Syntax highlighting in neovim HEEX

[wwaldner]

Are there any plugins/configuration settings that provide syntax highlighting/formatting for eex/heex templates in Neovim? I am trying to setup Neovim for Elixir dev and this seems to be the missing part yet.

I am using Treesitter with the elixir and heex plugins installed.

require("nvim-treesitter.configs").setup(
    {
        ensure_installed = {
            "eex",
            "elixir",
            "erlang",
            "heex",
            "html",
            "surface",
            ...
        },
        ...
        highlight = {enable = true},
    }
