Phlex UI components with Stimulus behaviors — starting with a full charting toolkit.

clowk-phlex is a dual-artifact UI library. The markup is a Ruby gem; the behavior and styles are an npm package. They are two halves of one library, version-locked, and meet only at runtime through data-* attributes:

Charts is the first module (area / line / bars, single & multi-series, radial & linear gauges, number tiles, sparklines) with the full dashboard feature set: range & interval pickers, a visibility / order / columns settings panel, drag-to-resize, interactive legends, hover tooltips, and a maximize hook. UI primitives (Button, Drawer, Sidebar, Dropdown, Table…) migrate in next under the same namespaces.

# Gemfile
gem "clowk-phlex"

pnpm add @clowk/phlex

// your Stimulus entrypoint
import { registerClowkPhlex } from "@clowk/phlex"

registerClowkPhlex(application)

/* your stylesheet — self-contained, preflight-free, all in @layer clowk.
 * If you run Tailwind, declare the layer order so `clowk` sits between `base`
 * and `utilities` (above the preflight resets it must beat, below your own
 * utilities it must not override), then import it. */
@layer theme, base, components, clowk, utilities;

@import "tailwindcss";
@import "@clowk/phlex/core";

class Dashboard < ApplicationView
  include Clowk::Phlex   # → short names: Charts::Card, UI::Dropdown, …

  def view_template
    render Charts::Card.new(label: "HOST · CPU", color: "#5B8DEF", unit: "%",
                            chart_type: "area", points: points, range_ms: range_ms)
  end
end

Components take plain data (hashes / kwargs) — no models, no DB, no app routes. You bring the container (modal, drawer, page); the lib brings the content and its behavior.

The shipped CSS references --color-clowk-* design tokens. Override them to retheme without touching Ruby:

:root {
  --color-clowk-accent: #5b8def;
  --color-clowk-surface: #12151c;
}

Tailwind v4 is optional — needed only to extend components with your own utility classes via the class: passthrough.
