Question about socket.io

[paul-bell]

Hello,

Your npmjs.com page shows Web Socket servers realized via:

• ws
• uWebSockets.js
• fastify-websocket

Instead of these, can I use socket.io together with graphql-ws?

Thank you.

graphql-ws and it's accompanying GraphQL over WebSocket Protocol is purely for WebSockets. Since Socket.io leverages more than just WebSockets (HTTP long-polling), graphql-ws will not be supporting it.

Still, you should be able to implement the server on top of Socket.io using makeServer (see "Server usage with ws" recipe for a quick start). However, you'll have to implement the client from scratch completely on your own.

Hey, saw this issue and wanted to share that a while back I built a GraphQL over Socket.io transport:

• https://github.com/n1ru4l/graphql-live-query/tree/main/packages/socket-io-graphql-server
• https://github.com/n1ru4l/graphql-live-query/tree/main/packages/socket-io-graphql-client

Disclaimer that it does not follow the GraphQL over WebSocket Protocol at all. It basically only glues together the graphql-js functionality with Socket.io. I never used it in a large-scale deployment and only for an app that you host for ~15 concurrent users.
