💁 Possible Solution

🔦 Context

When importing css/font files, parcel automatically injects <link> tags into the react-jsx output. Which I want to customize it for preloading and other use-case, that's why i want to get the bundled css url.

const fontPreloads: LinkDescriptor[] = [
  new URL("npm:@fontsource/inter/400.css", import.meta.url).toString(), // <-- original 
  // new URL("/client/400.c4cd5e01.css", import.meta.url).toString()), // <-- bundled - current behavior
  // "/client/400.c4cd5e01.css", <-- expected behavior
]

💻 Code Sample

"use server-entry";

import { type LinkDescriptor } from "react-router";

const fontPreloads: LinkDescriptor[] = [
  new URL("npm:@fontsource/inter/400.css", import.meta.url).toString(),
].flatMap((href) => {
  return [
    {
      rel: "preload",
      as: "style",
      href,
    },
    { rel: "stylesheet", href },
  ];
});

export const Fonts: React.FC = () => {
  return fontPreloads.map((props, i) => <link key={i} {...props} />);
};
