Created a CRUD Operation code using go lang!

1.Data Model: Defined within the same file using the Item struct. 2.In-Memory Store: Uses a global map and a mutex for concurrent access. 3.Handlers:

• createItem: Adds a new item.
• readItem: Retrieves an item by ID.
• updateItem: Updates an existing item.
• deleteItem: Deletes an item. 4.Routing: Uses gorilla/mux to handle HTTP routes and methods. 5.Server Setup: Starts an HTTP server on port 8080.

Structure of the directory:

  /your-project-directory
|-- main.go
|-- go.mod
|-- go.sum

You can then use tools like curl to check the CRUD operation

• Create

  curl -X POST http://localhost:8080/items -d '{"id":"1","name":"Item 1"}' -H "Content-Type: application/json"

• Read

  curl http://localhost:8080/items/1

• Update

curl -X PUT http://localhost:8080/items/1 -d '{"id":"1","name":"Updated Item"}' -H "Content-Type: application/json"

• Delete

  curl -X DELETE http://localhost:8080/items/1
