Morgan

Morgan is a Node.js HTTP logging middleware designed to record incoming requests and outgoing responses. It captures request metadata and timing to facilitate API request auditing and server performance monitoring.

The project utilizes token-based string interpolation and custom log tokens to extract specific properties from HTTP objects. It supports multi-destination logging by routing formatted log strings to various writable streams and employs log output sanitization to escape control characters.

Additional capabilities include predicate-based log filtering to conditionally omit entries and the ability to trigger immediate log timing upon receiving a request.

Features

HTTP Traffic Logging - Provides a dedicated middleware for recording incoming and outgoing HTTP traffic in Node.js applications.
Token-Based Interpolation - Uses named tokens and extractor functions to dynamically build log strings from HTTP request and response metadata.
Request Middleware - Provides middleware to intercept the Node.js request-response cycle for metadata and timing capture.
Application API Auditing - Captures detailed HTTP metadata to create an audit trail of all API interactions.
Request Logging - Records details of incoming and outgoing HTTP traffic for diagnostic and monitoring purposes.
Web Server Performance Monitoring - Tracks response times and status codes to identify slow endpoints and frequent server errors.
Log Token Extractors - Provides custom tokens that extract specific metadata from requests and responses to inject into log entries.
Log String Sanitizers - Sanitizes log output by escaping control characters to prevent log injection attacks.
Character Escaping - Escapes non-printable control characters in request data to prevent log injection attacks.
Log Entry Filters - Allows conditionally omitting log entries based on custom boolean predicate functions.
Writable Stream Integration - Routes formatted log messages to any Node.js writable stream, including the console and file system.
Log Event Filters - Prevents specific requests from being logged based on custom conditions, such as HTTP status codes.
Application Log Redirection - Manages application logs by routing HTTP request data to various output destinations and filtering noise.
Application Log Routing - Directs log entries to specific writable streams like the console or rotating files.
Request Timing Logs - Supports immediate log writing upon request receipt to capture timing without waiting for the response.
Database and Backend - HTTP request logger middleware for Node.js applications.
Loggers, Errors & Reporting - Listed in the “Loggers, Errors & Reporting” section of the Awesome Micro awesome list.

Logback is a Java logging framework used to record system events and diagnostic messages through a programmable API. It serves as a concrete implementation of the Simple Logging Facade for Java (SLF4J) and provides a structured logging engine for outputting events in machine-readable formats like JSON. The system distinguishes itself through an asynchronous log processor that utilizes circular queues and background workers to reduce performance overhead. It also features a log file rotation manager for size-based or time-based rollover with automatic compression, and the ability to update log
