Overview

The node provides utilities for working with PDF files, specifically including an operation to count the number of pages in a PDF document. This is useful when you need to quickly determine the length of a PDF without downloading or manually inspecting it. Common scenarios include validating document size before processing, generating reports about document contents, or automating workflows that depend on page counts.

For example, you might use this node to:

• Automatically check if a PDF invoice has more than a certain number of pages before sending it for approval.
• Count pages in a batch of PDFs to generate metadata for a document management system.
• Validate uploaded PDFs in a form submission process by checking their page count.

Properties

The user must provide either a publicly accessible URL pointing to the PDF or the binary content of the PDF as a buffer string.

Output

The node outputs JSON data containing the count of pages in the provided PDF document. The exact structure is not shown in the source, but typically it would be something like:

{
  "pageCount": 10
}

This output allows downstream nodes to access the number of pages and make decisions or further processing based on that value.

No binary data output is indicated for this operation.

Dependencies

• Requires an API key credential for authentication to the external service at https://prod.0codekit.com.
• The node sends a POST request to the /pdf/count endpoint with either the PDF URL or buffer in the request body.
• No other external dependencies are indicated.

Troubleshooting

• Common issues:

  • Providing an invalid or inaccessible PDF URL will likely cause errors or zero page count results.
  • Supplying malformed or incorrect binary buffer data may result in failure to parse the PDF.
  • Missing or invalid API credentials will prevent the node from authenticating with the external service.

• Error messages:

  • Authentication errors indicate problems with the API key; ensure the correct credential is configured.
  • Network or timeout errors suggest connectivity issues to the external API endpoint.
  • Parsing errors imply the PDF data is corrupted or unsupported.

To resolve these, verify the input PDF source, confirm API credentials, and ensure network connectivity.
