Sign in

The sign in flow follows the same pattern as the sign up flow but instead of redirecting to the registration page, it redirects to the login page.

Expressjs

app.get("/", (req, res) => {
  ory
    .toSession({ cookie: req.header("cookie") })
    .then((data) => res.json(data))
    .catch(() =>
      res.redirect(`${process.env.ORY_SDK_URL}/self-service/login/browser`),
    )
})

Next.js

export default function Page() {
  const [session, setSession] = useState<Session | null>(null)

  useEffect(() => {
    // Check if the user is authenticated
    const checkSession = async () => {
      try {
        const session = await ory.toSession()
        setSession(session)
      } catch (error) {
        // No valid session found, redirect to Ory login
        window.location.href = `${process.env.ORY_SDK_URL}/self-service/login/browser`
      }
    }

    checkSession()
  }, [])

  return (
    <>
      <pre>{JSON.stringify(session, null, 2)}</pre>
    </>
  )
}

Go

login_handler.go

package main

import (
	"io"
	"net/http"
)

// LoginHandler handles the /login route
func (app *App) loginHandler(writer http.ResponseWriter, request *http.Request) {
	// Get cookies from the request
	cookies := request.Header.Get("Cookie")

	// Try to verify session with Ory
	session, response, err := app.ory.FrontendAPI.ToSession(request.Context()).Cookie(cookies).Execute()

	// If there's an error or session is not active, redirect to login UI
	if err != nil || (err == nil && !*session.Active) {
		http.Redirect(writer, request, app.tunnelUrl+"/self-service/login/browser", http.StatusSeeOther)
		return
	}

	// If session is valid, send the session data as JSON response
	writer.Header().Set("Content-Type", "application/json")
	writer.WriteHeader(http.StatusOK)
	// Use io.Copy to copy the response body to the writer
	io.Copy(writer, response.Body)
}

You can alternatively set return_to to a custom URL. This URL will be used as the return URL for the login flow:

https://$ORY_SDK_URL/self-service/login/browser?return_to=https://example.com/dashboard
