+# debugnyan
+
+A logging library that combines the simplicity and convenience of [debug](https://github.com/visionmedia/debug) with the power of [bunyan](https://github.com/trentm/node-bunyan).
+
+## Status
+
+[![npm version][npm-image]][npm-url]
+[![build status][travis-image]][travis-url]
+
+## Installation
+
+Install the package via `npm`:
+
+```bash
+$ npm install debugnyan --save
+```
+
+## Usage
+
+Create a logger by giving it a namespace and then call [bunyan's log methods](https://github.com/trentm/node-bunyan#log-method-api) 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`.
+
+```js
+var logger1 = require('debugnyan')('foo');
+var logger2 = require('debugnyan')('foo:bar');
+
+logger1.debug('net');
+logger2.debug('qux');
+```
+
+*Example output with `DEBUG=foo`*:
+
+```bash
+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`*:
+
+```bash
+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:
+
+```js
+var logger = require('debugnyan')('foo', {}, { suffix: 'module' });
+```
+
+## Tests
+
+```
+$ npm test
+```
