SKBE v1.0.1.0 Update: Independent Design Presets, Responsive Sidebar Stacking, and i18n Perfection

1. Introduction: Operational Challenges Identified After v1.0.0.15

Following the release of SvelteKit Blog Engine (SKBE) v1.0.0.15—which introduced the O(1) D1 sidebar snapshot cache and the media URL migration pipeline—we spent time actively operating the admin console across diverse environments, screen resolutions, and languages (Korean, English, and Japanese). During real-world content creation and theme adjustments, several architectural bottlenecks and subtle layout defects came to light.

The v1.0.1.0 update focuses directly on three pillars: design editing safety, responsive visual polish in multilingual UI, and streamlined deployment automation:

1. Eliminating Destructive Database Overwrites in Design Backups: Replaced the legacy full-table drop/replace restore mechanism with an isolated, neutral JSON preset format (design_preset) that backs up individual slots and injects them safely into targeted slots.
2. Fixing Sidebar Element Overflow & CJK Clipping: Resolved horizontal clipping and button cut-offs within narrow sidebars, alongside CJK typography issues where spaceless Japanese text failed to wrap correctly.
3. Dynamic Slot Name Localization: Solved fixed Korean default names ("디자인 슬롯 1") stored in the database by dynamically translating them to match the active admin language (Design Slot 1, デザインスロット 1) in real time.
4. Automated Project Name Synchronization in Deploy Scripts: Added automated pipelines so that package.json deploy commands stay seamlessly synced with the resolved project names during initial setup and multi-account syncs.
5. Real-Time Sidebar Snapshot Sync & Dependency Security Patches: Linked post lifecycle events (create, edit, delete) directly to background D1 snapshot generation, and patched security vulnerabilities in core dependencies.

2. Design Editor: Isolated Slot Preset Backup & Target Slot Restore Architecture

1) Limitations and Risks of the Legacy Approach

Previously, the design backup and restore feature interacted with the /api/restore endpoint by executing a destructive sweep: it completely purged (DELETE FROM) the layouts, widgets, and layout_widgets tables and re-inserted records directly from the uploaded file.

This legacy flow carried serious risks:

• Catastrophic Data Loss: Restoring a single backup file instantly wiped out every layout and widget configuration across all design slots (Slots 1, 2, and 3) without warning.
• No Slot Granularity: Administrators could not isolate a specific theme (such as Slot 2’s Minimalist 1-column layout) into a standalone preset file, nor could they safely import a custom preset from another blog into only Slot 3.
• Lack of Visual Verification Before Commit: Restoring immediately committed changes to the production database, leaving no opportunity to preview or rollback incorrect backup uploads.

2) The New Architecture: Neutral Design Preset (design_preset) Pipeline

We completely retired the full-database sweep and introduced an isolated, neutral preset architecture integrated directly with the editor’s reactive in-memory state (slots).

// Extracts pure visual and layout data as a neutral preset
const presetData = {
    version: "3.0",
    backupType: "design_preset",
    timestamp: new Date().toISOString(),
    presetName: slotName,
    design: {
        theme: snapshot.theme,
        header: snapshot.header,
        footer: snapshot.footer,
        site_title: snapshot.site_title,
        widget_shadow_global: snapshot.widget_shadow_global,
        layout: snapshot.layout,
        widgets: snapshot.widgets
    }
};

Key Advantages of the New Preset System

• Neutral Slot Association: Presets contain zero hardcoded slot identifiers (slot1, slot2, etc.). A preset exported from Slot 1 can be freely imported into Slot 2, Slot 3, or any future slot without conflict.
• Unsaved In-Memory State Retention: When exporting the currently active slot, the system captures real-time, unpersisted editor edits (getSnapshotOfCurrentSlot()), ensuring the download contains the exact state visible on screen.
• Preview-First 2-Stage Safe Injection: When a file is uploaded and a target slot is selected, the data is injected strictly into the editor's reactive memory state first. The live preview updates immediately, and changes are committed to D1 only when the user explicitly clicks [Apply to Blog] or [Save Current Settings].
• Legacy Backup Compatibility (convertLegacyBackupToPreset): An automated parser detects whether an imported file uses the new preset format or a legacy database table dump, seamlessly normalizing legacy data into the modern slot schema.

3. Responsive Sidebar Stacking & Multilingual (i18n) Perfection

1) Resolving Sidebar Button Clipping with Full-Width Stacking

The administrator sidebar provides an effective content width of approximately 260px–290px after padding. Previously, slot select dropdowns and action buttons were placed side by side in a single horizontal row (flex-row).

