## What it is
Ringpop-node is a Node.js library that provides application-layer sharding via a consistent hash ring built on top of a SWIM-style membership protocol, with request forwarding for routing. It coordinates distributed Node.js applications so they scale and tolerate node failures. The project is no longer under active development.

## Use cases
- shard a nodejs application across a cluster
- build a fault-tolerant distributed hash ring
- coordinate membership among distributed nodes
- forward requests to the node responsible for a key
- scale out stateful services horizontally

## When to choose
- you maintain a legacy Node.js stack already using TChannel and ringpop
- you need a proven consistent-hashing plus membership library for an older Node 0.10 environment

## When to avoid
- starting a new project, since it is no longer actively developed
- you need modern Node.js version support
- you want a maintained sharding or membership solution with community support

## Facets
- artifact type: library
- maturity: abandoned
- function: middleware, routing, concurrency
- domain: microservices, backend, developer-tools
- platform: -
- tags: consistent-hashing, sharding, membership-protocol, swim, tchannel, distributed-coordination, nodejs
