## What it is
HummusJS is a fast Node.js native module (built on the PDF-Writer C++ library) for creating, parsing, and modifying PDF files and streams. It offers low-level, high-performance PDF manipulation but is no longer officially supported, with MuhammaraJS recommended as a maintained drop-in replacement.

## Use cases
- generate pdf files from node.js
- merge and modify existing pdf documents
- parse pdf file structure programmatically
- append pages to a pdf
- embed images and fonts into pdfs
- manipulate pdf streams at low level

## When to choose
- you need high-performance, low-level PDF creation or modification in Node.js
- you are already using HummusJS or its API
- you are fine maintaining an unsupported library yourself

## When to avoid
- you want a maintained library - use MuhammaraJS instead
- you need high-level PDF rendering or HTML-to-PDF conversion
- you need official support or frequent bug fixes

## Facets
- artifact type: library
- maturity: maintenance
- function: pdf, parser
- domain: pdf, files, developer-tools
- platform: cross-platform
- tags: pdf-generation, pdf-parsing, pdf-manipulation, native-addon, low-level-pdf, nodejs
