Get the pattern for the current route

[rightaway]

If I do ctx.url I can get the actual URL like /users/123/456, but I'd like to suggest a feature where we can get the router pattern that was matched like /users/:idA/:idB for the current route. Something like ctx.router.pattern.

you can get the matched route by using: ctx._matchedRoute

@DY6229 do you know how to get the matched route when using nested routers? In that case the info dissapears

[DinaYakovlev]

@ChrisLahaye Yes I encountered the same issue. couldn't find any simple solution to this, except for getting the route by-myself using the router.match() function.
for example lets say you have the url: /pets/{pet_id}/test
you can see that ctx._matchedRoute will look something like this: /pets/{pet_id}(.*)
the /pets/{pet_id} is your main route, so you can conclude that /test will be the sub route.
using router.match('/test', method) you can get all possible routes and from there to build your own matched route.
You can look at my full implementation here:

@DinaYakovlev thank you for your reply. I just stopped using nested routes and attached multiple routers to my webserver.
