Logging

Logging in v2 was confusing as both application logs and system (internal) logs were using the same logger. We have simplified this as follows:

• Internal logs are now handled using the standard Go slog logger. This is configured using the logger option in the application options. By default, this uses the tint logger.
• Application logs can now be achieved through the new log plugin which utilises slog under the hood. This plugin provides a simple API for logging to the console. It is available in both Go and JS.
