It assumes prior completion of tutorials on setting up the backend and web front-end, and a properly configured mobile development environment for Android or iOS. The guide walks through creating a new NativeScript project, manually setting up HTML and TypeScript files for various components, and configuring Angular Router for navigation. It highlights differences in UI markup between web and mobile versions, emphasizing the use of StackLayout and other NativeScript-specific tags. The text also addresses potential issues with iOS App Transport Security (ATS) when using HTTP for local development and suggests ways to resolve them. Finally, it mentions the possibility of using Couchbase Mobile components for future development. However, the text concludes with a user reporting a problem with POST requests not working, likely due to localhost issues on Android.
