Run chrome lighthouse's audit from command line

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 ?

Solution

  • Google Lighthouse can be ran using the command line. To run it from the command line, you must first install:

    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.
