@pgpmjs/logger

Simple logger utility with yanse colors for consistent logging across packages.

Installation

npm install @pgpmjs/logger

Features

• Colored console output using yanse
• Consistent log formatting
• Namespace support for identifying log sources
• Simple API with log, error, and warn methods

Usage

import { Logger } from '@pgpmjs/logger';

// Create a logger with a namespace
const log = new Logger('my-module');

// Log messages
log.log('This is a regular message');
log.error('This is an error message');
log.warn('This is a warning message');

// Messages will be prefixed with the namespace in color
// [my-module] This is a regular message

API

new Logger(namespace: string)

Creates a new logger instance with the given namespace.

Methods

• log(...args: any[]): void - Log a regular message (cyan namespace)
• error(...args: any[]): void - Log an error message (red namespace)
• warn(...args: any[]): void - Log a warning message (yellow namespace)

Example

import { Logger } from '@pgpmjs/logger';

const dbLog = new Logger('database');
const apiLog = new Logger('api');

dbLog.log('Connected to PostgreSQL');
// Output: [database] Connected to PostgreSQL (with cyan [database])

apiLog.error('Failed to fetch user:', error);
// Output: [api] Failed to fetch user: ... (with red [api])

apiLog.warn('Rate limit approaching');
// Output: [api] Rate limit approaching (with yellow [api])
