Walkthrough

The PR migrates JavaScript interop calls to FastInvoke, adds nullable-result handling, hardens resource loading and disposal, updates component lifecycle behavior, and adds runtime and static contract tests.

Changes

FastInvoke interop foundation

Layer / File(s) Summary
Runtime dispatch and result contracts
src/BlazorUI/Bit.BlazorUI/Extensions/JsInterop/*
FastInvoke handles invalid runtimes, timeout lifetimes, synchronous exceptions, nullable results, and centralized error reporting. Shared JSON trimming metadata is centralized.
Utility interop wrappers
src/BlazorUI/Bit.BlazorUI/Extensions/JsInterop/UtilsJsRuntimeExtensions.cs
Utility calls use FastInvoke variants. Result-returning helpers expose nullable results.

Extras resource loading

Layer / File(s) Summary
Element scrolling and resource loading
src/BlazorUI/Bit.BlazorUI.Extras/Scripts/Extras.ts, src/BlazorUI/Bit.BlazorUI.Extras/Extensions/JsInterop/ExtrasJsRuntimeExtensions.cs, src/BlazorUI/Bit.BlazorUI.Extras/Components/PhoneInput/BitPhoneInput.razor.cs
The scroll helper targets elements by id. Script and stylesheet loading uses normalized per-resource caches, readiness checks, concurrent or sequential loading, retries, and rejected-cache eviction.

Component resilience

Layer / File(s) Summary
Component interop migration
src/BlazorUI/Bit.BlazorUI.Extras/Components/*, src/BlazorUI/Bit.BlazorUI/Components/Inputs/*, src/BlazorUI/Bit.BlazorUI/Components/Lists/Swiper/*
AppShell, InfiniteScrolling, input controls, and Swiper use FastInvoke while preserving identifiers and arguments.
Nullable geometry and drag handling
src/BlazorUI/Bit.BlazorUI/Components/Surfaces/Splitter/*, src/BlazorUI/Bit.BlazorUI/Components/Surfaces/{Dialog,Overlay,Panel}/*, src/BlazorUI/Bit.BlazorUI.Extras/Components/ProModal/*
Geometry helpers return null on invalid or failed reads. Consumers use zero fallbacks. Splitter drag initialization validates orientation-specific measurements and invalidates stale asynchronous attempts.
Input and file-upload guards
src/BlazorUI/Bit.BlazorUI/Components/Inputs/{DatePicker,DateRangePicker,FileUpload}/*
Date picker disposal releases object references in finally. File upload handles missing files and missing drag-drop references.

Lifecycle cleanup

Layer / File(s) Summary
Managed reference ownership
src/BlazorUI/Bit.BlazorUI/Components/Utilities/{PullToRefresh,SwipeTrap}/*, src/BlazorUI/Bit.BlazorUI/Components/Surfaces/Panel/BitPanel.razor.cs, src/BlazorUI/Bit.BlazorUI/Scripts/Swipes.ts
Components retain reusable .NET object references. JavaScript disposal failures propagate to C# fallback cleanup.
Page visibility teardown
src/BlazorUI/Bit.BlazorUI/Scripts/PageVisibility.ts, src/BlazorUI/Bit.BlazorUI/Utils/BitPageVisibility.cs
Page visibility callbacks are stored and removed by a new JavaScript dispose method. BitPageVisibility implements IAsyncDisposable.

Validation

Layer / File(s) Summary
Runtime behavior tests
src/BlazorUI/Tests/Bit.BlazorUI.Tests/Extensions/JsInterop/IJSRuntimeFastExtensionsTests.cs, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Extensions/JsInterop/IsRuntimeInvalidFrameworkContractTests.cs, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Extras/AppShell/BitAppShellTests.cs
Tests cover synchronous and asynchronous dispatch, exceptions, error hooks, invalid runtimes, framework runtime structure, timeout behavior, and void interop setup.
Static synchronization contract
src/BlazorUI/Tests/Bit.BlazorUI.Tests/Extensions/JsInterop/{TsPromiseMethodScanner,TsPromiseMethodScannerTests,FastInvokeSyncContractTests}.cs
Tests scan TypeScript Promise methods and C# FastInvoke call sites to detect synchronous calls that target asynchronous JavaScript methods.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to a79cc

The PR changes synchronous JavaScript invocation across several components, but failure and state-transition paths can leak a component reference or leave splitter dragging inconsistent, while a contract test may fail unclearly in hosts with missing framework dependencies. These bounded issues should be addressed or explicitly accepted before merging.

