Saving a web page from PhantomJS as a PDF

This recipe goes into more detail about webpage.render, and it shows how to generate PDFs. We also introduce the paperSize property of webpage instances and how to control the sizes of the pages in the PDF output.

Getting ready

To run this recipe, we will need a script that accesses a web page. We also need write permissions to the filesystem in the script's working directory.

The script in this recipe is available in the downloadable code repository as recipe05.js under chapter07. If we run the provided example script, we must change to the root directory for the book's sample code.

Lastly, the script in this recipe runs against the demo site that is included with the cookbook's sample code repository. To run the demo site, we must have Node.js installed. In a separate terminal, change to the phantomjs-sandbox directory (in the sample code's directory), and start the app with the following command:

node app.js
