Nano Stores

src="https://nanostores.github.io/nanostores/logo.svg">

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 797 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.

``ts
// store/users.ts
import { atom } from 'nanostores'

export const $users = atom([])

export function addUser(user: User) {
$users.set([...$users.get(), user]);
}
`

`ts
// store/admins.ts
import { computed } from 'nanostores'
import { $users } from './users.ts'

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

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

export const Admins = () => {
const admins = useStore($admins)
return (



{admins.map(user => )}



)
}
