Changelog

effector 19.1.0

• Add support for event.filter with common predicate functions

import {createEvent} from 'effector'

const event = createEvent()

// that event will be triggered only when fn returns true
const filtered = event.filter({
  fn: x => x > 0,
})

filtered.watch(x => console.log('x =', x))

event(-2) // nothing happens
event(2) // => x = 2
