## Build from source and contributing

Please, refer to our Documentation pages: [docs.hydralauncher.gg](https://docs.hydralauncher.gg/getting-started)

### Local development requirements

- Node.js + Yarn
- Rust toolchain (for `hydra-native`)
- Git and a C++ toolchain (Visual Studio C++ Build Tools on Windows, GCC/Clang on Linux, Xcode command-line tools on macOS). The native build obtains CMake and CTest automatically through vcpkg.

After installing dependencies, `postinstall` now builds the Rust native addon automatically (`hydra-native/hydra-native.node`).

The native build includes a Rust wrapper around pinned libtorrent. Development and packaged torrenting no longer require Python.

On Windows x64 and Linux x64, the libtorrent bridge comes prebuilt from `native/torrent-bridge/prebuilt`, so installs skip compiling libtorrent through vcpkg. Other platforms build it from source. When a branch push changes `native/torrent-bridge` or `scripts/build-torrent-bridge.cjs`, the "Torrent bridge prebuilts" workflow rebuilds the binaries and commits them to that branch; until then, installs build the bridge from source. Set `HYDRA_TORRENT_BRIDGE_FROM_SOURCE=1` to always build it from source.
