@vevkit/saga-pino

Pino transport for @vevkit/saga logger.

Installation

npm install @vevkit/saga-pino pino pino-pretty

Usage

Basic Usage

import { Logger } from '@vevkit/saga';
import { PinoTransport } from '@vevkit/saga-pino';

const logger = new Logger({
  transports: [
    new PinoTransport()
  ]
});

logger.info('Hello from VevKit!');

Pretty Printing

Enable pretty printing for development:

const logger = new Logger({
  transports: [
    new PinoTransport({
      pretty: true // Uses default pretty printing options
    })
  ]
});

Customize pretty printing:

const logger = new Logger({
  transports: [
    new PinoTransport({
      pretty: {
        colorize: true,
        translateTime: 'UTC:yyyy-mm-dd HH:MM:ss',
        ignore: 'hostname,pid'
      }
    })
  ]
});

Custom Serializers

Add custom serializers for specific properties:

const logger = new Logger({
  transports: [
    new PinoTransport({
      serializers: {
        user: (user) => ({
          id: user.id,
          role: user.role
          // Omit sensitive information
        })
      }
    })
  ]
});

logger.info('User action', { 
  user: { 
    id: 123, 
    role: 'admin',
    password: 'secret' // Will be omitted by serializer
  }
});

Custom Pino Instance

Use your own Pino instance:

import pino from 'pino';

const pinoInstance = pino({
  // Your custom Pino configuration
});

const logger = new Logger({
  transports: [
    new PinoTransport({
      instance: pinoInstance
    })
  ]
});
