debugnyan

debugnyan

A logging library that combines the simplicity and convenience of debug with the power of bunyan.

Status

Installation

Install the package via npm:

$ npm install debugnyan --save

Usage

Create a logger by giving it a namespace and then call bunyan's log methods on the returned instance.

By default, similarly to debug's behaviour, loggers do not output any content. Each logger output can be selectively activated by using the DEBUG environment variable. Pattern matching is based on the logger's name and it can optionally contain colons (:) to create (sub)-components properties on the logger instance.

Consider a logger named foo:bar:biz:

• this creates a bunyan logger with name foo
• and a bunyan (simple) child logger with property component equal to bar.

var logger1 = require('debugnyan')('foo');
var logger2 = require('debugnyan')('foo:bar');

logger1.debug('net');
logger2.debug('qux');

Example output with DEBUG=foo:

DEBUG=foo node example.js

{"name":"foo","hostname":"ruimarinho","pid":1,"level":20,"msg":"net","time":"2016-10-04T18:54:14.530Z","v":0}
{"name":"foo","hostname":"ruimarinho","pid":1,"component":"bar","level":20,"msg":"qux","time":"2016-10-04T18:54:14.531Z","v":0}

Example output with DEBUG=foo:bar:

DEBUG=foo:bar node example.js

{"name":"foo","hostname":"ruimarinho","pid":2,"component":"bar","level":20,"msg":"qux","time":"2016-10-04T18:55:08.217Z","v":0}

The prefix and suffix for each component is also customizable:

var logger = require('debugnyan')('foo', {}, { suffix: 'module' });
