Top Svelte UI Libraries

Storybook is a development environment for UI components, allowing developers to build, test, and document components in isolation.

Code Example

import Button from './Button';

export default {
  component: Button,
  title: 'Components/Button',
};

export const Primary = () => <Button primary>Click me</Button>;

Pros

• Offers a comprehensive ecosystem for component development, testing, and documentation, unlike more focused libraries like TanStack/table or TanStack/virtual.
• Supports multiple frontend frameworks (React, Vue, Angular, Svelte), making it more versatile than framework-specific solutions like sveltejs/svelte or chakra-ui/zag.
• Provides powerful addons for accessibility testing, responsive design, and more, which are not available in simpler UI libraries like skeletonlabs/skeleton or konstaui/konsta.

Cons

• Has a steeper learning curve compared to lightweight alternatives like huntabyte/shadcn-svelte or melt-ui/melt-ui.
• Requires more setup and configuration than simpler solutions like fwouts/previewjs or rgossiaux/svelte-headlessui.
• Can be overkill for smaller projects or teams that don't need its full range of features, unlike more focused tools like vidstack/player or huggingface/chat-ui.

Svelte is a modern JavaScript framework for building user interfaces with a focus on simplicity and performance.

Code Example

<script>
  let count = 0;
</script>

<button on:click={() => count++}>Clicks: {count}</button>

Pros

• Svelte offers a simpler and more intuitive syntax compared to many other frameworks.
• It compiles to vanilla JavaScript, resulting in smaller bundle sizes and better performance.
• Svelte has a gentler learning curve, making it accessible to beginners.

Cons

• Svelte has a smaller ecosystem and fewer third-party components compared to React or Vue.
• It may have limited tooling support in some areas compared to more established frameworks.
• Svelte's compile-time approach can make certain dynamic runtime behaviors more challenging to implement.

TanStack Table is a headless UI library for building powerful tables and datagrids in React, Vue, and Solid.

Code Example

import { useTable } from '@tanstack/react-table'

const table = useTable({ columns, data })
return <table {...table.getTableProps()}>{/* ... */}</table>

Pros

• Offers advanced features like sorting, filtering, and pagination out of the box
• Framework-agnostic, supporting React, Vue, and Solid
• Highly customizable and extensible with a plugin system

Cons

• Steeper learning curve compared to simpler table libraries
• Requires more setup and configuration than some UI-focused alternatives
• Not as visually polished out of the box as some component libraries

huggingface/chat-ui is an open-source chat interface for large language models, designed to be easily customizable and deployable.

Pros

• Specifically tailored for AI chat applications, unlike more general UI libraries like Svelte or Storybook
• Integrates seamlessly with Hugging Face's ecosystem of AI models and tools
• Provides a ready-to-use chat interface, reducing development time compared to building from scratch

Cons

• Less flexible for non-chat applications compared to general-purpose UI libraries like Svelte or Chakra UI
• May have a steeper learning curve for developers not familiar with Hugging Face's ecosystem
• Potentially less customizable than building a chat interface from scratch using component libraries like shadcn-svelte or Skeleton

huntabyte/shadcn-svelte is a port of the popular shadcn/ui components for Svelte, providing accessible and customizable UI components.

Code Example

<script>
  import { Button } from "$lib/components/ui/button";
</script>

<Button variant="outline">Click me</Button>

Pros

• Offers a comprehensive set of pre-built, accessible UI components specifically for Svelte projects
• Provides a consistent design system that can be easily customized to match brand guidelines
• Leverages the power of Svelte's reactivity and component model for efficient rendering

Cons

• As a port of shadcn/ui, it may lag behind the original React version in terms of new features or updates
• Has a smaller community and ecosystem compared to more established UI libraries like Chakra UI or Material UI
• May require additional configuration and setup compared to some all-in-one UI frameworks for Svelte
