Question about appstore API? about decky-storage-cleaner

[mcarlucci]

Check out line 85: https://github.com/mcarlucci/decky-storage-cleaner/blob/3515a3a13afd17f6f3bc3213f244cfb963c49b45/src/index.tsx#L85C1-L85C1

There, I am checking if the app_type property is equal to 1, which is how Steam identifies games under their digital rights management.

For non-steam games, Steam assigns the game a random id and the app_type is not equal to 1

I get a list of all the games on a users Steam Deck with the following python method:

decky-storage-cleaner/main.py

Line 46 in 3515a3a

async def list_games_with_temp_data(self, dirName, sortBy = 'size'):

For example, here is the entire object returned for The Shadow of the Tomb Raider:
appStore.GetAppOverviewByAppID(750920)

Returns:

Ah yes I understand that part.
What I'm wondering is how does the appStore.GetAppOverviewByAppID retrieve the game name for non-steam games because the ID is just a randomly assigned number, isn't it?

[mcarlucci]

You are correct, Steam does randomly assign an id to non-steam games. They also create a game directory named after the id located in /.steam/steam/steamapps/. If not under the directory, I am not exactly sure how they are storing/retrieving the app metedata returned from appStore.GetAppOverviewByAppID()
