How it works ? const pubSub = new PubSubClient('ws://localhost:3001', {connect: true,reconnect: true,}) const topicName = 'abc' pubSub.subscribe(topicName, (message) => { console.log(\`Got message from topic ${topicName}\`, message) }) //publish a message to topic pubSub.publish(topicName, {title: 'Hello subscribers in the topic abc', body: 'How are you ?'}) // Broadcast send message to subscribers but not me pubSub.broadcast(topicName, {body: 'this is broadcast message'}) // UnsubscribepubSub.unsubscribe(topicName) Todo@ May limit publisher and time to send message if look like spammer Maybe server need wait a time (short time) if detect mutiple publish messages same to one client and send a batch of messages instead of send a single message. Add Crypto client & server key sharing to decrypt between client & server when connected. More security for WebSocket communication. The message from client to server and server to client is encrypted.
