Changelog

effector-react 21.1.0

• Add support for object and array of events to useEvent. It's a shorthand for calling several useEvent at once (PR #425 by @sergeysova)

export function ExampleComponent() {
  const handlers = useEvent({emailChanged, passwordChanged})

  return (
    <div>
      <input onChange={handlers.emailChanged} />
      <input onChange={handlers.passwordChanged} />
    </div>
  )
}

export function ExampleComponent() {
  const [changeEmail, changePassword] = useEvent([
    emailChanged,
    passwordChanged,
  ])

  return (
    <div>
      <input onChange={changeEmail} />
      <input onChange={changePassword} />
    </div>
  )
}
