Are there any starter projects or example projects anyone knows of that use Angular 2+ as SPA and have some basic code wired up for logging in and signing up?
All the Live Demos with Auth are listed in the Auth Docs.
http://angular.techstacks.io is the only Live Demo built with Angular, but it was built with Angular 1.x. Whilst the Angular code may be out dated, the Auth APIs have remained the exactly same (which are used by all Apps) so the HttpBenchmarks Auth Guide is still relevant.
The new TechStacks at https://techstacks.io was built with the more modern Vue + Nuxt + Vuetify SPA stack.
Thank you, I will check them out
