ruff_fmt's Issues

Support for dynamic importing?

I am using vite in react.js and in my async function I am trying to dynamically import the package.

async function formatCode(code) {
    const init = await import("@wasm-fmt/ruff_fmt/vite");
    const { format } = await import("@wasm-fmt/ruff_fmt/vite");
    await init();
    return await format(code);
}
