Recomended way to do authentification?

[AlexKotik]

I'm sorry, if I'm missing something, but is there a recomended way to do user authentification in Trame-based app? I couldn't find docs about it for some reason.

No worries, I guess there is many path depending on what you are looking for.
A better one would be to handle authentication outside so you aren't allowed to run a trame server process before any prior authorization.

Otherwise, you can easily manage it yourself within trame by creating 2 methods that build a layout. You start with your login UI and then if the login/pass are satisfactory, you just execute the second method to build your full app UI.

Are there some examples?

Are you asking from within the trame process rather than before hand?

If so something like that

from trame.app import TrameApp
from trame.ui.html import DivLayout
from trame.widgets import html

class AuthDemo(TrameApp):
   def __init__(self):
        super().__init__()
        self.login_ui()

  def check_auth(self):
       if self.state.secret == "valid-secret":
           self.app_ui()

  def login_ui(self):
      with DivLayout(self.server):
          html.Input(v_model=("secret", ""))
          html.Button("Validate", click=self.check_auth)

  def app_ui(self):
      with DivLayout(self.server):
          html.Div("You are logged in")

if __name__ == "__main__":
     app = AuthDemo()
     app.server.start()
