1. unit (Store/Event/Effect/Domain/Scope): unit to be erased
2. config: ({deep?: boolean}) (optional): config object

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
