@haverstack/eleventy

An Eleventy plugin that builds a static site from a Haverstack stack. Records are the content source; there are no content files on disk.

Status: Early development, but the whole pipeline works — load, resolve, asset staging, markdown, emit (pages, collections, feeds, sitemap), built-in templates that a site can override with its own, and the check / publish commands. docs/design.md covers how it works and why.

Usage

import { haverstack } from '@haverstack/eleventy';
import { LocalAdapter } from '@haverstack/adapter-local';
import { Stack } from '@haverstack/core';

export default async function (eleventyConfig) {
  const stack = await Stack.create(await LocalAdapter.open({ path: './stack.db' }));

  eleventyConfig.addPlugin(haverstack, {
    stack,
    site: 'personal',
    assetDir: '_stack-assets',
    slugStrategy: 'title',
  });
}

The plugin takes a Stack, not a URL — so a build can run against a remote server (APIAdapter), a local SQLite file (LocalAdapter), or an in-memory stack (MemoryAdapter, for tests). Whoever constructs the stack has already dealt with auth; the plugin never handles credentials and never writes.

Out of the box it renders a legible site with its built-in templates. The pages are ordinary Eleventy pages: transforms and global data apply, and every listed page/member carries tags (haverstack, its type, its tag associations) and eleventyNavigation, so collections.*, navigation plugins, and anything reading collections.all see them.

To use your own layouts, map template names to files in your _includes:

eleventyConfig.addPlugin(haverstack, {
  stack,
  site: 'personal',
  templates: { base: 'layouts/base', listing: 'layouts/index', article: 'layouts/longform' },
});

A mapped page emits its content fragment ({{ content }}) plus record, meta, url, canonical, body / bodyRaw, collection, and the haverstack globals; the layout does the rest and may chain to another. base catches any unmapped name; anything still unmapped keeps the built-in render. haverstack-eleventy eject writes a starter haverstack-base.njk to get going. Other options: eleventyCollections: false for full isolation, pageData: (ctx) => ({…}) to compute extra template data per record.

Types

Consumes the commons publishing types — site@1, page@1, article@1, post@1, photo@1, bookmark@1 — plus _entity@1 and _attachment@1.

Owns two sidecar types, minted under org.haverstack.eleventy:

Type	Role
org.haverstack.eleventy/page-meta@1	Per-record, per-site overrides: slug, template, order, hidden, draft. Every field optional.
org.haverstack.eleventy/menu@1	A named, ordered navigation menu belonging to one site.

defineEleventyTypes(stack) registers the whole set. It is idempotent and safe to call on every build; under a non-owner credential it tolerates types that already exist.

Commands

haverstack-eleventy check     load + resolve, report structural problems, write nothing
haverstack-eleventy publish   stamp article.url / post.url with the canonical location
haverstack-eleventy eject     write a starter haverstack-base layout into _includes

check and publish read the stack from a config module (--config, default ./haverstack.config.mjs) that default-exports a Stack, a { stack, site? }, or a function returning one — the same place a project builds the stack for eleventy.config.js. --site <handle> overrides the config's site.

check is read-only and safe against production data; it exits non-zero when it finds a build failure (a path collision, conflicting sidecars). publish writes — run it deliberately after a good build; --dry-run shows what it would stamp.
