Os or Go Server

A minimal Go HTTP server that exposes a small in-memory products API. It ships with a few seeded products, supports creating new ones, and can fetch products by ID.

Requirements

• Go 1.22+
• Standard library only

Run

go run main.go

The server starts on http://localhost:8081.

API

Health check

GET /test

curl http://localhost:8081/test

List products

GET /products

Returns the current in-memory product list as JSON.

curl http://localhost:8081/products

Get a product by ID

GET /products/{id}

curl http://localhost:8081/products/1

Create a product

POST /products

Request body (JSON):

{
	"title": "Product name",
	"description": "Short description",
	"price": 19.99,
	"image_url": "https://example.com/image.jpg"
}

curl -X POST http://localhost:8081/products \
	-H "Content-Type: application/json" \
	-d '{"title":"Product name","description":"Short description","price":19.99,"image_url":"https://example.com/image.jpg"}'

Notes:

• The server assigns the id field automatically.
• Data is stored in memory, so restarting the server resets the product list.
• Make sure the Content-Type header is application/json.
