global function defined in one partytown script is not accessible to other partytown scripts

Please check this sandbox : https://vpxcwd.csb.app/ ( https://codesandbox.io/s/partytown-global-functions-vpxcwd )

sandbox uses latest Partytown version 0.5.0

In this sandbox, there are two scripts foo.js and bar.js both are partytown scripts and so both runs in same worker thread.

foo.js defines a function foo.
bar.js tries to use function foo

Expectation: bar.js should be able to use function foo

Problem: bar.js is not able to use function foo and throws error

There currently is a config called globalFn and it’s documented only in the types for now: https://github.com/BuilderIO/partytown/blob/072ac28bc17aedb6b97d01ee2c99013daa1064e7/src/lib/types.ts#L390-L398

Still trying to think of the best way to tackle this problem without having to add another config, which would rarely be obvious.

@garethweaver Thanks for the update!

Just to let you know that the original issue I mentioned in this issue is fixable, I actually created my own library (Proxytown) that works similar to Partytown where I fixed this issue.

In that library one script running in worker can access other script’s globally defined variables or even main thread’s global variables without having any kind of configuration.

Here it is : https://github.com/MananTank/proxytown

I created this library 3 months ago and completely forgot to post it here 😅, I thought I would post it here once it’s fully tested - But I never got the time to do that.

Anyway,

Here is an example sandbox using this library: https://7ebxo6.csb.app/ ( https://codesandbox.io/s/7ebxo6?file=/index.html )

@adamdbradley May be you can check out this library (proxytown) and see if this is something you guys can implement in partytown

There are some bugs when Symbols are used as keys. But for the most part, Everything seems to work with that architecture. Library is also pretty lean and I did not have to mock any WEB/DOM APIs.

Hopefully, I will get some free time in future to properly test this library and release beta version.
