Create a Headless CMS UI with Replay AI

TL;DR: Replay AI allows you to rapidly prototype and generate a fully functional UI for a headless CMS directly from a screen recording of your ideal user workflow.

Building a UI for a headless CMS can be a time-consuming process. You need to design the interface, handle data fetching and manipulation, and ensure a smooth user experience. Traditional methods often involve wireframing, mockups, and extensive coding, all before seeing a working prototype. What if you could skip many of these steps and jump straight to a functional UI by simply showing what you want?

That's where Replay comes in. Replay leverages the power of video-to-code generation, allowing you to create a working UI for your headless CMS from a screen recording of your desired workflow. This approach, called Behavior-Driven Reconstruction, focuses on what the user is trying to achieve, not just what they see on the screen. It's a paradigm shift from traditional screenshot-to-code tools.

The Problem with Traditional UI Development for Headless CMS#

Developing a usable and efficient UI for a headless CMS presents several challenges:

• •Complexity of Data Management: Headless CMS systems often expose data through APIs, requiring developers to handle data fetching, caching, and state management.
• •User Experience Design: Creating an intuitive and user-friendly interface requires careful planning and design, which can be time-consuming.
• •Integration with Existing Systems: The UI needs to seamlessly integrate with the headless CMS API and any other relevant services.
• •Iterative Development: The process of designing, building, and testing a UI can be iterative, requiring frequent adjustments and refinements.

Replay: A Behavior-Driven Approach to UI Generation#

Replay addresses these challenges by using video as the source of truth. By analyzing a screen recording of your desired UI workflow, Replay can automatically generate the necessary code, including UI components, data fetching logic, and event handlers. This behavior-driven approach allows you to quickly prototype and iterate on your UI, focusing on the user experience rather than the underlying code.

Key Features of Replay for Headless CMS UI Development#

• •Multi-Page Generation: Replay can generate UI across multiple pages, capturing complex workflows. Imagine recording yourself navigating through different sections of your ideal CMS interface – Replay can reconstruct it all.
• •Supabase Integration: Seamlessly integrate with Supabase for data storage and authentication. Replay can generate the necessary API calls and data models to interact with your Supabase backend.
• •Style Injection: Customize the look and feel of your UI by injecting custom CSS or using a styling framework like Tailwind CSS.
• •Product Flow Maps: Visualize the user flow through your UI, making it easier to understand and optimize the user experience. Replay automatically creates these maps from your video.

Comparison with Other UI Generation Tools#

Replay distinguishes itself through its video-first approach and focus on understanding user behavior. Screenshot-to-code tools are limited by the information contained in a single image, while traditional code generation requires significant manual effort.

Building a Headless CMS UI with Replay: A Step-by-Step Guide#

Let's walk through the process of creating a simple UI for managing blog posts in a headless CMS using Replay. We'll assume you have a Supabase project set up with a table called

containing fields like , , and .

Step 1: Record Your Ideal Workflow#

Record a video of yourself interacting with what you want your CMS UI to look like. This could involve:

1. •Navigating to a list of blog posts.
2. •Clicking on a post to view its details.
3. •Editing the post's content.
4. •Creating a new post.
5. •Deleting a post.

The key is to act as if you're interacting with a fully functional UI. Don't worry about the underlying code; Replay will handle that.

💡 Pro Tip: Speak clearly while recording, narrating your actions. This helps Replay better understand your intent.

Step 2: Upload Your Video to Replay#

Upload the video to the Replay platform. Replay will analyze the video and generate a preliminary UI based on your actions.

Step 3: Configure Data Integration#

Connect Replay to your Supabase project. You'll need to provide your Supabase URL and API key. Replay will automatically detect the

table and its fields.

📝 Note: Replay supports various data sources, including REST APIs and GraphQL endpoints.

Step 4: Review and Refine the Generated Code#

Replay will generate React code (or your framework of choice) for the UI. Review the code and make any necessary adjustments. This might involve:

• •Refining the styling of the components.
• •Adding custom validation logic.
• •Optimizing data fetching.

Here's an example of the code Replay might generate for fetching and displaying a list of blog posts:

typescript
// Generated by Replay
import { useEffect, useState } from 'react';
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL;
const supabaseKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY;
const supabase = createClient(supabaseUrl, supabaseKey);

const PostList = () => {
  const [posts, setPosts] = useState([]);

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

      if (error) {
        console.error('Error fetching posts:', error);
      } else {
        setPosts(data);
      }
    };

    fetchPosts();
  }, []);

  return (
    <ul>
      {posts.map((post) => (
        <li key={post.id}>{post.title}</li>
      ))}
    </ul>
  );
};

export default PostList;

This code snippet demonstrates how Replay automatically handles data fetching from Supabase. It uses

to fetch the posts when the component mounts and to store the posts in the component's state.

Step 5: Inject Custom Styles#

Customize the look and feel of your UI by injecting custom CSS or using a styling framework. Replay allows you to easily add CSS classes to the generated components.

For example, you could add Tailwind CSS classes to the

component to style the list:

typescript
// Generated by Replay (with Tailwind CSS)
import { useEffect, useState } from 'react';
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL;
const supabaseKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY;
const supabase = createClient(supabaseUrl, supabaseKey);

const PostList = () => {
  const [posts, setPosts] = useState([]);

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

      if (error) {
        console.error('Error fetching posts:', error);
      } else {
        setPosts(data);
      }
    };

    fetchPosts();
  }, []);

  return (
    <ul className="divide-y divide-gray-200">
      {posts.map((post) => (
        <li key={post.id} className="py-4">
          <a href={`/posts/${post.id}`} className="text-blue-500 hover:text-blue-700">{post.title}</a>
        </li>
      ))}
    </ul>
  );
};

export default PostList;

This code snippet adds Tailwind CSS classes to the

and elements to style the list with dividers and blue links.

Step 6: Iterate and Refine#

The beauty of Replay is that it allows for rapid iteration. If you're not happy with the generated UI, simply record a new video with the desired changes and re-upload it to Replay. The platform will automatically update the code based on your new video.

⚠️ Warning: While Replay significantly speeds up the development process, it's important to review and understand the generated code. You may need to make manual adjustments to ensure the UI meets your specific requirements.
