Can a data object in Vue be automatically updated when there are changes in the database?

I am developing a web application where users can create an account and join rooms. Once inside a room, they have the ability to click a button that randomly selects another user in the room to give a gift to. My challenge lies in updating a data object in Vue when the database is updated for all users. The issue arises when a new user joins a room - the new user receives the updated data object, but the existing users have outdated information. So my question is, how can Vue update a data object if the database is updated?

When I refer to a data object, it resembles something like this:

data() {
 return {
  room: { name: "room", users: [] }
 }
}

Would the update() lifecycle hook handle this situation, or should I use computed()? And just a reminder, the solution needs to update the data object for ALL users who are part of the room.

I am utilizing Vue2 as well as Vuetify for my development.

Answer №1

In the scenario described by Fatur, where users can freely join and leave a room in an open-game style setting, it is advisable to establish a continuous web connection using a web socket to keep track of who is present in the room.

If you are already utilizing the Vuetify framework, integrating Vue Native Websocket into your project should be relatively straightforward. While I have not personally used it, this tool seems to be a reliable solution that receives regular updates.

An alternative approach could involve querying the database or API for all current users in the room each time a user initiates a gift action. However, this method is not ideal as new users may join while the request is being processed, which could lead to inaccuracies. Furthermore, relying solely on this procedure could strain your database or API resources, especially if multiple rooms are involved, making it a less favorable option.
