Vue.js 3 Component Library from Video Walkthroughs

TL;DR: Replay enables rapid creation of Vue.js 3 component libraries directly from video walkthroughs, leveraging AI-powered behavior analysis for accurate and functional code generation.

Manually building a component library is tedious. Watching hours of tutorial videos, pausing, copying, and adapting code is a massive time sink. What if you could simply show an AI how you want your components to behave, and it generates the code for you? That's the power of behavior-driven reconstruction, and it's now a reality for Vue.js 3 developers.

The Problem: Manual Component Creation is a Grind#

Building a Vue.js 3 component library from scratch often involves:

• •Scouring the internet for design inspiration and tutorials.
• •Painstakingly transcribing code from video walkthroughs.
• •Debugging inconsistencies and adapting code to your specific project.
• •Manually handling styling and ensuring responsiveness.
• •Dealing with the inevitable drift between the intended design and the final implementation.

This process is slow, error-prone, and frankly, soul-crushing. Screenshot-to-code tools offer limited assistance, as they lack the crucial understanding of user intent and dynamic behavior. They can only reproduce what they see, not what the user does.

The Solution: Behavior-Driven Reconstruction with Replay#

Replay is a video-to-code engine that uses Gemini to reconstruct working UI from screen recordings. It analyzes the behavior demonstrated in the video, not just the static visuals. This "Behavior-Driven Reconstruction" allows Replay to generate Vue.js 3 components that are not only visually accurate but also functionally correct.

Key Features for Vue.js 3 Component Libraries#

Replay offers several features that are particularly beneficial for creating Vue.js 3 component libraries:

• •Multi-Page Generation: Replay can handle complex flows that span multiple pages, ensuring your components work seamlessly within a larger application.
• •Supabase Integration: Easily connect your generated components to a Supabase backend for data management and persistence.
• •Style Injection: Replay intelligently injects styles, allowing you to customize the appearance of your components with ease.
• •Product Flow Maps: Visualize the user flow within your video, providing a clear understanding of how different components interact.

How Replay Differs from Screenshot-to-Code Tools#

The key difference lies in the understanding of user behavior. Screenshot-to-code tools are limited to visual analysis, while Replay analyzes the actions performed in the video.

💡 Pro Tip: When recording your video, clearly demonstrate the different states and interactions of your component. The more information Replay has, the better the generated code will be.

Creating a Vue.js 3 Component Library: A Step-by-Step Guide#

Let's walk through the process of creating a simple Vue.js 3 component library using Replay. In this example, we'll create a custom button component.

Step 1: Record a Video Walkthrough#

Record a video demonstrating the desired behavior of your button component. This should include:

• •The initial state of the button.
• •The hover state.
• •The active (clicked) state.
• •Any loading or disabled states.
• •Different color variations (e.g., primary, secondary, danger).
• •Different size variations (e.g., small, medium, large).

⚠️ Warning: Ensure your video is clear and well-lit. Avoid excessive mouse movements or distractions. Focus on demonstrating the core behavior of the component.

Step 2: Upload the Video to Replay#

Upload your video to the Replay platform. Replay will automatically analyze the video and generate the corresponding Vue.js 3 component code.

Step 3: Review and Refine the Generated Code#

Replay provides a code editor where you can review and refine the generated code.

vue
<template>
  <button
    class="custom-button"
    :class="{
      'custom-button--primary': primary,
      'custom-button--secondary': secondary,
      'custom-button--danger': danger,
      'custom-button--small': small,
      'custom-button--medium': medium,
      'custom-button--large': large,
      'custom-button--loading': loading,
      'custom-button--disabled': disabled,
    }"
    :disabled="disabled"
    @click="handleClick"
  >
    <span v-if="loading">Loading...</span>
    <span v-else><slot /></span>
  </button>
</template>

<script setup>
import { defineProps, defineEmits } from 'vue';

const props = defineProps({
  primary: { type: Boolean, default: false },
  secondary: { type: Boolean, default: false },
  danger: { type: Boolean, default: false },
  small: { type: Boolean, default: false },
  medium: { type: Boolean, default: true },
  large: { type: Boolean, default: false },
  loading: { type: Boolean, default: false },
  disabled: { type: Boolean, default: false },
});

const emit = defineEmits(['click']);

const handleClick = () => {
  if (!props.disabled && !props.loading) {
    emit('click');
  }
};
</script>

<style scoped>
.custom-button {
  /* Base styles */
  padding: 10px 20px;
  border: none;
  border-radius: 5px;
  cursor: pointer;
  font-size: 16px;
  transition: background-color 0.3s ease;
}

.custom-button--primary {
  background-color: #007bff;
  color: white;
}

.custom-button--secondary {
  background-color: #6c757d;
  color: white;
}

.custom-button--danger {
  background-color: #dc3545;
  color: white;
}

.custom-button--small {
  padding: 5px 10px;
  font-size: 12px;
}

.custom-button--medium {
  padding: 10px 20px;
  font-size: 16px;
}

.custom-button--large {
  padding: 15px 30px;
  font-size: 20px;
}

.custom-button--loading {
  cursor: not-allowed;
  opacity: 0.7;
}

.custom-button--disabled {
  cursor: not-allowed;
  opacity: 0.5;
}

.custom-button:hover:not(:disabled):not(.custom-button--loading) {
  opacity: 0.8;
}

.custom-button:active:not(:disabled):not(.custom-button--loading) {
  opacity: 0.6;
}
</style>

Step 4: Integrate the Component into Your Library#

Copy the generated code into your Vue.js 3 component library. You can then import and use the component in your projects.

typescript
// Example usage in another component
<template>
  <CustomButton primary @click="handleClick">Click Me</CustomButton>
</template>

<script setup>
import CustomButton from './components/CustomButton.vue';

const handleClick = () => {
  alert('Button clicked!');
};
</script>

📝 Note: Replay is constantly learning and improving. The more you use it, the better it will become at generating accurate and functional code.

Benefits of Using Replay for Component Library Creation#

• •Significant Time Savings: Reduce development time by automating the code generation process.
• •Improved Accuracy: Behavior-driven reconstruction ensures that the generated components behave as intended.
• •Reduced Errors: Minimize manual transcription errors and inconsistencies.
• •Enhanced Collaboration: Easily share video walkthroughs with your team and generate code collaboratively.

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 advanced features.

How is Replay different from v0.dev?#

While both tools aim to generate code, Replay focuses on video as the primary input and utilizes behavior analysis to understand user intent. v0.dev typically relies on text prompts and may not capture the nuances of dynamic UI behavior as effectively. Replay is designed to understand what the user is trying to accomplish, not just what they describe.

What frameworks are supported?#

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

What types of videos work best with Replay?#

Videos that clearly demonstrate the desired behavior of the UI elements work best. Ensure the video is well-lit, stable, and free from distractions. Focus on showcasing the different states and interactions of the component.

Can I customize the generated code?#

Yes, Replay provides a code editor where you can review and refine the generated code. You can also integrate the generated code into your existing codebase and customize it further.
