Structured and leveled logging libraries for capturing, formatting, and shipping application logs to observability pipelines (Winston, Pino, Loguru).
Packages in Logging
Kind
Sort:Used by Most Apps
Pino
A super fast, low-overhead JSON logger for Node.js applications.
pino-pretty
A CLI and stream that prettifies Pino's ndjson log lines into readable, colorized terminal output for local development.
tracing
Structured, application-level diagnostics for async Rust programs, built around scoped spans and events.
Winston
A battle-tested Node.js logging library with pluggable transports, custom formats, and multiple log levels.
log
A lightweight logging facade for Rust that decouples libraries from the logging implementation applications choose.
Logrus
Structured, pluggable logging for Go with a stdlib-compatible API and level-based hooks.
OpenTelemetry Python SDK
The reference implementation of the OpenTelemetry API for Python - traces, metrics, and logs
debug
A tiny, zero-config JavaScript debugging utility with namespaced, color-coded output for Node.js and the browser.
loguru
A drop-in replacement for Python's standard logging module that makes logging enjoyable, with almost no setup required.
electron-log
Zero-dependency logging for Electron, Node.js, and NW.js apps with file, console, and remote transports.
morgan
Battle-tested HTTP request logger middleware for Node.js and Express.
env_logger
Environment-variable-configured logging backend for Rust's log crate
zerolog
A zero-allocation, chaining-API JSON logger for Go built for both structured production output and pretty local development logs.
structlog
Structured, typed logging for Python built on plain functions and dictionaries instead of a bespoke logging DSL.
logr
A minimal, backend-agnostic structured logging API for Go, letting libraries log without coupling to any specific logging implementation.
pino-http
The fastest structured HTTP request logger for Node.js, built directly on pino and ready to drop into any http server or Express app.
go-systemd
Go bindings for systemd: socket activation, journald logging, D-Bus unit control, and sd_notify readiness signals in pure Go.
winston-daily-rotate-file
A Winston transport that rotates log files daily, by size, and with automatic compression
Monolog
The PSR-3 logging library that sends PHP logs to files, sockets, databases, and dozens of web services
handlers
A collection of composable HTTP middleware for Go's net/http — logging, compression, CORS, proxy headers, and panic recovery.
tint
A zero-dependency slog.Handler for Go that writes tinted, colorized console logs.
psr/log
The PSR-3 common logger interface that lets PHP libraries accept any logger without depending on a specific implementation.
nest-winston
Nest module wrapper wiring winston logging into NestJS's DI and Logger interface
redux-logger
Redux middleware that logs every dispatched action to the console with previous and next state snapshots.
