This is better since it will allow to convert URLs to snapshot and use
metadata without the need for Observables

@jasonaden I can close this, since as you can see in my other PR #30411 , even if recognize is synchronous it can't be used to retrieve a Snapshot without the use of follow redirect that is async.

atscott

Hi @yelhouti, can you rebase this PR? I'm generally in favor of removing the Observable nature from recognize since it's not necessary.

packages/router/src/recognize.ts

-      this.inheritParamsAndData(routeState._root);
-      return of (routeState);
-
-    } catch (e) {


Should this try...catch be moved to operators/recognize.ts to avoid unintentionally throwing errors that can't be handled by catchError?

You also removed the test for the error case below. Maybe add that back and use the recognize operator.

…th parents There are two parts to this commit: 1. Revert the changes from angular#38379. This change had an incomplete view of how things worked and also diverged the implementations of `applyRedirects` and `recognize` even more. 2. Apply the fixes from the `recognize` algorithm to ensure that named outlets with empty path parents can be matched. This change also passes all the tests that were added in angular#38379 with the added benefit of being a more complete fix that stays in-line with the `recognize` algorithm. This was made possible by using the same approach for `split` by always creating segments for empty path matches (previously, this was only done in `applyRedirects` if there was a `redirectTo` value). At the end of the expansions, we need to squash all empty segments so that serializing the final `UrlTree` returns the same result as before. Fixes angular#39952 Fixes angular#10726 Closes angular#30410
