SAP CAPM REST API Consumption Tutorial Project

Description

This project was created following a tutorial by Somnath Paul on how to consume REST APIs within SAP Cloud Application Programming Model (CAPM) backend services. The tutorial demonstrates the process using the JSON Placeholder API, a free online REST API for testing purposes.

The project covers:

• Service Definition: Defining function imports and actions in a CAPM service file (todo-task.cds) to interact with the REST API.
• Local Binding: Demonstrating local binding of the REST API within the CAP service for simplicity, suitable for development and learning.
• Backend Logic Implementation: Creating a backend service logic file (todo-task-service.js) to connect to the REST API and implement the logic for retrieving and creating data.
• Testing: Testing the API endpoints using a dedicated test file (test.http) and debugging the CAPM service with VS Code.

This project serves as a practical guide for developers looking to integrate REST APIs into their SAP CAPM applications. It provides a clear and concise example, ideal for learning the fundamentals of REST API consumption in CAPM.

Getting Started

To get started with this project, you will need:

• Node.js and npm installed.
• SAP Cloud Application Programming Model (CAPM) tools installed and configured.
• VS Code (recommended) with relevant extensions for CAPM development.

Installation

1. Clone the repository:

   git clone https://github.com/marksmith-II/cap.rest.api.get

2. Navigate to the project directory:

   cd <project_directory>

3. Install dependencies:

   npm install

Running the Application

1. Start the CAPM service:

   cds watch

2. You can then test the API endpoints using the test.http file in VS Code or any other REST client.

Testing

• Use the test.http file provided in the project to test the API endpoints.
• You can also use tools like Postman or curl to test the API.
• Debug the CAPM service in VS Code by setting breakpoints in the todo-task-service.js file.
