Why can't resource routes loaders and actions return raw responses like regular routes?

[jmjpro]

Regular routes can just return json like this return {a: 1} whereas in a resource route it needs to be Response.json({a: 1}). The docs at https://reactrouter.com/how-to/resource-routes don't explain why there's a difference? Can we add some elaboration on this topic?

Because return { a: 1 } is not a response, is a JS object, you need to return a Response, the Response.json helps you create a new Response instance.

For non-resource routes if your loaders/actions returns a plain JS object then RR is passing that to the data response helper.

With the latest release a PR was released that loosen this restriction allowing you to send raw JS objects, and it will pass it to Response.json or return it as plain/text.

Glad to hear that resource routes and non-resource routes are moving toward parity!
