VSN-2005 : Integrating first phase validation of prepared passengers.
MR Description: First Phase Validation – Frontend Integration
Overview
This merge request delivers the complete frontend integration for the first phase validation of prepared passengers.
The implementation covers the full flow from type definition, endpoint creation, service-level integration, and finally component wiring.
This structured approach ensures that the feature is cleanly designed, type-safe, and seamlessly accessible from the UI.
The purpose of this feature is to provide a reliable client-side mechanism that communicates with the backend endpoint responsible for validating prepared passengers during the first validation phase. This includes establishing clear type signatures, ensuring proper request payload structures, and integrating the feature within the appropriate UI component.
Detailed Changes
1. Method Signature Added to the Store Type Definition
A method signature was added to the store type definition to formally declare the new behavior responsible for handling first phase validation.
This ensures type safety and early validation by the TypeScript compiler.
Key aspects:
- Introduces a strongly typed function that accepts a list of prepared passenger identifiers.
- Defines the expected return type for clarity and consistency.
- Ensures that other parts of the application consuming the store can rely on accurate type information.
This step establishes the foundation for clean API integration and prevents ambiguity across the codebase.
2. Feature Endpoint Definition
A dedicated endpoint related to first phase validation of prepared passengers was added to the application's API layer.
This addition includes:
- A clear and descriptive URL path for the validation action.
- A well-defined HTTP method aligned with the backend contract.
- A consistent interface for performing validation requests across the application.
By isolating the endpoint within the centralized API configuration, the system maintains a clean separation of concerns and stays aligned with best architectural practices.
3. Feature Implementation: Integration Call
The integration layer was extended with the concrete implementation of the validation call.
This includes:
- Invoking the newly defined endpoint.
- Handling request payload formatting.
- Managing asynchronous behavior and error handling.
- Returning the backend response in a predictable and typed structure.
This implementation ensures that the application can communicate with the backend in a stable and maintainable manner.
It also encapsulates all low-level HTTP interaction, keeping components clean and focused on presentation logic.
4. Integration Inside the Validation Component
The final step of this MR is the actual integration of the feature into the component responsible for validations.
This component-level integration includes:
- Invoking the store method that triggers the first phase validation call.
- Handling UI reactions such as loading states or success outcomes.
- Ensuring that the component triggers the validation logic only under appropriate conditions.
- Preparing the component for future enhancements, such as displaying validation results or improving feedback mechanisms.
This step completes the end-to-end functionality, making the validation feature fully operational from the user interface.
Benefits and Impact
-
Full Feature Availability
The frontend now fully supports the first phase validation process, making the feature accessible to end users. -
Improved Maintainability
Clear type definitions, structured endpoint handling, and isolated integration logic improve readability and maintainability. -
Consistency Across the Codebase
Using well-defined method signatures and centralized API calls ensures that future features follow the same architecture. -
Scalability
The store signature and integration approach make it straightforward to extend validation logic or add additional validation phases.
Summary of Added Components
- Type definition update introducing the method signature for first phase validation.
- API endpoint dedicated to triggering prepared passenger validation.
- Integration implementation handling the call to the backend.
- Component-level integration wiring the feature into the UI.
These steps together form a complete and consistent implementation of the first phase validation feature on the frontend.
