When serving static files using Ktor, how do you override what content type Ktor sets on the response?

[ribesg]

Looks like you have to reimplement static (more specifically resources as static doesn’t do anything) yourself, and it’s not super easy, not super clean.

@ribesg Could you please log a feature request with your use-cases at https://youtrack.jetbrains.com/newIssue?project=KTOR ?

I’m mostly trying to work around a different problem, which is that Ktor assigns a wrong content type to .map files (like .js.map in my case, or .css.map) and while clients retrieving these files usually don’t care about content type, I wanted to set it as json so that I could see them directly in browser

[ribesg]

I understand that Ktor should respect the “official” list of mime types so I don’t expect that to change, these kind of files having no default/expected content type anyway. But the inability to somehow override the content type kinda surprised me. I tried an interceptor, but you are not allowed to set the value of the Content-Type header which is weird

[hhariri]

Then that’s a different issue. Could you please log the specific problem with the wrong assignment, or tell me what you’d expect these file types to have?

[ribesg]

As I said there is no specific content type associated to these files, my Google skills only got me to application/octet-stream or eventually application/json which is useful for specific debugging but may not make sense. I don’t think the mime types list should be changed but I don’t know what should be done to let users do what they want in this case. I’ll open a general issue
