How to set a custom grep (rg) command?

[tonebender]

Sorry for the basic question, but I'm coming from fzf.vim, and in there I have custom def of the Rg vim command, in order to be able to give arguments to Rg, like ":Rg -t js searchterm" to search only in .js files. It looks like this in .vimrc:
command! -bang -nargs=* Rg call fzf#vim#grep("rg --column --line-number --no-heading --color=always --smart-case --with-filename ".<q-args>, 1, fzf#vim#with_preview(), <bang>0)

How would I set this in fzf.lua in the cleanest possible way?

Thanks!

Many different ways:

• to send a static command use live_ grep({ cmd = "rg …" }) (or use rg_opts)
• By default you can limit globs, search for regex -- *.ts
• For more control: https://github.com/ibhagwan/fzf-lua/wiki#how-can-i-send-custom-flags-to-ripgrep-with-live_grep

Thanks so much for the quick reply!
I think I'll have to try this from the ground up...
