  PinoLoggerProvider,
  PinoLoggerProviderOptionsBuilder

const options = new PinoLoggerProviderOptionsBuilder()
  .fromEn('MY_APP_LOG_')
  .build();

await using loggerProvider = createPinoLoggerProvider(
  { level: 'information', envVarPrefix: 'MY_APP_LOG_' }
);

const logger = loggerProvider.getLogger(
  'my-context'
);

logger.information(
  'started'
);

Environment Variables
