Hub npm package

The public package @hazer-bjtu/simplex-hub includes the Hub server, configuration templates, compiled browser panel, and user documentation. It requires Node.js 22.18 or newer. No separate panel build is needed.

npm install -g @hazer-bjtu/simplex-hub
simplex-hub --help

The C++ worker is installed separately. Use simplex-hub install-worker with an explicit platform, or download a worker archive from GitHub Releases. See Installation for platform requirements, worker installation, and starting the Hub.

UI SDK

The package exposes the contract-only ESM entry point @hazer-bjtu/simplex-hub/ui, including TypeScript declarations. It provides public types and protocol constants for independent clients; it does not provide a transport, state store, or server API. Importing it does not load the Hub server or its runtime dependencies, and browser consumers need no Node polyfills.

The SDK shares the Hub package version. Compatibility with a running Hub is established through protocol metadata and advertised capabilities, not by assuming that matching npm versions imply matching remote capabilities. See the UI SDK guide for the contract, client responsibilities, and terminal/Web examples.

Release publishing is maintained by the repository owner. Maintainers can find the release and recovery runbook in the repository's contribution guide.
