@gvray/logger / filterLevel

Function: filterLevel()

filterLevel(minLevel): LogMiddleware

Defined in: middleware/filterLevel.ts:20

Middleware that drops log entries below a minimum level.

Unlike the logger's level option (which filters at output time), this middleware filters within the pipeline, so later middleware and listeners also never see the dropped entries.

Parameters

minLevel

LogLevel

Minimum level required for a log to proceed.

Returns

LogMiddleware

A LogMiddleware instance.

Example

logger.use(filterLevel(LogLevel.WARNING));
logger.info('hidden');   // not output
logger.warn('visible');  // output
