Nano Stores
A tiny state manager for React, React Native, Preact, Vue, Svelte, Solid, Lit, Angular, and vanilla JS. It uses many atomic stores and direct manipulation.
- Small. Between 265 and 814 bytes (minified and brotlied). Zero dependencies. It uses Size Limit to control size.
- Fast. With small atomic and derived stores, you do not need to call the selector function for all components on every store change.
- Tree Shakable. A chunk contains only stores used by components in the chunk.
- Designed to move logic from components to stores.
- Good TypeScript support.
// store/users.ts
import { atom } from 'nanostores'
export const $users = atom<User[]>([])
export function addUser(user: User) {
$users.set([...$users.get(), user]);
}// store/admins.ts
import { computed } from 'nanostores'
import { $users } from './users.js'
export const $admins = computed($users, users => users.filter(i => i.isAdmin))// components/admins.tsx
import { useStore } from '@nanostores/react'
import { $admins } from '../stores/admins.js'
export const Admins = () => {
const admins = useStore($admins)
return (
<ul>
{admins.map(user => <UserItem user={user} />)}
</ul>
)
}
