Summary of Changes

  • Live Preview Architecture: Replaced the static footer PreviewWidget with an embedded split-view layout featuring a responsive iframe live preview, device switcher (desktop/tablet/mobile), error page preview routes (403, 404, 500), and real-time state synchronization via secure postMessage messaging.
  • Frontend Bridge (DesignifyPreviewBridge): Implemented a React component in App.tsx that listens for parent iframe preview events (restricted to same-origin and parent window), dynamically updates Easy Peasy state, and updates CSS custom properties for palette colors, background, radius, and font family without full page reloads.
  • Form Schema & Layout Enhancements: Modernized form components using Filament Section schemas with custom icons, updated column layouts, added missing error page image/color inputs (ImageInput and ColorPicker), and enabled live form state updates with debouncing.
  • Localization: Added fallback strings for all newly introduced section headers and editor control actions across all supported language files.

LGTM! The changes are cleanly implemented with appropriate origin checks and state cleanup.

📝 Walkthrough

Walkthrough

The Designify page now provides a responsive settings editor with live preview, save/reset state handling, embedded preview messaging, configurable error-page previews, new styling, and localized editor labels.

Changes

Designify editor

Layer / File(s) Summary
Settings form and preview state contract
app/Filament/Pages/Designify.php, app/Filament/Widgets/PreviewWidget.php, tests/Unit/Filament/Pages/DesignifyTest.php
Settings use titled sections and live tabs. Preview settings are nested from designify: keys. Preview update, save, reset, and reload events are dispatched. The former preview widget is removed.
Responsive editor interface
resources/views/filament/pages/designify.blade.php, resources/css/filament/admin/designify.css, resources/css/filament/admin/theme.css, resources/lang/*/admin/settings.php
The page adds settings and preview panels, dirty-state tracking, save/reset controls, viewport selection, responsive layouts, editor styling, and localization keys.
Embedded preview rendering
resources/scripts/components/App.tsx, resources/views/errors/*.blade.php
Embedded previews receive settings through postMessage. The application and error pages apply preview colors, layout values, text, and images.

There are issues when previewing changes for error pages.

When an error page is customized, the designify preview is refreshed to "Panel Preview" rather than that error page.

Steps to Reproduce:

  • Goto Designify -> Error Pages
  • Make changes to an error page. (Ex; 500) [500 error page should be selected on preview also]
  • When the preview is refreshed, it shows the "panel preview" rather than [500] error page.

LGTM! The live preview integration and postMessage bridge between the Filament admin editor and the client React application are cleanly implemented and secure (origin and window references are properly validated). State syncing, debounced updates, responsive views, and localization fallback entries are well-handled.

🟡 Minor · Clear the unload bypass after reset. · designify.blade.php:82

resources/views/filament/pages/designify.blade.php:82
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clear the unload bypass after reset.

designify-reset sets window.__designifySkipBeforeUnload to true, but no code clears it. After a user resets and edits again, isDirty becomes true while handleBeforeUnload still returns because the global flag remains set. Closing the page can discard those edits without a warning.

Remove this assignment, or clear the flag after the reset operation completes.

Proposed fix
-        x-on:designify-reset.window="isDirty = false; window.__designifySkipBeforeUnload = true"
+        x-on:designify-reset.window="isDirty = false"

@coderabbitai I checked the outside-diff finding about __designifySkipBeforeUnload. Designify::resetToDefaults() dispatches designify-reset and then explicitly runs window.__designifySkipBeforeUnload = true; window.location.reload() (app/Filament/Pages/Designify.php:744–748). This is a full document reload, so the next editor starts with a fresh window and the bypass flag is undefined. Subsequent edits therefore trigger the normal dirty-state warning.

The flag is deliberately temporary to permit the reset reload. Removing it only from the Blade event handler would not change the PHP-dispatched JavaScript, which also sets it immediately before reloading. The reported sequence does not occur in the current reset flow, so I am leaving this behavior unchanged. Please re-evaluate and withdraw the finding if you agree.

@jasonzli-DEV, verification confirms the analysis.

resetToDefaults() dispatches designify-reset, then sets window.__designifySkipBeforeUnload immediately before window.location.reload(). The beforeunload handler checks the flag only in that window. A full reload creates a new window context, so later edits do not retain the bypass flag.

The finding is invalid for this flow. I withdraw it.

Timestamp: 2026-09-21T13:35:39.538Z
Learning: In `app/Filament/Pages/Designify.php`, `Designify::resetToDefaults()` uses `window.__designifySkipBeforeUnload = true` only to bypass the `beforeunload` warning during its immediate full `window.location.reload()`. In `resources/views/filament/pages/designify.blade.php`, the flag is not persistent across that reload, so later dirty edits still trigger the normal warning.
