This is fork of µWS project, with modifications to support node, node-gyp, node-pre-gyp and cross compile with Android NDK for Android device.

Cross-compile for Android

Prerequisite

Cross-compiling nodejs, and node modules (should have support to node-pre-gyp) requires standalone Android NDK to be installed firstly. Android NDK can be downloaded at Android developer or China Android developer website for chinese mainland user.

Android NDK provides a script, at build/tools/make-standalong-toolchain.sh, that can be used with to generate the standalone toolchain. Below is an example used for standalone toolchain generation for Android Jellybean device.

# /path/to/android-ndk/build/tools/make-standalone-toolchain.sh \
    --toolchain=arm-linux-androideabi-4.6 \
    --arch=arm \
    --install-dir=/path/to/standalone/toolchain \
    --platform=android-17

Change --toolchain & --platform options to fit your Android version.

Cross-toolchain setup

# export CC=/path/to/standalone/toolchain/bin/arm-linux-androideabi-gcc
# export AR=/path/to/standalone/toolchain/bin/arm-linux-androideabi-ar
# export CXX=/path/to/standalone/toolchain/bin/arm-linux-androideabi-g++
# export LINK=/path/to/standalone/toolchain/bin/arm-linux-androideabi-g++

The node-gyp will use these settings to compile and link the target.

Install dependency packages

Just simply do npm install in uWebSockets to install the dependency packages. node-pre-gyp is needed for the cross compiling.

Configure

# ./node_modules/node-pre-gyp/bin/node-pre-gyp --target_arch=arm --target_platform=android --target=6.10.3 --nodedir=/path/to/6.10.3/nodejs configure

Note that --target and --nodedir are only needed if compile for a specific nodejs version used on the device.

build

# ./node_modules/node-pre-gyp/bin/node-pre-gyp build

When build completed, the generated binary can be found at ./lib/binding/node-v48-android-arm/node_uws.node
