Describe the Bug

In some ES module packages, the exports field in package.json only includes one import field. This causes some resolution errors when imported to server components. However, getStaticProps and other data-fetching functions in pages directory still works fine.

Since it's quite vague to me, I think I will continue with the example. Clone the repo linked below.

The path /test (in pages directory, with getStaticProps) works as intended. Meanwhile, / (RSC in app directory) doesn't, with a confusing error message:

Module not found: Package path . is not exported from package /path/to/node_modules/periscopic
(see exports field in /path/to/node_modules/periscopic/package.json)

That is (apparently) because periscopic's exports field is like this

"exports": {
  "import": "./src/index.js"
}

After modifying this exports manually, in periscopic and 2 other similar modules (is-reference and estree-walker),

- "exports": {
-  "import": "./src/index.js"
- },
+ "exports": "./src/index.js",

then / works as intended.

Ref: https://github.com/orgs/mdx-js/discussions/2168

Expected Behavior

/ should not crash and gives the same output as /test in the linked reproduction repository.

To Reproduce

Mentioned in the "Describe the Bug" section.

Clone the repository
npm install
npm run dev
Open /: crash
Open /test: works normally

The text was updated successfully, but these errors were encountered:

Fixes #42534 * Use eager `import()` to load page/layout to avoid esm module resolution error, eager is to make sure all the sub resources like css are also included * Fix layer detection, should use `module.layer` directly since `module.resourceResolveData` is not alway presented. It lost when switching from `require()` to `import()` for page/layout component ## Bug - [x] Related issues linked using `fixes #number` - [x] Integration tests added - [ ] Errors have a helpful link attached, see `contributing.md`

Hi can you try again with [email protected]? We patched a fix into it 🙏

joulev · 2022-11-10T12:56:51Z

@huozhi Hi, unfortunately it doesn't work for v13.0.3-canary.3 yet :( in the repro repo above I have upgraded to canary.3 as well and it didn't work.

huozhi · 2022-11-10T13:37:59Z

Gotcha seems related to another issue, reopened

) Should be able to resolve `exports.import` condition for esm packages only when import them in server components Fixes: #42534 ## Bug - [x] Related issues linked using `fixes #number` - [x] Integration tests added - [ ] Errors have a helpful link attached, see `contributing.md`

joulev · 2022-11-11T04:44:58Z

It has been fixed now, thanks! 🚀

huozhi · 2022-11-11T14:49:54Z

@schickling Can you try [email protected] to see if it works for you with the issue you mentioned in #41865 (comment)? I tried your reproduction it seems resolved the issue for me

schickling · 2022-11-11T14:50:30Z

Works 🙌

I had a similar issue with [email protected] & [email protected]. It would not fin react-dom/server.js on the server side (API route).
Upgrading to [email protected] resolved the issue for me.
