You should probably remove @types/express from package.json too? It's not used anywhere anymore.

[kevinmarrec]

@trygveaa You're right, it is also a dependency of @types/compression : https://github.com/nuxt/typescript/blob/master/yarn.lock#L2176 so it can be safely removed from package.json

@kevinmarrec: Why does it matter if it's a dependency of @types/compression when it isn't used?

[kevinmarrec]

@trygveaa I meant even if it was used it could have been omitted from package.json as @types/compression would install it anyways :)

I've local changes ready but there's an issue regarding a package (zloirock/core-js#711) which is buggy until NPM registry is correctly updated, so i'm just waiting a bit to have the lock file maintnance as well to have yarn.lock clean after removal.
