I don't care to hear arguments about how npm was _configured wrong_.
A tool with insecure defaults, with a long and storied history of being the vector by which data has been exfiltrated and companies hacked, needs to do an awful lot to justify still being used for any infrastructure our team is responsible for.
My big contention with this project is that if I wanted to use node (or npm; or vite) in any capacity, I would have chosen node for that. I don’t want to use those tools in this context because it serves me worse than a well thought out solution.
The thought out solution is to isolate your frontend into its own directory. You can embed and serve that as part of your Go server. That frontend could have been done with react, vite, jsx, whatever typescript nonsense you want; without the Go parts necessarily needing npm or node in the build process.
I literally have toy projects illustrating the idea (this one is a toy I had AI make with some of my own patterns months ago): https://github.com/SamInTheShell/social/tree/main/frontend
Projects like grafana do stuff like this already. It’s a known good pattern.
