How to Reconstruct a CRM from Video to React with Supabase with Replay (2026)

TL;DR: Reconstruct a fully functional CRM interface from a simple screen recording using Replay's video-to-code engine, React, and Supabase for a rapid development workflow.

From Screen Recording to Functional CRM: A 2026 React & Supabase Reconstruction with Replay#

The year is 2026. Building complex applications is still complex, but the initial hurdle of UI creation has been dramatically streamlined. Imagine you have a video walkthrough of a legacy CRM system. Instead of manually dissecting the UI and rebuilding it from scratch, you can now leverage Replay, a behavior-driven reconstruction engine, to generate working React code backed by Supabase, directly from that video.

This approach not only saves significant development time but also ensures a more accurate representation of the original system's intended functionality. Let's dive into how this is possible.

Understanding Behavior-Driven Reconstruction#

Traditional screenshot-to-code tools fall short because they merely capture the visual appearance. They don't understand the user's intent behind each interaction. Replay, on the other hand, analyzes the video feed to understand user behavior, button clicks, form submissions, and navigation flows. This "Behavior-Driven Reconstruction" is the key to creating truly functional code.

Why Video is the Source of Truth#

Video captures the dynamic aspects of a UI, including animations, transitions, and micro-interactions. It provides a richer dataset than static screenshots, allowing Replay to infer the underlying logic and data flow. This is crucial for accurately recreating a complex system like a CRM.

Setting Up Your Environment#

Before we begin, ensure you have the following prerequisites:

• •Node.js and npm installed
• •A Supabase account and project set up
• •Basic familiarity with React and TypeScript

Step 1: Install Dependencies#

Create a new React project using your preferred method (e.g.,

or Vite). Then, install the necessary dependencies for Supabase integration:

bash
npm install @supabase/supabase-js

Step 2: Initialize Supabase Client#

Create a

file to initialize the Supabase client with your project credentials:

typescript
// supabaseClient.ts
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL || '';
const supabaseKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY || '';

export const supabase = createClient(supabaseUrl, supabaseKey);

⚠️ Warning: Never expose your

text

supabaseKey

directly in client-side code in a production environment. Use environment variables and server-side rendering where possible.

Reconstructing the CRM with Replay#

Now comes the magic. Upload your CRM screen recording to Replay. The engine will analyze the video and generate React components, complete with data fetching logic using Supabase.

Step 3: Upload Video to Replay and Generate Code#

1. •Navigate to the Replay platform (https://replay.build).
2. •Upload your CRM screen recording.
3. •Specify the desired output format (React with TypeScript) and database integration (Supabase).
4. •Replay processes the video, identifying UI elements, user interactions, and data flow.

Step 4: Review and Refine the Generated Code#

Replay generates a project structure with React components, Supabase queries, and basic styling. You'll likely need to refine the code, especially the styling and data validation.

Here's an example of a generated React component for displaying customer data:

typescript
// CustomerList.tsx
import React, { useState, useEffect } from 'react';
import { supabase } from './supabaseClient';

interface Customer {
  id: number;
  name: string;
  email: string;
  phone: string;
}

const CustomerList: React.FC = () => {
  const [customers, setCustomers] = useState<Customer[]>([]);

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

      if (error) {
        console.error('Error fetching customers:', error);
      } else {
        setCustomers(data || []);
      }
    };

    fetchCustomers();
  }, []);

  return (
    <div>
      <h2>Customer List</h2>
      <ul>
        {customers.map((customer) => (
          <li key={customer.id}>
            {customer.name} - {customer.email} - {customer.phone}
          </li>
        ))}
      </ul>
    </div>
  );
};

export default CustomerList;

This component fetches customer data from the

table in your Supabase database and displays it in a simple list. Replay automatically infers the data structure and creates the necessary Supabase queries.

Step 5: Implement CRUD Operations#

Replay can also generate code for creating, reading, updating, and deleting data (CRUD operations). For example, a form for adding a new customer might look like this:

typescript
// AddCustomerForm.tsx
import React, { useState } from 'react';
import { supabase } from './supabaseClient';

const AddCustomerForm: React.FC = () => {
  const [name, setName] = useState('');
  const [email, setEmail] = useState('');
  const [phone, setPhone] = useState('');

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();

    const { data, error } = await supabase
      .from('customers')
      .insert([{ name, email, phone }]);

    if (error) {
      console.error('Error adding customer:', error);
    } else {
      // Reset the form
      setName('');
      setEmail('');
      setPhone('');
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <h2>Add New Customer</h2>
      <label>
        Name:
        <input type="text" value={name} onChange={(e) => setName(e.target.value)} />
      </label>
      <label>
        Email:
        <input type="email" value={email} onChange={(e) => setEmail(e.target.value)} />
      </label>
      <label>
        Phone:
        <input type="tel" value={phone} onChange={(e) => setPhone(e.target.value)} />
      </label>
      <button type="submit">Add Customer</button>
    </form>
  );
};

export default AddCustomerForm;

This form allows users to input customer data, which is then inserted into the

table using Supabase.

Key Features of Replay#

• •Multi-Page Generation: Replay can handle multi-page applications, generating code for each page and handling navigation between them.
• •Supabase Integration: Seamlessly integrates with Supabase for data storage and retrieval, including authentication and real-time updates.
• •Style Injection: Injects basic styling based on the video analysis, providing a starting point for customization.
• •Product Flow Maps: Generates visual representations of user flows based on the video, helping you understand how users interact with the application.

Replay vs. Traditional Methods#

💡 Pro Tip: For best results, ensure your screen recording is clear, well-lit, and includes all relevant user interactions.

Benefits of Using Replay#

• •Accelerated Development: Significantly reduces the time required to build UI components.
• •Improved Accuracy: Captures the nuances of user behavior, leading to more accurate reconstructions.
• •Reduced Costs: Lowers development costs by automating repetitive tasks.
• •Enhanced Collaboration: Provides a common understanding of the system's functionality.

Advanced Techniques#

Style Injection and Customization#

Replay injects basic styling based on the video analysis. You can customize the styles using CSS or a CSS-in-JS library like Styled Components or Emotion.

Data Validation and Error Handling#

While Replay generates basic data fetching logic, you'll need to implement robust data validation and error handling to ensure the application's stability and security.

Authentication and Authorization#

Integrate Supabase's authentication features to secure your CRM and control access to sensitive data.

📝 Note: Replay is designed to accelerate the initial UI creation process. You'll still need to write custom business logic and handle edge cases.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features and usage. Paid plans are available for more advanced features and higher usage limits. Check the Replay website for the latest pricing information.

How is Replay different from v0.dev?#

While both tools aim to generate code from visual inputs, Replay focuses on analyzing video to understand user behavior, whereas v0.dev primarily uses static images or design specifications. Replay's behavior-driven approach results in more functional and context-aware code generation.

What types of applications can Replay reconstruct?#

Replay can reconstruct a wide range of applications, including CRMs, dashboards, e-commerce platforms, and internal tools. The quality of the reconstruction depends on the clarity and completeness of the input video.
