It integrates various Web3 features, such as wallet logins, token-gated calls, and decentralized storage using IPFS and Filecoin. This article provides a comprehensive guide to the Huddle01 SDK, diving deep into its functionalities, offerings, and practical applications. Whether you are a beginner or an expert, this guide will help you harness the power of Huddle01 to develop advanced live audio/video applications.

Understanding Huddle01 SDK

Huddle01 SDK is a robust set of tools that allows developers to integrate audio and video communication capabilities into their applications. It supports both Web and mobile platforms, providing SDKs for React, Vanilla JS, Flutter, and React Native. The SDK is designed to offer a seamless development experience with TypeScript support, ensuring type safety and autocompletion for a smoother coding process.

Key Features of Huddle01 SDK

1. Web3 Integration: Huddle01 supports wallet logins, enabling users to authenticate using their crypto wallets. It also allows for token-gated calls and meetings, providing exclusive access based on token ownership.

2. Decentralized Storage: Recordings and data can be stored on IPFS and Filecoin, ensuring data security and decentralization.

3. Real-time Communication: The SDK leverages WebRTC for real-time audio and video communication, ensuring low latency and high-quality interactions.

4. Customizability: Developers can create highly customized applications using Huddle01’s extensive APIs and hooks.

5. Earn Crypto: Users can run Huddle01 nodes to provide resources for Huddle01 services and earn $HUDL tokens in return.

Getting Started with Huddle01 SDK

Prerequisites

Before you start, ensure you have the following:

• Node.js installed

• A package manager like npm or yarn

• A basic understanding of React or Vanilla JS

• Access to Huddle01 API keys (available from the Huddle01 docs)

Installation

To install the Huddle01 SDK, use the following command:

npm install @huddle01/huddle01-client
# or
yarn add @huddle01/huddle01-client

Basic Setup

Here's a basic example of setting up a video call using the Huddle01 SDK in a React application.

1. Initialize the SDK: Import the Huddle01Client and create an instance with your API key.

import { Huddle01Client } from '@huddle01/huddle01-client';

const client = new Huddle01Client({
  apiKey: 'YOUR_API_KEY',
});

1. Join a Room: Use the client instance to join a room.

const roomId = 'your-room-id';
const accessToken = await client.generateAccessToken(roomId, 'host');
await client.joinRoom(roomId, accessToken);

1. Manage Media Streams: Enable and disable audio and video streams as needed.

await client.enableWebcam();
await client.enableMicrophone();

// To disable
await client.disableWebcam();
await client.disableMicrophone();

Advanced Features

Token-Gated Meetings

Token-gated meetings allow you to restrict access based on token ownership. This feature is particularly useful for DAOs or NFT communities.

const roomId = 'token-gated-room-id';
const tokenAddress = 'your-token-address';
const accessToken = await client.generateAccessToken(roomId, 'guest', {
  tokenAddress,
});
await client.joinRoom(roomId, accessToken);

Decentralized Live Streaming

Huddle01 supports decentralized live streaming using Livepeer. You can stream live video content to a decentralized network.

await client.startLiveStreaming({
  service: 'livepeer',
  streamKey: 'your-stream-key',
});

Building Applications with Huddle01

Example Project: Collaborative Whiteboard

A collaborative whiteboard is an excellent project to showcase the capabilities of the Huddle01 SDK. Here's a step-by-step guide to building one.

1. Set Up the Project: Initialize a new React project and install the necessary dependencies.

npx create-react-app collaborative-whiteboard
cd collaborative-whiteboard
yarn add @huddle01/huddle01-client yjs websockets

1. Initialize Huddle01 SDK: Set up the Huddle01 client as described earlier.

2. Integrate Yjs for Real-time Collaboration: Yjs is a CRDT implementation that allows real-time collaboration.

import * as Y from 'yjs';
import { WebsocketProvider } from 'y-websocket';
import { Huddle01Client } from '@huddle01/huddle01-client';

const ydoc = new Y.Doc();
const provider = new WebsocketProvider('wss://demos.yjs.dev', 'room-id', ydoc);

const client = new Huddle01Client({
  apiKey: 'YOUR_API_KEY',
});

1. Create the Whiteboard Component: Use a drawing library like react-sketch to create the whiteboard.

import React, { useEffect, useRef } from 'react';
import Sketch from 'react-sketch';

const Whiteboard = () => {
  const sketchRef = useRef();

  useEffect(() => {
    // Synchronize the whiteboard state with Yjs
    const sketchDoc = ydoc.getMap('sketch');
    sketchDoc.observe(event => {
      sketchRef.current.loadPaths(event.target.toJSON());
    });
  }, []);

  const onChange = () => {
    const paths = sketchRef.current.toJSON();
    ydoc.getMap('sketch').set('paths', paths);
  };

  return (
    <Sketch
      ref={sketchRef}
      onChange={onChange}
    />
  );
};

export default Whiteboard;

1. Implement Video and Audio: Add video and audio streams using the Huddle01 SDK.

import { useEffect } from 'react';

const VideoCall = ({ client }) => {
  useEffect(() => {
    const setupMedia = async () => {
      await client.enableWebcam();
      await client.enableMicrophone();
    };

    setupMedia();

    return () => {
      client.disableWebcam();
      client.disableMicrophone();
    };
  }, [client]);

  return (
    <div>
      <video id="local-video" autoPlay muted />
      <video id="remote-video" autoPlay />
    </div>
  );
};

export default VideoCall;

1. Combine Everything in the App Component:

import React, { useEffect, useState } from 'react';
import { Huddle01Client } from '@huddle01/huddle01-client';
import Whiteboard from './Whiteboard';
import VideoCall from './VideoCall';

const App = () => {
  const [client, setClient] = useState(null);

  useEffect(() => {
    const initClient = async () => {
      const huddleClient = new Huddle01Client({
        apiKey: 'YOUR_API_KEY',
      });
      await huddleClient.joinRoom('your-room-id', 'your-access-token');
      setClient(huddleClient);
    };

    initClient();
  }, []);

  return (
    <div className="App">
      {client && (
        <>
          <VideoCall client={client} />
          <Whiteboard />
        </>
      )}
    </div>
  );
};

export default App;

Why Huddle01?

Developing with the Huddle01 SDK can be a new case for DePIN projects.

Benefits:

1. Network Latency: Ensuring low latency can be challenging, especially for users in remote areas. Huddle01's decentralized protocol helps mitigate this by allowing local node hosting.
