Replay: Building UI for Content Management Systems Using Video Analysis

TL;DR: Replay reconstructs fully functional UI code for content management systems directly from video demonstrations, streamlining development and enhancing user experience.

Content management systems (CMS) are the backbone of countless websites and applications. Building and maintaining their user interfaces can be a complex and time-consuming process. Traditional approaches often involve manual coding, design iterations, and extensive testing. What if you could drastically reduce this effort and create robust UI components directly from video demonstrations? That's the power of Replay.

The Challenge: UI Development for CMS Platforms#

Developing a CMS UI presents unique challenges:

• •Complexity: CMS platforms often require intricate interfaces to manage various content types, user roles, and settings.
• •Customization: Developers frequently need to adapt the UI to specific client requirements and branding guidelines.
• •Maintenance: As CMS platforms evolve, maintaining and updating the UI can become a significant burden.
• •Consistency: Ensuring a consistent user experience across different sections of the CMS is crucial for usability.

Existing UI development tools often fall short when addressing these challenges. Screenshot-to-code solutions, for instance, lack the ability to understand user intent and behavior. They merely generate static representations of the UI, requiring significant manual effort to add functionality and interactivity.

Introducing Replay: Behavior-Driven UI Reconstruction#

Replay is a revolutionary video-to-code engine that leverages Gemini to reconstruct working UI from screen recordings. Unlike screenshot-to-code tools, Replay understands what users are trying to do, not just what they see. This "Behavior-Driven Reconstruction" approach treats video as the source of truth, enabling the generation of fully functional UI components with minimal manual intervention.

Key Features of Replay for CMS UI Development:#

• •Multi-page generation: Replay can analyze multi-page flows within a CMS, generating code for entire workflows, not just individual screens.
• •Supabase integration: Seamlessly integrate your CMS UI with Supabase for data management and authentication.
• •Style injection: Inject custom styles and themes to match your CMS branding guidelines.
• •Product Flow maps: Visualize user flows within the CMS to identify areas for optimization.

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

Let's walk through the process of using Replay to build a UI for a simple blog post management section within a CMS.

Step 1: Record a Video Demonstration#

Record a video demonstrating the desired user flow. For example, you might record yourself:

1. •Logging into the CMS.
2. •Navigating to the "Posts" section.
3. •Creating a new blog post.
4. •Adding a title, content, and featured image.
5. •Saving and publishing the post.

📝 Note: The more detailed and comprehensive the video, the better Replay will be able to understand the user intent and reconstruct the UI.

Step 2: Upload the Video to Replay#

Upload the video to the Replay platform. Replay will then analyze the video and extract key information about the UI elements, user interactions, and data flow.

Step 3: Review and Refine the Generated Code#

Replay will generate code for the UI based on the video analysis. Review the generated code and make any necessary refinements. You can adjust the styling, add custom logic, and integrate the UI with your existing CMS backend.

Step 4: Integrate with Your CMS#

Integrate the generated UI code into your CMS. This may involve copying and pasting the code into your CMS template files or using a CMS plugin to import the UI components.

Example: Generating a "Create Post" Form#

Let's say you've recorded a video of creating a new blog post in your CMS. Replay might generate code similar to the following:

typescript
// React component for creating a new blog post
import React, { useState } from 'react';
import { supabase } from './supabaseClient'; // Assuming Supabase integration

const CreatePostForm = () => {
  const [title, setTitle] = useState('');
  const [content, setContent] = useState('');
  const [featuredImage, setFeaturedImage] = useState(null);

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

    try {
      // Upload the image to Supabase storage (example)
      const { data, error } = await supabase.storage
        .from('images')
        .upload(`public/${featuredImage.name}`, featuredImage, {
          cacheControl: '3600',
          upsert: false,
        });

      if (error) {
        console.error('Error uploading image:', error);
        return;
      }

      const imageUrl = `https://your-supabase-url.co/${data.Key}`;

      // Create the post in Supabase database
      const { data: postData, error: postError } = await supabase
        .from('posts')
        .insert([
          { title, content, featured_image: imageUrl },
        ]);

      if (postError) {
        console.error('Error creating post:', postError);
        return;
      }

      // Reset the form
      setTitle('');
      setContent('');
      setFeaturedImage(null);

      alert('Post created successfully!');
    } catch (error) {
      console.error('An error occurred:', error);
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="title">Title:</label>
        <input
          type="text"
          id="title"
          value={title}
          onChange={(e) => setTitle(e.target.value)}
          required
        />
      </div>
      <div>
        <label htmlFor="content">Content:</label>
        <textarea
          id="content"
          value={content}
          onChange={(e) => setContent(e.target.value)}
          required
        />
      </div>
      <div>
        <label htmlFor="featuredImage">Featured Image:</label>
        <input
          type="file"
          id="featuredImage"
          onChange={(e) => setFeaturedImage(e.target.files[0])}
        />
      </div>
      <button type="submit">Create Post</button>
    </form>
  );
};

export default CreatePostForm;

This code provides a functional React component for creating a new blog post, including input fields for the title, content, and featured image, as well as a submit button. It also demonstrates integration with Supabase for image storage and data management.

💡 Pro Tip: Replay can also generate code for other UI frameworks, such as Vue.js and Angular.
