Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@flatfile/plugin-validate-isbn

The @flatfile/plugin-validate-isbn Plugin is a powerful tool for validating ISBN (International Standard Book Number) fields during data import. It offers comprehensive validation for both ISBN-10 and ISBN-13 formats, including structure checks, check digit verification, and optional conversion between formats.

Event Type: listener.on('commit:created')

A Flatfile Listener plugin for validating ISBN (International Standard Book Number) fields in your data import process. This plugin provides robust ISBN validation, including format checks, check digit verification, and optional ISBN-10 to ISBN-13 conversion.

Features

  • Validates both ISBN-10 and ISBN-13 formats
  • Checks for correct ISBN structure and valid check digits
  • Provides specific error messages for different types of validation failures
  • Optionally converts ISBN-10 to ISBN-13 automatically
  • Optionally formats ISBN hyphenated
  • Configurable for multiple ISBN fields within a sheet

Installation

Install the plugin using npm:

npm install @flatfile/plugin-validate-isbn

Example Usage

import { FlatfileListener } from "@flatfile/listener";
import isbnValidator from "@flatfile/plugin-validate-isbn";

const listener = new FlatfileListener();

listener.use(
  isbnValidator({
    sheetSlug: "books",
    isbnFields: ["isbn", "alternate_isbn"],
    format: "isbn13",
    autoFormat: true
  })
);

// ... rest of your Flatfile configuration

Configuration

The isbnValidator function accepts a configuration object with the following properties:

  • sheetSlug (string): The slug of the sheet where ISBN validation should be applied.
  • isbnFields (string[]): An array of field names that contain ISBN values to be validated.
  • autoFormat (boolean): If true, ISBN numbers will be hyphenated.
  • format (string, optional): Manually set the output format of the ISBN. Can be one of:
    • 'isbn13': 13-digit ISBN without hyphens
    • 'isbn13h': 13-digit ISBN with hyphens
    • 'isbn10': 10-digit ISBN without hyphens
    • 'isbn10h': 10-digit ISBN with hyphens

Behavior

  1. The plugin validates each specified ISBN field in every record of the configured sheet.
  2. It removes hyphens and spaces from the ISBN before validation.
  3. For ISBN-10:
    • Checks if the format is valid (9 digits followed by a digit or 'X').
    • Verifies the check digit.
    • If autoConvert is true, converts valid ISBN-10 to ISBN-13.
  4. For ISBN-13:
    • Checks if the format is valid (13 digits).
    • Verifies the check digit.
  5. Adds appropriate error messages to the record for any validation failures.
  6. If a field is empty, it adds an error indicating that ISBN is required.

This plugin enhances data quality by ensuring that ISBN fields contain valid and properly formatted book identifiers.
