## SWC
SWC provides `spack` for bundling scripts.
<details><summary><b>Complete Example</b> (click to show)</summary>
1) Install the dependencies using a package manager:
<Tabs>
<TabItem value="npm" label="npm">
<pre><code parentName="pre" {...{"className": "language-bash"}}>{`\
$ npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} regenerator-runtime @swc/cli @swc/core
</code></pre>
</TabItem>
<TabItem value="pnpm" label="pnpm">
<pre><code parentName="pre" {...{"className": "language-bash"}}>{`\
$ pnpm install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} regenerator-runtime @swc/cli @swc/core
</code></pre>
</TabItem>
<TabItem value="yarn" label="Yarn" default>
<pre><code parentName="pre" {...{"className": "language-bash"}}>{`\
$ yarn add https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} regenerator-runtime @swc/cli @swc/core
</code></pre>
</TabItem>
</Tabs>
:::note
The `regenerator-runtime` dependency is used for transpiling `fetch` and is not
required if the interface code does not use `fetch` or Promises.
:::
2) Save the following to `index.js`:
```js title="index.js"
import { utils, version, writeFileXLSX } from 'xlsx';
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 */
writeFileXLSX(workbook, "Presidents.xlsx");
});
```
3) Create an `spack.config.js` config file:
```js title="spack.config.js"
const { config } = require('@swc/core/spack');
module.exports = ({
entry: {
'web': __dirname + '/index.js',
},
output: {
path: __dirname + '/lib'
},
module: {},
});
```
4) Build for production:
```bash
npx spack
```
This command will create the script `lib/web.js`
5) Create a small HTML page that loads the generated script:
```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 src="lib/web.js"></script>
</body>
</html>
```
6) 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.
