cd emsdk
./emsdk install latest
./emsdk activate latest

source emsdk_env.sh

• 3. Build

cmake .. -DCMAKE_TOOLCHAIN_FILE=$EMSDK/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake -DWASM_FEATURE=basic -DENGINE_NCNN_WASM=ON -DENGINE_MNN=OFF -DENGINE_ORT=OFF -DENGINE_NCNN=OFF -DENGINE_TNN=OFF -DENGINE_OPV=OFF -DENGINE_PPLite=OFF
make -j4

cmake .. -DCMAKE_TOOLCHAIN_FILE=$EMSDK/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake -DWASM_FEATURE=simd -DENGINE_NCNN_WASM=ON -DENGINE_MNN=OFF -DENGINE_ORT=OFF -DENGINE_NCNN=OFF -DENGINE_TNN=OFF -DENGINE_OPV=OFF -DENGINE_PPLite=OFF

make -j4

• 4. Deploy

Clone the project, create a folder named aidb in the root project directory and copy the following files into it:

# deploy files
aidb/
├── aidb-wasm-basic.js
├── aidb-wasm-basic.wasm
├── aidb-wasm-simd.js
├── aidb-wasm-simd-threads.js
├── aidb-wasm-simd-threads.wasm
├── aidb-wasm-simd-threads.worker.js
├── aidb-wasm-simd.wasm
├── aidb-wasm-threads.js
├── aidb-wasm-threads.wasm
└── aidb-wasm-threads.worker.js

Run local server:

python3 server.py

• 5. Access local server(chrome as a example)

# launch chrome browser, enter following command to address bar and press ENTER:
