Usage

Initialization

/** @file: logger.js */
import { Logger, logLevels, filter } from "@hishprorg/sed-voluptas-non";

export const logger = new Logger(
  "app", // Root logger name
  logLevels(), // Define log levels. By default are: verbose, debug, info, warn, error, fatal
  // You can use custom levels by using
  // logLevels("info", "warn", "error")

  {
    // Custom data
    appVersion: "3.1"
    moduleName: "root",
    moduleVersion: "1.0.0"
  }
);

export const child = logger.child(
  // Child logger name
  "auth",

  // Child logger data
  { moduleName: "auth", moduleVersion: "0.3.1" }
);

const criticalLogs = [];

const unsubscribe = logger.subscribe(
  // Subscribe to all logs, they go to console
  (log) => console.log(...log.message.parts),

  // All logs, that level is greater or equal than "warn" will be added to critical logs

  // Severity is determined by index of level in levels array
  // Current array is: verbose, debug, info, warn, error, fatal
  //                             [less] <<<  ^^^^   >> [greater]
  filter(">=", "warn", (log) => criticalLogs.push(log))
)

process.on("SIGINT", () => {
  unsubscribe();
})

Logging

/** @file: index.js */
import { child, logger } from "./logger.js";

const PORT = parseInt(process.env.PORT) || 3000;
logger.subscribe(log => console.log(log));

child.log.debug`Application initialized. Port: ${{ port: PORT }}. Environment: ${{process.env}}`;
// Level:  ^^^^^

// Here goes app

Log format
