Solve Dependency Management Problems: Replay AI Creates Package.json Files from Video (2026)

TL;DR: Replay leverages AI to automatically generate

text

package.json

files from video recordings of UI interactions, drastically simplifying dependency management and accelerating development.

Stop manually tracking dependencies! In 2026, you shouldn't be spending hours deciphering which libraries a legacy app uses or meticulously listing every package for a new project. The future of dependency management is here, and it's driven by video.

Traditional methods of dependency management are fraught with problems. From outdated documentation and tribal knowledge to the sheer complexity of modern JavaScript ecosystems, developers face constant hurdles. Replay offers a revolutionary approach: behavior-driven dependency reconstruction directly from video.

The Problem with Traditional Dependency Management#

The pain is real. Think about the last time you inherited a project with a poorly maintained

or, worse, no at all. The process of reverse-engineering dependencies is tedious, error-prone, and a massive time sink. This problem is amplified when dealing with visual frameworks where the UI heavily relies on specific versions of libraries.

Here's why current dependency management falls short:

• •Manual Tracking: Developers are responsible for manually adding, updating, and tracking dependencies. This is prone to errors, especially in large projects.
• •Outdated Documentation: Documentation often lags behind the actual code, leading to incorrect or incomplete dependency information.
• •"Tribal Knowledge": Critical dependency information resides in the heads of senior developers, creating a single point of failure.
• •Version Conflicts: Managing conflicting versions of dependencies can lead to build failures and runtime errors.
• •Security Vulnerabilities: Outdated dependencies often contain security vulnerabilities, making applications susceptible to attacks.

Replay: Behavior-Driven Dependency Reconstruction#

Replay addresses these problems head-on by analyzing video recordings of UI interactions. Instead of relying on static code analysis or manual inspection, Replay understands how the application is used and infers the necessary dependencies based on the observed behavior.

Imagine recording a video of yourself interacting with a complex web application. Replay analyzes that video, identifies the UI components being used, and automatically generates a

file containing all the necessary dependencies, including their correct versions. This is possible because Replay understands the intent behind the UI interactions, not just the pixels on the screen.

Here's how Replay works:

1. •Video Capture: Record a video of the application being used. Focus on demonstrating key features and UI interactions.
2. •AI-Powered Analysis: Replay's AI engine analyzes the video, identifying UI components, network requests, and other relevant information.
3. •Dependency Inference: Based on the analysis, Replay infers the necessary dependencies, including their names and versions.
4. •
   text

   package.json
   Generation: Replay automatically generates a
   text

   package.json
   file containing all the inferred dependencies.
5. •Code Generation: Replay generates React, Vue, or other framework code that matches the video, using the dependencies.

This process, called Behavior-Driven Reconstruction, treats the video as the source of truth, ensuring that the generated

accurately reflects the application's actual dependencies.

Benefits of Replay's Approach#

• •Automated Dependency Management: Eliminates the need for manual tracking and updating of dependencies.
• •Improved Accuracy: Ensures that the
  text

  package.json
  accurately reflects the application's actual dependencies.
• •Reduced Errors: Minimizes the risk of human error associated with manual dependency management.
• •Faster Development: Speeds up the development process by automating dependency management tasks.
• •Enhanced Security: Helps identify and mitigate security vulnerabilities by ensuring that dependencies are up-to-date.
• •Simplified Legacy Code Migration: Makes it easier to migrate legacy applications to modern frameworks by automatically identifying and managing dependencies.

Replay in Action: A Practical Example#

Let's say you have a video of someone interacting with a React application that uses Material UI components and Axios for making API requests. Here's how Replay would generate the

file:

typescript
// Example React component used in the video
import React, { useState, useEffect } from 'react';
import { Button, TextField } from '@mui/material';
import axios from 'axios';

const MyComponent = () => {
  const [data, setData] = useState(null);

  useEffect(() => {
    axios.get('/api/data')
      .then(response => setData(response.data));
  }, []);

  return (
    <div>
      <TextField label="Enter data" />
      <Button variant="contained">Submit</Button>
      {data && <p>Data: {data}</p>}
    </div>
  );
};

export default MyComponent;

After analyzing the video, Replay would generate the following

file:

json
{
  "name": "generated-app",
  "version": "1.0.0",
  "dependencies": {
    "@mui/material": "^5.15.0",
    "@emotion/react": "^11.11.1",
    "@emotion/styled": "^11.11.0",
    "axios": "^1.6.2",
    "react": "^18.2.0",
    "react-dom": "^18.2.0"
  },
  "devDependencies": {
    "@babel/core": "^7.23.6",
    "@babel/preset-env": "^7.23.6",
    "@babel/preset-react": "^7.23.3",
    "babel-loader": "^9.1.3",
    "webpack": "^5.89.0",
    "webpack-cli": "^5.1.4"
  },
  "scripts": {
    "start": "webpack serve --mode development",
    "build": "webpack --mode production"
  }
}

💡 Pro Tip: For best results, ensure the video clearly shows the UI components being used and any network requests being made.

Replay vs. Traditional Methods#

Here's a comparison of Replay with traditional dependency management methods:

Multi-Page Applications and Product Flow Maps#

Replay's capabilities extend beyond single-page applications. It can analyze videos of multi-page applications, automatically identifying dependencies across different pages and generating a comprehensive

file.

Furthermore, Replay can create product flow maps based on the video analysis. These maps visually represent the user's journey through the application, providing valuable insights into user behavior and helping developers understand the application's overall structure.

📝 Note: Replay's product flow maps can be exported as interactive diagrams, making it easy to share and collaborate with other developers.

Step-by-Step Guide to Using Replay for Dependency Management#

Here's a simple guide to get you started with Replay:

Step 1: Capture a Video#

Record a video of yourself interacting with the application. Make sure to demonstrate all the key features and UI components.

Step 2: Upload to Replay#

Upload the video to Replay's platform.

Step 3: Analyze the Video#

Replay will automatically analyze the video and infer the necessary dependencies.

Step 4: Generate the

text

package.json

File#

Replay will generate a

file containing all the inferred dependencies.

Step 5: Download and Integrate#

Download the

file and integrate it into your project.

⚠️ Warning: While Replay strives for accuracy, it's always a good idea to review the generated

text

package.json

file and verify that all dependencies are correctly listed.

Integrating with Supabase#

Replay seamlessly integrates with Supabase, allowing you to automatically generate code that interacts with your Supabase database. This integration simplifies the process of building full-stack applications and ensures that your dependencies are correctly managed.

For example, if your video shows a user submitting a form that saves data to a Supabase table, Replay will automatically generate the necessary code to handle the form submission and save the data, including the correct Supabase client libraries in the

.

typescript
// Example of Supabase integration
import { createClient } from '@supabase/supabase-js'

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

async function insertData(data) {
  const { error } = await supabase
    .from('your_table')
    .insert([ data ])

  if (error) {
    console.error('Error inserting data:', error)
  } else {
    console.log('Data inserted successfully!')
  }
}

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features. Paid plans are available for users who need more advanced capabilities.
