There are many ways to tackle this. You can create a Vuex getter which supplies you a null value or default value to start with. This will at least ensure no errors and it will update whenever your store kicks into gear.

You could create a local computed property and fetch your store value with a mapGetter this way you can also supply a default.

You could have totalPages be set to 0 and use a watcher to update the value whenever your store value changes.

It really depends on context. For example a Vuex getter will be helpful if you need the same default fallback for other components who retrieve the value.
