socket.io-pubsub-3 v3.1.5

socket.io-pubsub

How to use

const pubsub = require('@google-cloud/pubsub');
const pubsubClient = pubsub();
const io = require('socket.io')(3000);
const pubsubAdapter = require('socket.io-pubsub');
io.adapter(pubsubAdapter(pubsubClient));

By running socket.io with the socket.io-pubsub adapter you can run multiple socket.io instances in different processes or servers that can all broadcast and emit events to and from each other using Google Cloud Pub/Sub.

If you need to emit events to socket.io instances from a non-socket.io process, you should use socket.io-emitter.
