You are probably using goimports
(by default, behind the scenes) to rewrite imports on save. It helpfully adds imports you lack and removes imports you don’t need. So, don’t add an import - add an import and something that uses it, or just something that uses it and the import will be added automatically.
Thanks Jakob
Also note that
It is an error to import a package […] without using it.
There are cases where you want to import a package without directly using it. An example for this is a library that implements database/sql
. If you want to use SQLite you would do something like this:
import (
"database/sql"
_ "github.com/mattn/go-sqlite3"
)
This will make everything provided by the sql
package available. The blank indentifier _
used for the SQLite package allows you to import this package without using it directly.
To silence complaints about the unused imports, use a blank identifier to refer to a symbol from the imported package.
