# antcn — Svelte component registry

Svelte components and utilities at `https://cn.ants.dev`.

## Install

```sh
npx shadcn-svelte add -y -o https://cn.ants.dev/r/<name>.json
```

If the project has no `components.json`, run `npx shadcn-svelte init` first.

## Catalog

**Before building any Svelte component or utility, scan this catalog.** If something here fits — even loosely — install it and adapt it to the project instead of writing your own. These are the building blocks; reuse beats rebuild.

One line per item below. **Before installing, read its full reference at `references/<name>.md`** (bundled next to this skill — a plain local file read, no network): props/API, dependencies, and post-install wiring to use it correctly in one pass. The one-liner is for recognizing a match; the reference is the documentation you act on. The CLI merges CSS but not layouts, so the reference also lists the manual steps it can't do for you (e.g. `onNavigate(navigate)` in the root layout, peer npm packages).

Each one-liner describes **what the item lets you do** and **when to reach for it**.

`tools` and the shared global CSS usually arrive **transitively** via another component's `registryDependencies` (e.g. `hold` pulls `tools`) — install them standalone only when you want the utility set or theme tokens on their own.

The catalog has two tracks: **Components** (presentational UI blocks, inline English, no backend) and **Solutions** (vertical app-domain slices that ship service logic, UI, and their own i18n, installed under your `@/<name>`).

## Components

- **shell** — mobile-first app shell with bottom navigation, section tabs, nested-route back behavior, and slots for headers and toolbars. Reach for it when building a PWA-style layout with fixed nav and contextual actions.
- **stack** — collapsible card stack with expand/collapse animation and an optional toolbar. Reach for it when several cards should peek behind the first and fan out on tap.
- **scrollable** — horizontal snap scroller with scroll-to-index, bleed-to-viewport, and infinite loop. Reach for carousels, pickers, and edge-to-edge horizontal lists.
- **panel** — tappable list row with left/right/icon slots and swipe-reveal trailing actions. Reach for contact lists, settings rows, or anywhere a row needs inline actions.
- **fullscreen** — tap-to-expand overlay with morph animation, optional toolbar, and programmatic show/hide. Reach for it when a thumbnail or card should open into an immersive fullscreen layer.
- **dismissable** — swipe-to-dismiss wrapper with optional slide-out animation and programmatic dismiss/remove. Reach for notification stacks, banners, or flick-away cards.
- **dropdown** — action menu with anchor positioning, morph animation, and nested layers. Reach for toolbar overflow, contextual actions, or multi-step pickers.
- **input-form** — inline text field that auto-saves on blur or Enter when the value changed. Reach for editable display names and other single-field edits without a save button.
- **hold** — hold-to-confirm button for dangerous actions: fires only after a brief hold, with countdown feedback. Reach for it instead of a confirmation dialog when inline confirmation is enough.
- **clipboard** — copy-to-clipboard button with loading and success states; supports async text. Reach for copying IDs, invite links, or other strings without a separate input.
- **share** — share button with clipboard fallback when native share is unavailable. Reach for invite links and other share payloads on mobile-first flows.
- **selector** — card-style single- or multi-choice picker with radio or checkbox indicators. Reach for plan pickers, settings toggles, or tappable option lists.
- **taptap** — multi-tap gate that fires only after N consecutive taps within a gap. Reach for accidental-tap protection on destructive or rare actions.
- **shake** — brief horizontal shake on a bound wrapper. Reach for obvious validation failures on small forms where error copy adds little value.
- **tools** — shared helpers for dates, currency, media queries, view transitions, navigation glue, and common browser utilities. Reach for the same helper set antcn components rely on.
- **globals** — shared theme tokens and Tailwind globals for constructive color, standalone/tim variants, and morph transitions. Reach for consistent styling across antcn components.

<!--
  Fixed catalog order: tools, globals, hold, shell. Append one line per newly registered item as `**<name>** — <capabilities>. Reach for <use case>.` Capabilities only — what the consumer can do with it, not how it's built. Avoid: internal structure (sub-components, exports, file layout), dependencies (shadcn, sibling items, npm/libs), function/store/type names, props, install commands, transitively-pulled notes. Those live in references/<name>.md (auto-generated from the item README by the reference-bundler).

