@rollercoaster-dev/rd-logger v0.3.1

@rollercoaster-dev/rd-logger

A neurodivergent-friendly logger for Rollercoaster.dev projects.

Installation

npm install @rollercoaster-dev/rd-logger
# or
yarn add @rollercoaster-dev/rd-logger
# or
pnpm add @rollercoaster-dev/rd-logger

Usage

Import the logger and start logging:

import { Logger } from '@rollercoaster-dev/rd-logger';

const logger = new Logger({
  level: 'debug', // Set the desired log level
});

logger.info('Application starting...');
logger.debug('Debugging some initial setup.');
logger.warn('Something seems off.');
logger.error('An error occurred!', new Error('Example error'));

Features

The logger provides several features designed for clarity and ease of use:

• Neuro-friendly formatting: Uses colors, icons, and consistent spacing to improve readability, especially for neurodivergent developers.
• Multiple log levels: Supports standard levels like debug, info, warn, error, fatal.
• Human-readable timestamps: Displays timestamps in a clear, understandable format.
• Structured context: Allows attaching additional key-value data to log messages.
• Request context propagation (optional): Integrates with web frameworks to automatically include request IDs in logs for easier tracing.
• Framework adapters: Provides specific adapters for seamless integration:
  • Hono: Middleware for the Hono framework.
  • Express: Middleware for the Express framework.
  • Generic: Functions for wrapping arbitrary code blocks or background tasks in a logging context.
• Customizable: Allows configuration of log levels, formatting, and more.
• Accessible: Aims to follow accessibility best practices in output formatting.

Query Logger

The package includes an optional QueryLogger to help track database query performance.

import { Logger, QueryLogger } from '@rollercoaster-dev/rd-logger';

const logger = new Logger();
const queryLogger = new QueryLogger(logger, {
  slowQueryThreshold: 150, // Log queries slower than 150ms as warnings
  logDebugQueries: true,   // Log all queries at debug level
});

// Example usage (e.g., inside a database adapter)
const startTime = Date.now();
const result = await databaseClient.execute(sql, params);
const duration = Date.now() - startTime;

// The `requestId` typically comes from the framework adapter's context (e.g., req.id)
const requestId = getCurrentRequestId(); // Replace with your actual method to get the ID
queryLogger.logQuery(sql, params, duration, 'PostgreSQL', requestId);

// Later, you can retrieve stats:
const stats = queryLogger.getStats();
console.log('Query Stats:', stats);

• Publish Workflow: Automatically publishes the package to npm when a new release is created

Versioning and Releases

This project follows Semantic Versioning and uses Conventional Commits for commit messages.

Creating a Release

To create a new release, you can use one of the following commands:

# Create a patch release (0.0.x)
pnpm release:patch

# Create a minor release (0.x.0)
pnpm release:minor

# Create a major release (x.0.0)
pnpm release:major

# Create a prerelease (alpha)
pnpm release:alpha

# Create a prerelease (beta)
pnpm release:beta

Alternatively, you can use the GitHub Actions workflow "Create Release" to create a new release directly from GitHub.
