laabr is a well-formatted pino ⇗ logger for hapi.js ⇗ which is based on the plugin hapi-pino ⇗. It enables optionally to log in JSON for easy post-processing. It listens to various hapi.js events ⇗ and logs in a well-formatted manner. Therefor it is possible to define custom formats alike the morgan ⇗ ones or make use of available presets. Additionally it enables to define own tokens which could be used in custom formats. laabr is the Swabian translation for talking.

The modules standard and ava are used to grant a high quality implementation.

laabr vs. hapi-pino

First of all laabr extends the hapi-pino plugin. So it is possible to use laabr in an almost identical manner like hapi-pino. This plugin provides further features which probably decelerates the logging a bit, but it should be faster than the alternatives anyway. The following features are provided:

  • Easy out of the box usage
  • Context-sensitive colorization
  • Customizable identation for JSON strings
  • Wide range of preset tokens ⇗ to extract and compose data as needed
  • Preset formats ⇗ combining useful tokens for an easy start
  • Possibility to add own format presets ⇗ for an easy reuse
  • Easily customizable tokens & formats
  • Override several console logging methods
  • In despite of everything it is possible to preformat ⇗ & postformat ⇗ data, e.g. to filter sensitive data

laabr screen


For installation use the npm ⇗:

$ npm install --save laabr

or clone the repository:

$ git clone



First you have to import the module:

const laabr = require('laabr');

Create hapi server

Afterwards create your hapi server if not already done:

const hapi = require('@hapi/hapi');
const server = hapi.server({
  port: 8888,
  host: 'localhost',


Finally register the plugin and set the correct options:

await server.register({
  plugin: laabr,
  options: {},


Take a look at several more examples ⇗.


const hapi = require('@hapi/hapi');
const laabr = require('laabr');

const server = hapi.server({ port: 3000 });

const options = {
  formats: { onPostStart: ':time :start :level :message' },
  tokens: { start:  () => '[start]' },
  indent: 0

    method: '*',
    path: '/response',
    handler() {
      return 'hello world';
    method: 'GET',
    path: '/error',
    handler () {
      throw new Error('foobar');

(async () => {
  try {
    await server.register({
      plugin: laabr,
    await server.start();
    console.log('Server started successfully');
  } catch (err) {

server.log('info', 'did you mean "foobar"?');


// (1) `log`
$ {"message":"did you mean \"foobar\"?","timestamp":1499352305938,"level":"info"}

// (2) `onPostStart`
$ 1499352305956 [start] info server started

// (3) `response` – calling `/response`
$ 1499352307927 GET /response 200 {} (25 ms)

// (4) `request-error` & `response` – calling `/error`
$ {"error":"foobar","timestamp":1499352320071,"level":"warn"}
$ 1499352320072 GET /error 500 {} (3 ms)

// (5) `onPostStop` – Pressing `Ctrl + C`
$ 1499352325077 info server stopped
