Next.js

SpreadJSは、Windows、Linux、MacなどのさまざまなプラットフォームでWebアプリケーションを開発できる React ベースのフレームワークである Next.jsをサポートします。Next.jsは、TypeScriptのサポート、静的サイトジェネレーター(SSG)/サーバーサイドレンダリング(SSR)、ルートの事前取得、スマートバンドルなど機能を提供します。

詳細については、https://nextjs-ja-translation-docs.vercel.app/docs/getting-startedを参照してください。

このチュートリアルでは、SpreadJS を使用する Next.jsアプリケーションを作成します。

type=warning

メモ:Node.jsのバージョンはV14以降が必要です。

Next.jsアプリを作成する

Next.js アプリケーションを簡単に作成するには、Create Next App ツールを使用します。

  1. コマンドプロンプトまたはターミナルで次のコマンドを実行して、Next.js TypeScriptプロジェクトを作成します。

    npx create-next-app@latest nextjs-with-spreadjs --use-npm

    コマンドが実行されると、プロジェクトの構成の設定を行います。TypeScriptのオプションを有効にしてください。また、作成には時間がかかる場合がありますので、そのままお待ちください。


  2. 次のコマンドを実行します。

    cd nextjs-with-spreadjs

    npm run dev


  3. ブラウザで次のリンクを開きます。Next.jsの公式ページが表示されます。

    http://localhost:3000/


  4. 現在のターミナルを閉じて、Visual Studio Code(または他のIDE)を使用してnextjs-with-spreadjs フォルダを開きます。

SpreadJSをインストールする

  1. SpreadJSパッケージ、および日本語リソースをインストールします。

    npm install @mescius/spread-sheets-react@xx.x.x

    npm install @mescius/spread-sheets-resources-ja@xx.x.x

    type=warning

    'xx.x.x'の部分には製品のバージョンを指定してください。バージョンの指定を省略すると最新バージョンがインストールされますが、日本語版での動作保証は日本語版サイトで公開しているバージョンのみとなります。

  2. アプリケーションのルートフォルダに、「components」フォルダを作成します(componentsフォルダが存在しない場合のみ)。

  3. JavaScript XMLファイル(ファイル名:SpreadSheet.jsx)を「components」フォルダに追加し、次のコードを入力します。

    “use client“;
    
    import React, {  useState } from "react";
    import { SpreadSheets, Worksheet, Column } from "@mescius/spread-sheets-react";
    import * as GC from "@mescius/spread-sheets";
    import '@mescius/spread-sheets-resources-ja';
    
    // カルチャ設定
    GC.Spread.Common.CultureManager.culture('ja-jp');
    
    export default function SpreadSheet() {
    
        const [spreadBackColor, setSpreadBackColor] = useState('aliceblue');
        const [sheetName, setSheetName] = useState('Empolyees');
        const [hostStyle, setHostStyle] = useState({
            width: '100%',
            height: '700px'
        });
        const dataArr = [
            {
                "jobTitleName": "Developer",
                "preferredFullName": "Romin Irani",
                "region": "CA",
                "phoneNumber": "408-1234567"
            },
            {
                "jobTitleName": "Developer",
                "preferredFullName": "Neil Irani",
                "region": "CA",
                "phoneNumber": "408-1111111"
            },
            {
                "jobTitleName": "Program Directory",
                "preferredFullName": "Tom Hanks",
                "region": "CA",
                "phoneNumber": "408-2222222"
            }
        ];
        const [data, setData] = useState(dataArr);
        const [columnWidth, setColumnWidth] = useState(200);
        return (
            <SpreadSheets backColor={spreadBackColor} hostStyle={hostStyle}>
                <Worksheet name={sheetName} dataSource={data}>
                    <Column dataField='preferredFullName' width={columnWidth}></Column>
                    <Column dataField='jobTitleName' width={columnWidth}></Column>
                    <Column dataField='phoneNumber' width={columnWidth}></Column>
                    <Column dataField='region' width={columnWidth}></Column>
                </Worksheet>
            </SpreadSheets>);
    }
  4. app/page.tsxファイルの内容を、次のコードに変更します。

    import dynamic from "next/dynamic";
        
        const SpreadSheet = dynamic(
          () => {
            return import("../components/SpreadSheet");
          },
          { ssr: false }
        );
        
        export default function Home() {
          return (
            <div>
              <h1>
              Next.JS + Spreadsheets demo
              </h1>
              <SpreadSheet />
            </div>
          )
        }

スタイルをインポートする

app フォルダにある globals.css ファイルに次のコードを追加して、SpreadJSの CSS をアプリケーションにインポートします。

@import '@mescius/spread-sheets/styles/gc.spread.sheets.excel2016colorful';

アプリを実行する

npm run dev コマンドを使用してアプリケーションを実行します。デフォルトでは、プロジェクトは http://localhost:3000/ で実行されます。
