mapping of accept header to route type

[pke]

Is it possible to map request according to their accept header to svelte routes?

Accept	route
application/xml	routes/index.xml.js
text/xml	routes/index.xml.js
application/vnd.siren+json	routes/index.json.js

IMO you may be better just writing an adapter that will handle the marshalling based on the http header, and use it to decorate the response that the endpoints already return.

You might even be able to add it to the hooks function rather than in each endpoint.

Not sure I understand what you mean (new to svelte + sveltekit). I thought adapters come only into play when building the project like for vercel or node?

Which hooks function you are referring to?

Sorry, I was meaning "adapter" as in classic ports-and-adapters architecture, completely forgetting that Svelte uses the term :) (although a similar concept / reason).

Basically, imagine having a function that you pass the request and response to, that your endpoint has already created as an object. This function could switch on the accept header and apply a different serialization as required.

The hooks function in SK is where you can handle requests (literally, "hook" into the request / response) and add some extra behavior. These are all concepts you'll see in many frameworks and languages under the heading "middleware".
