## Browserify
`browserify` is compatible with the library and should "just work" with the
`require` form in a main page or in a web worker:
```js
var XLSX = require("xlsx");
// ... use XLSX ...
```
[After installing the module](../../installation/nodejs), bundling is easy:
```bash
browserify app.js > browserify.js
uglifyjs browserify.js > browserify.min.js
```
Web Worker scripts can be bundled using the same approach.

1) Install the tarball using a package manager:

<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) Download the following files:
- [`app.js`](pathname:///browserify/app.js)
- [`index.html`](pathname:///browserify/index.html)
- [`xlsxworker.js`](pathname:///browserify/xlsxworker.js)
3) Bundle the scripts:
```bash
npx browserify app.js > browserify.js
npx browserify xlsxworker.js > worker.js
```
4) Spin up a local web server:
```
npx http-server
```
5) Access the site <http://localhost:8080/> and use the file input element to
select a spreadsheet.
