Keep user in shiny app logged in when refreshing browser

markusdumke · April 5, 2019, 9:13am

I have implemented the possibility for users to login inside my shiny app in shiny server (so the login is handled by shiny). Now when a user clicks the refresh button of the browser the app is restarted, so the state of the application is lost, meaning the user is not logged in anymore. Is there a simple possibility to keep the user logged in?

I think it could maybe done with cookies, but I really do not know, how to achieve this. Would appreciate if someone can share some code, on how to implement this.

app.R

library(shiny)
library(shinyjs)


# This would usually come from your user database. But we want to keep it simple.
password_hash <- bcrypt::hashpw('secret123') # Never store passwords as clear text
sessionid <- "OQGYIrpOvV3KnOpBSPgOhqGxz2dE5A9IpKhP6Dy2kd7xIQhLjwYzskn9mIhRAVHo" # Our not so random sessionid
