* feat(hooks): add UseQuery, UseReducer, UseMemo and simplify hook syntax Add new React-style hooks: - UseQuery for async data fetching with caching - UseReducer for complex state management - UseMemo for memoized computations - UseCache for persistent caching Simplify hook usage by adding ViewBase.Hooks.cs with shortcuts that allow calling Use* directly instead of Context.Use* or this.Use*. Updated all CS files and markdown documentation to use the simplified syntax. * refactor(hooks): remove QueryStrategy enum - only had one value * refactor(QueryManager): remove unused QueryEntryState enum * feat(hooks): add KeepPreviousData option for pagination support When enabled, UseQuery keeps showing previous data while fetching with a new key instead of clearing and showing loading state. This prevents UI flicker during list-to-list transitions like pagination. Adds IsPreviousData flag to QueryResult to indicate when displayed data is from a previous query while new data is being fetched. * refactor(hooks): rename IsPreviousData to IsPrevious and reorder QueryResult params * feat(samples): add KeepPrevious pagination demo to QueryApp * feat(samples): add Cache tab with clear examples to QueryApp * fix(hooks): preserve previous value in QueryManager when IsPrevious is set * fix(samples): use expiration in comparison demo for consistent loading behavior * feat(core,content): support custom Build methods for rendering Add automatic detection of Build instance/extension methods for content rendering. Also, ensure widget tree serialization cache is invalidated on child update. * feat(app): add MachineId to AppContext and support Device scope Include MachineId in AppContext and update UseQuery to support Device QueryScope using MachineId for key generation. Prevent QueryScope changes between renders. * refactor(query): rename QueryManager to QueryService Refactor QueryManager to QueryService throughout the codebase. Update related class, method, and option names for consistency. Also generalize query tag types from string to object for greater flexibility. * refactor(query): make QueryResult and QueryMutator generic over key Refactor QueryResult and QueryMutator to accept both value and key generics. Updates all related query/mutation hooks to support explicit key types for improved type safety and flexibility. This is a breaking change for consumers of these APIs. * refactor(query): add scopedKey handling and unify query key usage Refactor QueryService and UseQuery to support scopedKey and serializedScopedKey for more precise and consistent cache keying. * feat(query): add polling & predicate-based invalidation Introduce RefreshInterval option for auto-revalidating queries with active subscribers. Add QueryService methods for predicate-based invalidate/revalidate. Update samples with polling and key-based invalidation demos. * refactor(query): remove TKey from QueryResult and QueryMutator Simplifies QueryResult and QueryMutator generics by removing TKey. Updates all relevant usages and APIs to use a single generic TValue, reducing type complexity and improving code clarity. * feat(products): add Department entity and refactor product dept Introduce Department entity, update Product to reference Department by ID, and refactor related query, form, and seed logic to use Department as a foreign key. Also enhance query key serialization for complex types. * refactor(products): improve ProductDetailsBlade layout and queries Update ProductDetailsBlade to use BladeHelper.WithHeader, adjust skeleton height, and refine query keys. Change Option types in category/department queries to use non-nullable Guid. Fix product mutation/revalidation logic in ProductEditSheet. * refactor(async-select-input): migrate to UseQuery pattern Migrate AsyncSelectInput delegates from Task-based async to a hook-based UseQuery pattern. - Replace AsyncSelectQueryDelegate with AsyncSelectSearchDelegate (renamed) and update signatures to take IViewContext and return QueryResult. - Update all usages, docs, and examples to match new signatures. - Refactor AsyncSelectInputView and related UI to use QueryResult for loading/data states. - BREAKING CHANGE: Existing delegate signatures and usages must be updated. See .releases/Refactors/1.2.6/AsyncSelectInput.md for migration guide. * feat(products): refactor product list to use query cache Refactored ProductsApp to use query-based state and cache management. Introduced IQueryService for cache invalidation by tag, improved list filtering and revalidation, and unified product/category/department option queries. Also updated FilteredListView to use local state for records and loading. * feat(query): add direct tags parameter to UseQuery hooks Allows specifying tags directly in UseQuery calls instead of via QueryOptions. This simplifies usage and improves clarity when associating tags with queries. Existing usages updated to prefer the new tags