Moai Logger Core

The core engine responsible for managing log levels, shared identity (id), and optional configurations for formatting, normalization, and handlers.

  • Multiple logger instances can share a single core by specifying the same id, enabling centralized and synchronized log level management across instances.

  • It supports dynamic runtime control of log verbosity:

    • setLevel(level): updates the active log level
    • resetLevel(): restores to the initial log level

  • Factory When calling logry(), the system checks the Logger Core map by id.
    If found, it returns a Logger linked to that core; otherwise, it creates a new core and returns a Logger.

⚠ī¸ Note: Core configurations are fixed per LoggerCore identified by id.
Creating a logger with an existing id ignores new core-level options and logs a warning.

ℹī¸ Note: In Edge runtime environments, the Logger Core concept is intentionally not available.
This design aligns with the stateless and ephemeral nature of Edge environments.
