Documentation

1. richtpl.tsx Setup Guide

1. Place richtpl.tsx at the root of your project

Place the template configuration file richtpl.tsx in the root of your project. This file configures the internationalization and theme settings of the site.

export default {
  title: "My Project",
  tagline: "The best project ever!",
  url: "https://myproject.com",
  organizationName: "MyOrganization",
  projectName: "my-project",
  i18n: {
    defaultLocale: "en",
    locales: ["en", "ja"],
    localeConfigs: {
      en: { label: "English", htmlLang: "en", path: "en" },
      ja: { label: "日本語", htmlLang: "ja", path: "ja" },
    },
  },
  themeConfig: {
    colorMode: {
      defaultMode: "light",
      selectSwitch: true,
    },
    header: {
      title: "My Project",
      logo: {
        href: "/",
        type: "Vercel&Next.js",
      },
    },
    footer: {
      title: "My Footer",
      social: {
        github: true,
        twitter: "my_twitter_handle",
      },
    },
  },
};

2. i18n Configuration

• defaultLocale specifies the default language used.
• locales defines an array of supported languages, while localeConfigs provides settings for each language.
• The path sets the URL prefix. For example, the Japanese page will be redirected to /ja.

3. Theme Settings

• colorMode controls the switching between dark mode and system-based themes.
• The header and footer sections configure the logo and navigation in the site's header and footer.

2. middleware.ts Setup Guide

1. Locale Middleware Setup

To enable internationalization using next-intl, configure locale handling in middleware.ts. This middleware applies the appropriate language settings based on the URL.

import createMiddleware from "next-intl/middleware";
import { locales, localePrefix, pathnames } from "@/components/provider/nav";
import richtplConfig from "../richtpl.config";
import { NextRequest, NextResponse } from "next/server";

const intlMiddleware = createMiddleware({
  locales,
  localePrefix,
  pathnames,
  defaultLocale: richtplConfig.i18n.defaultLocale,
});

export function middleware(request: NextRequest) {
  let response = intlMiddleware(request);
  if (!response) {
    response = NextResponse.next();
  }
  response.headers.set("x-pathname", request.nextUrl.pathname);
  return response;
}

export const config = {
  matcher: ["/", `/(ja|en)/:path*`],
};

2. Matcher Configuration

• The matcher defines the URL patterns processed by the middleware. The pattern /(ja|en)/:path* covers both English and Japanese pages.
• If other languages are added, they must be included in the matcher as well.

Example of Theme Switching and i18n Implementation

import { useState } from "react";
import { useTheme } from "next-themes";
import { useTranslations } from "next-intl";

export default function Header() {
  const { theme, setTheme } = useTheme();
  const t = useTranslations("Header");

  return (
    <header>
      <h1>{t("title")}</h1>
      <button onClick={() => setTheme(theme === "light" ? "dark" : "light")}>
        {theme === "light" ? "dark mode" : "light mode"}
      </button>
    </header>
  );
}

• This code implements a button to toggle themes and displays i18n-supported text.

FAQ

Q: How can I add other languages?

A: To add a new language, update the i18n configuration in richtpl.tsx by adding the language to the locales array and providing corresponding settings in localeConfigs. Additionally, update the matcher in middleware.ts to include the new language.

Q: How can I customize theme switching?

A: You can customize the default theme and toggle options in the themeConfig.colorMode settings. Additionally, you can dynamically switch themes using the useTheme hook.
