New Features

pino.transport()

Create a a stream that routes logs to a worker thread that
wraps around a Pino Transport.

const pino = require('pino')
const transport = pino.transport({
  target: 'some-transport',
  options: { some: 'options for', the: 'transport' }
})
pino(transport)

Multiple transports may also be defined, and specific levels can be logged to each transport:

const pino = require('pino')
const transports = pino.transport({
  targets: [{
    level: 'info',
    target: 'some-transport',
    options: { some: 'options for', the: 'transport' }
  }, {
    level: 'trace',
    target: '#pino/file',
    options: { destination: '/path/to/store/logs' }
  }]
})
pino(transports)

For more on transports, how they work, and how to create them see the Transports documentation.

`pino.multistream()``

We have embedded a part of pino-multi-stream into pino itself, so you would be able to write to multiple streams from the same pino instance:

var fs = require('fs')
var pino = require('pino')
var streams = [
  {stream: fs.createWriteStream('/tmp/info.stream.out')},
  {level: 'debug', stream: fs.createWriteStream('/tmp/debug.stream.out')},
  {level: 'fatal', stream: fs.createWriteStream('/tmp/fatal.stream.out')}
]

var log = pino({
  level: 'debug' // this MUST be set at the lowest level of all the destinations
}, pino.multistream(streams))

log.debug('this will be written to /tmp/debug.stream.out')
log.info('this will be written to /tmp/debug.stream.out and /tmp/info.stream.out')
log.fatal('this will be written to /tmp/debug.stream.out, /tmp/info.stream.out and /tmp/fatal.stream.out')

This differs from pino.transport() as all the streams will be executed within the main thread, i.e. the one that created the pino instance.

Added TypeScript types

Types have been added to the the project, so you can now use pino with TypeScript without downloading any additional types: you should remove @types/pino from your project. The following typescript example would now work correctly:

import { pino } from "pino";

const log = pino();

log.info("hello world");
log.error("this is at error level");
log.info("the answer is %d", 42);
log.info({ obj: 42 }, "hello world");
log.info({ obj: 42, b: 2 }, "hello world");
log. info({ obj: { aa: "bbb" } }, "another");

Breaking Changes

Dropped Node.js v10.x

Node.js v10 went out of LTS/Maintenance in April 2021.
We are dropping support.

Apply err serializer everywhere

We will start applying the err serializer also to Error objects passed in as first argument to log methods, e.g. log.info(new Error('kaboom')) will pass through the serializer.
