Full Changelog: 2.1.1...2.1.2

Release 2.1.0

Feature: Child Loggers

You can create an specialized logger for a part of your app with bound static context/properties. The child logger will inherit its parent config: level, format, stream and context. If the parent logger has a context returned by parent.getContext(), the conflicting child logger context will take precedence

let child = logger.child({component: 'client'});
child.info('Startup');
// {"component":"client","time":"2015-12-23T11:47:25.862Z","lvl":"INFO","msg":"Startup"}

Performance improvements

2.0.0

Sets the node environment for this version to be node>6
Feature:

• Make node 6 compatible (#39)

BREAKING CHANGES:

• Dates are formatted always as ISOString when used as parameter without placeholders

 logger.info('Today is', new Date());
// Before: "msg": "Today is Thu Jan 01 1970 01:00:00 GMT+0100 (CET)"
// Now:    "msg": "Today is 1970-01-01T00:00:00.000Z"

• Errors will incorporate stack traces instead of the node4 bracket notation when used as parameter without placeholders

logger.info('Oh oh!', new Error('boom')) 
// Before: "msg": "Oh oh! [Error: boom]"
// Now:    "msg": "Oh oh! Error: boom\n    at repl:1:23\n    at sigintHandlersWrap (vm.js:22:35)\n    at sigintHandlersWrap (vm.js:96:12)\n    at ContextifyScript.Script.runInThisContext (vm.js:21:12)\n    at REPLServer.defaultEval (repl.js:340:29)\n    at bound (domain.js:280:14)\n    at REPLServer.runBound [as eval] (domain.js:293:12)\n    at REPLServer.<anonymous> (repl.js:538:10)\n    at emitOne (events.js:101:20)\n    at REPLServer.emit (events.js:188:7)"

When used with placeholders the behavior is consistent across versions

// Both in 1.x and 2.x, the output is the same
logger.info('Today is %s', new Date())
// "msg":"Today is Thu Jan 01 1970 01:00:00 GMT+0100 (CET)"
logger.info('Oh oh! %s', new Error('boom'))
// "msg":"Oh oh! Error: boom"

Inherited breaking changes explanation
Node6 incorporated these breaking changes that we inherit because we delegate in utils.format (ref https://github.com/nodejs/node/wiki/Breaking-changes-between-v5-and-v6#util)

• util: Change how Error objects are formatted
• util,test: Use consistent Date representation for util/inspect
