@mlc-ai/web-xgrammar v0.1.0

web-xgrammar

This folder contains the source code and emcc bindings for compiling XGrammar to Javascript/Typescript via emscripten.

Build from source

1. Install emscripten. It is an LLVM-based compiler that compiles C/C++ source code to WebAssembly.

   • Follow the installation instruction to install the latest emsdk.
   • Source emsdk_env.sh by source /path/to/emsdk_env.sh, so that emcc is reachable from PATH and the command emcc works.
   • We can verify the successful installation by trying out emcc in the terminal.

2. Modify the content of cmake/config.cmake to be web/config.cmake.

3. Run the following

   source /path/to/emsdk_env.sh
   npm install
   npm run build

Example

To try out the test webpage, run the following

cd example
npm install
npm start

Testing

For testing in node environment, run:

npm test
