How to use it ?

Run with CLI

Prerequisites

  • Install Chrome or Chromium
  • Install Lighthouse
npm install -g lighthouse
  • Install this package
npm install -g lighthouse-orchestrator

Run

# generate default configuration
lightkeeper --init-config

# run it
lightkeeper

Available arguments :

  • --config-dir : Directory containing your config files, default is current directory. See below for configuration details.

  • --data-dir : Directory for output storage, defaults to ./data. See below for output details.

  • --init-config : Writes default configuration to "config-dir" path so you can adapt them to your needs.

  • --init-profiles : Writes default lighthouse profiles to "config-dir" path so you can adapt them to your needs.

Run with Docker

Prerequisites

git clone git@github.com:GGracieux/lighthouse-orchestrator.git
  • build dockerfile
docker build -t lightkeeper .
  • Create a docker-compose.yml specifying config-dir and data-dir folders (see below for configuration and output details). For example :
version: '3.2'
services:
  lightkeeper:
    image: lightkeeper
    volumes:
      - /tmp/conf:/lightkeeper/conf:rw
      - /tmp/data:/lightkeeper/data:rw
    ports:
      - 8086:80

Run

docker-compose up

Configuration

All configuration files must be located under the config-dir passed as command argument. A set of example configurations are available under /examples :

jobs.json

This file defines the jobs to run with lighthouse. Each job must specify the following properties :

  • url : the url to run
  • profiles : the list of profiles to run the test with, see below for profile configuration
  • cron : the frequency at wich test should be run. Notation is like cron with seconds granularity.

Additional properties can be added, they can be writent to result log according to result log configuration.

If your config-dir does not have a jobs.json file, lightkeeper uses it's default (see /default-conf/jobs.json)

For example the following jobs.json file runs :

        {
            "url":"https://www.example.com",
            "profiles":[ "mobile"],
            "cron": "1 */30 * * * *"
        },
        {
            "url":"https://www.google.com",
            "profiles":[ "mobile", "desktop"],
            "cron": "1 1 */1 * * *"
        }

lightkeeper.json

This file defines the general execution parameters of lighkeeper. Lightkeeper loads it's default configuration (see /default-conf/lightkeeper.json) and then overloads it with your custom lightkeeper.json file located under config-dir folder.

The following lightkeeper.json file is the default configuration :

{
    "reports":{
        "formats": ["html"],
        "retentionDays": 7
    },

    "logs":{
        "lightkeeper":{

profile.xxxxx.json

The profile.xxxxx.json files are lighthouse configuration files. The xxxxx filename part defines the profile name which you can use in jobs.json.

You can add as many profile as you want based on lighthouse configuration format

Lightkeeper comes with two default profiles, mobile and desktop, they are identical to lr-desktop-config.js and lr-mobile-config.js

You can add new profiles by writing profile.xxxx.json files under config-dir. You can overwrite default mobile and desktop files by writing profile.mobile.json and profile.desktop.json under config-dir.

Outputs

Every data produced by lightkeeper is stored under the data-dir passed as command argument. According to lightkeeper.json, the data-dir folder can be exposed through http.
