NAPI-RS is a minimal library for building pre-compiled NodeJS addons in Rust.

Copy
#[js_function(1)]
fn fibonacci(ctx: CallContext) -> Result<JsNumber> {
  let n = ctx.get::<JsNumber>(0)?.try_into()?;
  ctx.env.create_int64(fibonacci_native(n))
}

Copy
function hello() {
  let result = fibonacci(10000)
  console.log(result)
  return result
}
