使用 ViteJS 打包表单

ViteJS 是一个用于生成静态站点的现代构建工具。

¥ViteJS is a modern build tool for generating static sites.

SheetJS 是一个用于从电子表格读取和写入数据的 JavaScript 库。

¥SheetJS is a JavaScript library for reading and writing data from spreadsheets.

本 demo 使用 ViteJS 和 SheetJS 导出数据。我们将探讨如何使用 ViteJS 将 SheetJS 添加到网站以及如何将数据导出到电子表格。

¥This demo uses ViteJS and SheetJS to export data. We'll explore how to add SheetJS to a site using ViteJS and how to export data to spreadsheets.

内容演示的 Vite 部分涵盖资源加载器。它们非常适合静态站点在构建时从工作表中提取数据。

¥The Vite section of the Content demo covers asset loaders. They are ideal for static sites pulling data from sheets at build time.

该演示重点介绍与 ViteJS 打包器的集成细节。

¥This demo focuses on integration details with the ViteJS bundler.

这些演示遵循 "导出教程"，其中更详细地介绍了 SheetJS 库的用法。

¥The demos follow the "Export Tutorial", which covers SheetJS library usage in more detail.

测试部署

本 demo 在以下环境下进行了测试：

¥This demo was tested in the following environments:

ViteJS	日期
`5.2.10`	2024-04-27
`4.5.3`	2024-04-27
`3.2.10`	2024-04-27

集成详情

¥Integration Details

"构架" 章节涵盖了 Yarn 和其他包管理器的安装。

¥The "Frameworks" section covers installation with Yarn and other package managers.

在 ViteJS 项目中安装 SheetJS 模块后，import 语句可以加载库的相关部分。

¥After installing the SheetJS module in a ViteJS project, import statements can load relevant parts of the library.

import { read, utils, writeFileXLSX } from 'xlsx';

ViteJS 需要第三方库提供额外的 package.json 元数据。SheetJS 库版本 0.18.10 添加了所需的元数据。

¥ViteJS requires third-party libraries to provide additional package.json metadata. SheetJS library version 0.18.10 added the required metadata.

强烈推荐给升级到最新版本

¥It is strongly recommended to upgrade to the latest version

完整示例

¥Complete Example

创建一个新的 ViteJS 项目：

¥Create a new ViteJS project:

npm create vite@latest sheetjs-vite -- --template vue-ts
cd sheetjs-vite
npm i

添加 SheetJS 依赖：

¥Add the SheetJS dependency:

npm i --save https://cdn.sheetjs.com/xlsx-0.20.3/xlsx-0.20.3.tgz

将 src\components\HelloWorld.vue 替换为：

¥Replace src\components\HelloWorld.vue with:

src\components\HelloWorld.vue
<script setup lang="ts">
import { version, utils, writeFileXLSX } from 'xlsx';

interface President {
  terms: { "type": "prez" | "viceprez"; }[];
  name: { first: string; last: string; }
  bio: { birthday: string; }
}

async function xport() {
/* fetch JSON data and parse */
const url = "https://xlsx.nodejs.cn/executive.json";
const raw_data: President[] = await (await fetch(url)).json();

/* filter for the Presidents */
const prez = raw_data.filter(row => row.terms.some(term => term.type === "prez"));

/* sort by first presidential term */
prez.forEach(row => row.start = row.terms.find(term => term.type === "prez").start);
prez.sort((l,r) => l.start.localeCompare(r.start));

/* flatten objects */
const rows = prez.map(row => ({
  name: row.name.first + " " + row.name.last,
  birthday: row.bio.birthday
}));

/* generate worksheet and workbook */
const worksheet = utils.json_to_sheet(rows);
const workbook = utils.book_new();
utils.book_append_sheet(workbook, worksheet, "Dates");

/* fix headers */
utils.sheet_add_aoa(worksheet, [["Name", "Birthday"]], { origin: "A1" });

/* calculate column width */
const max_width = rows.reduce((w, r) => Math.max(w, r.name.length), 10);
worksheet["!cols"] = [ { wch: max_width } ];

/* create an XLSX file and try to save to Presidents.xlsx */
writeFileXLSX(workbook, "Presidents.xlsx");
}

</script>

<template>
  <button type="button" @click="xport">Export with SheetJS version {{ version }}</button>
</template>

启动开发服务器：

¥Start the development server:

npm run dev

打开 http://localhost:5173/ 的 Web 浏览器并单击导出按钮。

¥Open a web browser to http://localhost:5173/ and click the export button.
搭建生产站点：

¥Build the production site:

npx vite build

通过在 dist 文件夹中运行本地 Web 服务器来验证新站点：

¥Verify the new site by running a local web server in the dist folder:

npx http-server dist

在 Web 浏览器中访问显示的 URL（通常为 http://localhost:8080），然后单击导出按钮。

¥Access the displayed URL (typically http://localhost:8080) in a web browser and click the export button.
