node_modules/@hapi/hapi/lib/types/route.d.ts:2:68 - error TS2307: Cannot find module 'joi' or its corresponding type declarations.

What are you trying to achieve or the steps to reproduce?

create any packet.json and have skipLibCheck = true

What was the result you got?

node_modules/@hapi/hapi/lib/types/route.d.ts:2:68 - error TS2307: Cannot find module 'joi' or its corresponding type declarations.

What result did you expect?

No error

Yeah, the hapi types require the Joi typings to compile. This is not ideal, but how it is currently. I'm sure a PR that decouples it would be very welcome.

You should be able to fix it by installing the joi module as a development dependency.

Are you sure it's not activated by skipLibCheck = false?

If joi is required its not a dev dependency, looking in you packet.json its listed as a dev dependency. adding it to the project using npm install joi removes the error but this is a hack as i see it.

Joi is only required for compiling the typescript types, so it won't be added as a normal dependency. This is similar to the typescript dev dependency.

This is indeed a hack, because there is no decent solution until someone takes the time to decouple it in the hapi typings. Again a PR would be welcome.
