Add auto-import neovim plugin

[florentdestremau]

I have tried for an afternoon working in neovim for and the first thing I'm missing coming from an IDE is the auto import of namespaced vendors (in PHP and in Node JS).
I've tried installing https://github.com/Galooshi/import-js but never managed to make it work. I'm very new to neovim and it's package system, and it's made a bit harder with the Lazyvim overhead where conventions are not the same as documentation suggests.

Does someone have a working setup a bit more in-depth for JS and/or PHP on this matter ?
