# Headless Browsers
The library, eschewing unstable and nascent ECMAScript features, plays nicely
with most headless browsers. This demo shows a few common headless scenarios.
NodeJS does not ship with its own layout engine. For advanced HTML exports, a
headless browser is generally indistinguishable from a browser process.
## Chromium Automation with Puppeteer
[Puppeteer](https://pptr.dev/) enables headless Chromium automation.
[`html.js`](./html.js) shows a dedicated script for converting an HTML file to
XLSB using puppeteer. The first argument is the path to the HTML file. The
script writes to `output.xlsb`:
```bash
# read from test.html and write to output.xlsb
$ node html.js test.html
```
The script pulls up the webpage using headless Chromium and adds a script tag
reference to the standalone browser build. That will make the `XLSX` variable
available to future scripts added in the page! The browser context is not able
to save the file using `writeFile`, so the demo generates the XLSB spreadsheet
bytes with the `base64` type, sends the string back to the main process, and
uses `fs.writeFileSync` to write the file.
## WebKit Automation with PhantomJS
This was tested using [PhantomJS 2.1.1](https://phantomjs.org/download.html)
```bash
$ phantomjs phantomjs.js
```
The flow is similar to the Puppeteer flow (scrape table and generate workbook in
website context, copy string back, write string to file from main process).
The `binary` type generates strings that can be written in PhantomJS using the
`fs.write` method with mode `"wb"`.
## wkhtmltopdf
This was tested in wkhtmltopdf 0.12.4, installed using the official binaries:
```bash
$ wkhtmltopdf --javascript-delay 20000 http://oss.sheetjs.com/sheetjs/tests/ test.pdf
```
[The new demo](https://docs.sheetjs.com/docs/getting-started/demos/headless)
has a more focused table export example as well as a demo script for Chromium
automation with Puppeteer and multi-browser automation with Playwright.
