README

This package provide a php interface for Google Lighthouse.

Here's an example that will perform the default Lighthouse audits and store the result in report.json (You can use the Lighthouse Viewer to open the report):

use Dzava\Lighthouse\Lighthouse;

(new Lighthouse())
    ->setOutput('report.json')
    ->accessibility()
    ->bestPractices()
    ->performance()
    ->pwa()
    ->seo()
    ->audit('http://example.com');

Output

The setOutput method accepts a second argument that can be used to specify the format (json,html). If the format argument is missing then the file extension will be used to determine the output format. If the file extension does not specify an accepted format, then json will be used.

You can output both the json and html reports by passing an array as the second argument. For the example the following code will create two reports example.report.html and example.report.json.

use Dzava\Lighthouse\Lighthouse;

(new Lighthouse())
    ->setOutput('example', ['html', 'json'])
    ->performance()
    ->audit('http://example.com');

Using a custom config

You can provide your own configuration file using the withConfig method.

use Dzava\Lighthouse\Lighthouse;

(new Lighthouse())
    ->withConfig('./my-config.js')
    ->audit('http://example.com');

Customizing node and Lighthouse paths

If you need to manually set these paths, you can do this by calling the setNodeBinary and setLighthousePath methods.

use Dzava\Lighthouse\Lighthouse;

(new Lighthouse())
    ->setNodeBinary('/usr/bin/node')
    ->setLighthousePath('./lighthouse.js')
    ->audit('http://example.com');

Passing flags to Chrome

Use the setChromeFlags method to pass any flags to the Chrome instance.

use Dzava\Lighthouse\Lighthouse;

(new Lighthouse())
    // these are the default flags used
    ->setChromeFlags(['--headless', '--disable-gpu', '--no-sandbox'])
    ->audit('http://example.com');
