v3.2.0 / 2019-01-26

SORRY IT TOO SO LONG EDITION

NOTE: this was our first release using Github Projects. See the 3.2.0 Release Project.

New Features!

• [#1471], (@kibertoad) Implement child loggers.
• [#1462], (@drazisil) Add handleRejection support.
  • [#1555], (@DABH) Add fixes from [#1355] to unhandled rejection handler.
• [#1418], (@mfrisbey) Precompile ES6 syntax before publishing to npm.
  • [#1533], (@kibertoad) Update to Babel 7.
• [#1562], (@indexzero) [fix] Better handling of new Error(string) throughout the pipeline(s). (Fixes [#1338], [#1486]).

Bug Fixes

• [#1355], (@DABH) Fix issues with ExceptionHandler (Fixes [#1289]).
• [#1463], (@SerayaEryn) Bubble transport warn events up to logger in addition to errors.
• [#1480], [#1503], (@SerayaEryn) File tailrolling fix.
• [#1483], (@soldair) Assign log levels to un-bound functions.
• [#1513], (@TilaTheHun0) Set maxListeners for Console transport.
• [#1521], (@jamesbechet) Fix Transform from readable-stream using CRA.
• [#1434], (@Kouzukii) Fixes logger.query function (regression from 3.0.0)
• [#1526], (@pixtron) Log file without .gz for tailable (Fixes [#1525]).
• [#1559], (@eubnara) Fix typo related to exitOnError.
• [#1556], (@adoyle-h) Support to create log directory if it doesn't exist for FileTransport.

New splat behavior

• [#1552], (@indexzero) Consistent handling of meta with (and without) interpolation in winston and logform.
• [#1499], (@DABH) Provide all of SPLAT to formats (Fixes [#1485]).
• [#1485], (@mpabst) Fixing off-by-one when using both meta and splat.

Previously splat would have added a meta property for any additional info[SPLAT] beyond the expected number of tokens.

As of logform@2.0.0, format.splat assumes additional splat paramters (aka "metas") are objects and merges enumerable properties into the info. e.g. BE ADVISED previous "metas" that were not objects will very likely lead to odd behavior. e.g.

const { createLogger, format, transports } = require('winston');
const { splat } = format;
const { MESSAGE, LEVEL, SPLAT } = require('triple-beam');

const logger = createLogger({
  format: format.combine(
    format.splat(),
    format.json()
  ),
  transports: [new transports.Console()]
});

// Expects two tokens, but four splat parameters provided.
logger.info(
  'Let us %s for %j',   // message
  'objects',           // used for %s
  { label: 'sure' },   // used for %j
  'lol', ['ok', 'why'] // Multiple additional meta values 
);

// winston < 3.2.0 && logform@1.x behavior:
// Added "meta" property.
//
// { level: 'info',
//   message: 'Let us objects for {"label":"sure"}',
//   meta: ['lol', ['ok', 'why']],
//   [Symbol(level)]: 'info',
//   [Symbol(message)]: 'Let us %s for %j',
//   [Symbol(splat)]: [ 'objects', { label: 'sure' } ] }

// winston >= 3.2.0 && logform@2.x behavior: Enumerable properties
// assigned into `info`. Since **strings and Arrays only have NUMERIC
// enumerable properties we get this behavior!**
//
// { '0': 'ok',
//   '1': 'why',
//   '2': 'l',
//   level: 'info',
//   message: 'Let us objects for {"label":"sure"}',
//   [Symbol(level)]: 'info',
//   [Symbol(message)]: 'Let us %s for %j',
//   [Symbol(splat)]: [ 'objects', { label: 'sure' } ] }

OMG THEY FORGOT TO NAME IT EDITION

v3.0.0-rc0 / 2017-10-02

IT'S-DONE.GIF EDITION

See UPGRADE-3.0.md for a complete & living upgrade guide.

See 3.0.0.md for a list of remaining RC tasks.

• Rewrite of core logging internals: Logger & Transport are now implemented using Node.js objectMode streams.
• Your transports should not break: Special attention has been given to ensure backwards compatibility with existing transports. You will likely see this:

YourTransport is a legacy winston transport. Consider upgrading to winston@3:
- Upgrade docs: https://github.com/winstonjs/winston/tree/master/UPGRADE.md

• filters, rewriters, and common.log are now formats: winston.format offers a simple mechanism for user-land formatting & style features. The organic & frankly messy growth of common.log is of the past; these feature requests can be implemented entirely outside of winston itself.

const { createLogger, format, transports } = require('winston');
const { combine, timestamp, label, printf } = format;

const myFormat = printf(info => {
  return `${info.timestamp} [${info.label}] ${info.level}: ${info.message}`;
});

const logger = createLogger({
  combine(
    label({ label: 'right meow!' }),
    timestamp(),
    myFormat
  ),
  transports: [new transports.Console()]
});

• Increased modularity: several subsystems are now stand-alone packages:
  • [logform] exposed as winston.format
  • [winston-transport] exposed as winston.Transport
  • [abstract-winston-transport] used for reusable unit test suites for transport authors.
• 2.x branch will get little to no maintenance: no feature requests will be accepted – only a limited number of open PRs will be merged. Hoping the [significant performance benefits][perf-bench] incentivizes folks to upgrade quickly. Don't agree? Say something!
• No guaranteed support for node@4 or below: all code will be migrated to ES6 over time. This release was started when ES5 was still a hard requirement due to the current LTS needs.
