The demand for real-time communication tools has skyrocketed during the pandemic. With the rise of remote work, virtual events, and online learning, there is a growing need for reliable, developer-friendly solutions that can deliver seamless audio and video communications. The Huddle01 SDK is a powerful tool designed to meet these requirements, providing a complete set of features for creating interactive, real-time communication applications.

What is Huddle01?

Huddle01 is an innovative DePIN (Decentralized Physical Infrastructure Network) system that fundamentally changes the way we communicate online.
It is the world's first DePIN designed to build decentralized real-time communication (dRTC) infrastructure. Huddle01 provides a secure, private, and cost-effective solution for real-time audio and video communications by routing data streams through a globally distributed network of community-driven nodes.
This decentralized approach significantly reduces data transmission and computation costs while improving the experience through end-to-end encryption and low latency.
The Huddle01 ecosystem includes media nodes that provide bandwidth, coordinators that allocate resources efficiently, and validators that secure the system by validating transactions.
By incentivizing node operators with native $HUDL tokens, Huddle01 is helping develop a thriving community-driven network that provides an excellent alternative to existing centralized communication platforms

What is DePIN?

DePIN stands for Decentralized Physical Infrastructure Network.
A network of physical hardware devices connected in a decentralized manner using blockchain technology.
These devices provide transparent, efficient, and user-centric access to resources. DePIN is supported by a community of node operators who provide computing resources.
In return, they receive rewards in the form of cryptocurrency tokens for their contributions.
This decentralized approach provides a more secure, scalable, and cost-effective infrastructure compared to traditional centralized models.

What is Huddle01 SDK?

Huddle01 SDK is a software development kit (SDK) designed to develop live audio and video applications.
The SDK is built on WebRTC technology, a free and open-source project that allows web browsers and mobile apps to communicate in real time through a simple API.
It provides tools and APIs that developers can use to integrate real-time communication capabilities into their applications.

Key Features and Capabilities

Decentralized Architecture: Huddle01 SDK leverages distributed networks to reduce reliance on centralized servers, significantly reducing costs and improving scalability.
Supported Platforms and Languages: Huddle01 SDK supports a wide range of platforms, including Web (JavaScript), Android, and Windows, making it accessible to developers across various domains.
Low Latency and High-Quality Video: The SDK is optimized for low latency and high video quality, so users can enjoy clear video and audio even in high-traffic environments.
Whiteboarding: The SDK provides whiteboard functionality that allows users to collaborate on ideas and concepts in real-time.

Core Architecture

Understanding the main ideas behind Huddle01's SDK architecture helps make using it easier. You need to know key concepts and terms before using the SDK.

Room: A room in Huddle01 is a virtual meeting space, with a unique roomID. It stays open for multiple meetings, one at a time.
Peer: A peer is someone in a room. It's like an object that holds all their media stuff. Everyone has a unique ID called a peerId; they're all part of a room.
MediaStream: A MediaStream is like a flow of media stuff, like audio or video. It's connected to a specific person in the room.
MediaStreamTrack: This is like one piece of media in a MediaStream, either audio or video.
Local: In a room, your things are called "local." Your Peer Object is localPeer, your Audio Stream is localAudio, and your Video Stream is localVideo.
Remote: Everyone else in the same room is called "remote." Doing things with them needs their ID.
Data Message: Besides media stuff, people in the room can also send short text messages, not more than 280 characters. These are called data messages.
Metadata: Metadata is like extra info you can add to people or the room. The SDKs let you get and set this extra information.
Room States: At any time, a room can be in one of six states which are idle, connecting, connected, failed, left, and closed.

Getting Started with Huddle01 SDK

Get-Started

To get started with the Huddle01 SDK, you have several options depending on your project type:

Web Apps: Integrate the Huddle01 communication tool using JavaScript or React SDK.
Mobile Apps: Use React Native SDK and Flutter for mobile integration.
Server-SDK: The Server SDK creates tokens and securely manages recordings and live streams.

Additionally, Huddle01 also offers a convenient iFrame solution, making it easy to integrate real-time collaboration features directly into your website. With just a few lines of code, developers can embed the Huddle01 web app into their website, allowing users to easily join meetings, share presentations, and collaborate on projects without leaving the website.

The iFrame approach provides a simple way to enable real-time communication capabilities, eliminating the need for extensive user interface customization or development effort. Despite its simplicity, Huddle01 iFrame provides access to Huddle01's full suite of collaboration tools, delivering a rich and engaging user experience.

Developers can customize the appearance of the iFrame to match their website's branding, providing users with a consistent look and feel. Huddle01 provides iFrame integration for both native JavaScript and React frameworks to meet a variety of developer and project needs.

Huddle01 SDK v2 - What's new in it?

The latest version of the Huddle01 SDK(v2.x.x) includes several important updates aimed at improving stability, scalability, and ease of development for creating real-time audio/video communication solutions.
One of the key improvements is global coverage, ensuring optimal connectivity and performance for users around the world. The SDK infrastructure has also been improved and can handle at least 10 times more load than the previous version, providing a smoother user experience even when usage is high.
Through WebSocket integration, reconnection time and WebSocket connection management are optimized, allowing for more smooth response to network outages.
Additionally, the SDK now supports zero-downtime deployments, allowing you to deploy new updates and features without impacting the user experience or causing downtime.
Overall, Huddle01 SDK v2.0 provides a more powerful, scalable, and developer-friendly platform for building real-time communications applications while providing flexibility to adapt to different use cases and requirements.

Cloning a sample application

Copy the demo application built with the Huddle01 SDK using the CLI tool. To get started with the CLI tool, follow these simple steps:
