hapi-bunyan-lite - basic Hapi Bunyan integration

Minimalistic Bunyan integration for Hapi - forwards Hapi log events to bunyan

Goals

forward Hapi log events to Bunyan
assign log level based on existence of tags (trace, debug, info, warn, error, fatal) or use configurable default

Installation

npm install --save https://github.com/jeffbski/hapi-bunyan-lite/archive/v0.2.0.tar.gz

Usage

var bunyan = require('bunyan');
var Hapi = require('hapi');

var myRootLogger = bunyan.createLogger({
  name: 'myapp',
  stream: process.stdout,
  level: 'debug'
});

// Optional preprocess function which allows you to modify or
// augment log object and related info before it gets logged
var optionalPreProccessDataFn = function (objLog, event, tags, request) {
  // adding property to objLog, currently contains `.data` with log data
  objLog.foo = 'bar';
  // Here we add the tag "new-tag" to everything.
  event.tags.push('new-tag');
};

var plugins = [{
  plugin: require('hapi-bunyan-lite'),
  options: {
    logger: myRootLogger,
    defaultLogLevel: 'info',
    preProcessData: optionalPreProccessDataFn
  }
}];

var server = Hapi.createServer('localhost', 3000);

var routes = [
  { method: 'GET', path: '/', handler: function (request, reply) {
    request.log(['warn'], 'request at warn');
    request.log(['mytag'], 'request at default');
    reply('Hello World');
  }}
];
server.route(routes);

server.pack.register(plugins, function (err) {
  if (err) { throw err; }
  console.log('hello');
  server.log(['debug'], 'server logging at debug');
  server.log(['mytag'], 'server logging at default');
  server.start();
});
