What problem does it solve?

Guides developers to choose and configure Python logging correctly by distinguishing when to use the stdlib logging API versus the loguru library for apps and libraries.

Core Features & Use Cases

  • Guidance on selecting stdlib logging for libraries and ecosystem integration.
  • Clear configuration patterns for handlers, levels, and structured context in apps and CLIs.
  • Best practices for avoiding cross-framework conflicts and ensuring observable logging.

Quick Start

Decide at project startup whether to use stdlib logging for libraries or loguru for applications, and implement the chosen setup.

FAQPage Schema
What's the best way to configure Python logging for an application versus a library?

The best way to configure Python logging is to use stdlib logging for libraries to ensure ecosystem integration, and loguru for applications to gain structured context. Configuration must be placed at the application entry point to maintain stable logging boundaries.

How do I avoid mixed logging strategies when using loguru and stdlib logging together?

To avoid mixed logging strategies, decide at project startup whether to use stdlib logging or loguru. You must enforce a single choice across your application or CLI and place all configuration at the entry point to prevent cross-framework conflicts.

Why does my Python library logging configuration conflict with the host application?

Python library logging conflicts occur when libraries configure their own handlers instead of using stdlib logging. Libraries should avoid adding handlers and rely on the application entry point to define predictable logging boundaries and handlers.

When do I need to use loguru instead of the standard logging module for my CLI?

You need to use loguru for a CLI when you require structured context and easier configuration patterns than stdlib logging. Loguru provides clear setup for handlers and levels in applications, while stdlib logging is better suited for libraries.

Can I use stdlib logging for ecosystem integration without causing cross-framework conflicts?

Yes, you can use stdlib logging for ecosystem integration by ensuring your library only adds a NullHandler and avoids configuration. The application entry point must enforce predictable logging boundaries to prevent cross-framework conflicts.
