🚀 Installation

Prerequisites

Before you begin, ensure you have the following installed:

• Node.js >= 18.0.0 (Download)
• npm >= 8.0.0 (comes with Node.js)
• Git (Download)
• MetaMask browser extension (for Web3 features) (Install)

Step 1: Clone the Repository

git clone https://github.com/yourusername/autoux.git
cd autoux

Step 2: Install Dependencies

The project uses npm workspaces to manage frontend, backend, and web3 dependencies:

npm install

This single command installs all dependencies for:

• Frontend (React + Vite)
• Backend (Express + Gemini AI)
• Web3 (Hardhat + Ethers.js)

Step 3: Configure Environment Variables

Create environment files for each workspace:

Backend Configuration

cd backend
cp .env.example .env

Edit backend/.env:

# Google Gemini API Configuration
GEMINI_API_KEY=your_gemini_api_key_here

# Server Configuration
PORT=3001
CORS_ORIGIN=http://localhost:5173

Frontend Configuration

cd ../frontend
cp .env.example .env

Edit frontend/.env:

# API Configuration
VITE_API_BASE_URL=http://localhost:3001/api

# Web3 Configuration (after deploying contracts)
VITE_REGISTRY_ADDRESS=0xYOUR_CONTRACT_ADDRESS
VITE_NFT_ADDRESS=0xYOUR_NFT_CONTRACT_ADDRESS
VITE_CHAIN_NAME=Sepolia
VITE_CHAIN_ID=11155111
VITE_ETHERSCAN_URL=https://sepolia.etherscan.io

Web3 Configuration (Optional - for deploying contracts)

cd ../web3
cp .env.example .env

Edit web3/.env:

# Sepolia RPC URL (get from Alchemy or Infura)
SEPOLIA_RPC_URL=https://eth-sepolia.g.alchemy.com/v2/YOUR_API_KEY

# Your wallet private key (NEVER commit this!)
PRIVATE_KEY=0xYOUR_PRIVATE_KEY_HERE

# Etherscan API key (for contract verification)
ETHERSCAN_API_KEY=YOUR_ETHERSCAN_API_KEY

⚠️ Security Warning: Never commit .env files or share private keys!

⚡ Quick Start

Start Development Servers

From the project root, run:

npm run dev

This starts both servers concurrently:

• Backend API: http://localhost:3001
• Frontend UI: http://localhost:5173

The terminal will show color-coded logs for each service.

Alternative: Start Services Individually

# Backend only
npm run dev --prefix backend

# Frontend only
npm run dev --prefix frontend

Your First Analysis

1. Open http://localhost:5173 in your browser
2. Drag and drop a log file (or click to browse)
3. Wait for AI analysis (~5-10 seconds)
4. View your UX score and recommendations!

Try with sample data:

# Use one of the test files
# Upload: test-data/1-logs-complet.json

🔗 Web3 Setup

AutoUX supports blockchain-based verification of AI-generated reports using Ethereum smart contracts. This provides immutable proof that a report hasn't been tampered with, while keeping your logs completely private.

Why Web3?

• ✅ Immutable Proof - Reports can't be altered without detection
• ✅ Privacy-Preserved - Only SHA-256 hashes stored on-chain, logs stay local
• ✅ Public Verification - Anyone can verify report authenticity
• ✅ Audit Trail - Includes uploader address and timestamp
• ✅ Decentralized - No central authority required

Prerequisites

1. MetaMask Browser Extension

   • Install from https://metamask.io/
   • Create a wallet or import existing one

2. Sepolia Testnet ETH

   • Get free testnet ETH from faucets:
     • https://sepoliafaucet.com/
     • https://www.alchemy.com/faucets/ethereum-sepolia
   • You'll need ~0.01 ETH for gas fees

3. RPC Provider (for contract deployment)

   • Create free account at Alchemy or Infura
   • Get Sepolia RPC URL

Step-by-Step Setup

1. Deploy Smart Contract

cd web3
npm install
cp .env.example .env

Edit web3/.env:

SEPOLIA_RPC_URL=https://eth-sepolia.g.alchemy.com/v2/YOUR_API_KEY
PRIVATE_KEY=0xYOUR_PRIVATE_KEY_HERE

Deploy the contract:

npm run deploy:sepolia

Expected output:

🚀 Deploying AutoUXRegistry to Sepolia...
✅ AutoUXRegistry deployed to: 0x1234567890abcdef...

