inferred type of '...' cannot be named without a reference to '...'

I found this in an old question from about a year ago when running into this issue in the process of adding type safety to Waku (new react framework by dai-shi) link to error I plan to use type annotation to unblock this per the recommendation here I wanted to re-ask this though, in case anyone here has come across a better way to fix this issue with a pnpm project over the course of the past year. @ArkDavid is this still something you see from time to time? Edit: Maybe this question is better suited for twitter?

Disregard this ^ I just read to the helpful comment in that ts thread 🤦‍♂️ https://github.com/microsoft/TypeScript/issues/42873#issuecomment-2065572017

Would be interested to know what the specific error you got was

tylerlaws0n•2w ago

It shows in this failed CI job here: https://github.com/dai-shi/waku/actions/runs/10761950734/job/29841704519?pr=854

Error: e2e/fixtures/render-type/src/entries.tsx(6,1): error TS2742: The inferred type of 'default' cannot be named without a reference to '../node_modules/waku/dist/router/common.js'. This is likely not portable. A type annotation is necessary.

Is this related to ArkType or just a general TS question?

tylerlaws0n•2w ago

general ts question... sorry. I kinda just figured this would be a good place to check for an error as weird as this one 😅

ssalbdivad•2w ago

Ahh okay yeah I've dealt with this also so I just wanted to make sure it wasn't something new internally. Generally https://discord.com/channels/957797212103016458/1114601623285678192 is probably a good place to ask broader TS questions, although not a big deal at all. You just had me worried for a sec 😛

tylerlaws0n•2w ago

haha sorry for the scare! definitely good to know that for the future. I appreciate you taking a minute to respond here too 🙂

ssalbdivad•2w ago

No problem! Happy to help Well I didn't really help TBH lol But if I can I will 😛

tylerlaws0n•2w ago

Your old message did! haha I just didn't read it closely enough the first time

ssalbdivad•2w ago

Oh good! I didn't realize you were linking to an old answer of mine haha

tylerlaws0n•2w ago

yep! it was re-assuring to see that as validation that I wasn't mis-configuring something and seems to be a somewhat known issue.

Hi, so how did you fix it in the end? For me I did export * from 'arktype' in that package's type file, but that makes it very slow to build

tylerlaws0n•2w ago

This was the file where the error was occuring. It seems like this will be an internal issue only from what I can tell, so I just added the type annotation as was recommended by that github issue and the error message. It's neat to know that export * could also work, but it definitely does sound slower than I'd like.

tylerlaws0n•2w ago

It seems worth mentioning that this widens the type of router in this case. In other cases I use the inference to collect the types of the paths created from the results of createPage which get returned in a list from createPages: example source code So for this file where I annotated the type of router, I lose that inference and my paths for it have to just revert to any string. In this case that is acceptable, but if this came up after publishing the types to an end user of the library I would need to find a better fix. afaict though, this is just related to pnpm linking within the scope of the monorepo I am developing in, so it shouldn't be in issue after publishing.
