## What it is
Grover is a Ruby gem that converts HTML (or a URL) into PDFs, PNGs, or JPEGs by driving Google Puppeteer and Chromium. It integrates easily with Rails views and supports configuration via Puppeteer options and HTML meta tags.

## Use cases
- convert html to pdf in ruby
- generate pdf from rails view template
- take website screenshots as png or jpeg
- render a url to pdf with custom page size
- print html reports to pdf in a ruby app

## When to choose
- you need high-fidelity HTML-to-PDF rendering in a Ruby or Rails application
- you want Chromium-accurate rendering including CSS and JavaScript
- you need both PDF and image (PNG/JPEG) output from HTML

## When to avoid
- you don't want a Node.js/Puppeteer and Chromium dependency
- you need pure-Ruby PDF generation without a headless browser
- you're not working in the Ruby ecosystem

## Facets
- artifact type: library
- maturity: active
- function: pdf, image-processing, http-client
- domain: pdf, web-development, files
- platform: ruby, cross-platform
- tags: puppeteer, chromium, html-to-pdf, screenshots, ruby-gem, rails, nodejs
