scopeBind

scopeBind<T>(event: Event<T>): (payload: T) => void

A method to bind event or effect to a scope to be called later. effector supports imperative event calling inside watchers, but sometimes you should bind events to the scope explicitly, e.g. when calling events within a setTimeout/setInterval callbacks.

Arguments

event Event to be bound to the scope

Example

We are going to call changeLocation inside history.listen callback so there is no way for effector to associate event with corresponding scope, and we should explicitly bind event to scope using scopeBind

const installHistory = app.createEvent<any>()
const changeLocation = app.createEvent<string>()

installHistory.watch(history => {

  const locationUpdate = scopeBind(changeLocation)
  history.listen(location => {
    locationUpdate(location.pathname)
  })
})
