Summary of Changes

Hello @yennanliu, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on a significant front-end optimization for the employee check-in page. I've aimed to enhance the user experience by giving the page a modern look and feel, improving form interactions, and providing better feedback to the user.

Highlights

• UI Redesign: I've completely revamped the visual layout of the Check-in page, introducing distinct sections for a hero banner, the check-in form, and a features list.
• Real-time Clock: Added a dynamic clock display in the hero section that updates every second, showing the current time and date.
• Enhanced Form & Validation: Improved the check-in form styling with icons and validation feedback (valid/invalid states) for the Employee ID input. The validation now specifically checks for a positive integer.
• Loading State: Implemented a loading state for the check-in button to provide visual feedback while the API request is being processed.
• Improved Alerts: Updated the success and error messages using sweetalert to be more informative, including the checked-in time on success and a clearer error message on failure.

Code Review

The pull request revamps the Check-in page UI, introducing a modern hero section with a live clock, a user-friendly check-in form, and a section highlighting check-in benefits. The script has been updated to support these features.

The review identifies an issue in user ID validation that could lead to runtime errors, a concern regarding the use of an external image URL which poses a risk of UI breakage, and suggestions aimed at improving code maintainability (CSS color management), accessibility (for the loading button), and production code hygiene (removing console logs).

If this.userId is null (its initial state), this.userId?.toString() evaluates to undefined. Calling .trim() on undefined will throw a TypeError.

This can break the validation logic when the component initializes or if the userId field is cleared to null.

const trimmedValue = (this.userId || "").toString().trim();

The hero section background image is loaded from an external URL. Relying on external URLs for critical UI assets in a production environment is risky. If the external resource becomes unavailable, the UI appearance will be broken.

It's recommended to host essential static assets like this background image locally within your project and reference them using a relative path.

This console.log(res) statement appears to be for debugging purposes and should be removed from the codebase before merging to production.

// console.log(res); // Consider removing for production

To enhance accessibility for users relying on assistive technologies, consider adding aria-busy attribute to the button when it's in a loading state. This programmatically informs screen readers that the element is currently updating.

:aria-busy="isLoading"

The CSS uses several hardcoded color values. For better maintainability, it's advisable to define these colors as CSS custom properties (variables).

/* Define at a higher scope, e.g., within #checkin or globally */
#checkin {
  --app-primary-color: #FF385C;
  --app-text-dark: #484848;
  /* ... other color variables ... */
}

/* Usage */
.hero-title {
  /* ... other styles ... */
  color: var(--app-primary-color);
}
