Using Concrete-core from Javascript

This crate exposes an experimental Javascript interface to the concrete-core library. Using this API, it is possible to execute FHE operations in the browser, for instance.

Building concrete-core-wasm for nodejs

To build concrete-core-wasm, you will not only need Rust to be installed, but also a named wasm-pack. This tool will not only call the rust compiler to generate the wasm code, but will also generate a Javascript boilerplate to ease the integration with your use case (be it nodejs or for the browser).
To install wasm-pack see the project homepage.
Then you can use wasm-pack to compile the concrete-core-wasm API with:
wasm-pack build --target nodejs
