`import.meta.glob` expansion cannot be observed from user land plugin since 7.1.2

[hi-ogawa]

Describe the bug

• main.js

console.log(import.meta.glob('./repro.js'));

• vite.config

    {
      name: 'debug',
      enforce: 'post',
      transform: {
        order: 'post',
        handler(code, id) {
          if (id.includes('/main.js')) {
            console.log('[transform:post]', { id, code });
          }
        },
      },
    },

• log on 7.1.1

$ vite build
...
[transform:post] {
  id: '/home/projects/vitejs-rolldown-vite-mtmswjfm/src/main.js',
  code: 'import { __vitePreload } from "\x00vite/preload-helper.js";console.log(/* #__PURE__ */ Object.assign({"./repro.js": () => __vitePreload(() => import("./repro.js"),__VITE_IS_MODERN__?__VITE_PRELOAD__:void 0)}));\n' +
    '\n' +
    "document.querySelector('#app').innerHTML = `hello`;\n"
}

• log on 7.1.2

$ vite build
...
[transform:post] {
  id: '/home/projects/vitejs-rolldown-vite-mtmswjfm/src/main.js',
  code: "console.log(import.meta.glob('./repro.js'));\n" +
    '\n' +
    "document.querySelector('#app').innerHTML = `\n" +
    '  <div>\n' +
    '    <h1>Hello Vite!</h1>\n' +
    '  </div>\n' +
    '`;\n'
}

---

My use case is to use "post" transform to strip away all the code but import so that it can traverse the entire module graph faster during rsc scan build.

To be honest, I think I should fix this on rsc plugin side by keeping import.meta.glob during scan build, but if anyone has an idea, it's very welcome. Also I'm not sure if other plugins in the wild rely on the previous behavior.

---

In the long run, rsc scan should be somehow reworked to not require extra dedicated build and that's partly the reason I don't mind adding a workaround on my end.

This might be because we enabled native plugins by default in version 7.1.2, and the native import-glob plugin runs via the transform_ast hook, which is a built-in hook in Rolldown. Since transform_ast always runs later than transform, its execution happens afterward.

[hi-ogawa]

My use case specifically is a bit weird one (and I have a workaround so not blocking vitejs/vite-plugin-react#721), but I think it was a nice property that user land post transform can observe all imports simply by es-module-lexer. It's possible that new behavior might confuse some other plugins.

Since import.meta.glob shouldn't appear many times in the whole build, isn't it possible to change builtin implementation to use "regex code filter + extra parse/codegen" inside rust transform hook without performance hit?

Not sure if it's the same issue, but this import is ignored with rolldown-vite: import.meta.glob(['../assets/**', '../svgsprite/**/*.svg', '../icons/**/*.svg']), assets are missing in the manifest.json (using https://github.com/laravel/vite-plugin)

[hi-ogawa]

@Razunter Can you provide a reproduction?

[rayriffy]

I do have small repro here, I’m trying to debug import glob issue with native modules as well. Details and what I found already in README. but in which I think might related to #365

[hi-ogawa]

generouted has this pattern https://github.com/oedotme/generouted/blob/ec147f5d21f2b249b14697f8f308bed23a045932/packages/react-router/src/plugin/options.ts#L8. Indeed, this looks like glob compatibility issue #365.

@Razunter Can you provide a reproduction?

Can't reproduce on a small project and can't publish the large one...
import.meta.glob(['../assets/**', '../svgsprite/**/*.svg', '../icons/**/*.svg']) fails, but wrapping it in console.log makes it work (in a broken way):

console.log(import.meta.glob(['../assets/**', '../svgsprite/**/*.svg', '../icons/**/*.svg']))

But *.svg gets transformed to *.js:

"resources/sparkles/assets/logo-main.svg":{"file":"assets/logo-main-Di3hRtZh.js","name":"logo-main","src":"resources/sparkles/assets/logo-main.svg","isDynamicEntry":true,"assets":["assets/logo-main-8Z7lqjxw.svg"]}

Previous manifest entry was

  "resources/sparkles/assets/logo-main.svg": {
    "file": "assets/logo-main-8Z7lqjxw.svg",
    "src": "resources/sparkles/assets/logo-main.svg"
  },

TLDR: something weird, but probably unrelated to this issue.

I have a sveltekit project, and since updating a few packages my images no longer load, managed to narrow it down to this issue.

Versions 7.1.1 and below work correctly, but 7.1.2 and above all fail to load my images.

Relevant import.meta.glob call, i have tried multiple variations including removing everything except eager true, they all return an empty object.

    const sourcesDesktop = import.meta.glob(`$lib/assets/img/bg/Desktop-*`, {
        eager: true,
        query: { enhanced: true, w: '3840;3440;3072;2560;2208;1920;1536', format: 'webp;avif;jpg' },
        import: "default"
    });

Relevant packages:

    "vite": "npm:rolldown-vite@7.1.5",
    "svelte": "5.38.6",
    "svelte-check": "4.3.1",
    "@sveltejs/adapter-node": "5.3.1",
    "@sveltejs/enhanced-img": "0.8.1",
    "@sveltejs/kit": "2.36.3",
    "@sveltejs/vite-plugin-svelte": "6.1.3",

Is there anything i can do on my end to help troubleshoot this?

[shulaoda]

@timotejroiko You could try rolldown-vite@7.1.5 or set enableNativePlugins to false.
