Goth is a web authentication system written in Go. With Goth, you get out-of- the-box user sign in, sign up, and sign out functionality to kick off building your web app.
Not ready for production yet! Use at your own risk. File bugs, pitch in, etc.

The following example mounts goth's authentication handler at /auth/, and
registers a simple handler for the root route that greets the user with the
user's e-mail address if logged in, or as a guest if not.
package main
import (
"fmt"
"net/http"
)
import (
"github.com/jroes/goth"
)
var authHandler = goth.DefaultAuthHandler
func main() {
http.Handle("/auth/", authHandler)
http.HandleFunc("/", helloUserHandler)
// Please use ListenAndServeTLS in production.
http.ListenAndServe(":8080", nil)
}
func helloUserHandler(w http.ResponseWriter, r *http.Request) {
currentUser, ok := authHandler.CurrentUser(r)
if ok {
fmt.Fprintf(w, "Hello, %s!", currentUser.Email)
} else {
fmt.Fprintf(w, "Hello, guest!")
}
}So what does this get you exactly? You get a bunch of routes underneath /auth/:
| HTTP Method | URL | Description |
|---|---|---|
| GET | http://localhost:8080/auth/sign_up | Standard sign up form |
| POST | http://localhost:8080/auth/sign_up | Creates User and persists using the defined UserStore (default: UserGobStore, a store persisted in Go's gob format on disk) |
| GET | http://localhost:8080/auth/sign_in | Standard sign in form |
| POST | http://localhost:8080/auth/sign_in | Creates a session (default: cookie-based through gorilla/sessions) |
| POST | http://localhost:8080/auth/sign_out | Expires the session (default: expires the cookie from gorilla/sessions) |
