@comwit/state

React / Next.js state management for vibe coding.

Battle-tested across 1,000+ projects on comwit.io — a Claude Code-powered vibe coding platform from Korea. Sponsored by burrr.ai.

Renamed from comwit. As of v2.0.0 this library is published as @comwit/state. The API is unchanged — only the package name and import specifier changed. See the migration notes.

Install

npm i @comwit/state

Pass the URL to Claude Code. It handles the rest.

Durable on-demand queries (2.2 beta)

const todos = local.collection<Todo>({ key: 'todos', version: 1 })

const todo = model({
  list: local.query<Todo[], TodoFilter>({
    source: todos,
    initialData: [],
    queryFn: api.todo.list,
  }),
  detail: local<Todo | null, { id: string }>({
    source: todos,
    initialData: null,
  }),
})

local() restores an exact IndexedDB view without making an API request, which fits server-owned SEO details. local.query() and local.infinite() add background server revalidation while keeping the existing .load(), .query(), .refetch(), .set(), and optimistic mutation interfaces.
