Requirements

• TYPO3 CMS 9.5+
• Google Account

Installation & Configuration

The extension just needs to be installed as any other extension. To make it work, you need a Google account and activate the PageSpeed service. After successfully activating the PageSpeed service you need to set the key in the configuration in EM and deactivate the demo mode.

Enable PageSpeed Service

1. Open console.developers.google.com and create a new project.
2. Open the project and switch to APIs and auth > APIs, select PageSpeed Insights API and Activate the API.
3. Switch to Credentials and click the button Create new key for public API access.
4. Create either a Server key or a Browser key*.
5. Test the access by using cUrl on the server where you want to use the extension by calling the command curl 'https://www.googleapis.com/pagespeedonline/v2/runPagespeed?strategy=desktop&url=http://www.bbc.co.uk/&key=AIzaSyA2rQEy7UyQz-9D1-7bnmw1jzSo0FmobYM'. (If you get a Bad request, just wait a few minutes to get the key deployed on all Google servers)

Preview Domain

If you need to use a different domain in the frontend or no sys domain record is available, you can use the following configuration inside your PageTsConfig:

TCEMAIN.previewDomain = localhost/sites/t3/master

Avoid error "require_once(Net/URL2.php)"

If you see an exception about the file Net/URL2.php not found, please open the file typo3/contrib/vendor/pear/http_request2/HTTP/Request2.php and remove the require_once statement in line 24. This bug will be gone soon.

Technical background

A little bit technical information for the ones who are interested in:

The API is described in detail at developers.google.com/speed/docs/insights/v2/reference/pagespeedapi/runpagespeed and it is very simple to test by just using curl:

# Desktop
curl 'https://www.googleapis.com/pagespeedonline/v2/runPagespeed?strategy=desktop&screenshot=true&url=http://www.typo3.org&key=<your_key>'
# Mobile
curl 'https://www.googleapis.com/pagespeedonline/v2/runPagespeed?strategy=mobile&screenshot=true&url=http://www.typo3.org&key=<your_key'
