How do i move to next or prev question in a quiz app. i want to fetch the questions from the database

    Template.quiz.helpers({
         //add you helpers here
    'questionList': function () {
       return Questions.find({},{limit: 1}).fetch();
    }
      });



      Template.quiz.events({
          'click .next': function (evt) {
             evt.preventDefault();
   }
   });

database
{
"_id": “kAKbfLRHFZinrrRZv”,
“selected_subject”: “English”,
“question”: “ekek”,
“ans_A”: “e”,
“ans_B”: “q”,
“ans_C”: “t”,
“ans_D”: “o”,
“correctAns”: “e”
}

Client:

// If you've removed autopublish using `meteor remove autopublish`, uncomment the next line
// Meteor.subscribe('questions');

Session.setDefault('questionNumber', 1);

Template.quiz.helpers({
    //add your helpers here
    'questionList': function () {
       return Questions.findOne({questionNumber: Session.get('questionNumber')});
    }
 });

Template.quiz.events({
   'click .next': function (evt) {
      evt.preventDefault();
      var currentQuestionNumber = Session.get('questionNumber');
      Session.set('questionNumber', currentQuestionNumber + 1);
   }
});

Server: (If you’ve removed autopublish using meteor remove autopublish, put the following in /server/publish.js)

Meteor.publish('questions', function () {
  return Questions.find();
});

Database:

{
  "_id": "kAKbfLRHFZinrrRZv", 
  "selected_subject": "English", 
  "question": "ekek", 
  "ans_A": "e", 
  "ans_B": "q", 
  "ans_C": "t",
  "ans_D": "o",
  "correctAns": "e",
  "questionNumber": 1
}

Give each question its own questionNumber field, with values 1, 2, 3, …

Thank you @babrahams, please how do i add a questionNumber field to my meteor db and make it auto increment by default?

When you add a question, you will do something like this:

CLIENT AND SERVER:

Meteor.methods('addNewQuestion', function (newQuestionData) {
  check(newQuestionData, Object);
  check(newQuestionData.question, String);
  // Plus various other checks
  Questions.insert(newQuestionData);
}

where the newQuestionData is something like this:

{
  "selected_subject": "English", 
  "question": "ekek", 
  "ans_A": "e", 
  "ans_B": "q", 
  "ans_C": "t",
  "ans_D": "o",
  "correctAns": "e"
}

Change the addNewQuestion method to:

Meteor.methods('addNewQuestion', function (newQuestionData) {
  check(newQuestionData, Object);
  check(newQuestionData.question, String);
  // Plus various other checks
  var existingQuestionCount = Questions.find().count();
  newQuestionData.questionNumber = existingQuestionCount + 1;
  Questions.insert(newQuestionData);
}
