Scheduled generation of screenshot PDFs of external sites

Overview

The generate_pdf plugin allows you to capture the screen of a specified URL and save the output as a PDF or an image. You can call it anywhere Smarty syntax is allowed, such as in Custom function or Batch processing.

In this tutorial, we will create a batch process that takes a daily screenshot of an external site and saves it as a PDF in Kuroco.

Before you start

To use the plugin, you need to first integrate Firebase into your Kuroco admin panel.
For a detailed guide on how to perform this integration, see Tutorial: Cloud storage integration with Firebase.

Batch process creation

In the sidebar menu, select [Operation] -> [Batch process].

Click [Add] in the upper right corner.

Create a batch process with the following settings:

Field	Value
Title	Daily screenshot taker
Identifier	daily_capture
Batch	Every day, 00:00
Process	(Paste the code below into this field.)

{assign var=date value=$smarty.now|date_format:'%Y%m%d'}
{assign var=path value='files/g/private/sample_'|cat:$date|cat:'.pdf'}
{generate_pdf url='https://www.diverta.co.jp' path=$path}

Click [Add] to save the process.

Batch process verification

In this example, the batch process will run at midnight every day, and the output PDF will be saved in KurocoFiles.

Alternatively, you can click [Run now] next to the process title to run it immediately.

You should see a success message at the top of the screen.

Next, check if the output file has been saved correctly.

Click [File manager] in the side menu.

The file should appear in the GCS(Private) folder.

tip

It may take up to several minutes for the file to be generated.
