micro-logs

micro-logs

A minimal, console-only logging utility that behaves exactly like logs-gateway console logging, with optional fail-fast error throwing.

Features

• Console-only: Zero support for files, transports, or complex routing.
• Environment-driven: Configuration via environment variables.
• Logs-gateway parity: Identical log-level semantics and behavior.
• Fail-fast: Error logs throw by default (configurable).
• Zero dependencies: Lightweight and predictable.

Installation

npm install micro-logs

Usage

import { Logger } from 'micro-logs';

const logger = new Logger({
  packageName: 'my-service',
  debugNamespace: 'api:v1' // Optional
});

logger.info('Server started');
logger.debug('Processing request'); // Suppressed by default
logger.error('Database connection failed'); // Throws by default

Configuration

Log Levels

Logs are filtered based on a minimum threshold. Supported levels (ordered):

1. verbose
2. debug
3. info (default)
4. warn
5. error

Configure via: {ENV_PREFIX}_LOG_LEVEL (e.g., LOG_LEVEL=debug).

DEBUG Namespace

Enable verbose and debug logs for specific namespaces without lowering the global level.

Configure via: DEBUG (e.g., DEBUG=api:*,auth).

Error Throwing

By default, calling logger.error() will throw an Error.

Configure via: {ENV_PREFIX}_THROW_ERROR (values: true | false).
