How to sign up user and then keep them signed in and access current user Parse Server?

Question

I am trying to get a user to sign up, I have the HTML form working etc. I just need to handle the sign up itself.

The user is successfully created BUT I'm not sure how to keep the user logged in or access the current user logged in as a Parse.User object.

app.post("/sign-up", function (req, res) {

var userObject = new Parse.User();
userObject.set("username", username);
userObject.set("password", password);
userObject.set("email", email);

userObject.set("supportEmail", email);

userObject.signUp(null, {success: function(user) {
    //success

 res.redirect('/admin'); 

  },
  error: function(user, error) {
    //show error
    console.log(error.message);
    res.render('sign-up', {success:false, errorMessage:error.message});

  }
});

}); Not sure what to do in order to keep them logged in and to acess the Parse.User object for the current user.

Answer 1

you can save in global variable in your application. also you can export user object to use in other files. There is another way to store in database or one other way is to app.locals.user = userObject

    var userObject = new Parse.User();

app.post("/sign-up", function (req, res) {

    userObject.set("username", username);
    userObject.set("password", password);
    userObject.set("email", email);

    userObject.set("supportEmail", email);

   app.locals.user = userObject;

    userObject.signUp(null, {success: function(user) {
        //success

     res.redirect('/admin'); 

      },
      error: function(user, error) {
        //show error
        console.log(error.message);
        res.render('sign-up', {success:false, errorMessage:error.message});

      }
    });


module.exports.userObject = userObjetct;

The signup promise resolves in an authentication object along with the session token.

Then you can use it and call Parse.User.become to retrieve the user class.

Parse.User.become("session-token-here").then(function (user) {
  // The current user is now set to user.
}, function (error) {
  // The token could not be validated.
});
