neovim/nvim-lspconfig Configuration

Content attributed to @slavamak

Set up shopify_theme_ls with Neovim's built-in LSP using the following configuration:

require("lspconfig").shopify_theme_ls.setup {}

This setup requires the Shopify CLI, which can be installed via npm:

npm install -g @shopify/cli

Alternatively, to manage the installation of the Shopify CLI using Mason:

require("mason").setup {}
require("mason-lspconfig").setup {
    automatic_installation = true
}

require("lspconfig").shopify_theme_ls.setup {}
