Instruct UI - An AI for Blazor UI Generation
## What's implemented
- Multi-step checkout wizard with Shipping, Payment and Review steps using MudStepper.
- Shipping and payment forms with required fields and data annotations validation (MudForm).
- Masked inputs for card number, expiry and CVC via PatternMask.
- Order summary list with calculated total and simple item models.
- Place Order flow with processing state and Snackbar confirmation.
## Key components
- MudStepper, MudStep
- MudForm, MudTextField, MudSelect, MudCheckBox
- MudGrid, MudItem, MudPaper, MudDivider
- MudList, MudListItem, MudText
- MudButton, MudProgressCircular, MudIcon
- PatternMask, ISnackbar for feedback
## How it works
- ViewModel binding: the page binds a CheckoutViewModel instance using @bind-Value on MudTextField/MudSelect and boolean binding for MudCheckBox.
- Validation: data annotations on CheckoutViewModel drive MudForm validation; the stepper calls _shippingForm.Validate() and _paymentForm.Validate() in HandleStepPreview to prevent forward navigation when invalid.
- Masking and formatting: PatternMask enforces input masks for card number, expiry and CVC fields.
- Order flow: PlaceOrder sets an _isProcessing flag, simulates a network call, shows a Snackbar, and resets stepper and forms with ResetAsync.
## Styling
- Uses MudBlazor components and its utility classes (e.g., d-flex, gap-2, justify-end, pa-4, mt-4) and the Mud theme for spacing and typography.
- Layout relies on MudGrid/MudItem for responsive columns; Mud components adapt to small/medium breakpoints used in xs/md/sm attributes.
## Reuse steps
1. Add the MudBlazor NuGet package and register MudBlazor services in Program.cs (builder.Services.AddMudServices()).
2. Import MudBlazor namespace in the component and ensure _imports.razor includes MudBlazor components.
3. Add the CheckoutViewModel and OrderItemModel to the project and adjust validation attributes as needed.
4. Wire ISnackbar via dependency injection and place a server-side payment integration or tokenization in PlaceOrder.
5. Optionally add theming or localization and secure server endpoints for payment handling.
## Limitations & next steps
- This is a single-page UI scaffold generated by Instruct UI and is editable but not wired to back-end services or a payment gateway.
- No PCI-compliant payment handling is included; replace simulated delay with tokenized payment processing and secure APIs.
- Consider adding address validation, country list sourcing, card tokenization, error handling for network failures, and unit tests for validation logic.
