How to Recreate a Job Board App from Video to React with Supabase and Replay (2026)

TL;DR: Learn how to reconstruct a fully functional job board application from a simple screen recording using Replay, React, and Supabase, leveraging behavior-driven code generation.

The future of UI development isn't about pixel-perfect mockups; it's about capturing user intent and translating it into working code. Screenshot-to-code tools fall short because they only see the surface. We need tools that understand behavior. That's where Replay comes in. Forget static images; we're talking about video.

Recreating a Job Board App: The Video-to-Code Revolution#

Imagine recording a quick demo of your dream job board app – sketching out the user flow, interactions, and desired functionality. Now, imagine turning that video into a fully functional React application with Supabase integration, complete with styling and data persistence. Sounds like science fiction? It's not. It's Replay.

This guide will walk you through the process of recreating a job board application from a video recording using Replay, React, and Supabase. We'll cover everything from setting up your environment to deploying your final product.

Why Video-to-Code?#

Traditional UI development often involves:

• •Lengthy design phases
• •Back-and-forth communication with designers
• •Manual coding of UI components
• •Tedious testing and debugging

Video-to-code offers a radically different approach. By analyzing video recordings of user interactions, Replay can automatically generate working code, significantly reducing development time and effort. This allows developers to focus on higher-level logic and features, rather than getting bogged down in UI implementation details.

Setting Up Your Development Environment#

Before we dive into the video-to-code process, let's set up our development environment. You'll need:

1. •Node.js and npm (or yarn): Ensure you have Node.js and npm (or yarn) installed on your machine. You can download them from the official Node.js website.
2. •A code editor: Choose your favorite code editor (e.g., VS Code, Sublime Text, Atom).
3. •A Supabase account: Sign up for a free Supabase account at supabase.com.
4. •Replay Account: Create an account at replay.build

Step 1: Creating a React Project#

We'll start by creating a new React project using Create React App:

bash
npx create-react-app job-board-app
cd job-board-app

This command sets up a basic React project with all the necessary dependencies.

Step 2: Installing Dependencies#

Next, we'll install the necessary dependencies for our job board application:

bash
npm install @supabase/supabase-js react-router-dom styled-components

Here's a breakdown of these dependencies:

• •
  text

  @supabase/supabase-js
  : The official Supabase JavaScript client for interacting with our database.
• •
  text

  react-router-dom
  : For handling navigation between different pages in our application.
• •
  text

  styled-components
  : For styling our React components with CSS-in-JS.

Step 3: Setting Up Supabase#

1. •Log in to your Supabase account.
2. •Create a new project.
3. •Once the project is created, navigate to the "SQL Editor" and create a table named
   text

   jobs
   with the following schema:

sql
create table jobs (
  id uuid primary key default uuid_generate_v4(),
  title text,
  company text,
  description text,
  location text,
  salary integer,
  created_at timestamp with time zone default timezone('utc'::text, now())
);

1. •Go to "Settings" -> "API" to find your Supabase URL and API key. You'll need these later.

📝 Note: Ensure you have

text

uuid-ossp

extension enabled in your Supabase project. This is required for generating UUIDs for your job postings.

Capturing the Video Demo#

Now for the fun part! Record a video demo of your ideal job board app. This video should showcase:

• •The home page with a list of job postings.
• •The job details page.
• •The process of creating a new job posting (if applicable).
• •Any other relevant interactions or features.

💡 Pro Tip: Speak clearly and deliberately during the recording, highlighting the key elements and actions you want Replay to capture. The more detail you provide, the better the generated code will be.

Using Replay to Generate Code#

With your video demo ready, it's time to unleash the power of Replay.

Step 1: Uploading the Video#

1. •Log in to your Replay account at replay.build.
2. •Click the "Upload Video" button and select your video file.

Step 2: Configuring Replay#

Once the video is uploaded, Replay will analyze it and present you with configuration options. Here are some key settings to consider:

• •Framework: Select "React" as the target framework.
• •Styling: Choose "Styled Components" to match our project setup.
• •Data Integration: Select "Supabase" and provide your Supabase URL and API key.
• •Multi-Page Generation: Ensure this is enabled to correctly generate components for each page in the video.

Step 3: Generating the Code#

Click the "Generate Code" button and let Replay work its magic. The process may take a few minutes, depending on the length and complexity of your video.

Replay uses advanced AI algorithms to analyze the video, identify UI elements, understand user interactions, and generate clean, maintainable React code. It even infers the data structure for your Supabase database based on the video content.

