Ported from the owner's b2b.next and adapted from MudBlazor to the daisyUI
components:
- LocalizableComponentBase provides CascadingState, Navigation, Toast,
IsLoading/IsDefaultDisabled, WhenOnline/StartOnlinePolling, and after-render
jobs that actually run.
- CascadingState starts with initialised state and polls the online status
with a PeriodicTimer. It reports errors through ILoggingService plus a toast,
and disposes what it holds.
- New pieces:
- ToastService + ToastHost, the snackbar, with AddResponseError/Success/
Warning/Exception in SUtility;
- ErrorViewer, which shows the validation messages plus AdditionalError(s);
- LoggingService, which writes to the console and the IndexedDB client log.
- HttpService is rebuilt and registered:
- auth levels Get/Post/Delete, *Anon and *TotallyAnon;
- retry with backoff;
- classified failures (FailureCodes) instead of exceptions;
- HTTP 410 on cancel;
- the "default" client.
ReadWebResult and DefaultReadFromJsonAsync read its responses.
- ClientJsonContext is source-generated, and SUtility.DefaultSerializer and
Blazored.LocalStorage use it.
- WebResult gains a C# 14 IsInvalid extension property.
The code follows the imported rules:
- Every service and async helper takes a CancellationToken last.
- Primary constructors replace constructor-plus-fields.
- MessagesService and IStorage return Task<WebResult> / Task<List<T>>.
MessagesService is still mock, building its results in memory; the seed
feed and thread moved to Faker.
- Index and ExpandMessage follow the page pattern: an offline guard with
WhenOnline, LoadData, and early returns with toasts on the results they used
to ignore. ExpandMessage reloads on route change and shows "not found"
instead of a null message.
- Model and state collections are [], and the fake identity defaults moved
out of the models.
- Components:
- no ?. chains over initialised state;
- [Inject] instead of @inject;
- IsDefaultDisabled on the actions;
- autocomplete on every text input;
- Localizer[key, args] instead of string.Format;
- the localizer no longer leaks its inner _pLocalizer.
- Settings → General gains a language picker (English/Italiano), and
SetDefaultCulture limits the culture to those two.
Bugs fixed along the way:
- A compose with untouched (null) content passed the empty check.
- File errors were joined with <br/> and rendered as markup.
- ClientLogs.ErrorMessage() threw on warnings.
- CoalescingStringLocalizer[key, args] showed a raw "{0}" for missing keys.
- AppStatusService exposed a call to a JS function that doesn't exist.
