How-to set a response header in the server route
I'd like to know how to explicitly set a header in response to a server route. Specifically, I'd like to set the Content-Type of the returned data.
This question specifically relates to /server routes.
I understand it's possible to set the HTTP response status code using
For example, I have some code that generates a sitemap and returns this as a promise-wrapped buffer. Or some code that generates dynamic images and returns these also as a buffer...
This returns the buffered sitemap text! Great - but there's no content-type set, meaning the browser has to implicitly infer its type. That's fine, but in my use case, a website I supply sitemaps too via a hook neccessitates the content type being explicitly set in the response header. Similarly, another needs those images to have an implicitly-set content-type header to be displayed correctly.
