Angular v15.1 deprecated the `CanLoad` guard in favor of `CanMatch`.
This commit removes the support for `CanLoad` when generating a guard with the CLI, to encourage developers to use `CanMatch` instead.
BREAKING CHANGE:
The CLI no longer allows to generate `CanLoad` guards. Use `CanMatch` instead.
Functional guards and resolvers were introduced in the Angular router in v14.2.
This commit adds the ability to generate functional router guards by
specifying `--guardType` instead of `--implements`. These guards are also
accompanied by a test that includes a helper function for executing the
guard in the `TestBed` environment so that any `inject` calls in the
guard will work properly. Functional resolvers are generated by adding
the `--functional` flag.
The `CanMatch` guard was added in v14.1 but not added
to the list of possible interfaces to implement.
This commit adds `CanMatch` to the list of possible
interfaces to implement. It has the same type imports
as the CanLoad interface.
An internal schematics helper rule has been introduced for Angular schematics that only generate a set of project files from a set of templated files. Multiple current generation schematics contained essentially the same code which increased the sustainment burden and made refactoring and improvements more complicated.
Currently, if the user hits `<Enter>` before selecting an interface to implement, the CLI generates a broken guard that implements no interface. With this commit, the CLI forces a choice in interactive mode and generates a `CanActivate` guard by default.
Currently when using `ivy-ngcc` it will print out a warning
```
Failed to read entry point info from //node_modules/@schematics/angular/workspace/files/package.json with error SyntaxError: Unexpected token < in JSON at position 1121.
```
Fixes#13378
This aligns options that do the same thing:
1) `skipSpecs` and `spec` has been deprecated in favor of `skipTests`.
2) `styleext` has been deprecated in favor of `style` since the latest is two words.
Fixes#12784
