Penthouse Service

A service to create criticalpath css using penthouse.

Run service locally

Install all dependencies using npm install. Afterwards you can start the service using:

npm run service

This will start a server at port 3000.

Running service with docker

The released images are available on docker hub. The version schema follows the installed version of penthouse.

Release new service version with docker

Create a docker image of the penthouse-service using:

docker build -t moccu/penthouse-service:latest .

If you want to create a new release on Docker Hub, you need to tag and push the previous built image:

Hint: remember to update the version in the package.json!

docker tag moccu/penthouse-service:latest moccu/penthouse-service:<version>
docker push moccu/penthouse-service:<version>

Once the image is ready start the service using the following command.

• <portnumber> is the port which you want to use for the service
• pass --init to prevent chrome from creating zombie processes ([chrome] <defunct>):

docker run -p <portnumber>:3000 --init moccu/penthouse-service:latest

Usage

Penthouse needs an URL and a CSS file to extract the critical css from. Pass this data via GET-params to the service by requesting the endpoint as followed: http://localhost:3000/?url=<website-url>&css=<css-url>.

For example: http://localhost:3000/?url=http://example.com/&css=http://example.com/css/styles.css

Options

Pass optional penthouse configuration by adding them as GET-parameter. Multiple params with same name will be interpreted as type array.

For example: http://localhost:3000/?url=http://example.com/&css=http://example.com/css/styles.css&width=720&propertiesToRemove=(.*)transition(.*)&propertiesToRemove=cursor&forceInclude=.footer
