Script for parsing multiple sites and getting the basic Google Lighthouse indicators into a csv files.
Uses Google's lighthouse (https://github.com/GoogleChrome/lighthouse) to build a set of reports from the URL list you pass into the configuration file and writes the results into one file. This project is a fork of this project https://github.com/sahava/multisite-lighthouse
It's a Node.JS script, so you need Node / NPM installed on your machine.
After cloning the repo, run
npm install
to install the dependencies.
In config.json, edit the following fields:
| Field | Example | Description |
|---|---|---|
url |
["https://www.google.com/", "https://www.simoahava.com/about-simo-ahava/"] |
Array with list of fully formatted URLs to audit. It comes from the OCHA URLs to audit |
| Field | Example | Description |
|---|---|---|
lighthouseFlags |
{"output": "csv", "disableDeviceEmulation": true} |
List of flags to pass to lighthouse. Full list available here: https://github.com/GoogleChrome/lighthouse/blob/8f500e00243e07ef0a80b39334bedcc8ddc8d3d0/typings/externs.d.ts#L52 |
chromeFlags |
["--headless"] |
List of flags to pass to the Chrome launcher. Full list available here: https://peter.sh/experiments/chromium-command-line-switches/ |
writeTo |
"/users/sahava/Desktop/" |
The path where to write the reports - the tool will create the path if it doesn't exist. Remember the trailing slash in the end. |
Once you've set it up, you can run the audit tool with
node script.js
The process will be logged into the console.
The reports will be written in the format you chose for the output key in the configuration, and they will be written in the file you specified in the writeTo.
The fields of the output file are:
- Lighthouse version
- Timestamp of the execution
- URL being tested
- URL redirected
- Response code
- Performance Score (0 to 100)
- Accessibility Score (0 to 100)
- Best Practices (0 to 100)
- SEO Score (0 to 100)
- PWA Score (0 to 100)
If the script fails, you will have many Chrome processes running in your computer.
Run ASKKILL /IM chrome.exe /F in your command line on windows to kill all chrome pending processes (and existing ones! save your chrome work before doing this!).
- Read URLs directly from Google Sheet or published CSV from the Google Sheet
- Write the results into the specified folder
