## What it is
A JavaScript base class for building peer-to-peer replicatable data structures using the scuttlebutt gossip protocol. It provides real-time, eventually-consistent replication of state between nodes via duplex streams.

## Use cases
- sync application state between server and clients in real time
- build peer-to-peer replicated data models
- implement collaborative editing features
- gossip-replicate key-value data across nodes
- create eventually consistent distributed data structures

## When to choose
- you need real-time replication of small data models over streams in Node.js
- you want a base class to build CRDT-like replicated data structures
- you are building offline-first or peer-to-peer sync features

## When to avoid
- you need a maintained library with active support
- you need secure or cryptographically verified replication (use Secure Scuttlebutt instead)
- you need large-scale distributed consensus or a production database

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, concurrency, developer-tools
- domain: microservices, developer-tools
- platform: cross-platform
- tags: gossip-protocol, crdt, peer-to-peer, replication, data-sync, real-time, nodejs, javascript
