# go-login
[](https://github.com/reddec/go-login)
[](http://godoc.org/github.com/reddec/go-login)
Go handler for login pages with configurable fields.
- Zero-dependencies
- Type-safe configuration (Go generics)
- CSRF protection by-default
- Works well with any HTTP frameworks
- Default minimalistic, mobile-friendly login page
Example
```go
package main
import (
"fmt"
"log"
"net/http"
login "githun.com/reddec/go-login"
)
func loginFunc(writer http.ResponseWriter, r *http.Request, cred login.UserPassword) error {
ok := cred.User == "admin" && cred.Password == "admin" // user proper login and validation
if !ok {
return fmt.Errorf("username or password is incorrect")
}
// use sessions/JWT/cookies and mark following requests as authorized
return nil
}
func main() {
http.HandleFunc("/", func(writer http.ResponseWriter, request *http.Request) {
writer.Write([]byte("
Home
Login"))
})
http.Handle("/login", login.New[login.UserPassword](loginFunc, login.Log(func(err error) {
log.Println(err)
})))
panic(http.ListenAndServe("127.0.0.1:8080", nil))
}
```
## Custom form
Use annotations on string fields:
- `title` for form labels
- `placeholder` for input placeholders
- `hidden` to mark input as hidden (password)
```go
type DomainLogin struct {
Domain string `title:"Domain name" placeholder:"domain or company"`
User string `title:"Username" placeholder:"enter username"`
Password string `title:"Password" placeholder:"enter password" hidden:"true"`
}
```
and handle it as normal
```go
func loginFunc(writer http.ResponseWriter, r *http.Request, cred DomainLogin) error {
// ...
return nil
}
func main() {
// ...
http.Handle("/login", login.New[DomainLogin](loginFunc))
}
```
