Webpubsub JavaScript SDK (V4)

This is the official Webpubsub JavaScript SDK repository.

Webpubsub takes care of the infrastructure and APIs needed for the realtime communication layer of your application. Work on your app's logic and let Webpubsub handle sending and receiving data across the world in less than 100ms.

Get keys

You will need the publish and subscribe keys to authenticate your app. Get your keys from the Admin Portal.

Configure Webpubsub

• Integrate the JavaScript SDK into your project:

  • use npm:

    npm install webpubsub
    

  • or download one of our builds from our CDN:
    • https://cdn.webpubsub.com/sdk/javascript/webpubsub.7.0.1.js
    • https://cdn.webpubsub.com/sdk/javascript/webpubsub.7.0.1.min.js

• Configure your keys:

webpubsub = new Webpubsub({
  publishKey : "myPublishKey",
  subscribeKey : "mySubscribeKey",
  uuid: "myUniqueUUID"
})

Add event listeners

webpubsub.addListener({
  message: function (m) {
    // handle messages
  },
  presence: function (p) {
    // handle presence  
  },
  signal: function (s) {
    // handle signals
  },
  objects: (objectEvent) => {
    // handle objects
  },
  messageAction: function (ma) {
    // handle message actions
  },
  file: function (event) {
    // handle files  
  },
  status: function (s) {
  // handle status  
  },
});

Publish/subscribe

var publishPayload = {
    channel : "hello_world",
    message: {
        title: "greeting",
        description: "This is my first message!"
    }
}

webpubsub.publish(publishPayload, function(status, response) {
    console.log(status, response);
})

webpubsub.subscribe({
