That’s not great. I bet the project I was using it on is quite old. In the meantime, as stated https://www.reddit.com/r/emacs/comments/1865s7b/recommended_setup_for_react_development/kb7kej1/ envrc and layout node seems to work for me!

Looks like adding layout node to .envrc (direnv) would remove the need for add-node-modules-to-path for me

I use:

• apheleia for code formatting via prettier
• envrc for managing node versions
• add-node-modules-to-path
• js-ts-mode, typescript-ts-mode, tsx-ts-mode via treesit-auto
• eglot with tsserver

Along with something for eslint in flymake
