Svelte (Experimental) ​

Wave B foundation adapter. storeBind only. No Svelte component library for Sometic button / input / form / overlay yet.

Prefer React, Vue, or Elements for production UI.

When to use ​

  • Svelte 5 app that needs an Sometic-backed store with a Svelte-friendly subscribe / set / update shape.
  • You will build UI in .svelte files or host Elements.

When not to use ​

  • You expect @sometic/svelte/button components. Not shipped.
  • You need Wave A completeness → use React, Vue, or Elements.

Installation ​

pnpm
pnpm add @sometic/svelte @sometic/store
npm
npm install @sometic/svelte @sometic/store
yarn
yarn add @sometic/svelte @sometic/store
bun
bun add @sometic/svelte @sometic/store

API surface ​

ts
import {
    createSvelteStoreBind,
    svelteAdapterCapabilities,
    type SvelteStoreBind,
} from "@sometic/svelte";
MemberRole
storeUnderlying Sometic store
subscribe(run)Svelte store-compatible subscribe
set(value)Replace state
update(updater)Functional update
dispose()Tear down

subscribe follows the Svelte store contract closely enough to use with auto-subscription ($) patterns when you treat the bind as a store-like object. Always dispose() when the owner unmounts.

Usage ​

ts
import { createSvelteStoreBind } from "@sometic/svelte";

const bind = createSvelteStoreBind({ count: 0 });

const stop = bind.subscribe((state) => {
    console.log(state.count);
});

bind.update((state) => ({ count: state.count + 1 }));

stop();
bind.dispose();

Limits (honest) ​

  • Capability list is exactly ["storeBind"].
  • No form / overlay / auth / HTTP Svelte adapters.
  • CLI does not scaffold framework: svelte.
  • Deferred catalogs remain deferred even if you host Elements.

FAQ ​

Is $bind officially supported? ​

The bind exposes subscribe / set / update. Treat auto-subscription as a convenience on top of that contract; verify in your Svelte 5 version. Dispose explicitly.

Can I ship production UI with only this package? ​

No. Pair with Elements or a Wave A framework, or own the components yourself.
