React UI State Component Library · 2026
Developed StateKitJS, an open-source React component library that simplifies handling common application states such as loading, empty, and error screens. The library provides customizable UI state components and a collection of modern animated loaders and spinners, enabling developers to build consistent, accessible, and visually polished interfaces with minimal effort. It includes responsive components, theme customization, comprehensive documentation, live demos, and an optimized developer experience for modern React applications.
The problem
Nested conditionals and one-off state components everywhere — loading, error, and empty checks make components hard to read, scatter logic across the app, and hurt maintainability.
if (loading) return <Spinner />;
if (error) return <ErrorView onRetry={refetch} />;
if (!users.length) return <EmptyState />;
return <UsersTable users={users} />;What it resolved
One declarative State component with a clear priority order: loading → error → empty → children. Cleaner, consistent, and easier to maintain.
import { State } from '@statekitjs/react';
<State
loading={loading}
error={error}
empty={users.length === 0}
onRetry={refetch}
>
<UsersTable users={users} />
</State>Highlights
