# Required [](https://travis-ci.org/tiaguinho/required) [](https://godoc.org/github.com/tiaguinho/required) [](https://goreportcard.com/report/github.com/tiaguinho/required) [](https://codecov.io/gh/tiaguinho/required)
Required is used to validate if the field value is empty
### Install
```bash
go get github.com/tiaguinho/required
```
### Example
Simplest way to use the package:
```go
package main
import (
"github.com/tiaguinho/required"
"log"
)
type Test struct {
FirstName string `json:"first_name" required:"-"`
LastName string `json:"last_name" required:"last name is required"`
}
func main() {
t := Test{
FirstName: "Go",
LastName: "Required",
}
if err := required.Validate(t); err != nil {
log.Println(err)
}
}
```
If you like to get all the validation messages with field's name to return in some API, just change to this:
```go
func main() {
t := Test{
FirstName: "Go",
LastName: "Required",
}
if msg, err := required.ValidateWithMessage(t); err != nil {
log.Println(err, msg)
}
}
```
