Top Svelte State Management Libraries
Top 5 Projects Compared
TanStack Query (formerly React Query) is a powerful data fetching and state management library for React applications.
Code Example
const { data, isLoading, error } = useQuery('todos', fetchTodos);
if (isLoading) return 'Loading...';
if (error) return 'An error occurred: ' + error.message;
Pros
- Provides robust caching and automatic background refetching, reducing network requests and improving performance.
- Offers a simple and intuitive API for managing server state, making it easier to handle complex data fetching scenarios.
- Supports various frameworks beyond React, including Vue and Svelte, making it versatile for different project needs.
Cons
- Has a steeper learning curve compared to simpler state management solutions like nanostores or storeon.
- May be overkill for small projects or applications with simple data fetching requirements.
- Requires more setup and configuration compared to lightweight alternatives like redux-zero.
Nanostores is a tiny state management library for React, Preact, Vue, Svelte, and vanilla JS applications.
Code Example
import { atom } from 'nanostores'
const count = atom(0)
count.subscribe(value => console.log('Count:', value))
count.set(count.get() + 1)
Pros
- Extremely lightweight (less than 1KB) compared to larger state management solutions like Redux or TanStack Query
- Framework-agnostic, supporting multiple popular frontend libraries and vanilla JS
- Simple API with minimal boilerplate, making it easy to learn and use
Cons
- Lacks advanced features like automatic caching and request deduplication found in TanStack Query
- Doesn't provide built-in UI components or styling solutions like Chakra UI's Zag or Ark
- May not be suitable for very large applications with complex state management needs, where Redux or Storeon might be more appropriate
Chakra UI Zag is a collection of framework-agnostic UI component primitives for building accessible and customizable user interfaces.
Code Example
import * as accordion from "@zag-js/accordion"
import { useMachine, normalizeProps } from "@zag-js/react"
const [state, send] = useMachine(accordion.machine({ id: "1" }))
const api = accordion.connect(state, send, normalizeProps)
Pros
- Framework-agnostic, allowing for use across different UI libraries and frameworks
- Highly accessible and customizable components out of the box
- Focuses on low-level primitives, providing more flexibility in implementation
Cons
- Requires more setup and configuration compared to full-fledged UI libraries
- Smaller ecosystem and community compared to more established projects like TanStack Query
- Less opinionated, which may lead to more decision-making and potential inconsistencies in large projects
Chakra UI Ark is a headless UI component library for building accessible and customizable React applications.
Code Example
import { useButton } from '@chakra-ui/ark'
function Button(props) {
const buttonProps = useButton(props)
return <button {...buttonProps} />
}
Pros
- Provides a more flexible and customizable approach compared to TanStack Query and Redux Zero, focusing on UI components rather than state management.
- Offers better accessibility features out-of-the-box compared to nanostores and storeon.
- Provides a more comprehensive set of UI components compared to Chakra UI Zag, which focuses on specific interactions.
Cons
- Less suitable for complex state management compared to TanStack Query, nanostores, storeon, and Redux Zero.
- May have a steeper learning curve for developers familiar with traditional UI libraries, as it requires more custom styling and implementation.
- Lacks the specific optimizations for micro-frontends that nanostores provides.
Storeon is a tiny (173 bytes) state manager for JavaScript applications with a minimalistic API.
Code Example
import { createStore } from 'storeon'
const counter = store => {
store.on('@init', () => ({ count: 0 }))
store.on('inc', ({ count }) => ({ count: count + 1 }))
}
const store = createStore([counter])
Pros
- Extremely lightweight compared to other state management solutions like Redux or MobX
- Simple API with a small learning curve, making it easy to adopt and use
- Framework-agnostic, can be used with React, Vue, or vanilla JavaScript
Cons
- Limited ecosystem and community support compared to more established libraries like Redux or TanStack Query
- Lacks built-in advanced features like middleware or time-travel debugging found in larger state management solutions
- May not be suitable for complex applications with intricate state management requirements
