GitHub Star Comparison
| No | Name | GitHub Stars | Description | Trend | License | Type | Official Site |
|---|---|---|---|---|---|---|---|
| 1 | Winston | ⭐ 23.8k | Most popular logging library for TypeScript/Node.js (13.9 million weekly downloads). Provides rich and customizable API with format and transport options. Enhanced development experience in TypeScript projects through type definition support. | Maintains largest market share in 2025. Established as stable choice for TypeScript developers. However, migration to Pino increasing in performance-focused projects. Default configuration improvements recognized as challenges. | MIT | Traditional Logger | Official |
| 2 | Pino | ⭐ 15.8k | High-performance structured logging framework for TypeScript/Node.js (11.5 million weekly downloads). Defaults to JSON output, achieves excellent responsiveness through asynchronous log processing. Over 5x faster than Winston, optimized for production use. | Rapidly growing as first choice for performance-focused projects in 2025. Enhanced development experience through enriched TypeScript type definitions (@types/pino). Adoption expanding in cloud-native and microservices environments. | MIT | JSON Logger | Official |
| 3 | debug (TypeScript) | ⭐ 11.3k | TypeScript-compatible version of lightweight debug-specific library. Enhanced development experience in TypeScript projects through type definitions. Specialized for flexible control via environment variables and debug information display during development. Internally used by many TypeScript libraries. | Widely adopted as internal debug functionality in TypeScript library development in 2025. Maintains support from TypeScript developers through type safety and ease of debugging. Lightweight and simple nature valued, contributing to improved development experience. | MIT | Debug Logger | Official |
| 4 | tslog | - | Logging library designed specifically for TypeScript (183,000 weekly downloads, 1,410 GitHub stars). Fully integrated with TypeScript type system, provides beautiful console output and browser support. Design emphasizing developer experience. | Attention increasing in TypeScript-focused projects in 2025. Being discovered as alternative choice for developers experiencing issues with Pino. Adoption trend increasing in small to medium-scale TypeScript projects. | MIT | Type-safe Logger | Official |
| 5 | console (TypeScript) | - | Standard console output API for TypeScript/JavaScript. Enables type-safe usage, suitable for rapid log output during development and debugging stages. Immediately available without configuration, but has feature limitations in production environments. | Usage continues in early stages of TypeScript development and prototyping in 2025. Enables safer usage than traditional JavaScript through type checking. Migration to dedicated libraries recommended for full-scale applications. | Web Standard | Native API | Official |
| 6 | typescript-logging | - | Logging library specifically for TypeScript (23,478 weekly downloads, 98 GitHub stars). Provides type-safe logging API leveraging TypeScript characteristics. For niche applications but equipped with specialized features for pure TypeScript environments. | Selection examples by TypeScript purists still exist in 2025. Market share is limited, but adoption seen in projects prioritizing type safety above all. Maintenance and community size pointed out as challenges. | Apache-2.0 | Type-focused Logger | Official |