Full details: Linked Issues check

Explanation

The PR satisfies issue #9917 by replacing applicable synchronous JS interop calls with FastInvoke or FastInvokeVoid and adding contract tests. The PullToRefresh calls intentionally remain on InvokeVoid because FastInvokeVoid would hide required setup and disposal failures.

Explanation

The PR includes substantial changes beyond the FastInvoke migration in #9917. These include the Extras resource-loader redesign, the scroll API rename, Splitter behavior changes, PageVisibility disposal, and broad component lifecycle changes.

Resolution

Split unrelated behavior changes into separate issue-linked pull requests, or link additional issues that define their scope. Keep this PR limited to the FastInvoke migration and the compatibility, error-handling, null-result, and test changes required by that migration.

7-7: ⚠️ Potential issue | 🟡 Minor

Migrate the remaining BitBlazorUI.Utils wrappers to FastInvoke (they’re synchronous)

src/BlazorUI/Bit.BlazorUI/Scripts/Utils.ts implements getBodyWidth, setProperty, getProperty, getBoundingClientRect, scrollElementIntoView, selectText, and setStyle as non-async functions that directly return values / void (no Promise usage). Update the corresponding UtilsJsRuntimeExtensions.cs methods to use jsRuntime.FastInvoke / FastInvokeVoid instead of Invoke / InvokeVoid for consistency with BitUtilsToggleOverflow.

15-15: ⚠️ Potential issue | 🟠 Major

Type contract mismatch: setup parameter should accept nullable dotnetObj.

The C# side declares DotNetObjectReference<BitPullToRefresh>? as nullable, but the TS setup method parameter is typed as required DotNetObject. The method will crash at runtime when calling dotnetObj.invokeMethodAsync() (lines 38, 64, 71, 75) if null is passed.

While the current call site (BitPullToRefresh.razor.cs:148) always creates a non-null reference, the type contract allows null and should be enforced defensively.

Recommended fix: Make the parameter optional and add a null guard:

dotnetObj: DotNetObject | undefined) {
    if (!dotnetObj) return;

Alternatively, change the C# signature to use non-nullable DotNetObjectReference<BitPullToRefresh> if null should never be passed.

Serialize the tests that mutate OnError.

IJSRuntimeFastExtensions.OnError is process-global. These cases set/reset it per test, so they can race and flake if MSTest parallelization is enabled for the assembly or CI run. Mark this class [DoNotParallelize] or guard the hook with class-level synchronization.

- Around line 44-49: The script-matching currently reduces URLs to pathname only
via the normalize function and then compares normalize(s.src) to targetPath,
which conflates distinct origins and query strings; update the logic so
normalize preserves origin and query (or otherwise compute a full absolute URL
string) when generating targetPath and when comparing against document.scripts,
then use that full URL comparison to find existingTag (refer to the normalize
arrow function, targetPath constant and existingTag lookup) so scripts like
different CDNs or different ?v= queries are considered distinct.

convention so only explicit async functions or those with an explicit Promise
return type are treated as async. Update CollectAsyncJsMethods to stop using
TsReturnsPromiseRegex and only add methods to asyncJsMethods when the method has
the async modifier or its return annotation explicitly contains "Promise";
adjust any test expectations that assumed body-based detection and update

Inline comments:
In
`@src/BlazorUI/Bit.BlazorUI.Extras/Components/Chart/JsInterop/BitChartJsInterop.cs`:
- Around line 28-57: The XML docs on BitChartJsSetupChart and
BitChartJsUpdateChart advertise a false return path that does not exist in the
JavaScript contract. Update the summaries/returns on these methods to match the
actual BitBlazorUI.BitChart.setupChart and BitBlazorUI.BitChart.updateChart
behavior: either remove the false case and document null for failure on the
fast/in-process path, or change the JS implementation to return false instead of
throwing so the contract is consistent.

In `@src/BlazorUI/Bit.BlazorUI/Components/Surfaces/Panel/BitPanel.razor.cs`:
- Around line 260-273: The disposal logic in BitPanel’s teardown path only
releases _dotnetObj inside the JSDisconnectedException handler, so a normal
JSException can leak the GCHandle and keep the component alive. Update the
try/catch around _js.BitSwipesDispose in BitPanel to also dispose _dotnetObj
before rethrowing on non-disconnect failures, and clear the _dotnetObj field on
the successful JS ownership path after BitSwipesDispose completes.

