Architecture

• frontend/: SvelteKit 2 + Svelte 5 app with Tailwind CSS v4, static adapter
• backend/: Bun + Elysia API server with Drizzle ORM + PostgreSQL

Commands

Task	Frontend (cd frontend)	Backend (cd backend)
Dev	bun run dev	bun --watch src/index.ts
Build	bun run build	bun build src/index.ts --target bun --outdir ./dist
Lint	bun run lint	—
Format	bun run format	—
Typecheck	bun run check	—
Test	—	bun test (single: bun test <file>)

Code Style

• Use tabs, single quotes, no trailing commas (Prettier configured in frontend)
• Frontend: Svelte 5 runes, TypeScript strict, Lucide icons
• Backend: Drizzle schemas in schemas/, snake_case for DB columns, camelCase in TS
• No comments unless complex; no // @ts-expect-error or as any

UI Style Guide

Buttons

All buttons should follow these patterns:

Primary Button (filled)

class="px-4 py-2 bg-black text-white rounded-full font-bold hover:bg-gray-800 transition-all duration-200 disabled:opacity-50 cursor-pointer"

Secondary Button (outlined) - Navigation/Action buttons

class="px-4 py-2 border-4 border-black rounded-full font-bold hover:border-dashed transition-all duration-200 disabled:opacity-50 cursor-pointer"

Toggle/Filter Button (selected state)

class="px-4 py-2 border-4 border-black rounded-full font-bold transition-all duration-200 cursor-pointer {isSelected
    ? 'bg-black text-white'
    : 'hover:border-dashed'}"

Cards & Containers

class="border-4 border-black rounded-2xl p-6 hover:border-dashed transition-all"

Inputs

class="w-full px-4 py-2 border-2 border-black rounded-lg focus:outline-none focus:border-dashed"

Modals

class="bg-white rounded-2xl w-full max-w-lg p-6 border-4 border-black max-h-[90vh] overflow-y-auto"

Confirmation Modals

Use the ConfirmModal component from $lib/components/ConfirmModal.svelte or follow this pattern:

Backdrop

<div
    class="fixed inset-0 bg-black/50 z-50 flex items-center justify-center p-4"
    onclick={(e) => e.target === e.currentTarget && onCancel()}
    onkeydown={(e) => e.key === 'Escape' && onCancel()}
    role="dialog"
    tabindex="-1"
>

Modal Container

class="bg-white rounded-2xl w-full max-w-md p-6 border-4 border-black"

Title

<h2 class="text-2xl font-bold mb-4">{title}</h2>

Message

<p class="text-gray-600 mb-6">{message}</p>

Button Row

<div class="flex gap-3">
    <!-- Cancel button (secondary) -->
    <button class="flex-1 px-4 py-2 border-4 border-black rounded-full font-bold hover:border-dashed transition-all duration-200 disabled:opacity-50 cursor-pointer">
        cancel
    </button>
    <!-- Confirm button (primary/success/warning/danger) -->
    <button class="flex-1 px-4 py-2 bg-black text-white rounded-full font-bold border-4 border-black hover:border-dashed transition-all duration-200 disabled:opacity-50 cursor-pointer">
        confirm
    </button>
</div>

Confirm Button Variants

• Primary: bg-black text-white
• Success: bg-green-600 text-white
• Warning: bg-yellow-500 text-white
• Danger: bg-red-600 text-white

Do NOT use browser alert() or confirm(). Always use styled modals.

Key Patterns

• Border style: border-4 for buttons, border-2 for inputs, border-4 for cards/containers
• Rounding: rounded-full for buttons, rounded-2xl for cards, rounded-lg for inputs
• Hover state: hover:border-dashed for outlined elements
• Focus state: focus:border-dashed for inputs
• Selected state: bg-black text-white (filled)
• Animation: Always include transition-all duration-200
• Colors: Black borders, white backgrounds, no colors except for errors (red)
• Cursor: Always include cursor-pointer on clickable elements (buttons, links, interactive cards)
• Disabled cursor: Always include disabled:cursor-not-allowed on buttons that can be disabled
