## What it is
A Node.js library that parses and serializes Minecraft protocol packets, with support for authentication and encryption. It enables building Minecraft clients, servers, and proxies programmatically.

## Use cases
- create a minecraft bot in node.js
- parse and serialize minecraft packets
- build a custom minecraft server
- implement a minecraft proxy
- authenticate and encrypt minecraft connections
- automate minecraft gameplay programmatically

## When to choose
- you need low-level access to the Minecraft protocol in JavaScript
- you are building bots, clients, servers, or proxies for Minecraft
- you want an actively maintained library with a large ecosystem (PrismarineJS)

## When to avoid
- you need a high-level bot API with ready-made behaviors rather than raw protocol access
- your project is not JavaScript/Node.js based
- you target Minecraft versions outside the library's supported range

## Facets
- artifact type: library
- maturity: active
- function: serialization, auth, networking, proxy, http-client
- domain: gaming-tools, networking, developer-tools
- platform: cross-platform
- tags: minecraft-protocol, packets, minecraft-client, minecraft-server, bot-framework, minecraft, nodejs, javascript
