there is a way to do a validation?

[JManuelMT-zz]

Hello, maybe this is not an issue but I coud not find another place to ask for help, there is a way to add validation depending on a session variable or something like that?
for example:
let color;
if(/* Here a condition like req.session.mycondition * /)
color = 'red'
else
color = 'blue'

module.exports = { color }

Thanks in advance

You can do that with normal Sass, no?

Maybe I am worng but I don´t think so, I mean I need a variable that is on my node session for example
app.get('/',function(req,res){
myvar=req.session.myvar;
}

I understand that maybe this is not directly related with your library (I m not expert on node js) but is the way I'm trying to implementing it, could you help me please?

If you make a sample repo with your code, sure.
