TL;DR: Replay reconstructs a fully functional Qwik City interactive dashboard directly from a video demonstration, leveraging behavior-driven reconstruction for accurate and efficient code generation.
Rebuilding Interactive UIs: From Video to Qwik City Dashboard#
Building interactive dashboards often involves tedious manual coding, extensive testing, and iterative refinement. What if you could simply show the desired functionality and have the code generated automatically? This is the promise of Replay, a video-to-code engine that leverages Gemini to understand user behavior and reconstruct fully functional UIs. In this article, we'll explore how to use Replay to generate a Qwik City interactive dashboard from a video example.
The Challenge: Traditional UI Development#
Traditional UI development relies heavily on manual coding and visual design tools. This process is time-consuming, error-prone, and often requires significant back-and-forth between designers and developers. Screenshot-to-code tools offer a partial solution, but they lack the crucial ability to understand behavior. They only capture the visual appearance, not the underlying interactions and logic.
⚠️ Warning: Screenshot-to-code tools often fail to capture dynamic behaviors, leading to incomplete or non-functional UI reconstructions.
Introducing Replay: Behavior-Driven Reconstruction#
Replay takes a different approach. Instead of relying on static screenshots, Replay analyzes video recordings of user interactions. This allows it to understand the intended behavior and reconstruct the UI accordingly. This "Behavior-Driven Reconstruction" makes Replay uniquely powerful for generating interactive and dynamic UIs.
| Feature | Screenshot-to-Code | Replay |
|---|---|---|
| Input | Static Images | Video Recordings |
| Behavior Analysis | Limited | Comprehensive |
| Code Accuracy | Lower | Higher |
| Dynamic UI Support | Poor | Excellent |
| Supabase Integration | Often Missing | Built-in |
| Product Flow Mapping | Not Supported | Integrated |
Building a Qwik City Interactive Dashboard with Replay#
Let's walk through the process of generating a Qwik City interactive dashboard using Replay. We'll assume you have a video recording of a working dashboard demonstration.
Step 1: Preparing Your Video#
The quality of your video directly impacts the accuracy of the generated code. Here are some best practices:
- •Clear Visuals: Ensure the video is well-lit and the UI elements are clearly visible.
- •Smooth Interactions: Perform interactions smoothly and deliberately. Avoid rapid mouse movements or erratic clicks.
- •Narrate (Optional): While not required, narrating your actions can provide additional context for Replay's AI engine.
💡 Pro Tip: A short, focused video demonstrating a specific feature or interaction will yield the best results.
Step 2: Uploading to Replay#
- •Log in to your Replay account.
- •Click the "Upload Video" button.
- •Select the video file of your dashboard demonstration.
- •Replay will begin processing the video and analyzing the user interactions.
Step 3: Configuring Replay Settings#
After uploading, you can configure several settings to optimize the code generation:
- •Framework: Select "Qwik City" as the target framework.
- •Styling: Choose your preferred styling approach (e.g., Tailwind CSS, CSS Modules).
- •Data Source: If your dashboard uses a data source, configure the connection details (e.g., Supabase credentials).
Step 4: Generating the Code#
Once the settings are configured, click the "Generate Code" button. Replay will now use its AI engine to reconstruct the Qwik City dashboard based on the video analysis. This process may take a few minutes, depending on the complexity of the dashboard.
Step 5: Reviewing and Refining the Code#
After the code generation is complete, you'll be presented with the reconstructed Qwik City project. Take some time to review the code and make any necessary refinements.
- •Component Structure: Verify that the components are logically organized and named.
- •Event Handlers: Check that event handlers (e.g., button clicks, form submissions) are correctly implemented.
- •Data Binding: Ensure that data is correctly bound to the UI elements.
Example: Interactive Filter Implementation#
Let's say your video demonstrates filtering data in the dashboard. Replay would generate the necessary Qwik City code to handle this interaction. Here's a simplified example of what that code might look like:
typescript// src/components/FilterComponent.tsx import { component$, useSignal, useTask$ } from '@builder.io/qwik'; interface DataItem { id: number; name: string; category: string; } export const FilterComponent = component$(() => { const filterValue = useSignal(''); const data = useSignal<DataItem[]>([ { id: 1, name: 'Product A', category: 'Electronics' }, { id: 2, name: 'Product B', category: 'Clothing' }, { id: 3, name: 'Product C', category: 'Electronics' }, ]); const filteredData = useSignal<DataItem[]>([]); useTask$(({ track }) => { track(filterValue); filteredData.value = data.value.filter(item => item.category.toLowerCase().includes(filterValue.value.toLowerCase()) ); }); return ( <div> <input type="text" placeholder="Filter by category" value={filterValue.value} onInput$={(event) => (filterValue.value = (event.target as HTMLInputElement).value)} /> <ul> {filteredData.value.map(item => ( <li key={item.id}>{item.name} ({item.category})</li> ))} </ul> </div> ); });
This code snippet demonstrates a basic filter component in Qwik City. The

If your dashboard uses Supabase for data storage, Replay can automatically integrate with your Supabase project. You'll need to provide your Supabase URL and API key. Replay will then generate the necessary code to fetch and display data from your Supabase database.
typescript// src/routes/index.tsx import { component$, useClientEffect$, useSignal } from '@builder.io/qwik'; import { createClient } from '@supabase/supabase-js'; const supabaseUrl = 'YOUR_SUPABASE_URL'; const supabaseKey = 'YOUR_SUPABASE_API_KEY'; const supabase = createClient(supabaseUrl, supabaseKey); export default component$(() => { const data = useSignal([]); useClientEffect$(async () => { const { data: products, error } = await supabase .from('products') .select('*'); if (error) { console.error('Error fetching data:', error); } else { data.value = products; } }); return ( <div> <h1>Product List</h1> <ul> {data.value.map((product: any) => ( <li key={product.id}>{product.name}</li> ))} </ul> </div> ); });
This example shows how to fetch data from a Supabase table in a Qwik City route. Replay automates this process, significantly reducing the amount of boilerplate code you need to write.
