* @NOTE
|
|
*
|
|
* We have to figure out the target permalink, otherwise it would be possible to serve a post
|
|
* which lives in two collections.
|
|
*
|
|
* @TODO:
|
|
*
|
|
* This is not optimal and caused by the fact how apps currently work. But apps weren't designed
|
|
* for dynamic routing.
|
|
*
|
|
* I think if the responsible, target router would first take care fetching/determining the post, the
|
|
* request could then be forwarded to this app. Then we don't have to:
|
|
*
|
|
* 1. care about fetching the post
|
|
* 2. care about if the post can be served
|
|
* 3. then this app would act like an extension
|
|
*
|
|
* The challenge is to design different types of apps e.g. extensions of routers, standalone pages etc.
