Similar packages

Other packages similar to graphql-ws

subscriptions-transport-ws

This package is another implementation of GraphQL over WebSocket protocol. It is the predecessor of graphql-ws and was developed by the Apollo team. However, it is now deprecated in favor of graphql-ws, which is more lightweight and has a simpler API.

apollo-server

Apollo Server is a community-driven, open-source GraphQL server that works with many Node.js HTTP server frameworks. Apollo Server supports subscriptions with WebSocket and integrates well with the Apollo ecosystem. It is more feature-rich but also heavier compared to graphql-ws, which is focused solely on WebSocket communication.
