Yarn 3 documentation doesn't offer any good alternative to postinstall?

[laurent22]

Yarn's documentation recommends not to use postinstall scripts. In theory this is probably a good idea but in practice it's not clear how to avoid it.

In our case, the postinstall script is going to build some assets such as script files and JSON indexes, compile JSX scripts, run electron-rebuild and more. Yarn documentation covers only very easy cases like the Open Collective postinstall scripts (that could be removed from the doc actually since they don't recommend this anymore), or converting binary files to WebAssembly.

So the only advice that Yarn has to offer is to build native packages using WebAssembly, but that ignores the vast majority of postinstall scripts which often do a lot more. Is there any official advise about this?
