file-mesh

A decentralized P2P file sharing application built with Go, React, and JavaScript's WebRTC API, enabling direct and end-to-end encrypted data transfer between authenticated client using WebRTC DataChannels.

Introduction

This project was built with the motive to explore decentralized means of sharing data amongst peers, initially on a closed, homogenous network. WebRTC DataChannels enable peer-to-peer communication between devices across network hosting devices and supporting protocols of a large variety. The was coupled with AES-GCM-based end-to-end encryption to provide a safe and private means of sharing data between users, with no intervention from any central party(apart from initially introducing peers to each other).

Features

• Decentralized peer-to-peer communication between authenticated users using WebRTC DataChannels
• End-to-end encryption powered by AES-GCM
• Signalling server between clients powered by WebSockets to exchange SDP messages and ICE candidates
• JWT-based authentication of users with a MongoDB database storing user data
• Seamless transfer of files up to 3 GB in size
• Can handle multiple concurrent file transfers between clients

Getting Started

• Prerequisites

  • Go 1.20+
  • ReactJS
  • JavaScript (WebRTC API)
  • MongoDB
  • Any modern web browser that supports JavaScript's WebRTC API

• Clone the repository

git clone https://github.com/lokeshllkumar/file-mesh.git
cd file-mesh

• Setup the backend server

• Setup the frontend service

• Create a profile with your Email ID and connect with another authenticated user to start sharing!

To-Do

• - Implement a file transfer history page
