useUnit

Bind effector stores to solid reactivity system or, in the case of events/effects - bind to current scope to use in dom event handlers. Only effector-solid/scope version works this way, useUnit of effector-solid is no-op for events and does not require Provider with scope.

useUnit(unit)

Arguments

1. unit (Event or Effect): Event or effect which will be bound to current scope

Returns

(Function): Function to pass to event handlers. Will trigger given unit in current scope

Example

import {render} from 'solid-js/web'
import {createEvent, createStore, fork} from 'effector'
import {useUnit, Provider} from 'effector-solid/scope'

const inc = createEvent()
const $count = createStore(0)
  .on(inc, x => x + 1)

const App = () => {
  const [count, incFn] = useUnit([$count, inc])

  return (
    <>
      <p>Count: {count}</p>
      <button onClick={() => incFn()}>increment</button>
    </>
  )
}

const scope = fork()

render(() =>
  <Provider value={scope}>
    <App />
  </Provider>,
  document.getElementById('root'),
)

useUnit(store)

Arguments

1. store Effector (Store)

Returns

Accessor which will subscribe to store state

Example

import {createStore, createApi} from 'effector'
import {useUnit} from 'effector-solid'

const $counter = createStore(0)

const {increment, decrement} = createApi($counter, {
  increment: state => state + 1,
  decrement: state => state - 1,
})

const App = () => {
  const counter = useUnit($counter)
  
  return (
    <div>
      {counter}
      <button onClick={increment}>Increment</button>
      <button onClick={decrement}>Decrement</button>
    </div>
  )
}

useUnit(shape)

Arguments

1. shape Object or array of (Event or Effect or Store): Events or effects or stores as accessors which will be bound to the current scope

Returns

(Object or Array):

• if event or effect: functions with the same names or keys as argument to pass to event handlers. Will trigger given unit in current scope Note: events or effects will be bound only if useUnit is imported from effector-solid/scope
• if store: accessor signals which will subscribe to the store state

Example

import {render} from 'solid-js/web'
import {createStore, createEvent, fork} from 'effector'
import {useUnit, Provider} from 'effector-solid/scope'

const inc = createEvent()
const dec = createEvent()

const $count = createStore(0)
  .on(inc, x => x + 1)
  .on(dec, x => x - 1)

const App = () => {
  const count = useUnit($count)
  const handler = useUnit({inc, dec})
  // or
  const [a, b] = useUnit([inc, dec])
  
  return (
    <>
      <p>Count: {count}</p>
      <button onClick={() => handler.inc()}>increment</button>
      <button onClick={() => handler.dec()}>decrement</button>
    </>
  )
}

const scope = fork()


render(() =>
  <Provider value={scope}>
    <App />
  </Provider>,
  document.getElementById('root'),
)
