How to Rebuild a React Admin Dashboard from Video with Replay and Tailwind CSS

TL;DR: Rebuild a fully functional React admin dashboard from a video recording using Replay, Tailwind CSS, and Supabase, leveraging behavior-driven code generation.

The Problem: From Idea to Interactive Prototype - Fast#

Building a UI from scratch is time-consuming. Iterating on designs, especially for complex applications like admin dashboards, can be a bottleneck. Screenshot-to-code tools offer a superficial solution, but they lack the crucial understanding of user flows and application logic. They generate static visuals, not interactive components. What if you could capture a product demo or a user interaction video and instantly turn it into working code?

That's where Replay comes in.

Replay: Video as the Source of Truth#

Replay uses a revolutionary approach called "Behavior-Driven Reconstruction." Instead of just analyzing pixels, Replay leverages Gemini to understand the intent behind user interactions in a video recording. This allows it to generate not just the visual elements, but also the underlying logic and data connections. This means you can go from a simple video to a working prototype in minutes.

Building a React Admin Dashboard from Video: A Step-by-Step Guide#

Let's walk through rebuilding a React admin dashboard from a video recording using Replay, Tailwind CSS, and Supabase. We'll assume you have a video showcasing the dashboard's key features: user management, data visualization, and settings.

Step 1: Recording and Uploading Your Video#

First, record a video walkthrough of your desired admin dashboard. Focus on demonstrating the key interactions and features. This video will be the blueprint for Replay.

💡 Pro Tip: A clear, well-paced video with distinct UI elements will yield the best results. Speak clearly about the actions you are performing in the video.

Upload the video to Replay. The platform will begin analyzing the video content, identifying UI elements, user interactions, and data flows.

Step 2: Replay Analyzes and Generates Code#

Replay's engine uses Gemini to perform several key tasks:

1. •UI Element Recognition: Identifies buttons, forms, charts, and other UI components.
2. •Interaction Mapping: Understands the relationships between elements based on user actions (e.g., clicking a button triggers a data update).
3. •Code Generation: Generates React components with Tailwind CSS styling based on the identified elements and interactions.
4. •Supabase Integration (Optional): If your video demonstrates data interactions, Replay can automatically generate Supabase queries and mutations.

📝 Note: The quality of the generated code depends on the clarity of the video and the complexity of the interactions.

Step 3: Reviewing and Refining the Generated Code#

Once Replay has finished processing the video, you'll be presented with a code preview. This is where you review the generated code, make adjustments, and refine the UI.

Here's an example of a generated React component for a user table, styled with Tailwind CSS:

typescript
// Generated by Replay
import React, { useState, useEffect } from 'react';
import { supabase } from './supabaseClient'; // Assuming you have a Supabase client

interface User {
  id: string;
  name: string;
  email: string;
  role: string;
}

const UserTable: React.FC = () => {
  const [users, setUsers] = useState<User[]>([]);

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

      if (error) {
        console.error('Error fetching users:', error);
      } else {
        setUsers(data as User[]);
      }
    };

    fetchUsers();
  }, []);

  return (
    <div className="overflow-x-auto">
      <table className="min-w-full divide-y divide-gray-200">
        <thead className="bg-gray-50">
          <tr>
            <th className="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">ID</th>
            <th className="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">Name</th>
            <th className="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">Email</th>
            <th className="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">Role</th>
          </tr>
        </thead>
        <tbody className="bg-white divide-y divide-gray-200">
          {users.map((user) => (
            <tr key={user.id}>
              <td className="px-6 py-4 whitespace-nowrap">{user.id}</td>
              <td className="px-6 py-4 whitespace-nowrap">{user.name}</td>
              <td className="px-6 py-4 whitespace-nowrap">{user.email}</td>
              <td className="px-6 py-4 whitespace-nowrap">{user.role}</td>
            </tr>
          ))}
        </tbody>
      </table>
    </div>
  );
};

export default UserTable;

This code demonstrates several key features:

• •Tailwind CSS Styling: The component is styled using Tailwind CSS classes for a modern and responsive look.
• •Supabase Integration: The component fetches user data from a Supabase database. Replay automatically generated the
  text

  supabase.from('users').select('*')
  query based on the video.
• •Dynamic Data Rendering: The component dynamically renders user data in a table.

Step 4: Style Injection and Customization#

Replay allows you to inject custom styles to further refine the look and feel of your dashboard. You can add custom CSS classes, modify existing styles, or even import entire Tailwind CSS themes.

For example, to change the background color of the table header, you could add the following CSS:

css
/* Custom CSS injected by Replay */
.bg-gray-50 {
  background-color: #f0f0f5; /* A slightly lighter gray */
}

Replay's style injection feature makes it easy to customize the appearance of your dashboard without having to manually edit the generated code.

Step 5: Product Flow Mapping#

Replay generates a product flow map based on the user interactions captured in the video. This map visually represents the navigation paths and dependencies within your dashboard.

This flow map helps you:

• •Understand the overall structure of your application.
• •Identify potential bottlenecks or areas for improvement.
• •Easily navigate between different components and pages.

Step 6: Multi-Page Generation#

Replay supports multi-page generation, allowing you to rebuild entire applications from a single video or a series of videos. The platform automatically identifies page transitions and generates separate components for each page. This is crucial for complex dashboards with multiple views and functionalities.

For example, if your video demonstrates navigating between a user management page, a data visualization page, and a settings page, Replay will generate separate React components for each of these pages, along with the necessary routing logic.

⚠️ Warning: While Replay automates much of the process, manual review and refinement are still necessary, especially for complex applications.

Benefits of Using Replay#

• •Rapid Prototyping: Go from video to working prototype in minutes.
• •Reduced Development Time: Automate the tedious task of UI reconstruction.
• •Improved Collaboration: Easily share and iterate on prototypes with stakeholders.
• •Behavior-Driven Development: Build UIs that are aligned with user behavior.

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 pricing page for the latest details.

How is Replay different from v0.dev?#

While both Replay and v0.dev aim to accelerate UI development, they differ significantly in their approach. v0.dev relies on AI-powered code generation based on text prompts. Replay, on the other hand, uses video analysis to understand user behavior and reconstruct working UIs. Replay focuses on capturing the intent behind the UI, not just the visual appearance. This results in more accurate and functional code generation, especially for complex applications.

What technologies does Replay support?#

Currently, Replay focuses on generating React code with Tailwind CSS styling. Support for other frameworks and libraries is planned for the future. Replay also offers streamlined integration with Supabase for backend data management.

What types of videos work best with Replay?#

Clear, well-paced videos with distinct UI elements work best. Avoid shaky camera work, excessive background noise, and cluttered screens. It's best to narrate what you are doing in the video.
