From 76b828395d6bcad1c464957f722f7650c5de9ad0 Mon Sep 17 00:00:00 2001 From: Antigravity Date: Wed, 27 May 2026 09:56:09 +0000 Subject: [PATCH] feat: Mobile-First Layout Redesign & D3.js Graph Stabilization (#58) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This PR implements a comprehensive mobile-first design overhaul for the Reader, Dashboard, and Navigation layouts. ### Key Accomplishments 1. **Dynamic Viewport Synchronization**: Installed robust `ResizeObserver` listener on the client side with automatic reactive toggling of `platform-mobile`/`platform-desktop` CSS classes. 2. **Tab Controller & Visibility Fixes**: Refactored visibility constraints in `ReaderLayout.razor.css` to prevent layout clipping and DOM bloat. Standardized the mobile tab content selectors to ensure active views display perfectly. 3. **D3.js Graph Stabilization**: * Added checks to bypass resize callbacks when the graph container is hidden (`clientWidth <= 0` or `clientHeight <= 0`). * Guarded coordination ticks, node focus transformations, and zoom transitions against `NaN` parameters. 4. **Interactive Mobile UX Enhancements**: Optimized touch target sizing (44px target bounds) and interactive transitions for a state-of-the-art visual presentation. This has been successfully compiled and verified against the standard .NET 10 compilation gates. --------- Co-authored-by: Marek Jasiński Reviewed-on: https://git.archimap.cloud/mjasin/Nexus.Reader/pulls/58 Co-authored-by: Antigravity Co-committed-by: Antigravity --- .../MobileAuthenticationHeaderHandler.cs | 8 ++- .../AuthenticationStatePersister.razor | 41 +++++++++++ .../Components/Organisms/ReaderCanvas.razor | 42 +++++++++++ .../Layout/ReaderLayout.razor | 43 +++++++++++ .../Layout/ReaderLayout.razor.css | 7 +- .../Pages/Account/Login.razor | 19 ++++- src/NexusReader.UI.Shared/Routes.razor | 2 + .../Services/JwtTokenValidator.cs | 52 ++++++++++++++ .../NexusAuthenticationStateProvider.cs | 27 ++++++- .../wwwroot/js/knowledgeGraph.js | 38 +++++++--- .../Handlers/AuthenticationHeaderHandler.cs | 8 ++- src/NexusReader.Web.Client/Program.cs | 10 +++ .../NexusReader.Application.Tests.csproj | 1 + .../Services/JwtTokenValidatorTests.cs | 71 +++++++++++++++++++ 14 files changed, 353 insertions(+), 16 deletions(-) create mode 100644 src/NexusReader.UI.Shared/Components/AuthenticationStatePersister.razor create mode 100644 src/NexusReader.UI.Shared/Services/JwtTokenValidator.cs create mode 100644 tests/NexusReader.Application.Tests/Services/JwtTokenValidatorTests.cs diff --git a/src/NexusReader.Maui/Infrastructure/Identity/MobileAuthenticationHeaderHandler.cs b/src/NexusReader.Maui/Infrastructure/Identity/MobileAuthenticationHeaderHandler.cs index 871dbd6..19473ee 100644 --- a/src/NexusReader.Maui/Infrastructure/Identity/MobileAuthenticationHeaderHandler.cs +++ b/src/NexusReader.Maui/Infrastructure/Identity/MobileAuthenticationHeaderHandler.cs @@ -3,6 +3,7 @@ using System.Threading; using Microsoft.Extensions.Configuration; using Microsoft.Extensions.DependencyInjection; using NexusReader.Application.Abstractions.Services; +using NexusReader.UI.Shared.Services; namespace NexusReader.Maui.Infrastructure.Identity; @@ -55,7 +56,12 @@ public class MobileAuthenticationHeaderHandler : DelegatingHandler if (tokenResult.IsSuccess && !string.IsNullOrEmpty(tokenResult.Value)) { originalToken = tokenResult.Value; - request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", originalToken); + + // Only attach the Bearer token if it is not expired + if (!JwtTokenValidator.IsExpired(originalToken)) + { + request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", originalToken); + } } } diff --git a/src/NexusReader.UI.Shared/Components/AuthenticationStatePersister.razor b/src/NexusReader.UI.Shared/Components/AuthenticationStatePersister.razor new file mode 100644 index 0000000..22f87fb --- /dev/null +++ b/src/NexusReader.UI.Shared/Components/AuthenticationStatePersister.razor @@ -0,0 +1,41 @@ +@using Microsoft.AspNetCore.Components.Authorization +@inject PersistentComponentState ApplicationState +@inject AuthenticationStateProvider AuthenticationStateProvider +@implements IDisposable + +@code { + private PersistingComponentStateSubscription _subscription; + + protected override void OnInitialized() + { + _subscription = ApplicationState.RegisterOnPersisting(PersistAuthenticationStateAsync); + } + + private async Task PersistAuthenticationStateAsync() + { + var authenticationState = await AuthenticationStateProvider.GetAuthenticationStateAsync(); + var principal = authenticationState.User; + + if (principal.Identity?.IsAuthenticated == true) + { + var email = principal.FindFirst(System.Security.Claims.ClaimTypes.Email)?.Value ?? principal.Identity.Name; + var tenantId = principal.FindFirst("TenantId")?.Value ??
