I’m making a React component library to abstract out some components I use in multiple projects. Some projects are made with CRA, some with Gatsby, some might be something else, etc. I used the Neutrino.js framework/toolchain as it was linked on the React docs site, but the issue I ran into is that by default the output files of the build all use the window object, which causes gatsby build to break as window doesn’t exist in Node/SSR.

I understand something like the following won’t be legal: (function(){ import thing from ‘./thing.js’; })(); but does this mean import is only legal at the top of the module script?
