    There are a number of options when configuring the logger;

    showDebug

    Type: boolean
    Default: false when NODE_ENV=production, otherwise true

    Whether or not debug level logs should be emitted.

    syslog

    Type: boolean
    Default: false

    This option adds syslog udp messages to the output streams, console messages will still be emitted.

    systemdPrefix

    Type: boolean
    Default: true when JOURNAL_STREAM set, otherwise false

    This option prefixes stdout with systemd's severity syntax

    metricsRegistry

    Type: Object

    A prom-client register to add metrics to.

    const { register } = require("prom-client");
    const logger = require("loke-logger").create({
      metricsRegistry: register,
    });
    
    logger.error("Lorem ipsum");

    This adds the metric log_messages_total with the labels prefix and severity.