Because the dropdown consumed default space, action buttons were pushed off the right boundary—clipping download button labels and pushing the restore confirmation button completely off-screen.

We restructured the layout into a responsive vertical stack (flex-col, w-full):

<!-- Backup section: full-width vertical stack -->
<div class="setting-control flex flex-col gap-2 w-full">
    <select class="select-field w-full" bind:value={slotBackupTargetId}>...</select>
    <button class="btn-primary w-full flex items-center justify-center gap-2">
        <Download size={16} />
        <span>Download Slot Backup</span>
    </button>
</div>

With each control occupying its own 100% width row, buttons align neatly within the panel regardless of how narrow the sidebar becomes.

2) Debugging Japanese Typography and 18-Character Katakana Button Overflow

During multilingual validation, we encountered visual defects that occurred exclusively in the Japanese locale. Thorough investigation revealed two distinct root causes:

Root Cause A: Spaceless Japanese Sentences vs word-break: keep-all

• Symptom: Hint descriptions (各スロットのデザインを独立したファイルとしてエ...) overflowed the container, truncating text on the right.
• Cause: Korean words are separated by spaces, allowing keep-all to wrap cleanly at word boundaries. However, written Japanese contains no spaces. When keep-all was applied, browsers treated entire sentences as single unbroken words and refused to wrap.
• Solution: Replaced keep-all with overflow-wrap: anywhere; word-break: break-word;, allowing Japanese characters to wrap naturally at any character boundary without spilling outside the container.

Root Cause B: Legacy CSS width: auto !important; vs 18-Character Katakana

• Symptom: The Japanese backup button (スロットバックアップをダウンロード) protruded more than 50px past the white card border.
• Cause: A legacy CSS rule (.setting-control .btn-primary { width: auto !important; }) overrode our w-full class. While the Korean label (슬롯 백업 다운로드, 9 characters) was short enough to fit, the Japanese Katakana translation was 18 characters long. Under width: auto !important;, the button's intrinsic width expanded past 320px, far exceeding the 260px available sidebar width.
• Solution: Updated the CSS selector to .setting-control .btn-primary:not(.w-full) to lift the !important restriction, and applied style="width: 100% !important; max-width: 100%; white-space: normal; word-break: break-word;" to ensure the button adapts cleanly to 100% width and wraps text internally when necessary.

3) Real-Time Dynamic Slot Name Localization (getSlotDisplayName)

Because default slot names ("디자인 슬롯 1", "미니멀 1열", "다크 모던") are persisted in D1 as Korean strings during initial setup, switching the admin interface to English or Japanese previously left Korean names inside the select options.

We introduced the getSlotDisplayName helper function. It preserves any custom names entered by users while dynamically translating standard defaults into the active language (adminLang.value):

• Korean: 슬롯 1 (디자인 슬롯 1)
• English: Slot 1 (Design Slot 1)
• Japanese: スロット 1 (デザインスロット 1)

4. Deployment & Multi-Account Automation: Project Name Sync Pipeline

SKBE features a multi-account deployment architecture (scripts/deploy-multi.js) that allows blogs and admin consoles to be distributed across distinct Cloudflare accounts.

Previously, whether setting up a new instance manually or generating random project names automatically (setup.js), the --project-name arguments inside package.json deploy commands (deploy:blog, deploy:admin) had to be adjusted by hand.

We added the updatePackageJsonDeployScripts pipeline to scripts/setup.js and scripts/sync-accounts.js:

• The resolved project names automatically update inside package.json during both manual and automated installation flows.
• Running npm run deploy:sync guarantees that the main account project names in .deploy-accounts.json and the scripts in package.json remain perfectly synchronized.

5. Engine Optimization and Dependency Security

1. Real-Time Sidebar Snapshot Synchronization:
   • The O(1) sidebar snapshot introduced in v1.0.0.15 is now triggered asynchronously (generateSidebarSnapshot) upon post creation (new), modification ([id]), and deletion/status changes (posts), keeping edge D1 caches fresh without blocking user responses.
2. Media URL Migration Path Broadening:
   • Upgraded the regular expression and query in /api/media/migrate-urls to detect and rewrite proxy URLs stored in posts/ subfolders or custom directory hierarchies.
3. Security Patches & Zod v4 Version Pinning:
   • Updated better-auth and tiptap packages to patched versions, and locked zod strictly to the v4 branch via pnpm overrides to ensure build reproducibility.
