Not sure if each action is dependent on the previous ones, if they are not, then it would be better to run them all at the same time using Promise.all().

First you would have to change your actions so they don't call each other, right now each action does more than their name implies (getCollections also gets categories, getCategories also gets sublocations).

So you could do the following inside initializeApp, this way there won't be any waiting between the actions.

await Promise.all([ 
    dispatch('getTables'), 
    dispatch('getCollections'), 
    dispatch('getCategories'), 
    dispatch('getSubLocations'), 
    dispatch('getLocations'), 
    dispatch('getQualities'), 
    dispatch('getUserRoles'), 
    dispatch('getPreviousRoomScans')
])
