Phoenix Duskmoon UI

Elixir component library providing 80+ LiveView HEEX components that render as HTML Custom Elements (<el-dm-*>) styled by @duskmoon-dev/core.

Version: 9.4.0

Installation

# mix.exs
{:phoenix_duskmoon, "~> 9.4"}

bun add @duskmoon-dev/core @duskmoon-dev/elements @duskmoon-dev/css-art @duskmoon-dev/art-elements

Setup

1. Import components in app_web.ex

defp html_helpers do
  quote do
    use PhoenixDuskmoon.Component    # all dm_* UI components
    use PhoenixDuskmoon.ArtComponent # all dm_art_* decorative components
  end
end

2. CSS (assets/css/app.css)

@import "tailwindcss";
@plugin "@duskmoon-dev/core/plugin";
@import "@duskmoon-dev/core/themes/sunshine";
@import "@duskmoon-dev/core/themes/moonlight";
@import "@duskmoon-dev/core/components";

For custom elements to inherit theme colors, include the element-theme-bridge (ships with the package or copy from the repo's assets/css/element-theme-bridge.css).

For CSS art effects, import each CSS art stylesheet you need:

@import "@duskmoon-dev/css-art/dist/art/eclipse.css";
@import "@duskmoon-dev/css-art/dist/art/snow.css";
/* ... etc */

3. JavaScript hooks (assets/js/app.js)

import { LiveSocket } from "phoenix_live_view";
import * as DuskmoonHooks from "phoenix_duskmoon/hooks";

let liveSocket = new LiveSocket("/live", Socket, {
  params: { _csrf_token: csrfToken },
  hooks: DuskmoonHooks
});

Merge with your own hooks: hooks: { ...DuskmoonHooks, ...MyHooks }.

4. Register custom elements

import "@duskmoon-dev/el-button/register";
import "@duskmoon-dev/el-card/register";
// ... register each el-* package you use

Without registration, <el-dm-*> content is invisible.

5. Register chat elements (if using chat components)

import "@duskmoon-dev/el-chat/register";
