clearNode(unit, config?: {deep?: boolean}): void

Method for destroying stores, events, effects, subscriptions and domains

Arguments

1. unit (Store/Event/Effect/Domain/Scope): unit to be erased
2. config: ({deep?: boolean}) (optional): config object
   • deep: boolean (optional): erase node and all of its' computed values

Returns

void

Example 1

import {createStore, createEvent, clearNode} from 'effector'

const inc = createEvent()

const store = createStore(0).on(inc, x => x + 1)

inc.watch(() => console.log('inc called'))

store.watch(x => console.log('store state: ', x))

// => store state: 0

inc()

// => inc called

// => store state: 1

clearNode(store)

inc()

// => inc called

Try it

Example 2 (with deep)

import {createStore, createEvent, clearNode} from 'effector'

const inc = createEvent()

const trigger = inc.prepend(() => {})

const store = createStore(0).on(inc, x => x + 1)

trigger.watch(() => console.log('trigger called'))

inc.watch(() => console.log('inc called'))

store.watch(x => console.log('store state: ', x))

// => store state: 0

trigger()

// => trigger called

// => inc called

// => store state: 1

clearNode(trigger, {deep: true})

trigger()

// no reaction

inc()

// no reaction!

// all units, which depend on trigger, are erased

// including inc and store, because it depends on inc

Try it
