Benchmarks

Benchmarks log each request/response pair while returning 'hello world', using autocannon with 100 connections and pipelining set to 1 (rill can't handle pipelining): autocannon -c 100 -p 1 http://localhost:3000.

• rill-logger: 10529.82 req/sec
• rill-pino-logger: 11849 req/sec
• rill-pino-logger (extreme): 12623.64 req/sec
• rill w/out logger: 17834.55 req/sec

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

Benchmarking against rill-logger is an apples vs oranges situation. rill-logger is for development logging, and has extremely simple (non-JSON) output. However, there's currently no other rill loggers to compare against.

Install

npm i rill-pino-logger --save

Example

Request logging

'use strict'

var rill = require('rill')
var logger = require('rill-pino-logger')

var app = rill()
app.use(logger())

app.use(({log, res}) => {
  log.info('something else')
  res.body = 'hello world'
})

app.listen({port: 3000})

Browser

In keeping with Rill's isomorphic nature, rill-pino-logger works just fine in the browser.

browserify example.js > eg.js

index.html:

<script src=eg.js></script>

If we were to open index.html we would see the examples messages in the console.

If we wish to log via some other mechanism, we can pass a stream:

var websocket = require('websocket-stream')
app.use(logger(websocket('http://localhost:3000', [])))

This would send all logs over websocket to http://localhost:3000.

API

rill-pino-logger has the same options as pino rill-pino-logger will log when a request finishes or errors.

Along with automated request logging, the pino logger facilitates manual logging by adding the pino logger instance to the the context object:

  app.use(({log}, next) => {
    log.info('test')
    return next()
  })
