Building a Vue.js 3 Admin Panel from a Video Demo with Replay

TL;DR: Replay reconstructs a fully functional Vue.js 3 admin panel from a video demonstration, providing a behavior-driven approach to UI development.

Building an admin panel is a common task for web developers, often involving tedious setup and repetitive coding. What if you could skip the manual work and generate a working admin panel directly from a video demo? Replay makes this a reality, leveraging video analysis and AI-powered code generation to build UIs based on observed user behavior. Forget static screenshot-to-code; Replay understands intent.

The Problem: Manual Admin Panel Development#

Admin panels typically require a significant amount of boilerplate code for features like:

• •User authentication
• •Data tables
• •Form management
• •Role-based access control
• •Navigation

Manually creating these components is time-consuming and error-prone. Existing UI kits and component libraries help, but still require significant integration and customization. Screenshot-to-code tools offer limited assistance as they only capture visual aspects, missing the underlying functionality and user interaction flow.

Replay: Behavior-Driven Reconstruction#

Replay offers a revolutionary approach: behavior-driven reconstruction. Instead of relying on static images, Replay analyzes video recordings of user interactions with an existing admin panel or a prototype. It then uses this understanding to generate clean, functional code for a Vue.js 3 application (and other frameworks).

Key Features for Admin Panel Generation#

• •Multi-page Generation: Replay can generate entire admin panels with multiple interconnected pages from a single video. This is crucial for complex applications.
• •Supabase Integration: Seamlessly integrate your generated admin panel with Supabase for backend functionality, including authentication and database management.
• •Style Injection: Replay intelligently injects styles to match the look and feel demonstrated in the video, ensuring a visually consistent admin panel.
• •Product Flow Maps: Replay automatically generates a visual map of the user flow within the admin panel, making it easier to understand the application's structure.

Building a Vue.js 3 Admin Panel: A Step-by-Step Guide#

Let's walk through the process of building a Vue.js 3 admin panel from a video demo using Replay.

Step 1: Prepare Your Video Demo#

Create a video recording demonstrating the desired functionality of your admin panel. This could be a screen recording of an existing admin panel, a prototype built with tools like Figma or Adobe XD, or even a hand-drawn mockup.

💡 Pro Tip: Focus on demonstrating key user interactions, such as navigating between pages, creating and editing data, and managing user accounts. The clearer the video, the better the results.

Step 2: Upload Your Video to Replay#

Upload your video file to the Replay platform. Replay supports various video formats (MP4, MOV, etc.).

Step 3: Configure Replay Settings#

Configure the following settings:

• •Framework: Select "Vue.js 3" as your target framework.
• •Backend Integration: Choose "Supabase" if you want to automatically integrate with a Supabase project. Provide your Supabase API URL and API key.
• •Style Injection: Enable style injection to automatically apply styles from the video to your generated admin panel.
• •Page Segmentation: If your video demonstrates multiple pages, Replay will automatically segment them. You can manually adjust these segments if needed.

Step 4: Generate the Code#

Click the "Generate Code" button. Replay will analyze the video and generate the Vue.js 3 code for your admin panel. This process may take a few minutes, depending on the length and complexity of the video.

Step 5: Review and Customize the Code#

Once the code generation is complete, you can review the generated code in the Replay editor. You can also download the code as a ZIP file and import it into your favorite IDE.

📝 Note: The generated code may require some manual adjustments, especially for complex interactions or custom components.

Step 6: Integrate with Supabase (Optional)#

If you chose to integrate with Supabase, Replay will automatically generate the necessary code for user authentication and data management. You'll need to configure your Supabase project to match the data structure used in your admin panel.

Step 7: Run and Test Your Admin Panel#

Run your Vue.js 3 application and test the generated admin panel. Verify that all the features and interactions demonstrated in the video are working correctly.

Example Code Snippets#

Here are some example code snippets that Replay might generate for your Vue.js 3 admin panel:

typescript
// src/components/UserTable.vue
<template>
  <table>
    <thead>
      <tr>
        <th>ID</th>
        <th>Name</th>
        <th>Email</th>
        <th>Role</th>
      </tr>
    </thead>
    <tbody>
      <tr v-for="user in users" :key="user.id">
        <td>{{ user.id }}</td>
        <td>{{ user.name }}</td>
        <td>{{ user.email }}</td>
        <td>{{ user.role }}</td>
      </tr>
    </tbody>
  </table>
</template>

<script setup>
import { ref, onMounted } from 'vue';
import { supabase } from '../supabase'; // Assuming Supabase setup

const users = ref([]);

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

  if (error) {
    console.error('Error fetching users:', error);
    return;
  }

  users.value = data;
});
</script>

typescript
// src/components/LoginForm.vue
<template>
  <form @submit.prevent="handleSubmit">
    <input type="email" v-model="email" placeholder="Email" />
    <input type="password" v-model="password" placeholder="Password" />
    <button type="submit">Login</button>
  </form>
</template>

<script setup>
import { ref } from 'vue';
import { supabase } from '../supabase'; // Assuming Supabase setup

const email = ref('');
const password = ref('');

const handleSubmit = async () => {
  const { error } = await supabase.auth.signInWithPassword({
    email: email.value,
    password: password.value,
  });

  if (error) {
    console.error('Error signing in:', error);
    return;
  }

  // Redirect to admin panel after successful login
  window.location.href = '/admin';
};
</script>

Replay vs. Traditional Methods and Other Tools#

Here's a comparison of Replay with traditional admin panel development methods and other code generation tools:

⚠️ Warning: Replay is not a magic bullet. It may require some manual adjustments and customization, especially for complex applications. However, it significantly reduces the amount of boilerplate code and accelerates the development process.

Addressing Common Concerns#

Concern: The generated code might be messy or inefficient.

Response: Replay generates clean, well-structured code that adheres to Vue.js 3 best practices. While the code may require some optimization, it provides a solid foundation for building a high-performance admin panel.

Concern: Replay might not be able to understand complex interactions.

Response: Replay is constantly improving its ability to understand complex interactions. To improve accuracy, ensure your video demos clearly demonstrate the desired functionality and user flows.

Concern: The generated UI might not match the desired design.

Response: Replay's style injection feature helps to match the look and feel of the video demo. You can further customize the UI by modifying the generated CSS or using a UI library like Vuetify or Element Plus.

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.

How is Replay different from v0.dev?#

Replay focuses on behavior-driven reconstruction from video, understanding user intent and generating functional code. v0.dev generates UI components based on text prompts. Replay excels at capturing complex interactions and product flows demonstrated in video, which v0.dev cannot do.

What kind of videos work best with Replay?#

Videos with clear and deliberate demonstrations of the desired UI functionality and user interactions will yield the best results. Avoid videos with excessive noise, rapid movements, or obscured UI elements.

What frameworks are supported?#

Currently, Replay supports Vue.js 3, React, and plain HTML/CSS. Support for other frameworks is planned for the future.
