Installation

npm install react-state-fire

Usage

There is no need to pass an inital store to the Provider just add whatever you want with fire - it let's you add a new state instance whenver/wherever you want. It works a little bit like Recoil but its not as fancy

import { fire, useFire, Provider } from 'react-state-fire'

const store = fire(0)
function FirstCounter() {
  const [count, setCount] = useFire(store)

  return (
    <div>
      <h1>First counter</h1>
      {count}
      <button onClick={() => setCount((prev) => prev + 1)}>increment</button>
    </div>
  )
}

const store2 = fire(1337)
function SecondCounter() {
  const [count, setCount] = useFire(store2)

  return (
    <div>
      <h1>Second counter</h1>
      {count}
      <button onClick={() => setCount((prev) => prev + 1)}>increment</button>
    </div>
  )
}

function Reader() {
  const [firstCount] = useFire(store)
  const [secondCount] = useFire(store2)

  return (
    <div>
      <p>{firstCount}</p>
      <p>{secondCount}</p>
    </div>
  )
}

function App() {
  return (
    <Provider>
      <FirstCounter />
      <SecondCounter />
      <Reader />
    </Provider>
  )
}

Pass a name to your fire to keep track of them.

const store = fire('some-value', 'some-name')

If you don't pass in a name you still get a default name in a lowercase letter. The first fire you initialize will have the name "a" and the second will be "b" and so on…

Here is a full example with the hook useAllFires to retrieve all fire's that are stored

import { fire, useFire, useAllFires, Provider } from 'react-state-fire'

// first argument is init value and second argument is the name of the fire
const namedFireOne = fire('hello', 'helloName')
function NamedFireComponentOne() {
  const [count, setCount] = useFire(namedFireOne)

  return (
    <div>
      <h1>NamedFireComponentOne</h1>
      {count.value}
      <button onClick={() => setCount('something else')}>click me!</button>
    </div>
  )
}

// first argument is init value and second argument is the name of the fire
const namedFireTwo = fire('goodbye', 'goodbyeName')
function NamedFireComponentTwo() {
  const [count, setCount] = useFire(namedFireTwo)
  return (
    <div>
      <h1>NamedFireComponentTwo</h1>
      {count.value}
      <button
        onClick={() =>
          setCount((prev) => prev.value + ' something with previous value')
        }
      >
        click me!
      </button>
    </div>
  )
}

function ReadAllStores() {
  const allFires = useAllFires()
  // below you can retrieve all fires by name
  return (
    <div>
      <p>{allFires.helloName}</p>
      <p>{allFires.goodbyeName}</p>
    </div>
  )
}
function App() {
  return (
    <Provider>
      <NamedFireComponentOne />
      <NamedFireComponentTwo />
      <ReadAllStores />
    </Provider>
  )
}
