Logger SDK for Node.js

A simple and effective logging SDK for Node.js applications that sends logs to your centralized logging service.

Installation

npm install @yourlogger/node-logger
# or
yarn add @yourlogger/node-logger

Quick Start

const { Logger } = require('@yourlogger/node-logger');

// Initialize the logger
const logger = new Logger({
  apiKey: 'your-api-key',
  projectId: 'your-project-id'
});

// Send logs
logger.info('Application started');
logger.warn('Resource usage high', { cpu: '80%', memory: '75%' });
logger.error('Failed to connect to database', { error: 'Connection timeout' });

API Reference

Initialization

const logger = new Logger({
  apiKey: 'your-api-key',         // Required: Your API key
  projectId: 'your-project-id',    // Required: Your project ID
  apiUrl: 'https://api.logger.com', // Optional: API endpoint (default: https://api.logger.com)
  defaultContext: {                // Optional: Default context included with all logs
    service: 'user-service',
    environment: 'production'
  }
});

Methods

• logger.info(message, context?) - Log an informational message
• logger.warn(message, context?) - Log a warning message
• logger.error(message, context?) - Log an error message
• logger.debug(message, context?) - Log a debug message

Each method returns a Promise that resolves to a boolean indicating whether the log was successfully sent.

Context

All methods accept an optional context object which will be merged with the default context:

logger.info('User logged in', { 
  userId: 'user123', 
  loginMethod: 'email' 
});
