## What it is
A WebSocket client and server library for GraphQL subscriptions, originally the first TypeScript implementation of a WebSocket-based GraphQL subscriptions transport. It is no longer maintained and users are directed to migrate to graphql-ws.

## Use cases
- add real-time graphql subscriptions over websockets
- maintain a legacy nodejs app using subscriptions-transport-ws
- migrate from subscriptions-transport-ws to graphql-ws
- understand the legacy graphql over websocket protocol
- support old clients speaking the subscriptions-transport-ws protocol

## When to choose
- you must maintain or interoperate with an existing system already using this legacy protocol
- you need reference material for migrating to graphql-ws

## When to avoid
- starting any new project - use graphql-ws instead
- you need an actively maintained graphql subscriptions transport
- you want the newer graphql-ws protocol

## Facets
- artifact type: library
- maturity: abandoned
- function: websocket, graphql, http-server
- domain: web-development, apis
- platform: -
- tags: graphql-subscriptions, websocket-transport, deprecated, legacy, real-time, nodejs, typescript
