  • v0.18.2 Changes

    • 🛠 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),
})
    • ➕ Add umd bundle to npm. Therefore, you can use cdn to include library without bundlers
    <!DOCTYPE html>
<html>
  <head>
    <script src="https://unpkg.com/[email protected]/effector.umd.js"></script>
  </head>
  <body>
    <script>
      const header = document.createElement('h1')
      document.body.appendChild(header)
      const $text = effector.createStore('hello')
      $text.watch(str => (header.innerHTML = str))
    </script>
  </body>
</html>

  • v0.18.1 Changes

    • ➕ Add forward: common function for forwarding updates and events
    import {forward} from 'effector'

const unsubscribe = forward({
  from: Event | Store,
  to: Event | Store | Effect,
})
    • ➕ add support for storages in store.on
    import {createStore} from 'effector'

const $name = createStore('name')
const $counter = createStore(0).on(name, (count, name) => count++)
    • 👍 Allow to pass {handler: Function} as second argument to createEffect
    import {createEffect} from 'effector'

const callApiFx = createEffect('call api', {
  async handler(url) {
    const res = await fetch(url)
    return res
  },
})
    • 👉 Make effect.use return the same effect instead of void (ability to chain method calls)
    import {createEffect} from 'effector'

const callApiFx = createEffect('call api').use(url => fetch(url))

  • v0.18.0 Changes

    • 🐎 Log events into Chrome devtools performance timeline
    • ➕ Add notifications about errors inside computation chain
    • ➕ Add store.defaultState property
    • effector-react: Add createComponent
    • 👉 Make withProps static function
    • 👉 Make effect return plain promise

  • v0.18.0-beta.10 Changes

    • ➕ Add Gate
    import {type Gate, createGate} from 'effector-react'

const AppGate = createGate('app')
const MainPageGate = AppGate.childGate('main page')

export default ({isLoading, meta}) => (
  <div>
    Application
    <AppGate isLoading={isLoading} />
    {!isLoading && (
      <div>
        Main page
        <MainPageGate meta={meta} />
      </div>
    )}
  </div>
)
AppGate.state.watch(({isLoading}) => isLoading)

  • v0.17.7 Changes

    • Keep and replay the whole domain history for every new hook

  • v0.17.6 Changes

    • ➕ Add domain hooks for handle new events, effects or stores in domain.
    import {createDomain} from 'effector'

const mainPage = createDomain('main page')
mainPage.onCreateEvent(event => {
  console.log('new event: ', event.getType())
})
mainPage.onCreateStore(store => {
  console.log('new store: ', store.getState())
})
const mount = mainPage.event('mount')
// => new event: main page/mount

const pageStore = mainPage.store(0)
// => new store: 0
    • 👌 Improve TypeScript typings

  • v0.17.5 Changes

    • ➕ Add ability to use createEvent, createEffect and createDomain without arguments (omit name)

    • ➕ Add createWrappedDomain to watch all nested events and updates
    • ➕ Add extract to watch only part of nested storages
