How to Convert UI video to a functional web app using a modern framework like Vue.JS

TL;DR: Replay uses AI-powered video analysis to reconstruct functional Vue.js web applications from screen recordings, understanding user behavior for accurate code generation.

The Future of UI Development: Video-to-Code with Vue.js#

The traditional UI development workflow can be tedious. Manually translating design mockups or user flows into functional code is time-consuming and prone to errors. What if you could simply record a video of the desired UI behavior and have it automatically converted into a working Vue.js application? That's the promise of Replay.

Why Video-to-Code is a Game Changer#

Screenshot-to-code tools have limitations. They only capture the visual aspects of the UI, missing the crucial context of user interactions and application logic. Replay takes a different approach. By analyzing video, it understands what users are trying to achieve, not just what they see. This "Behavior-Driven Reconstruction" results in more accurate and functional code.

Replay leverages the power of Gemini to analyze video recordings of UI interactions and generate clean, functional Vue.js code. This includes:

• •Multi-page generation: Reconstruct complex applications with multiple views and navigation.
• •Supabase integration: Seamlessly connect your UI to a backend database.
• •Style injection: Apply consistent styling based on the video's visual cues.
• •Product Flow maps: Understand and visualize user journeys through the application.

Building a Vue.js App from a Video: A Step-by-Step Guide#

Let's walk through the process of converting a UI video into a functional Vue.js application using Replay. For this example, we'll assume the video showcases a simple to-do list application.

Step 1: Recording the UI Video#

The first step is to record a video of the desired UI behavior. Ensure the video is clear and captures all relevant interactions, including:

• •Adding new tasks
• •Marking tasks as complete
• •Deleting tasks
• •Navigation between pages (if applicable)

💡 Pro Tip: Speak clearly while recording, describing the actions you are taking. This provides additional context for Replay's AI engine.

Step 2: Uploading the Video to Replay#

Once you have your video, upload it to the Replay platform. Replay will then begin analyzing the video and reconstructing the UI.

Step 3: Reviewing and Customizing the Generated Code#

After the analysis is complete, Replay will present you with the generated Vue.js code. This code will include:

• •Vue components for each UI element
• •JavaScript logic for handling user interactions
• •Styling based on the video's visual cues

You can then review and customize the code as needed.

Here's an example of a generated Vue component for displaying a single to-do item:

vue
<template>
  <div class="todo-item">
    <input type="checkbox" :checked="todo.completed" @change="toggleComplete(todo.id)">
    <span :class="{ completed: todo.completed }">{{ todo.text }}</span>
    <button @click="deleteTodo(todo.id)">Delete</button>
  </div>
</template>

<script>
export default {
  props: {
    todo: {
      type: Object,
      required: true
    }
  },
  methods: {
    toggleComplete(id) {
      this.$emit('toggle-complete', id);
    },
    deleteTodo(id) {
      this.$emit('delete-todo', id);
    }
  }
};
</script>

<style scoped>
.todo-item {
  display: flex;
  align-items: center;
  padding: 8px;
  border-bottom: 1px solid #eee;
}

.completed {
  text-decoration: line-through;
  color: #888;
}
</style>

This code snippet demonstrates how Replay generates a Vue component with:

• •A template defining the UI structure (checkbox, text, delete button)
• •Props for receiving data (the
  text

  todo
  object)
• •Methods for handling user interactions (toggling completion, deleting the item)
• •Scoped styling to maintain component-level visual consistency

Step 4: Integrating with Supabase (Optional)#

If your application requires a backend, you can seamlessly integrate Replay with Supabase. Replay can automatically generate the necessary API calls to interact with your Supabase database.

For example, if the video shows the user adding a new to-do item, Replay can generate the following code to save the item to Supabase:

typescript
// Example of Supabase integration
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_ANON_KEY';
const supabase = createClient(supabaseUrl, supabaseKey);

const addTodo = async (text: string) => {
  const { data, error } = await supabase
    .from('todos')
    .insert([
      { text: text, completed: false }
    ]);

  if (error) {
    console.error('Error adding todo:', error);
  } else {
    console.log('Todo added:', data);
  }
};

⚠️ Warning: Remember to replace

text

YOUR_SUPABASE_URL

and

text

YOUR_SUPABASE_ANON_KEY

with your actual Supabase credentials.

Step 5: Running and Deploying the Application#

Once you are satisfied with the generated code, you can run and deploy your Vue.js application using your preferred method.

Benefits of Using Replay for Vue.js Development#

• •Increased Development Speed: Automate the process of translating UI designs into functional code.
• •Improved Accuracy: Reduce errors by letting AI analyze user behavior and generate code accordingly.
• •Enhanced Collaboration: Easily share UI videos and generated code with team members.
• •Reduced Costs: Save time and resources by automating the UI development process.
• •Focus on Core Logic: Free up developers to focus on the more complex aspects of the application.

📝 Note: Replay is constantly evolving, with new features and improvements being added regularly. Stay tuned for future updates!

Real-World Use Cases#

Replay isn't just a theoretical concept; it's being used in a variety of real-world scenarios:

• •Rapid Prototyping: Quickly create interactive prototypes from video recordings of user flows.
• •UI Redesign: Reconstruct existing UIs from videos to facilitate redesign efforts.
• •Accessibility Testing: Analyze video recordings of users interacting with the UI to identify accessibility issues.
• •User Training: Generate interactive tutorials from video recordings of application usage.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited usage. Paid plans are available for more extensive use and access to advanced features. Check the Replay pricing page for details.

How is Replay different from v0.dev?#

While both tools aim to accelerate UI development, Replay distinguishes itself through its video-first approach. v0.dev primarily relies on text prompts and existing codebases. Replay, on the other hand, analyzes video recordings of actual UI interactions, enabling it to capture subtle nuances of user behavior and generate more accurate and functional code. This behavior-driven reconstruction sets Replay apart.

What frameworks does Replay support?#

Currently, Replay primarily supports Vue.js. Support for other popular frameworks like React and Angular is planned for future releases.

What type of videos work best with Replay?#

Clear, well-lit videos with consistent framing and minimal background noise yield the best results. It's also helpful to speak clearly while recording, describing the actions you are taking.

How accurate is the generated code?#

The accuracy of the generated code depends on the quality of the video and the complexity of the UI. Replay's AI engine is constantly improving, and you can always customize the generated code to meet your specific needs.
