Benchmarks

Benchmarks log each request/response pair while returning 'hello world', using autocannon with 100 connections and 10 pipelined requests (autocannon -c 100 -p 10 http://localhost:3000).

• restify.auditLogger + bunyan: 5483.82 req/sec
• restify-bunyan-logger: 6306.73 req/sec
• restify-logger: 7485.28 req/sec
• restify-pino-logger: 8207.46 req/sec
• restify-pino-logger (extreme): 8789.28 req/sec
• restify-pino-logger (without restify): 22240.73 req/seq
• restify-pino-logger (without restify and extreme): 25536 req/sec

All benchmarks where taken on a Macbook Pro 2013 (2.6GHZ i7, 16GB of RAM).

Whilst we're comparing restify-pino-logger against restify-logger this isn't really a fair contest.

restify-logger sits on top of morgan.

Morgan doesn't support logging arbitrary data, nor does it output JSON. Further Morgan uses a form of eval to achieve high speed logging. Whilst probably safe, using eval at all tends to cause concern, particular when it comes to server-side JavaScript.

The fact that restify-pino-logger achieves higher throughput with JSON logging and arbitrary data, without using eval, serves to emphasise the high-speed capabilities of restify-pino-logger.

With restify-pino-logger you can have features, safety and speed.

Install

npm i restify-pino-logger --save

Example

'use strict'

var restify = require('restify')
var server = restify.createServer({name: 'app'})

server.use(require('restify-pino-logger')())

server.get('/', function (req, res) {
  req.log.info('something else')
  res.send('hello world')
})

server.listen(3000)

API

restify-pino-logger has the same options of pino, look at them there. restify-pino-logger attaches some listeners to the request, so that it will log when the request is completed.
