As we can see, the Angular SPA Template uses fixed version numbers for all the Angular-related packages; this is definitely a wise choice since we have no guarantees that newer versions will seamlessly integrate with our existing code without raising some potentially breaking issues and/or compiler errors. Needless to say, the version number will naturally increase with the passage of time, because the template developers will definitely try to keep their good work up to date.
That said, these are the Angular packages and releases that will be used within this book:
"@angular/animations": "5.0.2","@angular/common": "5.0.2","@angular/compiler": "5.0.2","@angular/compiler-cli": "5.0.2","@angular/core": "5.0.2", ...
