## Snowpack
Snowpack works with no caveats.
<details><summary><b>Complete Example</b> (click to show)</summary>
1) Install the tarball using a package manager:
<Tabs>
<TabItem value="npm" label="npm">
<pre><code parentName="pre" {...{"className": "language-bash"}}>{`\
$ npm install --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
</code></pre>
</TabItem>
<TabItem value="pnpm" label="pnpm">
<pre><code parentName="pre" {...{"className": "language-bash"}}>{`\
$ pnpm install --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
</code></pre>
</TabItem>
<TabItem value="yarn" label="Yarn" default>
<pre><code parentName="pre" {...{"className": "language-bash"}}>{`\
$ yarn add --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
</code></pre>
</TabItem>
</Tabs>
2) Save the following to `index.js`:
```js title="index.js"
// highlight-next-line
import { set_fs, utils, version, writeFile } from 'xlsx/xlsx.mjs';
document.getElementById("xport").addEventListener("click", async() => {
/* fetch JSON data and parse */
const url = "https://sheetjs.com/executive.json";
const raw_data = await (await fetch(url)).json();
/* filter for the Presidents */
const prez = raw_data.filter(row => row.terms.some(term => term.type === "prez"));
/* 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 */
writeFile(workbook, "Presidents.xlsx");
});
```
3) Create a small HTML page that loads the script. Save to `index.html`:
```html title="index.html"
<!DOCTYPE html>
<html lang="en">
<head></head>
<body>
<h1>SheetJS Presidents Demo</h1>
<button id="xport">Click here to export</button>
<script type="module" src="./index.js"></script>
</body>
</html>
```
:::note
Unlike other bundlers, Snowpack requires a full page including `HEAD` element.
:::
4) Build for production:
```bash
npx snowpack build
```
5) Start a local HTTP server, then go to http://localhost:8080/
```bash
npx http-server build/
```
Click on "Click here to export" to generate a file.