In
`@src/BlazorUI/Bit.BlazorUI/Components/Utilities/PullToRefresh/BitPullToRefresh.razor.cs`:
- Around line 245-265: Ensure the failure path in BitPullToRefresh.DisposeAsync
still executes the base cleanup: the catch-all around BitPullToRefreshDispose
currently rethrows before base.DisposeAsync(disposing) can run. Update
BitPullToRefresh.DisposeAsync so the managed _dotnetObj release still happens on
errors, but base.DisposeAsync(disposing) is always awaited from the failure path
before propagating the exception.

In `@src/BlazorUI/Bit.BlazorUI/Components/Utilities/SwipeTrap/BitSwipeTrap.ts`:
- Around line 166-173: `BitSwipeTrap.dispose()` is swallowing failures from
`dotnetObj.dispose()`, which hides JS-to-.NET handoff errors. Update the
`dispose` method to stop catching and only logging the exception; instead, let
the disposal failure surface so the matching `BitSwipeTrap.razor.cs` cleanup
paths can handle `_dotnetObj` correctly.

In
`@src/BlazorUI/Tests/Bit.BlazorUI.Tests/Extensions/JsInterop/FastInvokeSyncContractTests.cs`:
- Around line 158-217: `ResolveConstStringIdentifier` is using brace counting
and a file-wide name fallback that can pick the wrong `const string` when braces
appear in strings/comments or when another member/type has the same name. Update
`ResolveConstStringIdentifier` and `IsDeclarationInScopeAt` to use syntax-aware
scope detection from the C# source instead of raw text scanning, and restrict
resolution to the declaration that is actually visible at the call site. Remove
or tighten the broad fallback so it cannot bind a same-named const from an
unrelated scope.

In
`@src/BlazorUI/Tests/Bit.BlazorUI.Tests/Extensions/JsInterop/TsPromiseMethodScanner.cs`:
- Around line 37-44: The raw regex scans in TsPromiseMethodScanner can falsely
match class and static method text inside comments or strings, which can add
bogus Class.Method entries to the map used by FastInvokeSyncContractTests.
Update the scanning logic around TsClassRegex and TsStaticMethodHeaderRegex to
ignore non-code content before matching, or replace the regex approach with a
real parser, and add a regression test covering commented-out or quoted
signatures.

57-57: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Throw an Error object here instead of a string. A primitive throw drops the standard error shape and stack, which makes this JS interop failure harder to diagnose.

In
`@src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Extras/AppShell/BitAppShellTests.cs`:
- Around line 738-739: The AppShell tests have incomplete bUnit JSInterop setups
for awaited void calls, so the setups for BitBlazorUI.AppShell.initScroll,
BitBlazorUI.AppShell.afterRenderScroll, and BitBlazorUI.AppShell.disposeScroll
should all be completed with SetVoidResult(), while keeping
BitBlazorUI.AppShell.locationChangedScroll unchanged because it is
fire-and-forget. Update the relevant JSInterop.SetupVoid calls in
BitAppShellTests so every awaited AppShell interop invocation is fully
configured.

In
`@src/BlazorUI/Tests/Bit.BlazorUI.Tests/Extensions/JsInterop/IsRuntimeInvalidFrameworkContractTests.cs`:
- Around line 92-97: `CreateFrameworkRuntime` is instantiating an internal
runtime type with the default Activator overload, which can fail for
`UnsupportedJavaScriptRuntime` because its parameterless constructor is
non-public. Update the `Activator.CreateInstance` call in
`CreateFrameworkRuntime` to use the overload that allows non-public
constructors, so the prerender test can construct the framework runtime
successfully.

Inline comments:
In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/Chart/BitChart.razor.cs`:
- Around line 30-34: The XML doc comment on BitChart should no longer imply that
this first-render callback is the right place to register plugins or custom JS
options, since BitChartJsSetupChart(Config) has already been attempted by then.
Update the remarks on the first-render callback in BitChart.razor.cs to either
remove that guidance or clearly state that plugin/custom option registration
must happen before first render or before Config is assigned.

