今回は、バージョンが少し古いNext.js(V13系)のプロジェクト作成とChakraUI(V2系)のインストール方法について書いていきます。
Next.js(V13系)のプロジェクト作成
下記のコマンドを入力します。
npx craete-next-app@13 <プロジェクト名>
各ソフトウェアのインストールについては、各々のプロジェクトに合わせてください。
プロジェクト作成は以上です。
ChakraUI(V2系)のインストール
1. 必要パッケージをインストール
プロジェクトのルートで以下を実行：
npm install @chakra-ui/react@2.8.2 @emotion/react @emotion/styled framer-motion
2. ChakraProvider をラップするレイアウトを作成
Next.js 13 のApp Routerではapp/layout.tsxにChakraProviderを仕込みます。
app/providers.tsx（分離推奨）の作成
app/providers.tsx
// app/providers.tsx
"use client";
import { ChakraProvider } from "@chakra-ui/react";
export function Providers({ children }: { children: React.ReactNode }) {
return <ChakraProvider>{children}</ChakraProvider>;
}
app/layout.tsxの更新
app/layout.tsx
import type { Metadata } from 'next'
import { Inter } from 'next/font/google'
import './globals.css'
import { Providers } from './providers'//追加
const inter = Inter({ subsets: ['latin'] })
export const metadata: Metadata = {
title: 'Create Next App',
description: 'Generated by create next app',
}
export default function RootLayout({
children,
}: {
children: React.ReactNode
}) {
return (
<html lang="en">
<body className={inter.className}>
<Providers>
{children}
</Providers>
</body>
</html>
)
}
3. 実際に Chakra UI コンポーネントを使う
app/page.tsx
import Image from 'next/image'
import {Button} from "@chakra-ui/react"//追加
export default function Home() {
return (
<main className="flex min-h-screen flex-col items-center justify-between p-24">
<Button colorScheme='teal'>Hello Chakra</Button>
<div className="z-10 max-w-5xl w-full items-center justify-between font-mono text-sm lg:flex">
<p className="fixed left-0 top-0 flex w-full justify-center border-b border-gray-300 bg-gradient-to-b from-zinc-200 pb-6 pt-8 backdrop-blur-2xl dark:border-neutral-800 dark:bg-zinc-800/30 dark:from-inherit lg:static lg:w-auto lg:rounded-xl lg:border lg:bg-gray-200 lg:p-4 lg:dark:bg-zinc-800/30">

🔎 よくある注意点
❗ App Router では ChakraProvider を "use client" の中に置く必要があります
→ そのため app/providers.tsx を分ける形式にすると管理しやすい。
❗ page.tsx などで Chakra UI を使用する場合も "use client"; を明示
→ フロント側で動作するライブラリのため。
