Personal Finance App is a modern web application developed as part of a challenge on Frontend Mentor. The app provides an intuitive platform for users to manage their budgets by categorizing expenses as negative and incomes as positive values, ensuring a clear and efficient financial overview.

Key Features

  • Expense and Income Management: Record expenses as negative values and incomes as positive values for easy budget tracking.
  • User-Friendly Interface: Designed to provide a seamless user experience with an intuitive and responsive UI.
  • Secure and Scalable: Built with performance and security in mind, ensuring user data is safe.

Authentication and Security 🔐

  • Access and Refresh Token Management: The application uses JWTs (JSON Web Tokens) for managing user sessions securely.

  • Access Tokens: These are short-lived tokens that are valid for 15 minutes. After expiration, a new access token is generated using the refresh token.

  • Refresh Tokens: These are securely stored in Redis, a fast, in-memory data store, to enhance security and performance. Refresh tokens allow users to stay logged in without needing to re-authenticate frequently.

  • Token Renewal: Access tokens are automatically renewed every 15 minutes using refresh tokens, ensuring a balance between security and usability.

  • This setup ensures a balance between user experience (staying logged in) and security (short-lived access tokens).
