Parseable-winston NPM

Parseable-Winston

Parseable transport plugin for the popular Winston logging framework.

Dependencies

Installation

npm install parseable-winston

yarn add parseable-winston

Usage

Package is cjs and es6 compatible.

Logs are buffered in memory and flushed periodically for more efficient ingestion. By default a maxEntries of 250, and flushInterval of 5 seconds are used.

// Using cjs
const { ParseableTransport } = require('parseable-winston')
const winston = require('winston')

const parseable = new ParseableTransport({
  url: process.env.PARSEABLE_LOGS_URL, // Ex: 'https://parsable.myserver.local/api/v1/logstream'
  username: process.env.PARSEABLE_LOGS_USERNAME,
  password: process.env.PARSEABLE_LOGS_PASSWORD,
  logstream: process.env.PARSEABLE_LOGS_LOGSTREAM, // The logstream name
  tags: { tag1: 'tagValue' } // optional tags to be added with each ingestion
})

const logger = winston.createLogger({
  levels: winston.config.syslog.levels,
  transports: [parseable],
  defaultMeta: { instance: 'app', hostname: 'app1' }
})

logger.info('User took the goggles', { userid: 1, user: { name: 'Rainier Wolfcastle' } })
logger.warning('The goggles do nothing', { userid: 1 })

Tuning the default buffering options

const parseable = new ParseableTransport({
  url: process.env.PARSEABLE_LOGS_URL,
  username: process.env.PARSEABLE_LOGS_USERNAME,
  password: process.env.PARSEABLE_LOGS_PASSWORD,
  logstream: process.env.PARSEABLE_LOGS_LOGSTREAM,
  buffer: { maxEntries: 100, flushInterval: 5000 }
})

Other optional parameters
