0.1.0 - 2026-07-04

Added

  • WYSIWYG SVG canvas editor for OpenGraph image templates — text, image, rect, and stamp elements, with {{slot}} (consumer-wired) and [[global]] (site_url, site_host, site_name, page_url, page_locale) variable syntax
  • Hierarchical template assignment system (e.g. post → group → default); admin modal for CRUD plus live preview against a real published resource
  • SVG → PNG rendering pipeline (Render.render_url/2): prefers the :resvg NIF, falls back to the resvg CLI, rsvg-convert, or ImageMagick; disk cache keyed by a SHA-256 of (template, canvas, values, module_key)
  • refine_og/4 integration seam for consumer modules — kill-switch via enabled?/0, pass-through on any resolution error or missing template so a public page render can never crash on OG rendering
  • preview_og_image_url/3 for consumer editors to show "what the plugin will produce" without swapping the live OG image
  • GET /phoenix_kit/og-image/:key image controller — image/png without a charset suffix (Telegram drops previews on binary MIME with a text charset), 30-day immutable cache headers, configurable cache directory
  • Consumer opt-in via two callbacks on the consumer's PhoenixKit.Module implementation: og_variables/0 (declares available variables) and og_resolve/2 (fetches values at render time); first consumer wired up is phoenix_kit_publishing
  • Activity logging for template and assignment CRUD
  • Admin dashboard integration: OpenGraph overview tab plus Templates and Assignments subtabs
  • phoenix_kit_og_templates and phoenix_kit_og_assignments schemas (migration V139), with a partial-unique-index pair so Postgres NULL scope_uuid (module-wide default) and per-scope assignments don't collide

Fixed

  • The template editor's /new route no longer leaks an orphaned template row on every fresh page load — creation is now gated on connected?/1 since LiveView mounts twice (disconnected + connected) for a full page load
  • Render.Svg no longer hardcodes http://localhost:4000 for host-relative image sources (e.g. the signed local-storage fallback URL); it now degrades the same way any other unresolvable image href does
