Overview

The node named "Hardcover" integrates with the Hardcover API to perform various operations related to books, authors, editions, publishers, series, and user data. Specifically, for the Book resource with the Search For Books operation, it allows users to search for books based on a query string and optional pagination parameters.

This node is beneficial in scenarios where you want to programmatically retrieve book information from the Hardcover database, such as building book recommendation systems, cataloging books, or integrating book search functionality into applications.

Example use cases:

  • Searching for books by title, author, or keywords.
  • Retrieving paginated lists of books matching specific criteria.
  • Integrating book search results into content management systems or websites.

Properties

Name Meaning
Query The search term or keywords used to find books. This is a required string input.
Advanced (collection) Optional additional parameters to refine the search:
- Per Page Number of results to return per page (default 25).
- Page The page number of results to retrieve (default 1).

Output

The node outputs an array of JSON objects, each representing the result of the search operation for each input item. Each JSON object contains the data returned by the Hardcover API for the book search query.

The exact structure of the JSON depends on the Hardcover API response but typically includes details about books such as titles, authors, publication info, and other metadata.

No binary data output is indicated in the source code.

Dependencies

  • Requires an active connection to the Hardcover API via an API key credential configured in n8n.
  • The node depends on internal helper functions (executeSearchOperation and executeResourceOperation) to interact with the API.
  • Proper API credentials must be set up in n8n for authentication.

Troubleshooting

  • Common issues:

    • Missing or invalid API credentials will cause authentication failures.
    • Providing an empty or invalid query string may result in no results or errors.
    • Pagination parameters out of range might lead to empty responses.

  • Error handling:

    • If an error occurs during execution, the node either throws the error or, if "Continue On Fail" is enabled, returns an error message in the output JSON under the error field.

  • Resolution tips:

    • Ensure the API key credential is correctly configured and valid.
    • Verify that the query string is not empty and properly formatted.
    • Adjust pagination parameters within reasonable limits.
