Installation

Usage

Basic Setup

Add the plugin to your .eleventy.js configuration:

import kvCollectionsPlugin from "eleventy-plugin-cloudflare-kv";

export default function (eleventyConfig) {
  eleventyConfig.addPlugin(kvCollectionsPlugin, {
    metadata: {
      permalink: (itemData, itemKey, collectionName) => {
        return `/${collectionName}/${itemData.slug || itemKey}/`;
      }
    }
  });
}

Configuration Options

Option	Type	Required	Description
metadata	Object	No	Additional metadata to add to each item
accountId	String	No	Environment variable name for Cloudflare Account ID (default: CLOUDFLARE_ACCOUNT_ID)
namespaceId	String	No	Environment variable name for KV Namespace ID (default: CLOUDFLARE_KV_NS_ID)
cloudflareAPIToken	String	No	Environment variable name for API Token (default: CLOUDFLARE_API_TOKEN)
quiet	Boolean	No	Suppress console output except errors (default: false)

Environment Variables

Set these environment variables in your build environment:

CLOUDFLARE_ACCOUNT_ID=your-account-id
CLOUDFLARE_KV_NS_ID=your-namespace-id
CLOUDFLARE_API_TOKEN=your-api-token

Or configure custom variable names:

eleventyConfig.addPlugin(kvCollectionsPlugin, {
  accountId: "MY_ACCOUNT_ID",
  namespaceId: "MY_KV_NAMESPACE",
  cloudflareAPIToken: "MY_API_TOKEN",
  metadata: {
    permalink: (itemData) => `/posts/${itemData.slug}/`
  }
});

KV Key Structure

The plugin organizes content into collections based on your KV key structure:

• posts/hello-world → Collection: posts, Item key: hello-world
• pages/about → Collection: pages, Item key: about
• standalone → Collection: none, Item key: standalone

Content Format

Store your content in KV with front matter:

---
title: "Hello World"
date: 2024-01-01
slug: "hello-world"
tags: ["post", "greeting"]
---

# Hello World

This is my first post stored in Cloudflare KV!

Advanced Configuration

eleventyConfig.addPlugin(kvCollectionsPlugin, {
  metadata: {
    permalink: (itemData, itemKey, collectionName) => {
      if (!itemData.permalink) {
        if (!itemData.title || !itemData.date) {
          throw new Error(`Unable to generate permalink for item: ${itemKey}`);
        }
        const date = new Date(itemData.date);
        const year = date.getFullYear();
        const slug = itemData.slug || itemKey;
        return `/${collectionName}/${year}/${slug}/`;
      }
      return itemData.permalink;
    },
    layout: "post.njk",
    collection: (itemData, itemKey, collectionName) => collectionName
  },
  quiet: true
});
