==========

Using node-bunyan as koa logging middleware

# Installation

```

npm install koa-bunyan

```

## Example

```Javascript

var koaLogger = require('koa-bunyan');

var koa = require('koa');

var app = koa();

var bunyan = require('bunyan');

// setup you logger instance

var logger = bunyan.createLogger({name: "myapp"});

app.use(koaLogger(logger, {

    // which level you want to use for logging?

    // default is info

    level: 'debug',

    // this is optional. Here you can provide request time in ms,

    // and all requests longer than specified time will have level 'warn'

    timeLimit: 100,

    headers: ['Accept']

    // optional - provide a list of request headers you'd like to log

}));

```

```bash

// then start server

// let we say... node app.js | ./node_modules/bunyan/bin/bunyan -o short

// result

Logs also can go to somewhere else. It depends on you passed logger configuration.
