refs #9601 ### 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
