The Wallet Transaction Management System is a robust and secure web application built with NestJS, a powerful TypeScript framework for building scalable and efficient server-side applications. This system provides users with a convenient way to manage their digital wallet transactions, ensuring secure money transfers between users while maintaining detailed transaction logs.
- User Authentication: Secure user registration and login system with password hashing.
- Transaction Creation: Users can initiate transactions by providing recipient details, amount, PIN, and OTP verification.
- Transaction Logs: Detailed transaction logs with sender and receiver information, timestamps, and transaction types (sent or received).
- PIN Verification: Transactions require PIN verification for added security.
- Swagger Documentation: API endpoints are documented using Swagger UI for easy testing and integration.
- Database Integration: Utilizes MongoDB for efficient and scalable data storage.
- Authorization and Authentication: Role-based access control ensures only authorized users can access certain features.
The Wallet API uses a MongoDB database with two main collections to store user and transaction data.
The users collection stores user profiles and related information.
The transactions collection stores transaction records between users.pp
The diagram above provides a visual representation of the database schema, illustrating the relationships between the users and transactions collections.
WTMS API is built using Node.js, Express.js and Nest.js, with MongoDB as the database. I'm using the Mongoose library to interact with the database, and JWT for authentication.
Swagger is a powerful tool that generates interactive API documentation, making it easier for developers to understand and interact with your API endpoints. You can access the Swagger documentation for this Wallet API by visiting the following URL:
