Replay AI for Building a Manufacturing Execution System UI

TL;DR: Replay AI accelerates the development of Manufacturing Execution System (MES) UIs by automatically generating functional code from video recordings of existing systems or mockups.

The manufacturing industry is undergoing a rapid digital transformation, and Manufacturing Execution Systems (MES) are at the heart of this revolution. However, building and maintaining effective MES UIs can be a significant bottleneck. Traditional methods are time-consuming, error-prone, and often fail to capture the nuanced workflows of the shop floor. What if you could simply record a video of an existing system or a proposed design and have the UI code generated automatically? That's the power of Replay.

The MES UI Development Challenge#

MES UIs are complex beasts. They need to:

• •Track real-time production data
• •Manage work orders and inventory
• •Monitor equipment status
• •Facilitate operator interactions
• •Integrate with various shop floor systems

Building these interfaces from scratch requires significant development effort, deep domain expertise, and constant iteration. Traditional screenshot-to-code tools fall short because they lack the contextual understanding of user behavior and the underlying logic. They only capture the visual appearance, not the intent.

Introducing Replay: Behavior-Driven Reconstruction for MES#

Replay leverages the power of Gemini to revolutionize MES UI development. Unlike traditional tools that rely on static screenshots, Replay analyzes video recordings of existing MES systems or mockups. This "Behavior-Driven Reconstruction" approach allows Replay to understand what users are trying to accomplish, not just what they see on the screen.

Replay analyzes the video, identifies UI elements, infers user interactions, and generates clean, functional code ready to be integrated into your MES platform. This drastically reduces development time, minimizes errors, and ensures the UI accurately reflects the intended workflow.

Key Features for MES UI Development#

• •Multi-Page Generation: MES systems often span multiple screens and workflows. Replay can analyze videos that navigate through different pages and automatically generate the corresponding code for each page.
• •Supabase Integration: Many modern MES implementations utilize Supabase for data storage and real-time updates. Replay can generate code that seamlessly integrates with your Supabase backend, ensuring data consistency and responsiveness.
• •Style Injection: Maintain a consistent look and feel across your MES UI by injecting custom CSS styles during code generation. This ensures that the generated code adheres to your brand guidelines and design standards.
• •Product Flow Maps: Replay can infer the underlying product flow from the video recording, generating visual maps that illustrate the different stages of production and the associated UI elements.

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

Let's walk through the process of using Replay to generate a simple MES UI for tracking work order progress.

Step 1: Record a Video#

Record a video of yourself interacting with an existing MES system or a mockup of the desired UI. The video should clearly demonstrate the workflow for tracking work order progress, including:

• •Selecting a work order
• •Viewing the current status
• •Updating the status
• •Adding notes

💡 Pro Tip: Ensure the video is clear and well-lit. Speak clearly and narrate your actions to provide additional context for Replay.

Step 2: Upload the Video to Replay#

Upload the video to the Replay platform. Replay will automatically analyze the video and identify the UI elements and user interactions.

Step 3: Review and Refine#

Review the generated code and make any necessary refinements. Replay provides a visual editor that allows you to easily adjust the layout, styling, and functionality of the UI.

Step 4: Integrate into Your MES Platform#

Integrate the generated code into your MES platform. Replay supports a variety of popular frameworks and libraries, including React, Vue.js, and Angular.

Example: Generating a Work Order Status Component#

Let's say the video shows a user selecting a work order from a list and then updating its status using a dropdown menu. Replay can generate code similar to the following React component:

typescript
// WorkOrderStatusBar.tsx
import React, { useState, useEffect } from 'react';
import { supabase } from './supabaseClient'; // Assuming Supabase integration

interface WorkOrder {
  id: number;
  orderNumber: string;
  status: string;
}

const WorkOrderStatusBar: React.FC = () => {
  const [workOrders, setWorkOrders] = useState<WorkOrder[]>([]);
  const [selectedWorkOrder, setSelectedWorkOrder] = useState<WorkOrder | null>(null);
  const [status, setStatus] = useState<string>('');

  useEffect(() => {
    const fetchWorkOrders = async () => {
      const { data, error } = await supabase
        .from('work_orders')
        .select('*');

      if (error) {
        console.error('Error fetching work orders:', error);
      } else {
        setWorkOrders(data || []);
      }
    };

    fetchWorkOrders();
  }, []);

  useEffect(() => {
    if (selectedWorkOrder) {
      setStatus(selectedWorkOrder.status);
    }
  }, [selectedWorkOrder]);


  const handleWorkOrderChange = (event: React.ChangeEvent<HTMLSelectElement>) => {
    const orderId = parseInt(event.target.value);
    const order = workOrders.find(wo => wo.id === orderId) || null;
    setSelectedWorkOrder(order);
  };

  const handleStatusChange = async (event: React.ChangeEvent<HTMLSelectElement>) => {
    const newStatus = event.target.value;
    setStatus(newStatus);

    if (selectedWorkOrder) {
      const { error } = await supabase
        .from('work_orders')
        .update({ status: newStatus })
        .eq('id', selectedWorkOrder.id);

      if (error) {
        console.error('Error updating status:', error);
      } else {
        // Optimistically update the UI
        setWorkOrders(workOrders.map(wo =>
          wo.id === selectedWorkOrder.id ? { ...wo, status: newStatus } : wo
        ));
      }
    }
  };

  return (
    <div>
      <h2>Work Order Status</h2>
      <label htmlFor="workOrderSelect">Select Work Order:</label>
      <select id="workOrderSelect" onChange={handleWorkOrderChange}>
        <option value="">-- Select --</option>
        {workOrders.map(order => (
          <option key={order.id} value={order.id}>{order.orderNumber}</option>
        ))}
      </select>

      {selectedWorkOrder && (
        <div>
          <p>Current Status: {selectedWorkOrder.status}</p>
          <label htmlFor="statusSelect">Update Status:</label>
          <select id="statusSelect" value={status} onChange={handleStatusChange}>
            <option value="Pending">Pending</option>
            <option value="In Progress">In Progress</option>
            <option value="Completed">Completed</option>
          </select>
        </div>
      )}
    </div>
  );
};

export default WorkOrderStatusBar;

This code demonstrates how Replay can generate a functional React component that fetches work order data from Supabase, allows the user to select a work order, and update its status. The code is clean, well-structured, and ready to be integrated into your MES application.

📝 Note: This is a simplified example. Replay can generate more complex UI components, including data grids, charts, and custom forms.
