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 binded 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'),

)
