VSCode + ElixirLS is usually enough for everything. ASDF is a useful tool to install desired Erlang/Elixir version. Don't think you need anything else

I actually use RTX instead of ASDF as it's significantly faster and doesn't rely on shims. But you should definitely use one of them.

I have also switched to rtx, and even use it in the Next LS build pipeline as an easy way to install Elixir & OTP.

Definitely use ASDF for managing it. I’ve started using it for Node too and I quite like it, even though I was pretty hesitant to start using yet another package manager.

Direnv is generally a good idea once your project reaches a certain level of complexity
