Transports

Transports control where logs are sent. Crowlog includes built-in transports and supports custom implementations.

Overview

A transport is simply a function that receives log data and handles it in some way - writing to stdout, storing in memory, sending to a remote service, etc.

type LoggerTransport = (args: LoggerTransportLogArgs) => void;

Every log passes through all configured transports:

const logger = createLogger({
  namespace: 'my-app',
  transports: [
    createStdoutLoggerTransport(), // Console
    createInMemoryLoggerTransport(), // Memory
    myCustomFileTransport() // Custom
  ]
});

// This log goes to all three transports
logger.info('Hello world');

Built-in Transports

• Stdout Transport - Outputs logs to stdout (console) in JSON format
• In-Memory Transport - Stores logs in memory for testing and debugging
