api/contracts/contract.go
package contracts
import (
"math/big"
"strings"
)....
func DeployContract(...)
api/contract.go
package main
import (
"api/contracts"
...)
func deployContract(c echo.Context) error {
address, tx, token, err := contracts.DeployContract(auth, client)
...
}
! Best Import is api/go.mod
module api
require (
api/contracts v0.0.0
...)
replace (
api/contracts v0.0.0 => ./contracts
...)
And api/contracts/go.mod
module api/contracts
require (
...)
