Lophus

:construction: Still under development and not ready for use.

Lophus is an experimental TypeScript library for development of Nostr clients and relays, oriented to web standards and edge environments.

Features

• Modular 🔌 - NIPs and high-level interfaces are implemented as optional TypeScript modules, which makes your apps as small as possible.
• Fast ⚡ - Carefully designed to be performant. Fully asynchronous and non-blocking. Use native code of a runtime via Web APIs.
• Portable 📦 - No runtime-specific code or external dependencies in the core modules so that it can work on various platforms.
• Type-safe 🛡️ - Thoroughly typed with insanity.
• Compatible 🤝 - Shares the same data structure for events as nostr-tools.

Project Structure

@lophus/nips

Provides a set of modules that implement the Nostr protocol and its extensions. Supposed to be the entry point for most developers who want to use Lophus.

@lophus/std

Provides high-level interfaces and utilities, and functionalities that depends on third-party libraries.

@lophus/core

Contains the core modules that implement the basic architecture of Lophus. Used for implementation of NIPs, or possibly your own Nostr-like protocols.

@lophus/lib

General-purpose modules that are developed for Lophus, but not directly related to the Nostr protocol. You may use them in any TypeScript project.

@lophus/app

A SSR-oriented Nostr client application that demonstrates how to use the library.

@lophus/bench

Performance tests for Lophus and other Nostr libraries. Highly experimental.
