How to Fix the \"Import and not used\" Error in Go: Overwriting Package Names and Using Aliases?

Troubleshooting "Import and not used" Error in Go

In Go, the compiler checks for the actual use of imported packages. An "imported and not used" error can occur if a package is imported but not explicitly called within the code.

To resolve this issue, ensure that you utilize something from the imported package. For example:

<code class="go">func main() {
    // import net/http and call methods
    http.Get("example.com")
}</code>

If you do not intend to use the package, remove the import statement.

In your specific case, the error arises because you are overwriting the package name with a variable declaration:

<code class="go">api := ApiResource{map[string]OxiResp{}}</code>

This declares a variable named api instead of using the imported package. To resolve this, rename the variable:

<code class="go">apiResource := ApiResource{map[string]OxiResp{}}</code>

Alternatively, you can alias the package import:

<code class="go">import (
    // Import the package with an alias
    api_package "./api"
)

func main() {
    // Use the aliased name
    api_package.RegisterLogin(restful.NewContainer())
}</code>

Furthermore, it is recommended to import packages using the GOPATH instead of relative paths.
