js-libp2p

js-libp2p is a modular JavaScript implementation of the libp2p networking stack, enabling peer-to-peer applications to discover, connect, and communicate securely without relying on centralized servers. It is designed for developers building decentralized systems, such as IPFS, blockchain nodes, or distributed web apps, who need transport-agnostic, encrypted, and resilient networking. Its interest lies in bringing the core primitives of peer-to-peer networking—like multi-transport support, NAT traversal, and peer routing—directly into the browser and Node.js ecosystems.
