Overview

Simple Expo React Native application to quickly get started with React Native RealmDb API, based on the starter template that is provided by Realm. I added a few things, specifically working with relationships in RealmDB since it was really what I was looking for before I started to create the video.

📝 Application Notes

• Added relationships so there is a project and a project has mutiple tasks associated with it
• added and additional screen which lists the Projects
• Added React Navigation so that we could move between the screens
• Added a new screen that lists all of the Projects that are in the application
• Added the project name to the task list
• Added the number of tasks associated with the Project to the project list
• Added try catch block to capture errors from the realm.write blocks
• Added code to delete the child Task objects of the Project
• I think that the introduction of the Realm Context is mising some helpful support documentation and links along with how to use the new useQuery function.
• I also think that the documentation on relationships is extremely lacking and I did my best to create something that will show it better
