Top Svelte UI Libraries

Storybook is an open-source tool for building UI components and pages in isolation, making it easier to develop, test, and document UI components.

Code Example

import { Button } from './Button';

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

Pros

• Storybook offers a comprehensive ecosystem for UI development, testing, and documentation, unlike more focused libraries like TanStack/table or vidstack/player.
• It supports multiple frontend frameworks, making it more versatile than Svelte-specific tools like huntabyte/shadcn-svelte or melt-ui/melt-ui.
• Storybook provides a rich set of addons and integrations, offering more functionality than simpler UI libraries like konstaui/konsta or illright/attractions.

Cons

• Storybook has a steeper learning curve compared to lightweight alternatives like fwouts/previewjs or agmmnn/tauri-ui.
• It can be overkill for smaller projects or teams, unlike more focused tools like chakra-ui/zag or huggingface/chat-ui.
• Storybook requires additional setup and configuration, which may be unnecessary for projects that could benefit from simpler solutions like sbondCo/Watcharr or SikandarJODD/svelte-animations.

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 multiple JavaScript frameworks
• Highly customizable and flexible for complex table requirements

Cons

• Steeper learning curve compared to simpler table libraries
• Requires more setup and configuration than some UI-focused alternatives
• May be overkill for basic table needs, adding unnecessary complexity

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 interactions, unlike more general UI libraries like Storybook or Svelte
• 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 AI-specific concepts
• Potentially less customizable in terms of UI components compared to component libraries like shadcn-svelte or melt-ui

huntabyte/shadcn-svelte is a port of the popular shadcn/ui components for Svelte, providing a set of 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 language and theming system, making it easier to create cohesive user interfaces
• Leverages the power of Svelte's reactivity and component model, resulting in efficient and performant UI elements

Cons

• As a port of shadcn/ui, it may lag behind the original React version in terms of new features and updates
• The project is relatively new compared to some other UI libraries, which may result in a smaller community and fewer resources
• While customizable, it may not offer the same level of flexibility as more established UI frameworks like Chakra UI or Material UI
