winston-redis

A capped Redis transport for winston.

Requirements

  • NodeJS 8.11.x
  • Winston 3.x

Usage

  const winston = require('winston');
  const redisTransport = require('winston-redis');

  const logger = winston.createLogger({
    level: 'info',
    transports: [
      new redisTransport()
    ]
  });

  logger.log({
    level: "info",
    message: "redis is awesome",
    reason: "it's fast" // this will get stored as meta data
  });

This transport accepts the options accepted by the node-redis client:

  • host: (Default localhost) Remote host of the Redis server
  • port: (Default 6379) Port the Redis server is running on.
  • auth: (Default None) Password set on the Redis server

In addition to these, the Redis transport also accepts the following options.

  • redis: Either the redis client or the options for the redis client
  • length: (Default 200) Number of log messages to store.
  • container: (Default winston) Name of the Redis container you wish your logs to be in.
  • channel: (Default None) Name of the Redis channel to stream logs from.
  • meta: (Default {}) Custom fields to add to each log.
  • flatMeta: (Default false) Store meta data at the top level of the object rather than within a child meta object.

Metadata: Logged as JSON literal in Redis
