在 NextJS 中使用 SpreadJS

SpreadJS 支持 NextJS:一个基于 React 的框架,它可以让你为不同的平台开发 Web 应用程序,如 Windows、Linux 和 Mac。

NextJS 提供生产所需的所有功能,无论是 TypeScript 支持、混合静态和服务器渲染、路由预取还是智能捆绑。

有关详细信息,请参阅 https://nextjs.org/docs/getting-started

在本教程中,我们构建了一个使用 SpreadJS 的 Next.js 应用程序。

type=warning

注意:SpreadJS 现在支持 NextJS 版本 14。要创建 Next.js 应用程序,请确保安装的 Node.js 版本应大于 v18.17。

创建 Next.js 应用程序

创建 Next.js 应用程序的最简单方法是使用创建下一个应用程序工具。

  1. 从命令提示符或终端运行以下命令以创建 Next.js TypeScript 项目。

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

    当终端提示配置信息时,选择需要的选项并回车确认。在终端安装并创建项目时稍等片刻。

  2. 在终端中键入以下命令。

    cd nextjs-with-spreadjs
    npm run dev
  3. 使用浏览器打开以下链接。然后你会看到NextJS的欢迎页面。

    http://localhost:3000/

  4. 关闭当前终端。使用 Visual Studio Code 或 IDE 打开 nextjs-with-spreadjs 文件夹。

安装 SpreadJS

  1. 安装 SpreadJS 包。

    npm install @grapecity-software/spread-sheets-react

    创建一个名为components的文件夹,如果它不存在于应用程序的根文件夹中。

  2. 创建一个名为SpreadSheet.jsx的 JavaScript XML 文件,并将其添加到组件文件夹中,并在其中添加以下代码。

    “use client“;
    
    import React, {  useState } from "react";
    import { SpreadSheets, Worksheet, Column } from "@grapecity-software/spread-sheets-react";
    import * as GC from "@grapecity-software/spread-sheets";
    
    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>);
    }
  3. 更改索引文件内容。用以下代码替换app/page.tsx文件的默认内容。

    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>
      )
    }

导入样式

通过在app文件夹中的globals.css文件中添加以下行,将SpreadJS CSS 导入到应用程序中。

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

运行和测试应用程序

您可以使用 npm run dev 命令运行该应用程序。默认情况下,该项目在 http://localhost:3000/ 运行。
