 Not Busy App is an Angular 9 web app which requires the user’s location. Using the location we query some basic data using the “not-busy-backend” api (also public source). This API returns a list of places and their relevant “popularity” data. Subsequent searches of this api can also include a keyword to filter resulting places. Authenticated users can “heart” (favourite) and save a specific set of places, to be retrieved and popular-time data gathered in realtime.
