How can i remove some symbols from Validator isAlphanumeric like "_" "-" ".", what I want is the user can register with these symbols now it only validate letters and numbers, I don't know if isAlphanumeric is what i'm looking for or there is some other way to implement this.
Auth.js
else if (!Validator.isAlphanumeric(req.body.username, 'en-US')) {
return next(
createError(
400,
"Invalid username: Only letters and numbers"
)
);
}
I just want to take out "_" "-" "." from it and keep the others.
