This is an implementation of a signup form. Everything was kept as vanilla as possible.
Some remarks:
- Because email validation is a main point, and I consider the Angular email validation sufficient for the front end (depending on the use case), I added an asynchronous validator that checks whether an email address has already been registered on the server. Try "johndoe@gmail.com" as email, it will complain and present a bogus login link.
- There are no protractor tests; don't worry, I am quite proficient if I do say so myself, but unfortunately I don't have the time, especially since I would want to mock out the server and I don't want to add extra dependencies right now. There must be a good solution for this by now, I suppose, but i didn't find it in a minute of Googling.
- Although unit test coverage is now 100%, I do realize that there is not enough testing, especially of the main component validation. I think I would prefer to do that with an e2e testing tool like Protractor (possibly with Cucumber), but see above.
- To do: more elegant user feedback after form submission.
Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.
Run ng test to execute the unit tests via Karma.
