Build

Compile

g++ -std=c++17 main.cpp -o ./main -I ./json/single_include/nlohmann

To build the project, follow these steps:

1. Create a directory for the build:

   mkdir build
   cd build

2. Run CMake to configure the project:

   cmake ..

3. Compile the project:

   make

4. Run the resulting executable:

   ./SimpleHNSW

Compile for Web Assembly using Emscripten

emcc -std=c++17 main.cpp -o ./index.html -I ./json/single_include/nlohmann

To build this project for WebAssembly, follow these steps:

1. Install Emscripten by following the instructions here.

2. Set up the Emscripten environment:

source /path/to/emsdk/emsdk_env.sh

3. Create a directory for the build:

mkdir build-wasm
cd build-wasm

4. Run CMake to configure the project for WebAssembly:

cmake -DEMSCRIPTEN=1 -DCMAKE_TOOLCHAIN_FILE=/path/to/emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake ..

5. Compile the project:

make

The output will be a WebAssembly module along with an HTML file (SimpleHNSW.html) that you can open in a web browser to run the compiled code.

The main.cpp file should remain the same as before, but you may need to adapt it to interact with JavaScript if necessary. For example, you can use emscripten::val to handle JavaScript interactions or create bindings using Emscripten's --bind feature.
