Splitwise Clone API

This Spring Boot project serves as a backend API for a clone of Splitwise, a popular expense management application. The API provides endpoints for managing users, groups, expenses, and settlements, facilitating seamless expense tracking and splitting among users.

Features

• User Management: Allows users to register, login, and manage their profiles.
• Group Management: Enables users to create, join, and manage groups for shared expenses.
• Expense Tracking: Facilitates the creation, editing, and deletion of expenses within groups.

Technologies Used

• Spring Boot: A powerful framework for building Java-based applications, providing a robust development environment.
• Spring Security: Utilized for implementing JWT (JSON Web Token) authentication and authorization.
• Spring Data JPA: Provides a convenient way to access relational databases, simplifying database interactions.
• MySQL: Chosen as the database management system for storing user data, group information, and expenses.
• JSON Web Tokens (JWT): Used for secure authentication by generating tokens for authorized users.

Setup

1. Clone the Repository:

   git clone https://github.com/Satwik-Bhardwaj/SplitwiseAppClone.git

2. Database Configuration:

   • Install MySQL and create a database named Splitwise.
   • Update application.properties with your MySQL username and password:

     spring.datasource.url=jdbc:mysql://localhost:3306/Splitwise
     spring.datasource.username=root
     spring.datasource.password=root

3. OAuth Configuration:

   • Obtain credentials from GCP to enable OAuth functionality.
   • Update application.properties with the following parameters:

     spring.security.oauth2.client.registration.google.client-id=abc123
     spring.security.oauth2.client.registration.google.client-secret=good123

   • If you do not require OAuth2 functionality, you can remove the related parameters and the corresponding controllers and services.

4. Run the Application:

   • Navigate to the project directory.
   • Execute the following command:

     ./mvnw spring-boot:run

Postman Collection

To get started with the API, you can import the Postman collection available on Google Drive:

• Download Postman Collection

Usage

• Authentication: Use the /api/v1/auth/login endpoint to obtain a JWT token by providing valid credentials.
• Endpoints: Utilize the provided endpoints to perform various operations such as user registration, group creation, expense management, etc.
• Authorization: Ensure proper authorization by including the JWT token in the Authorization header for secured endpoints.
