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 340 and 864 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.ts'

export const $admins = computed($users, users => users.filter(i => i.isAdmin))

// components/admins.tsx
import { useStore } from '@nanostores/react'
import { $admins } from '../stores/admins.ts'

export const Admins = () => {
  const admins = useStore($admins)
  return (
    <ul>
      {admins.map(user => (
        <UserItem user={user} />
      ))}
    </ul>
  )
}
