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. Part 1: WebSocket Client and WebSocket Server Part 2: Subscription : Publish, Subscribe, Broadcast Part 3: Implement auto reconnect Part 4: Handle Unsubscribe Demo Github: https://github.com/tabvn/pubsub Video Playlist here

Create your own PubSub Client & Server use WebSocket
