Description of change

Possibility to overwrite default fun-hooks module configuration used by Prebid.js while importing them.

Need to change default useProxy value of fun-hooks configuration https://www.npmjs.com/package/fun-hooks#configuration in some cases.

Example:

$$PREBID_GLOBAL$$.hookSettings = {
  useProxy: false
}

Can I ask why you'd want to disable the use of Proxy?

Hi,
some of the pages where I use Prebid.js to display video overrides global Proxy class. This is caused by PureMvc framework, embedded in video player iframe which I use, for example: https://tinyurl.com/y2ga4e56
I have this problem with a lot of services and this small change is the best option for me to handle this issue.

I'd rather not have fun-hooks be configurable through Prebid.js mainly because it has to be configured before loading (as you noticed) which is user-unfriendly and requires hacky solutions outside of the standard pbjs.setConfig().

However, this really is a problem in determining whether or not Proxy is actually the native Proxy. I updated the fun-hooks library to do a check for Proxy.revocable which is part of the Proxy API (which the Proxy global made by PureMVC is not), so this new check should fail on your page and it should fall-back gracefully to the non-Proxy hooks.

Thanks for your help, now everything works fine.
