  messages,
});

{
  messages: {
    errors: [],
    toasts: {},
  }
}

Errors

The errors state only exposes basic actions and selectors

addErrors(errors)

addErrors expects an array of errors that will be set.

clearErrors()

clearErrors removes all the errors currently stored in the state.

getErrors(state)

The getErrors selector returns the full array of currently stored errors.

---

Toasts

The toasts state exports actions, selectors and a list of constants representing the toast types.

addToast(message, type)

addToast needs a message string and a type. It is highly recommend to use the types exported by the package, although it is possible to use custom ones.

removeToast(id)

removeToast removes from the state any toast with the matching ID. whenever a toast is added to the state a unique ID is assigned to it.

getToasts(state)

The getToasts selector returns the object containing all the existing toasts, with each message assigned to a unique ID.

{
  'f64f2940-fae4-11e7-8c5f-ef356f279131': {
    message: 'toast message',
    type: TOAST_ERROR,
  },
}
