Create Database or API to save data when using Angular 6+ Apps

There are about 6 Angular 6+ applications from this template [login to view URL] that I setup in the Fuse Skeleton file. I had asked the creator a question about the best way to save data for this template. I included his response at the very bottom. The fake-db implementations mentioned, include several typescript files that serve fake data to each of the applications. This populates the applications with data for demonstration purposes only. I would like to be able to add and delete data to and from this Angular 6 template using the applications that I currently have setup. I have included two zipped files with this project to better understand what I am asking. "Fuse Skeleton" is the project that I would like to be able to save data locally from. "Fuse Demo" is the original template with all apps and functionality. Please read his response and help me understand what my options are for saving data. At this time, being able to save data is my only request. Developers Response 1. Calendar and Contacts also have save/delete functionality. We use a package called angular-in-memory-web-api which allows us to have a data coming from json format. That package basically intercepts all outgoing traffic and serves data from our fake-db implementation. There are no database connected to the app. But all the functionality is in there so it's just a matter of creating a real API endpoints and connecting them to apps. Of course you would need some modifications along the way but it will be faster and easier than setting up everything from scratch.
