[Feature Request] Filter wishlist to games containing a demo

User request from ITAD Steam group

Hmm, I'm curious for the use case. Why does it matter if a game has a demo or not?

[MxtOUT]

I find this very useful indeed.
If you're planning to buy a game (because it's on your wishlist), but do not know which, you can apply this filter and go through some demos to try them out

Thanks for the consideration. If this feature gets implemented, that'd be fantastic.

Any chance we get to see this feature in the near future? Any news?

[Revadike]

To implement this, we either have to scrape each wishlist game's store page, or use some sort of database. From experience I can tell backend stuff takes ages to get implemented here for Augmented Steam.
I think you'll have better luck requesting this feature for the SteamDB extension. They already have a great database that is perfect for this.

This endpoint can be used to get the demo appid for a given app: https://store.steampowered.com/saleaction/ajaxgetdemoevents?appids[]=

So we can run something like this on wishlists to get a list of apps with demos:

const params = g_rgWishlistData.map(({appid}) => `appids[]=${appid}`).join("&");
await fetch(`https://store.steampowered.com/saleaction/ajaxgetdemoevents?${params}`)
    .then(data => data.json())
    .then(({info}) => info.filter(val => !!val.demo_appid).map(({appid}) => appid));

The only problem I can think of is the query parameter length, which gets longer the more items on the wishlist. I tried with close to 400 items without problems, but what about people with thousands of items? I assume browsers have a limit on the length of query parameters.

Hi, I don't know if is cool to drop links to other repositories but there is an extension, that kinda works and shows demos https://github.com/bar-bar-bar-bar-bar/demos-in-my-steam-wishlist but its only for chrome. Maybe it will guide someone smart on how to add this. Cheers!

Interesting project! Seems like they did it similar to what I brought up here #1614 (comment), problem is the list needs to be frequently updated since demos come and go pretty fast. My solution linked above gets the data directly from Steam, which is much more reliable but unfortunately might not be suitable for large-scale depolyment...
