PhoenixKitDashboards

Customizable dashboards for PhoenixKit.

Compose dashboard pages from widgets contributed by any PhoenixKit module. A widget is a self-contained Phoenix.LiveComponent; a dashboard is a responsive grid of widget instances — each anchored at an explicit cell (gaps allowed, no overlap) and spanning w columns × h rows per breakpoint tier (TV 16 / Desktop 12 / iPad 8 / Phone 4 columns), with undesigned tiers auto-derived by reflow + compact. A second dashboard type is a pixel canvas (exact-px placement, deliberate overlap via z-order). The grid is server-rendered (Phoenix-first — it renders and is operable without JavaScript via the settings modal); drag/resize/catalog-drag are progressive enhancement via the module's own hooks (js_sources/0). Layouts persist per user (personal dashboards) and per system/role (shared dashboards).

Instant tier detection (recommended)

The grid builder picks the responsive tier (TV/Desktop/iPad/Phone) that best fits the viewer's screen. By default that needs a client hook round-trip after connect, so the dashboard briefly shows a loading state. Pass the viewport in your LiveSocket connect params and the tier is resolved server-side at mount — the dashboard loads straight into the right layout:

// assets/js/app.js — a closure so reconnects re-read the width
const liveSocket = new LiveSocket("/live", Socket, {
  params: () => ({_csrf_token: csrfToken, viewport_width: window.innerWidth}),
  hooks: {...window.PhoenixKitHooks},
})

Hosts that don't pass viewport_width keep working — detection falls back to the hook round-trip.

Installation

Add to your PhoenixKit host app's mix.exs:

{:phoenix_kit_dashboards, "~> 0.1"}

Run mix deps.get, then apply core's migrations with mix phoenix_kit.update. The phoenix_kit_dashboards table ships as core PhoenixKit migration V133 — modules do no DDL of their own, so there is no migration to run from this package.

The module auto-discovers — a Dashboards tab appears in the admin sidebar.

Routes

Path	LiveView	Purpose
/admin/dashboards	DashboardsLive	Manage page — list / create / delete dashboards
/admin/dashboards/:uuid	BuilderLive	The 2D grid builder for one dashboard

Paths honor the host's PhoenixKit URL prefix + locale via PhoenixKitDashboards.Paths — never hardcode them.

Settings keys

Key	Default	Meaning
dashboards_enabled	false	Master enable/disable toggle (set via the admin Modules page or enable_system/0 / disable_system/0)

Exposing widgets from your module

Any module contributes widgets by defining phoenix_kit_widgets/0 returning plain maps. No dependency on phoenix_kit_dashboards is required — the dependency arrow stays one-way (data modules know nothing about dashboards):

def phoenix_kit_widgets do
  [
    %{
      key: "emails.deliverability",        # globally unique, namespaced
      name: "Deliverability",
      description: "Bounce / complaint rates over time",
      icon: "hero-envelope",
      module_key: "emails",                # gates visibility by enablement + permission
      component: PhoenixKitEmails.Widgets.DeliverabilityLive,  # a Phoenix.LiveComponent
      default_size: %{w: 6, h: 2},
      min_size: %{w: 3, h: 1},
      settings_schema: [
        %{key: "window", type: :select, label: "Window",
          options: ["7d", "30d", "90d"], default: "30d"}
      ]
    }
  ]
end

The widget's :component LiveComponent receives :settings (its per-instance customizations), :view (the selected render variant, or nil), :size (%{w:, h:} — the instance's current span, for density-aware rendering) and :scope (the current user's scope) as assigns. Widgets with live data declare refresh_interval (ms, floored to 1s) and are re-send_update/2d by the host. See PhoenixKitDashboards.Widgets.NoteWidget for the smallest reference component, Widgets.ClockWidget for the full view/size/settings shape, and PhoenixKitDashboards.Widget for the whole contract.

Architecture

Module	Responsibility
PhoenixKitDashboards.Widget	Widget type struct + the plain-map provider contract
PhoenixKitDashboards.Registry	Runtime discovery + cached catalog (built-ins ∪ providers), filtered by enablement & permissions
PhoenixKitDashboards.Widgets.*	Built-in widgets (Note, Clock, Module stats)
PhoenixKitDashboards.Schemas.Dashboard	Dashboard schema — JSONB layout of widget instances (table created by core migration V133)
PhoenixKitDashboards.Dashboards	Context: CRUD + clone, layout persistence, add/remove/reorder/resize/move widget, configure (settings+view), layout mode + zoom
PhoenixKitDashboards.Web.DashboardsLive	Manage page (list / create personal·shared·role / clone / delete)
PhoenixKitDashboards.Web.BuilderLive	The server-rendered grid builder — grid + free/pixel modes, resize, live-refresh loop

Status

In place: the provider contract (view variants + size-awareness + live refresh_interval), discovery, persistence, the Phoenix-first server-rendered grid with two layout modes — responsive grid/flow (drag-reorder via core SortableGrid, resize snaps to cells) and a free pixel canvas (drag + resize anywhere, exact px, no snapping, zoom to fit) — corner-drag resize (pixel-smooth; size inputs in the Settings modal as the no-hook fallback), personal / shared / by-role authoring + per-user cloning, live refresh (host send_update loop; the Clock ticks and the projects widgets poll), activity logging, and the full DB/LiveView test harness. phoenix_kit_projects ships five real widgets (projects board, workload, single-project status, ongoing tasks, schedule) — the first provider.

Remaining:

• More widget providers: beyond the built-ins + projects, other modules can emit widgets via phoenix_kit_widgets/0.
• PubSub push refresh: refresh is interval-based today; per-topic PubSub push (vs polling) is an optimization.
• Dynamic settings selects: single-project widgets pick a project via a free-text setting (the settings schema is static); a dynamic picker is a follow-up.

Core dependency: the layout-mode / zoom feature uses a per-dashboard config column shipped as core migration V139 (unreleased). Until it's released, run against local core (PHOENIX_KIT_PATH=../phoenix_kit).
