Entry file exports not included in the AMD output

[fif154]

Hi!

I am using Vite with TypeScript and trying to use Rollup to generate AMD output. In my main.tsx, which is the entry point for the app, I have one function: export const init () => { ... }. Unfortunately, this function is not part of the generated AMD output when building app. Here is my Vite + Rollup config:

{
  plugins: [react()],
  build: {
    outDir: "./amd/build",
    preserveEntrySignatures: "strict",
    rollupOptions: {
      input: "./src/main.tsx",
      output: {
        format: "amd",
        entryFileNames: "app-lazy.min.js",
        exports: 'named',
      },
    },
  },
}

and here is the function defined in main.tsx

export const init = () => {
    ReactDOM.createRoot(document.getElementById("root")!).render(
        <App />
    );
}

I would appreciate any help, thanks!

I have just found out that I have misplaced preserveEntrySignatures option into vite configuration. After moving it into rollup config it is working as expected.
Fixed config:

{
  plugins: [react()],
  build: {
    outDir: "./amd/build",
    rollupOptions: {
      preserveEntrySignatures: "strict",
      input: "./src/main.tsx",
      output: {
        format: "amd",
        entryFileNames: "app-lazy.min.js",
        exports: 'named',
      },
    },
  },
}
