Replay: AI Generates UI Code for Human Resources Management Systems from Video Guides

TL;DR: Replay generates fully functional HR management system UI code directly from video guides, saving developers time and ensuring accurate replication of desired user workflows.

Human Resources Management Systems (HRMS) are notoriously complex. Building them requires meticulous attention to detail, particularly when replicating specific user workflows and interactions. Traditional methods of UI development, such as manual coding or screenshot-to-code tools, often fall short, leading to inconsistencies and time-consuming debugging. The solution? Leverage AI to understand user behavior and generate code directly from video demonstrations.

The Problem: Replicating HRMS Workflows is a Nightmare#

Imagine you need to implement a new employee onboarding process within your HRMS. You have a video guide showcasing the exact steps a manager takes – filling out forms, assigning training, and setting up access permissions. Traditionally, you'd either:

1. •Manually code the UI: This is time-consuming, error-prone, and requires deep knowledge of the HRMS architecture.
2. •Use a screenshot-to-code tool: These tools only capture visual elements, missing the crucial behavior behind the interaction. They can't understand that a button click triggers a specific workflow or that a form submission updates a database.

The result? Countless hours spent debugging, ensuring consistency, and bridging the gap between the video guide and the actual implementation. HRMS development needs a smarter, more efficient approach.

Replay: Behavior-Driven Reconstruction for HRMS#

Replay is a game-changer. It analyzes video of HRMS workflows and uses AI, powered by Gemini, to reconstruct fully functional UI code. This "Behavior-Driven Reconstruction" approach focuses on understanding what the user is trying to achieve, not just what they see on the screen. This is especially powerful for complex HRMS tasks like:

• •Employee Onboarding
• •Performance Reviews
• •Leave Management
• •Payroll Processing
• •Benefits Enrollment

Replay understands the intent behind each click, form submission, and interaction, ensuring that the generated code accurately reflects the desired user experience.

How Replay Works: A Step-by-Step Guide#

Let's say you have a video demonstrating how to approve a vacation request within your HRMS. Here's how Replay can transform that video into working code:

Step 1: Upload the Video#

Simply upload the video guide to the Replay platform. Replay supports various video formats and resolutions.

Step 2: Replay Analyzes the Video#

Replay’s AI engine analyzes the video, identifying UI elements, user interactions, and underlying data flows. It uses advanced computer vision and natural language processing to understand the context of each action.

Step 3: Generate the Code#

Replay generates clean, well-structured code in your preferred framework (React, Vue, Angular, etc.). It also creates necessary API calls, database interactions, and styling to match the video demonstration.

Step 4: Integrate and Customize#

Integrate the generated code into your HRMS project. Replay provides options for customization, allowing you to fine-tune the UI, modify data handling, and add additional features.

Example: Generating a Vacation Request Approval Form#

Let's assume Replay has analyzed the video. Here's a simplified example of the React code it might generate for the vacation request approval form:

typescript
// React Component for Vacation Request Approval
import React, { useState, useEffect } from 'react';

interface VacationRequest {
  id: number;
  employeeName: string;
  startDate: string;
  endDate: string;
  reason: string;
  status: 'pending' | 'approved' | 'rejected';
}

const VacationRequestApproval = ({ requestId }: { requestId: number }) => {
  const [request, setRequest] = useState<VacationRequest | null>(null);

  useEffect(() => {
    const fetchRequest = async () => {
      const response = await fetch(`/api/vacation-requests/${requestId}`);
      const data = await response.json();
      setRequest(data);
    };

    fetchRequest();
  }, [requestId]);

  const handleApproval = async (status: 'approved' | 'rejected') => {
    if (!request) return;

    await fetch(`/api/vacation-requests/${requestId}`, {
      method: 'PUT',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ ...request, status }),
    });

    setRequest({ ...request, status }); // Update local state
  };

  if (!request) {
    return <div>Loading...</div>;
  }

  return (
    <div>
      <h2>Vacation Request</h2>
      <p>Employee: {request.employeeName}</p>
      <p>Start Date: {request.startDate}</p>
      <p>End Date: {request.endDate}</p>
      <p>Reason: {request.reason}</p>
      <p>Status: {request.status}</p>

      {request.status === 'pending' && (
        <div>
          <button onClick={() => handleApproval('approved')}>Approve</button>
          <button onClick={() => handleApproval('rejected')}>Reject</button>
        </div>
      )}
    </div>
  );
};

export default VacationRequestApproval;

This code includes:

• •Fetching vacation request data from an API endpoint (
  text

  /api/vacation-requests/${requestId}
  ).
• •Displaying the request details.
• •Providing "Approve" and "Reject" buttons that update the request status.

💡 Pro Tip: Replay also generates the corresponding API endpoints and database schema definitions, ensuring a complete end-to-end solution.

Key Features of Replay for HRMS Development#

• •Multi-Page Generation: Replay can handle complex workflows that span multiple pages, such as employee onboarding processes.
• •Supabase Integration: Seamlessly integrate with Supabase for data storage and management.
• •Style Injection: Replay can inject CSS styles to match your existing HRMS design.
• •Product Flow Maps: Visualize the entire user flow, making it easier to understand and maintain complex processes.

This behavior-driven approach is particularly valuable for complex applications like HRMS. Replay can also generate multi-page flows, which is not a primary focus of v0.dev.

What frameworks does Replay support?#

Replay currently supports React, Vue, and Angular. Support for other frameworks is planned for the future.

How secure is Replay?#

Replay uses industry-standard security measures to protect your data. All video uploads and code generation processes are encrypted.

Conclusion#

Replay offers a revolutionary approach to HRMS development by leveraging AI to generate UI code directly from video guides. This behavior-driven reconstruction method saves developers time, improves accuracy, and ensures a consistent user experience. By understanding the intent behind user interactions, Replay bridges the gap between video demonstrations and working code, making HRMS development faster, easier, and more efficient.
