⚙️ Setup Guide

Prerequisites

• GitHub Account with repository access
• LeetCode Account
• Python 3.10 or higher
• Git CLI

Detailed Configuration Steps

1. Repository Setup

   # Clone the repository
   git clone https://github.com/thetoriqul/leetcode-solutions.git
   cd leetcode-solutions
   
   # Install dependencies
   pip install -r requirements.txt

2. Environment Configuration

   # Create .env file
   cp .env.example .env
   
   # Add your configuration
   GH_PAT=your_github_token
   LEETCODE_SESSION=your_leetcode_session (Remeber, you have to regularly monitor the credentials)
   GITHUB_REPO=thetoriqul/leetcode-solutions

3. GitHub Secret Configuration

   Navigate to: Settings > Secrets and Variables > Actions

   Required Secrets:

   GH_PAT: your_github_personal_access_token
   LEETCODE_SESSION: your_leetcode_session_cookie (Remeber, you have to regularly monitor the credentials)

4. GitHub Personal Access Token Setup

   • Visit: Settings > Developer settings > Personal access tokens > Tokens (classic)
   • Required Scopes:

     - repo (Full control of private repositories)
     - workflow (Update GitHub Action workflows)
     - admin:org (Optional: For organization-level access)
     

5. LeetCode Session Token Retrieval

   // Browser DevTools (F12) -> Console
   document.cookie.split(';').find(cookie => 
     cookie.includes('LEETCODE_SESSION')
   ).split('=')[1]

🎯 Usage

Automatic Synchronization

Solutions are automatically synchronized at midnight (00:00) on the first day of every month.

Manual Synchronization

1. Visit the Actions tab
2. Select "Sync LeetCode Solutions"
3. Click "Run workflow"
4. Select branch (default: main)
5. Trigger the workflow

Custom Synchronization

# Run sync script locally
python scripts/sync_leetcode.py --days 7  # Sync last 7 days
python scripts/sync_leetcode.py --all     # Sync all solutions
