Build from source and contributing

Please, refer to our Documentation pages: docs.hydralauncher.gg

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.
