This package contains simple utility functions to use with [React Router](https://reactrouter.com/home).

/**
 * Create a response with only the status 304 and optional headers.
 * This is useful when trying to implement conditional responses based on Etags.

 * export async function loader({ request }: LoaderFunctionArgs) {

 * Create a response with a JavaScript file response.
 * It receives a string with the JavaScript content and set the Content-Type
 * header to `application/javascript; charset=utf-8` always.
 *
 * This is useful to dynamically create a JS file from a Resource Route.
 * @example
 * export async function loader({ request }: LoaderFunctionArgs) {
 *   return javascript("console.log('Hello World')");
 * }
