Example:
```
collections:
/podcast/:
permalink: /{slug}/
```
- the name of the collection is remembered as `routerName` (in the case above: "podcast")
- the name of the collection is important for two things
1. context value
2. template name
- the context value is available for specific theme helpers e.g. is helper, body_class helper
- we auto-lookup the collection name in your theme e.g. podcast.hbs
- this logic does not apply to static routes
- if you define templates on your collection, they are stronger than the collection name
no issue
- this mock eat already too much of my/our time
- the idea of adding a knex mock was definitely a failed approach/try
- it's too much to maintaince and have not found a module which does this already
- we have to support any query format
- this is too crazy
- the idea was to use the knex mock for model unit tests, because if we want to unit test models we have to
run through bookshelf, because the whole model layer depends on bookshelf e.g. events
- for now we simply use the real database
- we could use the sqlite3 memory mode, but that would mean every unit test runs on sqlite3
- something to consider for later e.g. run unit tests on one matrix
- run the rest on another matrix for sqlite + mysql

### Dynamic Routing
This is the beta version of dynamic routing.
- we had a initial implementation of "channels" available in the codebase
- we have removed and moved this implementation
- there is now a centralised place for dynamic routing - server/services/routing
- each routing component is represented by a router type e.g. collections, routes, static pages, taxonomies, rss, preview of posts
- keep as much as possible logic of routing helpers, middlewares and controllers
- ensure test coverage
- connect all the things together
- yaml file + validation
- routing + routers
- url service
- sitemaps
- url access
- deeper implementation of yaml validations
- e.g. hard require slashes
- ensure routing hierarchy/order
- e.g. you enable the subscriber app
- you have a custom static page, which lives under the same slug /subscribe
- static pages are stronger than apps
- e.g. the first collection owns the post it has filtered
- a post cannot live in two collections
- ensure apps are still working and hook into the routers layer (or better said: and register in the routing service)
- put as much as possible comments to the code base for better understanding
- ensure a clean debug log
- ensure we can unmount routes
- e.g. you have a collection permalink of /:slug/ represented by {globals.permalink}
- and you change the permalink in the admin to dated permalink
- the express route get's refreshed from /:slug/ to /:year/:month/:day/:slug/
- unmount without server restart, yey
- ensure we are backwards compatible
- e.g. render home.hbs for collection index if collection route is /
- ensure you can access your configured permalink from the settings table with {globals.permalink}
### Render 503 if url service did not finish
- return 503 if the url service has not finished generating the resource urls
### Rewrite sitemaps
- we have rewritten the sitemaps "service", because the url generator does no longer happen on runtime
- we generate all urls on bootstrap
- the sitemaps service will consume created resource and router urls
- these urls will be shown on the xml pages
- we listen on url events
- we listen on router events
- we no longer have to fetch the resources, which is nice
- the urlservice pre-fetches resources and emits their urls
- the urlservice is the only component who knows which urls are valid
- i made some ES6 adaptions
- we keep the caching logic -> only regenerate xml if there is a change
- updated tests
- checked test coverage (100%)
### Re-work usage of Url utility
- replace all usages of `urlService.utils.urlFor` by `urlService.getByResourceId`
- only for resources e.g. post, author, tag
- this is important, because with dynamic routing we no longer create static urls based on the settings permalink on runtime
- adapt url utility
- adapt tests
