Replay AI for Vue.js 3: Building Dynamic Forms in Record Time

TL;DR: Ditch static form builders and embrace Replay AI to generate fully functional Vue.js 3 forms directly from video recordings, enabling rapid prototyping and iteration.

Stop manually coding forms. Seriously. In the age of AI-powered code generation, spending hours wrestling with Vue.js form components is an antiquated practice. The problem? Existing "AI" solutions often rely on static screenshots, resulting in brittle, incomplete code. They capture the appearance of the form, but not the behavior.

Replay AI: Behavior-Driven Form Generation for Vue.js 3#

Replay offers a fundamentally different approach: behavior-driven reconstruction. Instead of analyzing static images, Replay analyzes video recordings of user interactions. This unlocks a deeper understanding of form logic, validation rules, and dynamic behavior, leading to more complete and robust Vue.js code.

Replay uses Gemini to meticulously reconstruct working UI from screen recordings. We call it Behavior-Driven Reconstruction - because the video IS the source of truth.

Here's why it matters:

• •Speed: Generate complex forms in minutes, not hours.
• •Accuracy: Reconstruct behavior, not just appearance.
• •Iteration: Easily modify and refine forms based on real user flows.

Let's dive into how Replay empowers Vue.js 3 developers to build dynamic forms in record time.

Why Video Matters: Understanding User Intent#

Screenshot-to-code tools are inherently limited. They can identify UI elements, but they can't infer why a user is interacting with them. Replay, on the other hand, leverages video to capture the full context of user behavior.

Consider a simple example: a registration form with conditional fields. If a user selects "Business" as their account type, additional fields for company name and size appear. A screenshot-to-code tool would only see the final state of the form, making it difficult to implement the conditional logic. Replay, by analyzing the video, understands the sequence of actions and can accurately reconstruct the conditional rendering in Vue.js.

Building a Dynamic Vue.js 3 Form with Replay#

Let's walk through a practical example: building a dynamic contact form with conditional fields. We'll use Replay to generate the initial Vue.js code and then refine it to meet specific requirements.

Step 1: Recording the Form Interaction#

First, record a video of yourself interacting with a similar form. This video should demonstrate all possible scenarios, including:

• •Filling out all required fields.
• •Triggering validation errors.
• •Activating conditional fields.

The clearer and more comprehensive the recording, the better the resulting code.

💡 Pro Tip: Speak clearly and deliberately during the recording. This helps Replay understand your intent. For example, say "I'm selecting 'Business' account type" before making the selection.

Step 2: Uploading and Processing the Video#

Upload the video to Replay. Replay's AI engine will analyze the video and generate Vue.js 3 code, including:

• •Form structure (input fields, labels, buttons).
• •Data binding (using
  text

  v-model
  ).
• •Validation rules (using a library like VeeValidate or native HTML5 validation).
• •Conditional rendering (using
  text

  v-if
  or
  text

  v-show
  ).
• •Basic styling.

Step 3: Refining the Generated Code#

The generated code will serve as a solid foundation. You can then refine it to meet your specific needs. Here's an example of the initial code Replay might generate:

vue
<template>
  <form @submit.prevent="handleSubmit">
    <div>
      <label for="name">Name:</label>
      <input type="text" id="name" v-model="form.name" required>
    </div>
    <div>
      <label for="email">Email:</label>
      <input type="email" id="email" v-model="form.email" required>
    </div>
    <div>
      <label for="accountType">Account Type:</label>
      <select id="accountType" v-model="form.accountType">
        <option value="personal">Personal</option>
        <option value="business">Business</option>
      </select>
    </div>
    <div v-if="form.accountType === 'business'">
      <label for="companyName">Company Name:</label>
      <input type="text" id="companyName" v-model="form.companyName" required>
    </div>
    <button type="submit">Submit</button>
  </form>
</template>

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

export default {
  setup() {
    const form = ref({
      name: '',
      email: '',
      accountType: 'personal',
      companyName: ''
    });

    const handleSubmit = () => {
      console.log('Form submitted:', form.value);
      // Add your submission logic here
    };

    return {
      form,
      handleSubmit
    };
  }
};
</script>

This code provides a basic, functional form with conditional rendering for the "Company Name" field.

Step 4: Adding Advanced Features (Example: Supabase Integration)#

Replay also simplifies integrating with backend services. Let's say you want to save form submissions to a Supabase database. You can easily add this functionality to the generated code:

typescript
// Assuming you have a Supabase client initialized
import { createClient } from '@supabase/supabase-js';
import { ref } from 'vue';

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

export default {
  setup() {
    const form = ref({
      name: '',
      email: '',
      accountType: 'personal',
      companyName: ''
    });

    const handleSubmit = async () => {
      console.log('Form submitted:', form.value);

      const { data, error } = await supabase
        .from('contacts') // Replace 'contacts' with your table name
        .insert([form.value]);

      if (error) {
        console.error('Error inserting data:', error);
      } else {
        console.log('Data inserted successfully:', data);
        // Optionally, reset the form
        form.value = {
          name: '',
          email: '',
          accountType: 'personal',
          companyName: ''
        };
      }
    };

    return {
      form,
      handleSubmit
    };
  }
};

This code snippet demonstrates how to connect to Supabase and insert form data into a database table. Replay can even generate the initial Supabase integration code if it detects database interactions in the video.

📝 Note: Remember to replace

text

YOUR_SUPABASE_URL

and

text

YOUR_SUPABASE_ANON_KEY

with your actual Supabase credentials.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited usage. Paid plans are available for more advanced features and higher usage limits. Check the Replay pricing page for details.

How is Replay different from v0.dev?#

While both are AI-powered code generation tools, Replay distinguishes itself by analyzing video recordings instead of static screenshots. This enables Replay to understand user behavior and generate more complete, robust, and dynamic code. V0.dev is fantastic for quick UI mockups, but Replay excels at generating functional, behavior-driven applications.

Can Replay handle complex form validation?#

Yes! Replay can detect and reconstruct various form validation techniques, including required fields, email validation, and custom validation rules. The generated code will often include appropriate validation logic using libraries like VeeValidate or native HTML5 validation.

What Vue.js component libraries does Replay support?#

Replay works well with most standard Vue.js component libraries, including Vuetify, Element Plus, and Ant Design Vue. While it's not explicitly tied to any single library, Replay's generated code often leverages common component patterns that are easily adaptable to different libraries.
