Confetti doesn't work after obfuscation.

@catdad Could you please help with this?

"javascript-obfuscator": "^2.11.0" used

[catdad]

Hmm... what have you done to investigate so far? I assume you have reason to believe this is an issue with this library and not an issue with the obfuscator?

[romua]

@catdad just high level investigation. Also it is worth mentioned I'm using your wonderful library inside angular-electron app(so all kinds of angular minifications/optimizations are happening). It happens after obfuscation only(so my CI steps: build(works here)> obfuscate(errors here))

I think this may be due to the main function being obfuscated, the code injected may not be able to run in a worker env. Not exactly sure why (like a transpiled function not available?)

same here :(

I've also run across an issue where bundling this library produces an invalid main file, I believe the core issue here is that bundlers don't garantee that all code required for the library will remain inside of the main function, I've set up a minimal example here that shows this using esbuild with keepNames and minifySyntax enabled (this is a config simular to what we use in prod to have a smaller bundler with correct stack names).

in the output shown you can see that esbuild has injected a helper function for defining function names at the top of the file outside of the main function we provided it. the only clear solution I can see to this is to provide a pre stringified version of the library or perhaps have a bundler friendly export that re-imports a copy as a worker (though this may not be safe across all bundlers)
