What problem does it solve? Manually verifying the EAF Angular admin UI normally requires the full .NET API and SQL Server stack, which is slow to set up. This Skill lets you stand up the UI against a lightweight Node/Express mock backend so you can test panels like chat, UI customization, and SignalR-dependent features in a browser. ## Core Features & Use Cases - Mock API Setup: Defines the exact endpoints the UI needs (TokenAuth, AbpUserConfiguration, Session, Profile, Chat, UiCustomizationSettings) including required CORS headers. - Runtime Harness Configuration: Guides pointing appconfig.json at the mock, disabling the service worker, and patching SignalR for chat-only tests. - Production Build Verification: Covers serving the production dist with SPA fallback and reverting all temporary patches before final ng build and tsc checks. - Use Case: You changed the chat bar component and want to verify the chat panel, header styling, and theme switching in Chrome without starting the .NET backend or SQL Server. ## Quick Start Set up a mock backend and serve the EAF Angular UI so I can test the chat panel and UI customization page in the browser.
