Question 1

How to set up DnetIndexedDb in a Blazor WebAssembly project?

Accepted Answer

Install the NuGet package, add the required JavaScript scripts to index.html after Blazor references, create a class derived from IndexedDbInterop, and register it in ConfigureServices with a database model. The README provides step-by-step code examples for this process.

Question 2

Is DnetIndexedDb better than writing JavaScript interop code directly for IndexedDB?

Accepted Answer

DnetIndexedDb offers a type-safe, .NET-native API that reduces boilerplate and errors, making it ideal for teams familiar with EF Core. However, for simple one-off operations or developers comfortable with JavaScript, direct interop might be lighter and faster.

Question 3

Can DnetIndexedDb handle database migrations or schema changes?

Accepted Answer

IndexedDB supports versioning for schema upgrades, and DnetIndexedDb allows incrementing the version in IndexedDbDatabaseModel. However, it lacks built-in migration tools like EF Core, so developers must manually handle data transformations during upgrades.

Question 4

What are the performance impacts of using DnetIndexedDb in Blazor apps?

Accepted Answer

Since all operations go through JavaScript interop, there's overhead compared to pure JavaScript, especially for frequent or large data transactions. Optimize by batching calls or limiting real-time queries to avoid UI lag.

Question 5

How to query data by a non-key index in DnetIndexedDb?

Accepted Answer

Use the GetByIndex method, specifying the store name, index name, and range parameters. For example, to get items by 'fieldVisualName', call GetByIndex with the index name and bounds, as shown in the API examples with TableFieldDto.

Question 6

Does DnetIndexedDb work with Blazor Server or only WebAssembly?

Accepted Answer

It's compatible with both Blazor Server and Blazor WebAssembly, as stated in the README. Ensure the JavaScript files are included, and note that server-side usage might have latency due to interop over SignalR.
