Compose Middleware (i18n + auth) +Compose next-intl middleware with our existing auth checks. Keep i18n first, then apply auth to the path without the locale prefix. +```typescript +// middleware.ts +import createMiddleware from 'next-intl/middleware' +import {locales, defaultLocale, type Locale} from './i18n.config' +import {NextResponse} from 'next/server' +import type {NextRequest} from 'next/server' + +const intl = createMiddleware({ + locales, + defaultLocale, + localePrefix: 'as-needed' // Show locale in URL when not default +}) + +const PROTECTED_PATHS = ['/saved', '/profile'] as const +const MIXED_AUTH_PATHS = ['/api/parties', '/p/'] as const + +export default function middleware(request: NextRequest) { + // Run next-intl first (handles locale detection, redirects, etc.) + const intlResponse = intl(request) + if (intlResponse) return intlResponse + + const {pathname} = request.nextUrl + const seg = pathname.split('/')[1] + const pathWithoutLocale = locales.includes(seg as Locale) + ? pathname.slice(seg.length + 1) || '/' + : pathname + + const isProtectedPath = PROTECTED_PATHS.some( + (p) => pathWithoutLocale === p || pathWithoutLocale.startsWith(p + '/') + ) + const isMixedAuthPath = MIXED_AUTH_PATHS.some( + (p) => pathWithoutLocale === p || pathWithoutLocale.startsWith(p) + ) + + const needsAuth = + isProtectedPath || (isMixedAuthPath && ['POST', 'PUT', 'DELETE'].includes(request.method)) + + if (!needsAuth) return NextResponse.next() + + const accountCookie = request.cookies.get('account') + if (!accountCookie?.value) { + if (pathWithoutLocale.startsWith('/api/')) { + return NextResponse.json({error: 'Authentication required'}, {status: 401}) + } + // Preserve locale in redirect + const url = request.nextUrl.clone() + url.pathname = '/teams' + return NextResponse.redirect(url) + } + + try { + const account = JSON.parse(accountCookie.value) + if (!account.token) { + if (pathWithoutLocale.startsWith('/api/')) { + return NextResponse.json({error: 'Authentication required'}, {status: 401}) + } + const url = request.nextUrl.clone() + url.pathname = '/teams' + return NextResponse.redirect(url) + } + } catch { + if (pathWithoutLocale.startsWith('/api/')) { + return NextResponse.json({error: 'Authentication required'}, {status: 401}) + } + const url = request.nextUrl.clone() + url.pathname = '/teams' + return NextResponse.redirect(url) + } + + return NextResponse.next() +} + +export const config = { + matcher: ['/((?!_next|_vercel|.*\\..*).*)'] +} +``` + +### 4. Localized Layout (App Router) +Create `/app/[locale]/layout.tsx` and place `NextIntlClientProvider` here.

The locale-specific layout above should own ``/``. + +### 5. Locale-Aware Navigation +Replace `next/link` and `next/navigation` with `next-intl/navigation` to preserve locale on navigation. +```typescript +// Before +import Link from 'next/link' +import {useRouter, usePathname, useSearchParams} from 'next/navigation' + +// After +import {Link, useRouter, usePathname, useSearchParams} from 'next-intl/navigation' +``` + +### 6. Update Component Imports +Change all translation imports from: +```typescript +import { useTranslation } from 'next-i18next' +import { Trans } from 'next-i18next' +``` + +To: +```typescript +import { useTranslations } from 'next-intl' +// Note: Trans component usage will need to be refactored +``` + +### 7. Update Translation Hook Usage +Change from: +```typescript +const { t } = useTranslation('common') +// Usage: t('party.segmented_control.characters') +``` + +To: +```typescript +const t = useTranslations('common') +// Usage: t('party.segmented_control.characters') +``` + +### 8. Update Trans Component Usage +The `Trans` component works differently in next-intl. Change from: +```typescript + + Are you sure you want to remove{' '} + {{ weapon: gridSummon?.object.name[locale] }} from + your team? + +``` + +To using rich text formatting: +```typescript +t.rich('modals.summons.messages.remove', { + weapon: gridSummon?.object.name[locale], + strong: (chunks) => {chunks} +}) +``` + +### 9. Language Switch +Prefer path-based locale switching over cookie+refresh for clarity and correct URL behavior. +```typescript +// Using next-intl/navigation +const router = useRouter() +const pathname = usePathname() + +function changeLanguage(to: 'en'|'ja') { + router.replace(pathname, {locale: to}) +} +``` +You may still set `NEXT_LOCALE` for persistence, but the router option should be the source of truth. + +### 10.

It currently runs on Next.js 14 using a hybrid of App Router and legacy Pages, with `next-intl` for i18n, Valtio for state, Radix-based UI wrappers, and Tiptap for rich text. The backend is a Rails API and will not change. + +## Problem / Opportunity +- The UI layer carries Next-specific complexity (hybrid routing, middleware composition, Valtio, React wrappers around primitives) for a scope that aligns well with SvelteKit’s simpler mental model. +- Svelte 5 (Runes) and SvelteKit provide small, fast bundles and ergonomic state management for highly interactive UIs like the party editor. +- A rewrite would impose upfront cost but could yield better performance, maintainability, and developer experience. + +## Goals +- Achieve feature and URL parity (including localized routing and auth/method guards) with the current Next.js app. +- Reuse domain types, data contracts, and i18n content; minimize churn to the Rails API layer. +- Maintain or improve perceived performance, accessibility, and UX of primitives (menus, dialogs, tooltips, toasts). + +## Non‑Goals +- No changes to the Rails API endpoints, auth semantics, or data shape. +- No new product features beyond parity (performance and a11y improvements are in scope). + +## Current State (Summary) +- Framework: Next.js 14 with `app/` and `pages/` side by side. +- Routing/i18n: `app/[locale]/…` with `next-intl` and “as-needed” default-locale prefixing; middleware composes i18n with auth/method guards. +- State: Valtio global stores for `accountState` and `appState` (party/grid/editor flows). +- Data: axios-based `utils/api.tsx`, app route handlers under `app/api/**` proxy to Rails; server helpers in `app/lib/*` with zod validation. +- UI: Components under `components/**` using SCSS modules, Radix-based wrappers, custom editor based on Tiptap React + custom extensions. +- URL State: `nuqs` binds filters to query params. +- Storybook: React/Next preset. + +## Feature/Parity Requirements +- Public routes: `/`, `/new`, `/teams`, `/p/[party]` (+ tab segments), `/[username]`, `/about`, `/updates`, `/roadmap` with locale variants under `/ja` and default-locale “as-needed” behavior. +- Auth/method gates: protect `/saved` and `/profile`; 401 JSON for unauthorized API mutations; preserve method-based rules under `/api/**`. +- Party editor: weapons/summons/characters, job/skills/accessory, guidebooks, toggles, remix/delete, editability rules by cookie/user. +- Search & filters: team discovery with element/raid/recency, advanced filters from cookie, pagination (append/replace). +- i18n: reuse JSON namespaces; preserve current translation keys and locale cookie behavior. +- Primitives: dropdown menu, dialog, tooltip, toast, popover, select, switch, slider, command, segmented control with keyboard a11y. +- Editor: Tiptap with mentions, link, lists, headings, youtube, highlight, placeholder. + +## Proposed Direction +Rebuild the web app on SvelteKit 2 and Svelte 5 Runes.
