Functions

• configureApp
• getLogger

configureApp

Initializes the global logging system.

Call this once at application startup to configure the log level and backend. If no backend is specified, logtape is used when available, otherwise falls back to console output.

| Function | Type | | -------------- | -------------------------------------------- | | configureApp | (args?: ConfigureAppArgs) => Promise<void> |

Parameters:

• args: - Configuration options for level and backend.

Examples:

await configureApp({ level: "debug" });

getLogger

Creates a logger for a specific subsystem.

The returned logger automatically adapts if the backend changes after creation (e.g., when {@link configureApp} is called later).

| Function | Type | | ----------- | --------------------------------------------------- | | getLogger | (subsystem: readonly string[]) => Promise<Logger> |

Parameters:

• subsystem: - Hierarchical category path for the logger.

Returns:

A logger instance scoped to the subsystem.

Examples:

const logger = await getLogger(["faremeter", "client"]);
logger.info("Client initialized", { version: "1.0.0" });
