v13.0.0

13.0.0 (2021-11-03)

Breaking Changes

common

• The behavior of the SpyLocation used by the RouterTestingModule has changed to match the behavior of browsers. It no longer emits a 'popstate' event when Location.go is called. In addition, simulateHashChange now triggers both a hashchange and a popstate event. Tests which use location.go and expect the changes to be picked up by the Router should likely change to simulateHashChange instead. Each test is different in what it attempts to assert so there is no single change that works for all tests. Each test using the SpyLocation to simulate browser URL changes should be evaluated on a case-by-case basis.

core

• TypeScript versions older than 4.4.2 are no longer supported.

• NodeJS versions older than v12.20.0 are no longer supported due to the Angular packages using the NodeJS package exports feature with subpath patterns.

• The WrappedValue class can no longer be imported from @angular/core, which may result in compile errors or failures at runtime if outdated libraries are used that are still using WrappedValue. The usage of WrappedValue should be removed as no replacement is available.

forms

• A new type called FormControlStatus has been introduced, which is a union of all possible status strings for form controls. AbstractControl.status has been narrowed from string to FormControlStatus, and statusChanges has been narrowed from Observable<any> to Observable<FormControlStatus>. Most applications should consume the new types seamlessly. Any breakage caused by this change is likely due to one of the following two problems: (1) the app is comparing AbstractControl.status against a string which is not a valid status; or, (2) the app is using statusChanges events as if they were something other than strings.

router

• The default url serializer would previously drop everything after and including a question mark in query parameters. That is, for a navigation to /path?q=hello?&other=123, the query params would be parsed to just {q: 'hello'}. This is incorrect because the URI spec allows for question mark characers in query data. This change will now correctly parse the params for the above example to be {v: 'hello?', other: '123'}.

• Previously null and undefined inputs for routerLink were equaivalent to empty string and there was no way to disable the link's navigation. In addition, the href is changed from a property HostBinding() to an attribute binding (HostBinding('attr.href')). The effect of this change is that DebugElement.properties['href'] will now return the href value returned by the native element which will be the full URL rather than the internal value of the RouterLink href property.

• The router will no longer replace the browser URL when a new navigation cancels an ongoing navigation. This often causes URL flicker and was only in place to support some AngularJS hybrid applications. Hybrid applications which rely on the navigationId being present on initial navigations that were handled by the Angular router should instead