2. Configure Frontend

Copy the deployed contract address and update frontend/.env:

VITE_REGISTRY_ADDRESS=0x1234567890abcdef...
VITE_CHAIN_NAME=Sepolia
VITE_CHAIN_ID=11155111
VITE_ETHERSCAN_URL=https://sepolia.etherscan.io

3. Configure MetaMask

1. Open MetaMask
2. Click network dropdown → "Add Network"
3. Select "Sepolia Test Network"
4. Get testnet ETH from faucet (link above)

4. Use Web3 Features

1. Start the application: npm run dev
2. Upload logs and generate a report
3. Scroll to "On-Chain Proof" section
4. Click "Connect Wallet" → Approve in MetaMask
5. Click "📌 Anchor Hash" → Confirm transaction
6. Wait ~15 seconds for confirmation
7. Click "🔍 Verify Hash" to verify authenticity

Smart Contract Details

AutoUXRegistry.sol - Main contract for hash storage

// Store a report hash
function storeHash(string reportId, bytes32 contentHash) external

// Verify a report hash
function verifyHash(string reportId, bytes32 contentHash) external view returns (bool)

// Get stored record
function getRecord(string reportId) external view returns (bytes32, address, uint64)

Network: Ethereum Sepolia Testnet
Chain ID: 11155111
Gas Cost: 50,000 gas ($0.10 on testnet)
Hash Algorithm: SHA-256 (32 bytes)

Optional: NFT Badges

Deploy the NFT contract to mint badges for verified reports:

cd web3
npm run deploy:nft

Update frontend/.env:

VITE_NFT_ADDRESS=0xYOUR_NFT_CONTRACT_ADDRESS

Users can then mint ERC-721 NFT badges with their UX score and report hash.

    <id>log-001</id>
    <timestamp>2025-11-14T10:30:00Z</timestamp>
    <type>performance</type>
    <message>High response time</message>
    <metadata>
      <responseTime>4500</responseTime>
    </metadata>
  </log>
</logs>

5. HTML (.html)

HTML tables containing log data.

Example:

<table>
  <tr>
    <th>ID</th><th>Timestamp</th><th>Type</th><th>Message</th>
  </tr>
  <tr>
    <td>log-001</td>
    <td>2025-11-14T10:30:00Z</td>
    <td>performance</td>
    <td>High response time</td>
  </tr>
</table>

6. HAR (.har)

HTTP Archive format (browser network logs).

Example:

{
  "log": {
    "version": "1.2",
    "entries": [
      {
        "startedDateTime": "2025-11-14T10:30:00Z",
        "time": 4500,
        "request": {
          "method": "GET",
          "url": "https://api.example.com/data"
        },
        "response": {
          "status": 200
        }
      }
    ]
  }
}

7. Plain Text (.txt, .log)

Unstructured text logs (parsed line by line).

Example:

[2025-11-14 10:30:00] ERROR: Image missing alt text on /home
[2025-11-14 10:31:00] WARN: API response time 4500ms exceeds threshold
[2025-11-14 10:32:00] ERROR: JavaScript TypeError in main.js:42

Detection Logic

The parser automatically detects format using:

1. File extension (.json, .csv, .xml, etc.)
2. Content inspection (JSON structure, CSV headers, XML tags)
3. Fallback to plain text parsing

Sample Files

Test files are available in test-data/:

File	Description	Expected Issues
1-logs-complet.json	Complete test (all types)	7 issues
2-logs-latence.json	Latency tests	4 issues
