Error: "Imported and Not Used" in Go

When importing a package in Go, an "imported and not used" error occurs if the imported package is not utilized in the current file.

In your case, you have imported the "./api" package. The compiler detects that you have not used this package in your code. To resolve this error, you need to actually utilize something from the package.

You have mentioned that you are using the api package in your main function, but your code is overwriting the imported package with a variable named "api." This is causing a conflict, as the compiler cannot determine whether to use the imported package or the variable.

To fix this issue, you can rename the variable to something else or use an alias for the package import. It's also recommended to import the package via the GOPATH instead of relatively.

Example:

<code class="go">package main

import (
    "fmt"
    "github.com/example/my-api"
)

func main() {
    api.RegisterRoutes()
    fmt.Println("API routes registered")
}</code>

In this example, the "my-api" package is imported and used through the RegisterRoutes function. This eliminates the "imported and not used" error. Remember that if you don't use anything from a package, you should either remove the import or use the "_ import" notation to suppress the error.
