RBushWeb.Blazor 0.2.2

RBushWeb.Blazor

Install RBushWeb.Blazor 0.2.2 for .NET 8/.NET 10. The native R-tree browser engine is included as local static assets for interactive WebAssembly and Server.

Typed spatial services

After SpatialProvider.Ready, call SpatialIndex<T>.CreateAsync(module), then insert/upsert SpatialItem<T> values with unique string IDs and finite ordered Envelope bounds. Stable IDs retain native references for identity-safe deletion across C# DTO round trips.

The service supports bulk loading, replacement, intersection search, collision checks, KNN with optional distance/predicate, statistics, validation, clear and snapshots. Search/KNN/snapshot results use complete streamed JSON. Snapshot import validates before replacing the current index and restores the saved branching configuration. Invalid or duplicate input does not partially replace an index.

<SpatialQuery TItem="string" Index="index" Bounds="bounds" Revision="revision">
    <ChildContent Context="items">
        @foreach (var item in items) { <p @key="item.Id">@item.Value</p> }
    </ChildContent>
</SpatialQuery>

Increment Revision after mutating the index so a query component refreshes. Query results are DTO copies; edits must be committed through the service. The sample validates native queries against brute force, nearest-neighbor identity, deletion and snapshot restore.

Full native APIs are available through Module/Handle, including returned function references and synchronous browser callback descriptors. Read INTEGRATION.md for hosting, ownership and publishing. Typed helpers complement native API access; underlying engine compatibility limits still apply.

Lifecycle in 0.2.2

The shared runtime fixes concurrent visual cleanup, callbacks queued before removal, late template imports/root creation and retained cleanup failures. Native Razor factories now return awaitable teardown, coalesce parameter updates and retain roots during synchronous movement. Shared JavaScript/managed regressions and package-restored movement/update/recreation tests run in both sample hosts alongside spatial tests.
