hey @christian-bromann - do we need to add the .d.cts extension to

core/src/compiler/sys/resolve/resolve-utils.ts

Line 12 in e2965e5

export const isDtsFile = (p: string) => p.endsWith('.d.ts') || p.endsWith('.d.mts');

?

Do we also need to update this line too to cope with these types?

core/src/utils/util.ts

Line 50 in e2965e5

export const isDtsFile = (filePath: string): boolean => {

Then I wonder if we could use one of these utils to replace all the inline checks in the if statements?

@johnjenkins good catch, I reorganised some stuff around, wdyt?

[johnjenkins]

@christian-bromann - just some ideas .. perhaps practically they can't work 'cos the code exists at different times or whatever

[johnjenkins]

presume my micro suggestions aren't workable / not practical? Tiny thing anyway - LGTM 🙂

I wasn't quite sure what you were referring to but you are right, updated the PR.
