## Rollup
|
||||
|
||||
Rollup requires `@rollup/plugin-node-resolve` to support NodeJS modules:
|

<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 i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} rollup @rollup/plugin-node-resolve
|
||||
</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`} rollup @rollup/plugin-node-resolve
|
||||
</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`} rollup @rollup/plugin-node-resolve
|
||||
</code></pre>
|
||||
</TabItem>
|
||||
</Tabs>
|
||||
|
||||
2) Save the following to `index.js`:
|
||||
|
||||
```js title="index.js"
|
||||
// highlight-next-line
|
||||
import { utils, version, writeFileXLSX } 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 */
|
||||
writeFileXLSX(workbook, "Presidents.xlsx");
|
||||
});
|
||||
```
|
||||
|
||||
3) Bundle the script:
|
||||
|
||||
```bash
|
||||
npx rollup index.js --plugin @rollup/plugin-node-resolve --file bundle.js --format iife
|
||||
```
|
||||
|
||||
4) Create a small HTML page that loads the script. Save to `index.html`:
|
||||
|
||||
```html title="index.html"
|
||||
<!DOCTYPE html>
|
||||
<html lang="en">
|
||||
<head></head>

<button id="xport">Click here to export</button>
|
||||
<script type="module" src="./bundle.js"></script>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
|
||||
5) Start a local HTTP server, then go to http://localhost:8080/
|
||||
|
||||
```bash
|
||||
npx http-server .
|
||||
```
|
||||
|
||||
Click on "Click here to export" to generate a file.
