Building Vue 3 Components from Figma Prototype Videos

TL;DR: Stop manually translating Figma prototypes into Vue 3 components; Replay uses video analysis to automatically generate functional code, understanding user behavior and intent, saving developers countless hours.

The age of pixel-perfect hand-coding from static design mockups is OVER. We've all been there: painstakingly translating Figma prototypes into functional Vue 3 components, battling inconsistencies, and losing precious time on repetitive tasks. But what if you could skip the manual labor and jump straight to working code? Enter Replay, a game-changing video-to-code engine.

The Problem with Traditional Design-to-Code#

Traditional design-to-code workflows are fundamentally broken. Static prototypes, while visually appealing, lack the dynamic behavior and user intent that drive real-world applications. This disconnect leads to:

• •Implementation Gaps: Designs often don't account for edge cases, error handling, or dynamic data updates.
• •Communication Overhead: Constant back-and-forth between designers and developers to clarify intended behavior.
• •Wasted Time: Tedious manual coding of UI elements that are already visually defined.
• •Inconsistent User Experience: Discrepancies between the intended design and the final implementation.

Screenshot-to-code tools offer a marginal improvement, but they are limited by their inability to understand the purpose behind the design. They only see pixels, not actions.

Behavior-Driven Reconstruction: The Replay Advantage#

Replay takes a radically different approach: Behavior-Driven Reconstruction. Instead of relying on static images, Replay analyzes video recordings of Figma prototypes to understand user interactions, state transitions, and overall application flow. By treating the video as the source of truth, Replay can generate Vue 3 components that accurately reflect the intended behavior and user experience.

Replay leverages the power of Gemini to understand the nuances of user interactions within the video, enabling it to generate code that is not only visually accurate but also functionally complete.

Building Vue 3 Components from Figma Prototype Videos: A Step-by-Step Guide#

Let's walk through a practical example of building Vue 3 components from a Figma prototype video using Replay. We'll assume you have a Figma prototype with a basic user authentication flow (login/register).

Step 1: Record Your Figma Prototype#

Record a video of yourself interacting with your Figma prototype. Be sure to demonstrate all the key interactions, state changes, and navigation flows. For example:

• •Clicking the "Login" button
• •Entering valid and invalid credentials
• •Navigating to the "Register" page
• •Submitting the registration form
• •Handling error messages

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

Step 2: Upload Your Video to Replay#

Navigate to the Replay platform and upload your video recording. Replay will automatically analyze the video and begin reconstructing the UI components.

Step 3: Review and Refine the Generated Code#

Once the analysis is complete, Replay will present you with a set of generated Vue 3 components. Review the code carefully, paying close attention to:

• •Component Structure: Ensure the components are logically organized and named appropriately.
• •Data Binding: Verify that data is correctly bound to the UI elements.
• •Event Handling: Confirm that event listeners are properly attached to the interactive elements.
• •State Management: Check that state transitions are handled correctly.

You can directly edit the generated code within the Replay interface to make any necessary adjustments.

Step 4: Integrate with Your Vue 3 Project#

Download the generated Vue 3 components and integrate them into your existing project. You may need to adjust the styling to match your application's design system.

Here's an example of a generated Vue 3 component for a login form:

vue
<template>
  <form @submit.prevent="login">
    <div>
      <label for="email">Email:</label>
      <input type="email" id="email" v-model="email" required />
    </div>
    <div>
      <label for="password">Password:</label>
      <input type="password" id="password" v-model="password" required />
    </div>
    <button type="submit">Login</button>
    <p v-if="errorMessage" class="error">{{ errorMessage }}</p>
  </form>
</template>

<script>
import { ref } from 'vue';

export default {
  setup() {
    const email = ref('');
    const password = ref('');
    const errorMessage = ref('');

    const login = async () => {
      try {
        // Simulate API call
        const response = await fetch('/api/login', {
          method: 'POST',
          body: JSON.stringify({ email: email.value, password: password.value }),
          headers: {
            'Content-Type': 'application/json'
          }
        });

        if (!response.ok) {
          const error = await response.json();
          errorMessage.value = error.message;
          return;
        }

        // Handle successful login
        console.log('Login successful!');
      } catch (error) {
        errorMessage.value = 'An error occurred during login.';
      }
    };

    return {
      email,
      password,
      errorMessage,
      login
    };
  }
};
</script>

<style scoped>
.error {
  color: red;
}
</style>

📝 Note: Replay can also generate code tailored for specific UI libraries like Vuetify or Element Plus.

Step 5: Connect to Your Backend (Supabase Integration)#

Replay seamlessly integrates with Supabase, allowing you to easily connect your generated Vue 3 components to your backend. Replay can automatically generate the necessary API calls and data models based on your Supabase schema.

typescript
// Example of fetching data from Supabase using Replay-generated code
import { supabase } from './supabaseClient';

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

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

  console.log('Fetched data:', data);
  return data;
};

⚠️ Warning: Always sanitize user inputs to prevent security vulnerabilities like SQL injection.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features. Paid plans are available for more advanced functionality and higher usage limits.

How is Replay different from v0.dev?#

v0.dev primarily focuses on generating UI components from text prompts. Replay, on the other hand, analyzes video recordings of user interactions to understand behavior and intent, leading to more accurate and functional code generation. Replay also offers features like multi-page generation and Supabase integration, which are not available in v0.dev.

What types of Figma prototypes work best with Replay?#

Replay works best with prototypes that clearly demonstrate user interactions, state changes, and navigation flows. The more detailed and comprehensive the video recording, the better the generated code will be.

What if the generated code isn't perfect?#

Replay is designed to generate a solid foundation of working code. You can then refine and customize the code to meet your specific needs. The goal is to significantly reduce the amount of manual coding required, not to eliminate it entirely.
