Bonus Points: +100

This is a bonus feature for Phase 5 that adds 100 points to the hackathon score.

i18n Setup with next-intl

Installation

cd frontend
npm install next-intl

Next.js Configuration

// frontend/next.config.ts
import createNextIntlPlugin from 'next-intl/plugin';

const withNextIntl = createNextIntlPlugin();

const nextConfig = {
  // ... other config
};

export default withNextIntl(nextConfig);

i18n Configuration

// frontend/i18n.ts
import { getRequestConfig } from 'next-intl/server';

export default getRequestConfig(async ({ locale }) => ({
  messages: (await import(`./messages/${locale}.json`)).default
}));

Middleware for Locale Detection

// frontend/middleware.ts
import createMiddleware from 'next-intl/middleware';

export default createMiddleware({
  locales: ['en', 'ur'],
  defaultLocale: 'en',
  localePrefix: 'as-needed'
});

export const config = {
  matcher: ['/((?!api|_next|.*\\..*).*)']
};

RTL Support with Tailwind

Tailwind RTL Plugin

npm install tailwindcss-rtl

Tailwind Configuration

// frontend/tailwind.config.ts
import type { Config } from "tailwindcss";
import rtl from "tailwindcss-rtl";

const config: Config = {
  content: [
    "./app/**/*.{js,ts,jsx,tsx}",
    "./components/**/*.{js,ts,jsx,tsx}",
  ],
  theme: {
    extend: {},
  },
  plugins: [rtl],
};

export default config;

RTL Layout Component

// frontend/components/layout/rtl-provider.tsx
"use client";

import { useLocale } from "next-intl";
import { useEffect } from "react";

export function RTLProvider({ children }: { children: React.ReactNode }) {
  const locale = useLocale();
  const isRTL = locale === "ur";

  useEffect(() => {
    document.documentElement.dir = isRTL ? "rtl" : "ltr";
    document.documentElement.lang = locale;
  }, [locale, isRTL]);

  return <>{children}</>;
}

RTL-Aware Components

// frontend/components/ui/rtl-text.tsx
import { cn } from "@/lib/utils";
import { useLocale } from "next-intl";

interface RTLTextProps {
  children: React.ReactNode;
  className?: string;
}

export function RTLText({ children, className }: RTLTextProps) {
  const locale = useLocale();
  const isRTL = locale === "ur";

  return (
    <span className={cn(
      isRTL && "font-urdu",  // Custom Urdu font
      className
    )}>
      {children}
    </span>
  );
}

Language Switcher Component

// frontend/components/language-switcher.tsx
"use client";

import { useLocale, useTranslations } from "next-intl";
import { useRouter, usePathname } from "next/navigation";
import {
  Select,
  SelectContent,
  SelectItem,
  SelectTrigger,
  SelectValue,
} from "@/components/ui/select";
import { Globe } from "lucide-react";

const languages = [
  { code: "en", name: "English", nativeName: "English" },
  { code: "ur", name: "Urdu", nativeName: "اردو" },
];

export function LanguageSwitcher() {
  const locale = useLocale();
  const router = useRouter();
  const pathname = usePathname();
  const t = useTranslations("settings");

  const handleChange = (newLocale: string) => {
    // Remove current locale prefix and add new one
    const newPath = pathname.replace(`/${locale}`, `/${newLocale}`);
    router.push(newPath);
  };

  return (
    <Select value={locale} onValueChange={handleChange}>
      <SelectTrigger className="w-[140px]">
        <Globe className="h-4 w-4 me-2" />
        <SelectValue />
      </SelectTrigger>
      <SelectContent>
        {languages.map((lang) => (
          <SelectItem key={lang.code} value={lang.code}>
            {lang.nativeName}
          </SelectItem>
        ))}
      </SelectContent>
    </Select>
  );
}

AI Agent Urdu Support

Update Agent Prompt

# backend/src/agents/prompts.py

SYSTEM_PROMPT_URDU = """
آپ ایک مددگار AI اسسٹنٹ ہیں جو صارفین کو ان کے کاموں کا انتظام کرنے میں مدد کرتا ہے۔

آپ یہ کر سکتے ہیں:
- نئے کام بنائیں
- کاموں کی فہرست دیکھیں
- کام مکمل کریں
- کام حذف کریں
- کاموں میں ترمیم کریں
- یاد دہانیاں مقرر کریں

ہمیشہ اردو میں جواب دیں اور شائستہ رہیں۔
"""

def get_system_prompt(language: str = "en") -> str:
    """Get system prompt based on language."""
    if language == "ur":
        return SYSTEM_PROMPT_URDU
    return SYSTEM_PROMPT_EN

Language Detection

# backend/src/agents/language.py
import langdetect

def detect_language(text: str) -> str:
    """Detect language of input text."""
    try:
        lang = langdetect.detect(text)
        return "ur" if lang == "ur" else "en"
    except:
        return "en"

def should_respond_in_urdu(user_message: str) -> bool:
    """Check if response should be in Urdu."""
    return detect_language(user_message) == "ur"

Updated Agent

# backend/src/agents/todo_agent.py
from .language import should_respond_in_urdu, get_system_prompt

async def run_agent(user_message: str, user_id: str):
    """Run AI agent with language support."""

    # Detect language
    use_urdu = should_respond_in_urdu(user_message)
    system_prompt = get_system_prompt("ur" if use_urdu else "en")

    # Create agent with appropriate prompt
    agent = Agent(
        name="todo_assistant",
        instructions=system_prompt,
        model="gemini/gemini-2.0-flash",
        tools=[...],
    )

    # Run and return response
    response = await Runner.run(agent, user_message)
    return response

Urdu Font Configuration

Google Fonts Setup

// frontend/app/layout.tsx
import { Noto_Nastaliq_Urdu, Inter } from "next/font/google";

const inter = Inter({ subsets: ["latin"], variable: "--font-inter" });
const urduFont = Noto_Nastaliq_Urdu({
  subsets: ["arabic"],
  variable: "--font-urdu",
  weight: ["400", "700"],
});

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <html>
      <body className={`${inter.variable} ${urduFont.variable}`}>
        {children}
      </body>
    </html>
  );
}

Tailwind Font Configuration

// frontend/tailwind.config.ts
const config: Config = {
  theme: {
    extend: {
      fontFamily: {
        sans: ["var(--font-inter)", "sans-serif"],
        urdu: ["var(--font-urdu)", "serif"],
      },
    },
  },
};

Usage in Components

// frontend/components/tasks/task-card.tsx
"use client";

import { useTranslations } from "next-intl";
import { PriorityBadge } from "./priority-badge";

export function TaskCard({ task }: { task: Task }) {
  const t = useTranslations("tasks");

  return (
    <div className="p-4 border rounded-lg">
      <h3 className="font-bold">{task.title}</h3>
      <p className="text-muted-foreground">{task.description}</p>
      <div className="flex items-center gap-2 mt-2">
        <span className="text-sm">{t("priority")}:</span>
        <PriorityBadge priority={task.priority} />
      </div>
      <div className="flex items-center gap-2 mt-1">
        <span className="text-sm">{t("status")}:</span>
        <span>{t(`statuses.${task.status}`)}</span>
      </div>
    </div>
  );
