[WxtBuilder]: importEntrypoint is causing xxx not defined error.

[nishu-murmu]

Describe the bug

As entrypointLoader is going to be deparecated or has, by default vite-node to import entrypoints as of version 0.19.0

using await wxt.builder.importEntrypoint(entrypointPath) to import options is breaking.

Reproduction

add a file in modules sub-folder of the project
Add this below code

demo.ts

import { addEntrypoint, defineWxtModule } from 'wxt/modules';
import path, { resolve } from 'node:path';

export default defineWxtModule(async (wxt) => {
  const entrypointPath = resolve(
    path.join('src', 'entrypoints'),
    'unlisted.ts',
  );

  console.log({
    entrypointPath,
    dd: await wxt.builder.importEntrypoint(entrypointPath),
  });
  addEntrypoint(wxt, {
    type: 'unlisted-script',
    name: 'demo-module',
    inputPath: entrypointPath,
    outputDir: wxt.config.outDir,
    options: {},
  });
});

Add a unlisted.ts file inside entrypoints sub-folder of the project.

unlisted.ts

export default defineUnlistedScript(() => {
  console.log('injected');
});

Try running

pnpm build

Ahh, yeah, that's a problem... importEntrypoint won't work when called inside the setup function directly... It needs to wait for the config:resolved hook to run before it actually works. It is just incompatible with addEntrypoint :/

Instead, I'd recommend implementing the function yourself and importing the entrypoint inside the hook:

https://github.com/wxt-dev/wxt/blob/main/packages%2Fwxt%2Fsrc%2Fmodules.ts#L56-L58

It's only 3 lines. We should probably deprecate that function for this reason :/ Or update it to automatically import the options if not provided.
