Linked Log Level Manager for LogLayer

A log level manager for LogLayer that keeps log levels synchronized between parent and children. Parent and child changes affect each other bidirectionally.

Installation

npm install @loglayer/log-level-manager-linked

Usage

import { LogLayer, ConsoleTransport, LogLevel } from "loglayer";
import { LinkedLogLevelManager } from '@loglayer/log-level-manager-linked';

const parentLog = new LogLayer({
  transport: new ConsoleTransport({
    logger: console
  }),
}).withLogLevelManager(new LinkedLogLevelManager());

const childLog = parentLog.child();

// Parent changes affect children
parentLog.setLevel(LogLevel.warn);
childLog.info('This will not be logged'); // Not logged (affected by parent)

// Child changes also affect parent
childLog.setLevel(LogLevel.debug);
parentLog.debug('This will be logged'); // Logged (affected by child)
childLog.debug('This will be logged'); // Logged (child changed to debug)
