问题
I would like to write a script which run (from the chrome's binary) its lighthouse's audit with a url given.
I didn't manage to find how to do it, but since there is even a chrome extension doing I assume it should be feasible right ?

Google Lighthouse can be ran using the command line. To run it from the command line, you must first install:
- Google Chrome for Desktop
- Node.js v6 or later.
To install the Lighthouse CLI, open a command line and type the following command:
npm install -g lighthouse
To run an audit with Lighthouse, type:
lighthouse https://example.com
By default, Lighthouse writes the report to an HTML file. You can control the output format by passing flags.
You will notice that a Chrome window is opened every time you run Lighthouse. If you don't want a window to be opened, you can run it in headless mode:
lighthouse https://example.com/ --chrome-flags="--headless"
For the complete list of options, type:
lighthouse --help
Take a look at the Lighthouse source code repository for additional documentation and examples.

You can use/test via npx:
npm i npx -g
Then, directly run from your terminal without using a package.json created or installing globally & without opening a chrome browser instance:
npx lighthouse <URL> --only-categories="performance,seo,Accessibility" --chrome-flags="--headless"
