Description

Hi all ✋

This PR is suppress export ... was not found ... warnings with typescript.

relate: TypeStrong/ts-loader#653

I usually suppress by adding a custom plugin to nuxt.config.ts but, I thought it would be useful to support in the Nuxt.

This is a suggestion. please close if you don't needs this 🙇
Thank you

Hi @Yama-Tomo, thanks for your work !

I'm not really a fan of such plugins suppressing warnings, so ideally I'd prefer an use case where the warnings are not fixable and would showcase the need of this. Could you maybe provide some reproduction where these warnings are persisting in a Nuxt project ?

[Yama-Tomo]

@kevinmarrec Thanks for your comment!

Here is code for my boilerplate for nuxt project.
https://github.com/Yama-Tomo/vue-vuex-typescript-sample

How to reproduction

• 1: checkout the nuxt branch after git clone
  　
• 2.a: comment out the L.59 of extend.webpack.config.ts
• 3.a: execute yarn && yarn dev

or

• 2.b: comment out the L.32-34 of nuxt.config.ts
• 3.b: execute yarn && yarn build

@Yama-Tomo Hm alright, seems to be really specific case.

IMO I don't think that such "suppress warning" feature should be included in Nuxt core, I mean for specific cases it could be useful, but I think it could also suppress warnings that people would still want to be shown.

So even if it would be a togglable feature, I'm kind of against that for now but I would like @pi0 opinion about this stuff :)

PS: That's really a shame that ts-loader still didn't find a fix in almost 2 years

I've discussed further with @atinux on Discord and we decided that's all good :).

Thanks for your great work @Yama-Tomo !
