An Angular Autocomplete From UI to DB

Jun 20, 2018 · Sven Loesekann

To use the MovieManager you need to generate a key from theMovieDB. The documentation is here. To do that you need to create an account und generate a api key. Then you sign in with username, password, api key.

The api key gets stored and used to import movies from theMovieDB.

After that you can login in with username and password and the api key is read of the db.

If you are interested in Angular and Spring have a look at my AngularAndSpring Repo. It is a real project with Angular and Spring with jwt security, i18n, reacitive rest and a few more features.
