Features

• Calculate the area of common shapes: Circle, Rectangle, Triangle, and Square.
• Fast and efficient calculations.
• Formatted response
• Efficient error handling

Prerequisite

Before you begin, ensure you have met the following requirements:

• Go: You need to have Go v1.21+ installed on your machine. Download it from the official Go website.

  To check if Go is installed, run:

  go version

Installation

To get started with the Area Calculator, follow these steps:

1. Clone the repository:

   git clone https://github.com/kunalmemane/AreaCalculator.git
   cd AreaCalculator

2. Build the application:

   go build -o ./bin/main ./cmd/main.go

3. Run the application:

   ./bin/main

The API will be available at http://localhost:8080/

Supported Shapes

• Circle: Requires the radius.
• Rectangle: Requires the length and breadth.
• Triangle: Requires the sideA, sideB and sideC.
• Square: Requires the side length.

Usage

Once the Application is running, you can make HTTP requests to calculate areas of supported shapes using the /getArea endpoint.

Endpoint

POST /getArea

See Demo Request and Expected Responses

Example Request

To calculate the area of multiple shapes, use the following curl command:

• Triangle

  curl -X POST http://localhost:8080/getArea -d '{
          "shape":"Triangle",
          "sideB":20,
          "sideA": 10,
          "sideC":15    
      }' -H "Content-Type: application/json"

Test

• To test the application run below commands

      make test
  
      or
  
      go test ./...
