Feature Request: Dynamic Bidder Modules

[ReinoutStevens]

Type of issue

Feature Request

Description

As a publisher, we're adding more and more partners. Many of these partners are country-specific (e.g. they only run in 1 specific country). Having many partners has 2 downsides:

• it increases the bundle size of Prebid
• Some bid adapters fetch and execute external JS, even when that bid adapters is not used in the auction

While we can mitigate this problem by building multiple prebid versions ourselves, it doesn't really scale when adding more country-specific partners.

It would be better if Prebid supported dynamically loading in bid adapters, either through a specific api, or the moment the bidder is used in an auction for the first time.

Which bid adapter runs external js ?

[ReinoutStevens]

Afaik in our case that was Criteo and Adagio. Adagio loads in external stuff, even when they are not used in the auction. Not sure whether that was the case for Criteo, or if that only happens when they were part of the auction.

Those are both no longer in #11720 :)

#6221 is a dupe btw, what do you think of the resolution there, to rely on #5287? There's demand for this with id modules too, no need to call some id modules until you've got an authenticated user

[ReinoutStevens]

The approach of #5287 would work for us, and we could just use dynamic imports in our ads wrapper
