Feature Specification: Integrate SvelteKit
Feature Branch: 004-integrate-svelte-kit
Created: 2025-12-20
Status: Draft
Input: User description: "Integrate SvelteKit into the project"
User Scenarios & Testing (mandatory)
User Story 1 - Seamless Navigation (Priority: P1)
As a user, I want to navigate between different parts of the application (Dashboard, Settings) using standard URL paths so that I can bookmark pages and use the browser's back/forward buttons reliably.
Why this priority: Core application usability and standard web behavior.
Independent Test: Can be tested by clicking navigation links and verifying the URL changes and the correct content renders without a full page reload.
Acceptance Scenarios:
- Given I am on the Dashboard, When I click the "Settings" link, Then the URL changes to
/settingsand the Settings page is displayed. - Given I am on
/settings, When I refresh the page, Then the Settings page is still displayed (not redirected to home).
User Story 2 - Improved Data Loading (Priority: P2)
As a developer, I want to use modern data loading patterns so that data is fetched efficiently before the page renders, reducing layout shifts and loading spinners.
Why this priority: Improves user experience and developer productivity.
Independent Test: Can be tested by observing the page load sequence and verifying that data is available to the component immediately upon mount.
Acceptance Scenarios:
- Given a page requires data from the backend, When the page is navigated to, Then the data is fetched and ready before the content is fully visible.
User Story 3 - Unified Layout (Priority: P3)
As a user, I want a consistent look and feel across all pages with a shared navigation bar and footer.
Why this priority: Visual consistency and ease of use.
Independent Test: Can be tested by navigating between pages and verifying that the header/footer remain static and do not re-render or flicker.
Acceptance Scenarios:
- Given I am navigating between Dashboard and Settings, When the page changes, Then the top navigation bar remains visible and unchanged.
Edge Cases
- Invalid Routes: When a user navigates to a non-existent URL, the system should display a user-friendly 404 error page with a link back to the dashboard.
- API Failures during Load: If the backend API is unavailable during a data load operation, the system should display a graceful error message or redirect to a dedicated error page.
Requirements (mandatory)
Functional Requirements
- FR-001: System MUST use SvelteKit as the primary frontend framework.
- FR-002: System MUST implement file-based routing for all existing pages (Dashboard, Settings).
- FR-003: System MUST be deployable as a Static Single Page Application (SPA) to be served by the existing backend.
- FR-004: System MUST provide a shared layout mechanism for common UI elements (header, footer).
- FR-005: System MUST handle client-side navigation between routes without full page refreshes.
- FR-006: System MUST integrate with the existing backend API for data retrieval.
- FR-007: System MUST support data submission via existing API endpoints using standard asynchronous requests.
Key Entities (include if feature involves data)
- Route: Represents a URL path and its associated page content and data requirements.
- Layout: Represents a shared UI structure that wraps multiple routes.
Success Criteria (mandatory)
Measurable Outcomes
- SC-001: Page transition time between Dashboard and Settings is under 200ms.
- SC-002: 100% of existing frontend functionality is preserved after migration.
- SC-003: Application is accessible via direct URLs (e.g.,
/settings) without manual configuration of the web server for SPA routing. - SC-004: Developer setup time for the frontend is reduced by using standard framework tooling.
Assumptions
- The application will be deployed as a static site served by the Python backend (no Node.js server in production).
- Existing API endpoints are sufficient for the frontend needs.
