servo v0.3.0

Trying out the Servo Tech Demo

Linux

If you see an error loading shared libraries when starting servo on Linux, please refer to the troubleshooting guide.

HarmonyOS

Please note that the servo-aarch64-linux-ohos.hap attached here is signed for OpenHarmony, not HarmonyOS. For HarmonyOS self-signing is currently required - You can download the servo-aarch64-linux-ohos.so shared library and use DevEco Studio to follow the instructions in the ArkTS Servo Demo repository
