Servo lightweight performance for embedding web technologies in applications

Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64-bit macOS, 64-bit Linux, 64-bit Windows, 64-bit OpenHarmony, and Android.

Servo welcomes contribution from everyone. Check out:

• The Servo Book for documentation
• servo.org for news and guides

Coordination of Servo development happens:

• Here in the Github Issues
• On the Servo Zulip
• In video calls advertised in the Servo Project repo.

For more detailed build instructions, see the Servo book under Setting up your environment, Building Servo, Building for Android and Building for OpenHarmony.

• Download and install Xcode and brew.
• Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh
• Install rustup: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
• Restart your shell to make sure cargo is available
• Install the other dependencies: ./mach bootstrap
• Build servoshell: ./mach build

• Install curl:
  • Arch: sudo pacman -S --needed curl
  • Debian, Ubuntu: sudo apt install curl
  • Fedora: sudo dnf install curl
  • Gentoo: sudo emerge net-misc/curl
• Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh
• Install rustup: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
• Restart your shell to make sure cargo is available
• Install the other dependencies: ./mach bootstrap
• Build servoshell: ./mach build

• Download uv, choco, and rustup
  • Be sure to select Quick install via the Visual Studio Community installer
• In the Visual Studio Installer, ensure the following components are installed:
  • Windows 10 SDK (10.0.19041.0) (Microsoft.VisualStudio.Component.Windows10SDK.19041)
  • MSVC v143 - VS 2022 C++ x64/x86 build tools (Latest) (Microsoft.VisualStudio.Component.VC.Tools.x86.x64)
  • C++ ATL for latest v143 build tools (x86 & x64) (Microsoft.VisualStudio.Component.VC.ATL)
  • C++ MFC for latest v143 build tools (x86 & x64) (Microsoft.VisualStudio.Component.VC.ATLMFC)
• Restart your shell to make sure cargo is available
• Install the other dependencies: .\mach bootstrap
• Build servoshell: .\mach build

• Ensure that the following environment variables are set:
  • ANDROID_SDK_ROOT
  • ANDROID_NDK_ROOT: $ANDROID_SDK_ROOT/ndk/26.2.11394342/ ANDROID_SDK_ROOT can be any directory (such as ~/android-sdk). All of the Android build dependencies will be installed there.
• Install the latest version of the Android command-line tools to $ANDROID_SDK_ROOT/cmdline-tools/latest.
• Run the following command to install the necessary components:
  sudo $ANDROID_SDK_ROOT/cmdline-tools/latest/bin/sdkmanager --install \ "build-tools;34.0.0" \ "emulator" \ "ndk;26.2.11394342" \ "platform-tools" \ "platforms;android-33" \ "system-images;android-33;google_apis;x86_64"
• Follow the instructions above for the platform you are building on

• Follow the instructions above for the platform you are building on to prepare the environment.
• Depending on the target distribution (e.g. HarmonyOS NEXT vs pure OpenHarmony) the build configuration will differ slightly.
• Ensure that the following environment variables are set
  • DEVECO_SDK_HOME (Required when targeting HarmonyOS NEXT)
  • OHOS_BASE_SDK_HOME (Required when targeting OpenHarmony)
  • OHOS_SDK_NATIVE (e.g. ${DEVECO_SDK_HOME}/default/openharmony/native or ${OHOS_BASE_SDK_HOME}/${API_VERSION}/native)
  • SERVO_OHOS_SIGNING_CONFIG: Path to json file containing a valid signing configuration for the demo app.
• Review the detailed instructions at Building for OpenHarmony.
• The target distribution can be modified by passing --flavor=<default|harmonyos> to `mach <build|package|install>.