In `@src/BlazorUI/Bit.BlazorUI.Extras/Scripts/Extras.ts`:
- Around line 244-255: The classic script reuse path in findExistingResource is
too permissive and can match <script nomodule> tags that will not execute in
module-capable browsers. Update the script branch in Extras.findExistingResource
so the non-module predicate also excludes noModule host scripts, while keeping
the existing type and load-failure checks intact.

In
`@src/BlazorUI/Bit.BlazorUI/Components/Inputs/ColorPicker/BitColorPickerJsRuntimeExtensions.cs`:
- Around line 8-13: The setup helper currently hides a failed JS setup by
returning an empty string, which can prevent later disposal of the
DotNetObjectReference. Update
BitColorPickerJsRuntimeExtensions.BitColorPickerSetup to preserve the nullable
failure state from FastInvoke or explicitly dispose the BitColorPicker reference
when setup returns no id, and make BitColorPicker.razor.cs handle that case
before storing _abortControllerId so BitColorPickerDispose can still clean up
correctly.

In `@src/BlazorUI/Bit.BlazorUI/Components/Surfaces/Panel/BitPanel.razor.cs`:
- Around line 170-175: The swipe setup in BitPanel creates _dotnetObj before
calling BitSwipesSetup, but if that JS call throws the reference is left
undisposed and can leak. Update the BitPanel.razor.cs setup flow so the
DotNetObjectReference created in the swipe initialization path is disposed when
BitSwipesSetup fails, and only kept for later cleanup on the success path
handled by DisposeAsync.

In `@src/BlazorUI/Bit.BlazorUI/Scripts/Swipes.ts`:
- Around line 259-264: The disposal block in Swipes.ts is swallowing failures
from dotnetObj.dispose() and then clearing the reference, which hides teardown
errors and removes any retry path. Update the dispose/cleanup logic in the
relevant method to let the exception surface instead of catching and logging it,
keeping behavior consistent with the other disposal paths in this cohort. Make
sure the dotnetObj cleanup in this section preserves the failure signal before
setting dotnetObj to undefined.

126-129: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

assembly.GetTypes() can throw instead of reporting inconclusive.

GetTypes() forces resolution of every type in the assembly. If a transitive dependency of the framework assembly is missing in the test host, it throws ReflectionTypeLoadException, which fails the test rather than skipping it. That contradicts the inconclusive strategy documented above. SingleOrDefault also throws InvalidOperationException if two types share the simple name.

Use a targeted lookup and keep the inconclusive path.

♻️ Proposed refactor
-        var type = assembly.GetTypes().SingleOrDefault(t => t.Name == typeName);
+        Type? type;
+        try
+        {
+            type = assembly.GetTypes().FirstOrDefault(t => t.Name == typeName);
+        }
+        catch (ReflectionTypeLoadException ex)
+        {
+            type = ex.Types.FirstOrDefault(t => t is not null && t.Name == typeName);
+        }
+
         Assert.IsNotNull(type,
             $"Could not find framework runtime '{typeName}' in assembly '{assemblyName}'. " +

the existing token check and only store measurements in

allowing setup failures to propagate so BitPullToRefresh.DisposeAsync can
release _dotnetObj when JavaScript never takes ownership.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

End an active drag when Vertical changes.

If Vertical changes after a drag starts, _isDragging remains true. OnDragging then uses the new axis with baselines measured for the old axis. This can set pane dimensions from stale or default values.

Invalidate the drag token and clear _isDragging before scheduling the pane reset.

Proposed fix
 private void OnSetVertical()
 {
+    unchecked { _dragToken++; }
+    _isDragging = false;
+    ClassBuilder.Reset();
+
     _ = InvokeAsync(ResetPaneDimensionsOnVerticalChange)

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Release _dotnetObj when BitSwipeTrapSetup fails.

If setup throws before BitSwipeTrap.ts registers the trap at Lines 122-137, this method leaves _dotnetObj allocated. Later, BitSwipeTrap.ts returns for an unknown id at Lines 140-142, so DisposeAsync sees a successful no-op and does not run its fallback cleanup. The reference can keep the component rooted.

Catch setup failures, dispose and clear _dotnetObj, then rethrow the original exception.

 _dotnetObj = DotNetObjectReference.Create(this);
-await _js.BitSwipeTrapSetup(
-    UniqueId,
-    RootElement,
