Empty State

The "nothing here yet" surface. Used wherever a list, table, or search returns zero rows AND the consumer can act on it (create the first item, adjust filters, link to docs). Empty states are first-class UX, not an afterthought — `LOADING_PHILOSOPHY` flags…

Preview

Empty State — live renderblocks-emptystate--default

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/empty-state.json
With the @interlace alias
npx shadcn@latest add @interlace/empty-state

Behavior

What this component does — the keyboard path, the measured colour, the text equivalent and the states it can be in. Every figure below is read out of the test or the source that enforces it by scripts/build-behavior-map.mjs, so nothing here can outlive the gate that keeps it true.

Every semantic colour pair this component's own source uses, measured against the shipped hexes in all 4 theme × scheme combinations. The tightest is muted-foreground on background at 7.82:1 (harbor · light), against a floor of 4.5:1.

Measured WCAG contrast ratios per token pair and theme
PairinterlacelightinterlacedarkharborlightharbordarkFloor
muted-foreground on backgroundsecondary copy9.41:111.32:17.82:19.52:14.5:1SC 1.4.3
muted-foreground on cardsecondary copy in a card9.41:110.48:18.25:18.64:14.5:1SC 1.4.3

Text pairs are held to 4.5:1 (WCAG 2.2 SC 1.4.3); borders, rings and chart axes to 3:1 (SC 1.4.11 non-text). Bold is the worst cell in the row — the one a brand fork has to keep an eye on.

Where it renders, how narrow it survives, and whether its lines are inside the coverage gate — three answers a consumer needs before the paste, not after the bug.

Render boundary
server component

Renders during SSR / RSC with no hydration cost. It can be imported from a server component without pulling the page into the client.

Minimum viewport
MIN_VIEWPORT = 320

Declared, not assumed. Below 320 CSS px the preflight contract draws a dev-mode outline — how to switch it on.

Coverage gate
not in the gate

The 100% gate currently covers src/charts/**/*.{ts,tsx} and src/lib/**/*.{ts,tsx} and src/primitives/{button-variants,data-state-model,meter-scale,skeleton-variants}.ts and src/primitives/{alert,aspect-ratio,avatar,badge,box,breadcrumb,button,callout,card,checkbox,container,data-state,focus-ring,grade-badge,grid,input,label,meter,pagination,published-date,reading-time,section,section-boundary,separator,skip-link,stack,stat-strip,tag,textarea,typography,visually-hidden}.tsx. This file is outside it — the glob widens in phase 7.2.

History

This component is at v1.2.0, 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.

Import

2 named exports — pull the parts you need.

Public API
import { EmptyState, MIN_VIEWPORT } from '@/components/ui/patterns/empty-state';

Anatomy

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

EmptyState                       (block — data-min-viewport=320)
    ├─ {icon}                      (optional — usually a lucide outline icon)
    ├─ Typography variant=h4       (title)
    ├─ Typography variant=body     (description)
    └─ {actions}                   (optional CTA cluster, often a Button)

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.

EmptyStateProps

Also accepts every <div> attribute.

PropTypeDescription
title*React.ReactNodeThe headline — keep it factual and short. e.g. "No rules match these filters".
descriptionReact.ReactNodeSupporting copy — describe how the consumer can change the result.
iconReact.ReactNodeOptional icon slot — pass a lucide-react icon element.
actionsReact.ReactNodeOptional action slot — typically a primary Button + a quiet text link.

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
None — semantics come from the element or the Base UI primitive rather than hand-written ARIA.

Examples

2 more states from the same story file.

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<'div'> & EmptyStateProps`
R6data-slot on root`data-slot="empty-state"`
R7className merged + ...rest`cn(BASE, className)` + `{...props}`
R8No isXxx; enums for variantsn/a — no variants on this block
R10Composition seam`icon` + `actions` slots
R14Declares min viewport`data-min-viewport={String(MIN_VIEWPORT)}` + exported const
R18Tailwind onlyZero inline style
R19Tokens onlybg/border/text from semantic tokens
R25Server componentNo hooks → no `'use client'`

Minimum viewport

This primitive declares MIN_VIEWPORT = 320 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.
