Overview

Alveron is an Elm-inspired state management library for React that supports asynchronous side effects as a first class citizen.

It's super lightweight at only 1.2kb and uses React's useState under the hood.

Installation

The Gist

import * as React from 'react'
import { useStore } from 'alveron'

const model = 0
const actions = {
  increment: (prevState) => [prevState + 1],
  decrement: (prevState) => [prevState - 1],
}

function Counter() {
  const [state, { increment, decrement }] = useStore(actions, model)

  return (
    <div>
      Count: {state}
      <button onClick={() => increment()}>+</button>
      <button onClick={() => decrement()}>-</button>
    </div>
  )
}