⚠️ Warning: The generated code may not be perfect on the first try. You may need to make some manual adjustments to fine-tune the functionality and styling.

Step 4: Integrating the Generated Code#

Once the code generation is complete, Replay will provide you with a zip file containing the generated React components, styles, and Supabase integration code.

1. •Extract the contents of the zip file into your
   text

   src
   directory of your React project.
2. •Update your
   text

   App.js
   file to include the generated components and routing configuration.

Here's an example of how to integrate the generated components into your

file:

typescript
// App.js
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import JobList from './components/JobList'; // Generated by Replay
import JobDetails from './components/JobDetails'; // Generated by Replay
import CreateJob from './components/CreateJob'; // Generated by Replay
import SupabaseProvider from './SupabaseProvider'; // Assuming Replay generates a provider

function App() {
  return (
    <SupabaseProvider>
      <Router>
        <Switch>
          <Route exact path="/" component={JobList} />
          <Route path="/jobs/:id" component={JobDetails} />
          <Route path="/create" component={CreateJob} />
        </Switch>
      </Router>
    </SupabaseProvider>
  );
}

export default App;

Refining and Customizing the Generated Code#

While Replay generates a solid foundation for your job board application, you'll likely want to refine and customize the code to meet your specific requirements.

Data Fetching and Management#

Replay will generate basic data fetching logic using the Supabase client. You can customize this logic to add filtering, sorting, and pagination.

Here's an example of how to fetch job postings from Supabase in the

component:

typescript
// JobList.js
import React, { useState, useEffect } from 'react';
import { supabase } from '../supabaseClient'; // Assuming Replay creates this

const JobList = () => {
  const [jobs, setJobs] = useState([]);

  useEffect(() => {
    const fetchJobs = async () => {
      const { data, error } = await supabase
        .from('jobs')
        .select('*')
        .order('created_at', { ascending: false });

      if (error) {
        console.error('Error fetching jobs:', error);
      } else {
        setJobs(data);
      }
    };

    fetchJobs();
  }, []);

  return (
    <div>
      {jobs.map((job) => (
        <div key={job.id}>
          <h3>{job.title}</h3>
          <p>{job.company}</p>
          <p>{job.location}</p>
        </div>
      ))}
    </div>
  );
};

export default JobList;

Styling and UI Enhancements#

Replay uses Styled Components to style the generated UI. You can customize the styles by modifying the Styled Components definitions in each component file.

For example, you can change the background color and font size of the

component by modifying its Styled Components:

typescript
// JobList.js
import styled from 'styled-components';

const JobListContainer = styled.div`
  background-color: #f0f0f0;
  padding: 20px;
`;

const JobTitle = styled.h3`
  font-size: 24px;
  color: #333;
`;

const JobList = () => {
  // ... (rest of the component code)

  return (
    <JobListContainer>
      {jobs.map((job) => (
        <div key={job.id}>
          <JobTitle>{job.title}</JobTitle>
          <p>{job.company}</p>
          <p>{job.location}</p>
        </div>
      ))}
    </JobListContainer>
  );
};

export default JobList;

Adding New Features#

Replay provides a solid foundation for your application, but you may want to add new features that weren't included in the original video demo. You can easily add new components, routes, and functionality using standard React development techniques.

Comparison: Replay vs. Traditional Methods#

Let's compare Replay with traditional UI development methods:

📝 Note: Screenshot-to-code tools are limited by the static nature of screenshots. Replay's video analysis allows it to capture user behavior and generate more complete and functional code.

Addressing Common Concerns#

Code Quality#

One common concern is the quality of the generated code. Replay strives to generate clean, maintainable code, but it may not always be perfect. You may need to refactor and optimize the code to meet your specific standards.

Accuracy#

The accuracy of the generated code depends on the quality of the video demo. Clear, well-defined videos will result in more accurate code.

Customization#

While Replay automates much of the UI development process, it doesn't eliminate the need for customization. You'll still need to refine the code and add new features to create a fully functional application.

Deploying Your Job Board App#

Once you're satisfied with your job board application, you can deploy it to a hosting platform like Netlify, Vercel, or Firebase Hosting. These platforms offer easy deployment options for React applications.

Here's an example of how to deploy your application to Netlify:

1. •Create a Netlify account and install the Netlify CLI:

bash
npm install -g netlify-cli

1. •Build your React application:

bash
npm run build

1. •Deploy your application to Netlify:

bash
netlify deploy --prod

This command will deploy your application to Netlify and provide you with a live URL.

Frequently Asked Questions#
