Server-Side Calculator

This Express.js server acts as a calculator API, providing basic arithmetic operations such as addition, subtraction, multiplication, and division. The server exposes a RESTful API endpoint that accepts POST requests containing the operation and two numbers. It calculates the result based on the provided operation and returns the result in the response.

Usage

To use the calculator, make a POST request to the /calculate endpoint with a JSON object containing the following properties:

  • operation: A string representing the operation to perform ('add', 'subtract', 'multiply', or 'divide').
  • num1: The first number for the operation.
  • num2: The second number for the operation.

The API will calculate the result based on the provided operation and numbers and respond with a JSON object containing the calculated result.

  • Method: POST
  • Request Body: JSON object with operation (string: 'add', 'subtract', 'multiply', or 'divide'), num1 (number), and num2 (number).
  • Response: JSON object with the calculated result.

    "num1": 7,
    "num2": 3
}
