This project is a namespace-based logging utility for JavaScript runtimes, including Node.js and web browsers. It provides a system for categorizing output into distinct namespaces to enable filtered visibility and color-coded identification of log sources. The utility allows for dynamic log control, where output streams can be toggled on or off via environment variables or method calls without restarting the application. It includes an execution time profiler that calculates the elapsed time between consecutive log calls to identify performance bottlenecks. Further capabilities include the
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
spdlog is a high-performance C++ logging library designed to record diagnostic messages and application events. It serves as an asynchronous logging framework and thread-safe library that coordinates access across concurrent threads to maintain message integrity. The project functions as a multi-target log router, distributing single events to multiple destinations such as consoles, files, and system daemons. It includes a log rotation manager that handles file lifecycles through basic, rotating, or daily rollover strategies to prevent disk exhaustion. The library covers a broad range of cap
Zerolog is a structured logging library for Go designed for high-performance event capture and observability. It focuses on generating machine-readable JSON output while minimizing memory overhead through zero-allocation buffer encoding and strongly-typed field validation. The library distinguishes itself by providing a chainable, context-aware interface that allows developers to bind trace identifiers and metadata directly to request lifecycles. It supports complex diagnostic workflows by enabling independent logger instances, custom output routing to multiple concurrent destinations, and ev
This project is a JavaScript logging utility and namespace-based debugger used for printing formatted, color-coded debug messages to the console in Node.js, web browsers, and Deno. It serves as a console output formatter and execution time profiler to help identify bugs and track program flow.
The main features of debug-js/debug are: Console Log Formatters, Namespace-Based Log Filtering, Performance Profiling Tools, JavaScript and TypeScript Debugging, Namespace-Based Debuggers, Environment Variable-Based Configuration, Log Management, Logging Utilities.
