• User Management: Create, update, and delete user accounts.
• Account Management: Add, view, and manage bank accounts for users.
• Transaction Handling: Record and manage transactions between accounts.
• Security: Protect sensitive data with encryption and authentication.

Before setting up the Bank Backend, ensure you have the following prerequisites installed:

• Go Lang: Go programming language.
• PostgreSQL: PostgreSQL database server.
• Git: Version control tool.

1. Clone this repository:

   git clone https://github.com/kingsleyocran/go-bank-backend.git
   cd bank-backend

2. Create a PostgreSQL database for the application. You can use the PostgreSQL command line or a GUI tool like pgAdmin to create a database and user with appropriate privileges.

3. Set up environment variables. Create a .env file in the root directory with the following content:

DB_DRIVER=postgres DB_SOURCE=postgresql://root:secret@localhost:5432/simple_bank?sslmode=disable SERVER_ADDRESS=0.0.0.0:8080

Replace the placeholders with your database and secret key information.

4. Install required Go packages:

```bash
go mod tidy

1. Start the application:

   go run main.go

   The server should now be running at http://localhost:8080.

2. Access the API endpoints using an API client like Postman or curl. Refer to the API documentation for available endpoints and request formats.

The Bank Backend provides a comprehensive API for managing user accounts, bank accounts, and transactions. You can access the API documentation by navigating to http://localhost:8080/swagger/index.html when the application is running.

• main.go: Application entry point.
• db: Database interaction logic, models and schemas.
• api: API routes and middleware.
• utils: Utility functions and helper methods.

Contributions to this project are welcome. Feel free to open issues and pull requests to help improve the Bank Backend.
