Guide: Listening to Poll Updates with pollz-js SDK

Prerequisites

Before you proceed with listening to poll updates using the pollz-js SDK, ensure that you have already initialized the SDK and created a poll by following the relevant guides in the "Guides" section.

Listen to Poll Updates

Stay informed about real-time changes in a specific poll by setting up a listener using the pollz-js SDK.

Step 1: Import the SDK

In your Node.js application, ensure you have already imported the pollz-js SDK:

const { PollzSDK } = require('pollz-js');

Step 2: Listen to Updates

Use the listen method provided by the polls module of the SDK to set up a listener for a specific poll. Provide the poll ID and a callback function to handle the updates.

const pollz = new PollzSDK();

// Replace 'your-app-id' and 'your-app-secret' with actual credentials
const initInput = {
  appId: 'your-app-id',
  appSecret: 'your-app-secret',
};

// Initialize the SDK
await pollz.init(initInput);

// Replace with the actual poll ID
const pollIdToListen = 1;

// Define a callback function to handle updates
const handlePollUpdate = (updatedPoll) => {
  console.log('Poll Updated:', updatedPoll);
};

// Set up the listener
const unsubscribe = pollz.polls.listen(pollIdToListen, handlePollUpdate);

// To stop listening, call the unsubscribe function
// unsubscribe();

Replace 'your-app-id' and 'your-app-secret' with the actual credentials obtained from the Pollz platform. Adjust the pollIdToListen according to the poll you want to receive updates for.

Congratulations! You have successfully set up a listener to receive real-time updates for a specific poll using the pollz-js SDK.
