Winston is a versatile logging library for Node.js designed to record system events and metadata. It functions as a multi-transport log manager that routes data to various destinations and a structured log formatter that transforms entries into JSON or plain text. The project is distinguished by its pluggable transport architecture, which decouples the logging interface from delivery mechanisms. This allows for the creation of custom transport extensions and the use of hierarchical logger instances to inherit configurations while attaching persistent metadata to downstream messages. The libr
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
Signale is a formatted console logging library for Node.js applications. It serves as a pluggable logging framework and stream-based log router that allows users to record system events using customizable levels, colors, and output styles. The project distinguishes itself as an interactive console logger capable of overwriting previous messages to reduce terminal clutter during long-running tasks. It also functions as an application performance monitor, providing tools to measure and track execution time between specific code points to identify performance bottlenecks. The library covers a b
This project is a structured logging framework and library for Node.js applications. It produces machine-readable log records in JSON format with tiered severity levels, ensuring consistent parsing and centralized storage. The system includes a log stream manager for routing records to multiple destinations, such as files and consoles, and a command line interface for filtering, formatting, and visualizing raw JSON log streams. It supports the creation of child loggers that inherit parent configurations and merge additional contextual metadata. The framework covers a broad range of operation
Dies ist ein Logging-Framework für Node.js, das auf der log4j-Architektur basiert. Es bietet ein System zur Verwaltung hierarchischer Logger und Schweregrad-Schwellenwerte, wodurch Anwendungsereignisse aufgezeichnet und nach Wichtigkeit kategorisiert werden können.
