Rendered from the story the storybook (a11y) CI gate runs axe against — the preview can't show something that hasn't been verified.

Install

Two equivalent paths — the URL works in any shadcn-CLI setup; the alias works once you've registered @interlace in your components.json.

Via shadcn URL
npx shadcn@latest add https://ds.interlace.tools/r/related-posts.json
With the @interlace alias
npx shadcn@latest add @interlace/related-posts

History

This component is at v1.3.0, first shipped in @interlace/ui 1.0.0. The version is stamped as a banner into the file the install writes, so the copy in your tree says which one you have — compare it with the number above before deciding whether to re-run the install.

@interlace/ui 1.1.01 entry

Import

2 named exports — pull the parts you need.

Public API
import { MIN_VIEWPORT, RelatedPosts } from '@/components/ui/patterns/related-posts';

Anatomy

Extracted from the primitive's JSDoc header. The source is the only documentation that can't drift.

RelatedPosts                       (section — data-min-viewport=480)
    ├─ Typography h3                 (title — "Related posts" by default)
    └─ Grid cols=1 md:2 lg:3 gap=md  (one ArticleCard per post)
          └─ ArticleCard

API reference

Parsed from the type declarations in the source — the same file the install writes into your tree, so this table can't drift from the component you get.

RelatedPostsProps

Also accepts every <section> attribute.

PropTypeDescription
titleReact.ReactNodeSection heading. Default: `"Related posts"`.
postsRelatedPost[]Posts to render. One ArticleCard per entry, in order. Optional when `loading={true}`.
loadingbooleanWhen true, render a grid of `<Skeleton variant="article-card" />` placeholders (count derived from `loadingCount`, default 3) so the page reserves the eventual grid footprint while data loads.
loadingCountnumberHow many skeleton cards to render when `loading={true}`. Default 3.

Skeleton

Pass loading and the component renders a shape-matched <Skeleton /> in its own place — same box, so nothing reflows when the data lands. Below is the same story with loading={true}.

Usage

Accessibility

Every story for this component is rendered headlessly and checked with axe-core (wcag2aa, wcag22aa, best-practice, ACT) on every PR. That gate has no continue-on-error, so what ships has zero known violations.

What follows is what static analysis can see. Axe cannot press a key and never sees an overlay open, so the operable-without-a-mouse claim lives in Behavior instead, where the keyboard path is replayed step by step.

Focus + keyboard behaviour
Native element semantics — no interaction layer to get wrong.
Focus ring (WCAG 2.2 SC 2.4.13)
Not focusable — no focus indicator required.
Reduced motion
No animation to gate.
ARIA in the source
  • aria-busy
  • aria-label

R-rule compliance

Every primitive in @interlace/ui models to the portable 26-rule floor enforced by the componentApi ESLint preset. The cells below pin exactly where each rule applies in this file.

RuleConceptWhere
R4Extends native el`React.ComponentProps<'section'> & RelatedPostsProps`
R6data-slot on root`data-slot="related-posts"`
R7className merged + ...rest`cn(BASE, className)` + `{...props}`

Minimum viewport

This primitive declares MIN_VIEWPORT = 480 CSS px (DESIGN_PRINCIPLES #14). When mounted in a container narrower than this, the preflight contract draws a dev-mode outline so the regression is visible during local development.

Opt-in to the dev-mode warning
<body data-interlace-dev>...</body>

Add the data-interlace-dev attribute to the body in development builds only — preflight then outlines any primitive whose container is below its declared data-min-viewport.

 * grid of ArticleCards: one column on phones, two from `md` up, three from

 * The block is intentionally a pure composition over `ArticleCard` (the
 * stacked grid tile): every metric this block could surface (date, kicker, summary)
 * already lives on ArticleCard's props, so this file owns ONLY the heading,
 * the grid, and the field mapping from the editorial-friendly post shape
