Getting Started

Prerequisites

• Rust (latest stable version)
• MongoDB
• Cargo (Rust package manager) -Vue.js

Installation

1. Clone the repository

git clone [repository-url]

2. Install dependencies

cargo build

3. Configure MongoDB connection

   • Ensure MongoDB is running locally
   • Update connection settings if necessary

4. Run the application

cargo run

The server will start on localhost:8080

Security Notes

• The current password encryption uses a basic Caesar cipher for educational purposes
• For production use, implement a proper cryptographic hashing algorithm
• Ensure proper authentication and authorization mechanisms are in place
• Review and update security measures before deploying to production

Monitoring

The application includes built-in monitoring capabilities:

• CPU usage tracking
• Memory usage monitoring
• Prometheus metrics available at /metrics