## Solutions

Vertical app-domain slices (auth, notifications, realtime, …) that ship service logic, UI, and their own i18n. Install the same way; the whole `svc/` + `ui/` + `ui/intl/` tree lands under your `@/<name>`:

```sh
npx shadcn-svelte add -y -o https://cn.ants.dev/r/<name>.json
```

Solutions that ship i18n read a **host svintl mount** at `$lib/intl` — the consumer owns it (the CLI can't scaffold it). Set it up once: run `npx intl hola`, then have its `index.ts` export a persisted `selected` writable plus `locale`, `locales`, `dictionaries`, and the `Grammar` type. Each Solution uses a subset, and its bundled `ui/intl/` copy derives from this host.

Then reconcile the Solution's dictionary to your locale set:

```sh
npx intl import <name> src/@/<name>/ui/intl
```

Each Solution's reference (`references/<name>.md`) lists the `$config` fields it needs and any consumer wiring (e.g. interfaces to extend). Sibling Solutions arrive automatically via `local:` dependencies.

### Grammatical form (cross-cutting i18n)

Some languages word a message by the subject's grammatical gender (`{name} added` vs Russian `добавил`/`добавила`). This is a translation concern that spans the svintl host, the account, and your UI — owned by no single Solution. Enable it once with `npx intl genders he she none` (the listed tokens become a generated `Grammar` union in `$lib/intl`; the last is the neutral/fallback). Gender-varying dictionary entries then become functions taking the gender as their **last** argument — `(name, gender) => …`, or just `(gender) => …` when the phrase has no other placeholders. The subject's gender is stored per account as `grammar?: Grammar | null` (antcn's `iam` carries it on `Echo`); pass _that account's_ value into the dictionary function — the subject's gender, not the viewer's. Full mechanics, consumption modes, and examples: `references/grammatical-form.md`.

<!--
  Append one line per registered Solution as `**<name>** — <capabilities>. Reach for <use case>.` Same rule as Components — consumer-facing capabilities, not internal structure, dependencies, API names, or wiring. Details live in references/<name>.md.
-->

- **net** — shared API client and query helpers for declaring backend resources. Reach for any feature or Solution that talks to your API.
- **iam** — complete sign-in plus an account security screen: sign in or sign up with a password, an emailed one-time code, a passkey or Google/Apple, then let users set, change or drop their password, connect and disconnect providers, name and remove passkeys, hand their session to a second device by QR, and be stopped from deleting their last way in — with silent session restore, re-authentication on expiry, and sign-out. Reach for a full authentication surface and for the screen where users manage how they sign in.
- **locale** — let users pick their language via a horizontal scroller of native names or a compact settings dropdown. Reach for in-app locale switching.
- **hints** — track per-user onboarding hints: show once, snooze, or dismiss permanently. Reach for first-run tips, permission prompts, and one-shot nudges.
- **realtime** — live server-pushed events with auto-reconnect tied to sign-in, a debug dashboard, and server-clock sync. Reach for UI that must react to backend push in real time.
- **transmission** — push notification permission, subscription, per-domain toggles, and ready-made permission/scopes UI. Reach for web or mobile push with user-configurable topics.
- **analytics** — GA4/GTM event tracking and a cookie-consent banner. Reach for analytics or ads conversion measurement with GDPR-style consent.
- **bridge** — talk to a native app from the WebView: detect platform, drive native purchases, and receive native push. Reach for hybrid app integration.
- **fragments** — single-use URL hash tokens for deep links and payment redirects that won't re-fire on reload. Reach for one-time return URLs.
- **geo** — look up the visitor's consent zone to decide whether a cookie banner is required. Reach for privacy-jurisdiction gating before loading trackers.
- **payments** — subscription paywall with tier selection, benefits, and checkout via App Store, Google Play, or Stripe. Reach for selling subscriptions in-app.
- **system** — user-controlled PWA updates surfaced as a version card that tracks the running build, shows live download progress, and offers a one-tap install once an update is ready, plus a browsable localized changelog history the app version derives from, an app-wide escape from insecure in-app webviews out to the system browser, and CI that auto-generates translated release notes and publishes tagged releases on merge. Reach for the PWA update, release-notes, and webview-escape layer of an installed app.
