DnetIndexedDb VS CarChecker

Blazor WASM was the first, original version. I wanted an app that can work offline, so I decided to save user data in IndexedDB. My first choice for an IndexedDB NuGet was https://github.com/Reshiru/Blazor.IndexedDB.Framework because it was recommended by Steve Sanderson in https://blog.stevensanderson.com/2019/08/03/blazor-indexeddb/ - and it was the worst mistake in the whole project. The NuGet loads all the data from IndexedDB into memory every time you open a connection. That made the app unusably slow after one year of use. I made a few improvements in my own version https://github.com/Jinjinov/IndexedDB.Blazor but I never solved the loading problem. I decided to rewrite the whole project from scratch, using the much better IndexedDB NuGet https://github.com/amuste/DnetIndexedDb . The original project is available at https://github.com/Jinjinov/TheLastTime and as a PWA https://old.ididit.today/ as a lesson on what mistakes to avoid.

I created and 6 offline first WASM apps that are in production use now and quite complex. They all use this Library. I designed my own Sync System around it using .Net Core API CRUD but they have a fully supported Signal R WASM Client now also if you want to try it for yours. https://github.com/amuste/DnetIndexedDb/blob/master/README.md

Have a look at this app: https://github.com/SteveSandersonMS/CarChecker a little older, but the concepts are still relevant. I have a similar use case except user needs the whole database copied locally and synchronized when internet access is restored. I'm concerned with local storage/cache's temporary nature. Looking at Blazor desktop/app models so I can persist to SQLite on disk.

Hi, I am currently working on a similar technical setup . For this I have strongly based on: https://github.com/SteveSandersonMS/CarChecker

The CarChecker demo app by Steve Sanderson leverages an external JavaScript library (idb.js) and Steve wrote a JSInterop wrapper for it, but there's no documentation or instruction of how he added the JavaScript library to the project, while idb.js's github page specifies npm as the primary installation method.
