Fix promise warning for effects

re-exportsChangelog
effector, effector-react, effector-vue 19.0.0
To indicate the stability of the project, we adopting semantic versioning and happy to announce version 19.0.0 for all packages. And to make the transition easier, that release contains no breaking changes; simple replacement of "^0.18.*" to "^19.0.0" is safe for sure ☄️

import {createStore, createEvent, createStoreObject, combine} from 'effector'
const updateField = createEvent('update $field value')
const $field = createStore('').on(updateField, (state, upd) => upd.trim())

Use the new kernel. Provide improved eventual consistency: any side effects will be triggered only after performing all pure computations
Add is
namespace for all type validators
import {createStore, createEvent, is} from 'effector'
const $store = createStore('value')
const event = createEvent('some event')
is.store($store) // => true
is.event($store) // => false
is.unit($store) // => true
is.store(event) // => false
is.event(event) // => true
is.unit(event) // => true
is.store(null) // => false
is.event(null) // => false
is.unit(null) // => false
Add clearNode
to break references and subscriptions between events, stores, etc
Add support for custom datatypes by making step
constructors, createNode
and launch
functions public
import {createNode, launch, step, createStore} from 'effector'
const $target = createStore(0)
$target.watch(n => console.log('current n = ', n))
// => current n = 0
const customNode = createNode({
scope: {max: 100, lastValue: -1, add: 10},
child: [$target], // you can forward later as well
node: [
step.compute({
fn: (arg, {add}) => arg + add,
}),
step.filter({
fn: (arg, {max, lastValue}) => arg < max && arg !== lastValue,
}),
step.compute({
fn(arg, scope) {
scope.lastValue = arg
return arg
},
}),
],
})
launch(customNode, 3)
// => current n = 13
launch(customNode, 95)
// no reaction, as 95 + 10 > 100
launch(customNode, 5)
// => current n = 15
launch(customNode, 5)
// no reaction, as we filtered it out with step.filter
fromObservable
, ensure it works with redux
as a typical library with Symbol.observable
supportimport {fromObservable} from 'effector'
import * as redux from 'redux'
const INCREMENT_STATE = 'INCREMENT_STATE'
const reduxStore = redux.createStore((state = 1, action) => {
switch (action.type) {
case INCREMENT_STATE:
return state + 1
default:
return state
}
})
const updateEvent = fromObservable(reduxStore)
updateEvent.watch(state => {
console.log('redux state = ', state)
})
reduxStore.dispatch({type: INCREMENT_STATE})
// => redux state = 1
version

console.log(version)
// => 0.18.6
import {createEffect, createEvent, forward} from 'effector'
const trigger = createEvent()

Fix webpack usage issue. To prevent this in a future, webpack integration test was added.
Improve typescript typings for createApi
. This code example became type checked
import {createStore, createApi} from 'effector'
const $text = createStore('')
const {addMessage, cut} = createApi($text, {
addMessage: (text, message) => text + `\n` + message
cut: (text, {fromIndex, size}) => text.slice(fromIndex, fromIndex + size),
})