parameter. * refactor(blades): replace BladeHelper.WithHeader with BladeHeader Replaces the BladeHelper.WithHeader method with the new BladeHeader component used inside a Fragment. Updates docs, samples, and all usages. This is a breaking change�see .releases/Refactors/1.2.6/BladeHeader.md for migration instructions. * refactor(blades): rename IBladeController to IBladeService Rename BladeController and IBladeController to BladeService and IBladeService for consistency with service naming conventions. No API changes; only type names are updated across the codebase and documentation. * refactor(ui): unify dialog and sheet form rendering Introduce ToDialog/ToSheet extensions for consistent form and loading UX. Improve skeletons, async feedback, and code reuse for dialogs/sheets. Removes legacy builders and simplifies WidgetBase extension methods. * feat(inputs): show loading state in AsyncSelectInput Display Loading... placeholder and muted style while async value is loading in AsyncSelectInput. * refactor(query): rename IsLoading/IsValidating to Loading/Validating Update QueryResult and related code to use Loading/Validating/Previous property names instead of IsLoading/IsValidating/IsPrevious for clarity and consistency. Updates all usages and consumers accordingly. * feat(query): add UseQuery docs and CRUD demo apps Add UseQuery concept docs and migration guide. Introduce sample CRUD apps (Products, Categories, Departments) using UseQuery and tag-based cache invalidation. Also, improve AsyncSelectInput loading label handling. * docs(refactors): update UseQuery.md for revised refactor steps Streamline refactor guide by removing redundant examples and clarifying migration steps for UseQuery and related patterns. * refactor(MetricView): use UseQuery hook for data loading BREAKING CHANGE: MetricView now requires a Func<IViewContext, QueryResult<MetricRecord>> hook instead of Func<Task<MetricRecord>>. Update usages to use UseQuery for loading and caching metric data. See .releases/Refactors/1.2.6/MetricView.md for migration details. * refactor(app): replace AppArgs with AppContext in services Update service retrieval to use AppContext instead of AppArgs in OAuthFlowView and DefaultSidebarChrome for consistency. * feat(layout): add individual margin setters to LayoutView Add TopMargin, BottomMargin, LeftMargin, and RightMargin methods for setting margins independently on LayoutView. * feat(bar-chart): set vertical as default layout Change default BarChart layout to vertical and refactor chart extension methods to expression-bodied members for conciseness. * refactor(effects): rename AfterInit to OnMount throughout codebase Replaces all references to EffectTrigger.AfterInit with EffectTrigger.OnMount, and updates related enums, docs, and usages for consistency. Also updates QueryOptions.RevalidateOnInit to RevalidateOnMount. No functional changes. * docs(concepts): update and rename Query doc, add key section Renamed Query.md to 26_Query.md, improved SWR reference, removed best practices/diagrams, and added a placeholder for key explanations. Also updated related links for consistency. * feat(demos): add ChatApp sample and remove ColorsApp Introduce a real-time chat demo with username prompt and message history. Remove the previous ColorsApp sample from demos. * perf(frontend): add structural sharing and memoization for widget tree updates Replace cloneDeep with path-based structural sharing to preserve reference identity for unchanged subtrees. This allows React.memo to skip re-rendering components whose data hasn't changed. Changes: - use-backend.tsx: Replace cloneDeep with clonePathToTarget() that only shallow-clones nodes along the path to the changed node. Unchanged subtrees keep their references, enabling React to bail out early. - widgetRenderer.tsx: Wrap rendering in MemoizedWidget with React.memo that uses reference equality. When a node reference is unchanged, the entire subtree is skipped. - Update components that filter children by displayName to also check for MemoizedWidget's node.type prop (Tabs, Chat, ResizeablePanel, SidebarLayout). Performance characteristics: - Before: O(n) clone + O(n) React diff for every update - After: O(d) clone + O(d) diff where d = depth to changed node This significantly improves update performance for large widget trees, especially in Chrome mode where only the active AppHost typically changes. * Update introduction and query documentation; refactor query handling and improve widget configurations * chore: fix bad docs * chore: better release refactors * chore: add migration guide for use static * chore: correct fversions refs * chore: update docs * chore: add notes about removing this * chore: update use query md * chore: update use query * chore: update links to usequery docs * chore: remove this. * chore: fix bad links * chore: remove oopsie --------- Co-authored-by: rorychatt <pavel.rinne@gmail.com>
