with Lua integration, you can create Neovim Lua modules
you can start with lua-intro section from Neovim help system; it gives all of the information on the things you need to get started with configuring Neovim with Lua as well as pointers for more things to do with Lua;
Neovim also extends the Lua standard library found in vim object; see the lua-stdlib in Neovim help system

Setting configuration with Lua

There are some equivalent setting values in Lua versus Vimscript. For more information, see the lua-vimscript help section.

Description	Vimscript statement	Lua equivalent
Setting options	`set number relativenumber`	`vim.opt.number, vim.opt.relativenumber = true, true`
Setting local options	`setlocal spell`	`vim.opt_local.spell = true`
Running Vimscript commands	`colorscheme nord`	`vim.cmd "colorscheme nord"`
Setting buffer-specific options	`b:ale-enabled=1`	`vim.b["ale-enabled"] = 1`

Some more general things you generally want to know:

You can still execute Vimscript with vim.cmd. For more information, see :h lua-vimscript from the help system.
You can access environment variables through vim.env — e.g., vim.env.HOME, vim.env.MYVIMRC.
Highlight options are mostly in vim.highlight — e.g., highlight clear SpellCap versus vim.highlight.
You can manipulate variables of various scopes from vim.{g,b,..,t}. To see more details, see lua-vim-variables help section.
vim.opt will return an Option object, it has a common API. to learn more about it, see vim.opt and its subsections.

This is a list of Neovim Lua modules that can serve as a basis for learning to interact Neovim with Lua.

Several people have already replaced their already existing Vim configurations with Neovim.

TJ DeVries' Neovim config is fully written in Lua complete with his own plugins.
ThePrimeagen's public dotfiles contains Neovim config written in Lua.
