Lophus

Warning
Still under development and not ready for use.

CI codecov

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

Concept

  • Modular 🔌 - NIPs and high-level interfaces are implemented as optional TypeScript modules, which enables you to keep an app as small as possible.
  • Portable 📦 - The core modules are build upon Web Standard APIs, which makes it possible to run on various environment.
  • Productive 🌊 - Declarative interfaces let you focus on the data flow rather than underlying logic, and strict type checking helps you to avoid runtime errors.
  • Compatible 🤝 - Shares the same data structure for events as nostr-tools.

Documentation
