A full stack application made using node.js express.js and mongoDb as database.

the frontend

On the front, we have set views to make the application interactive, and the view engine is ejs.

The endpoints of the applicion

/ -> to make a new poll
/poll/:redirectKey -> to vote a poll
/polls/results/:redirectKey -> to view the result of a particular poll

The procedure to run the app

Start the project using npm run dev and go on to localhost:3000 to view your application in action. Make sure to Start the mongoDb server using mongod or your application wont run nicely.

How Are poll Id's generated?

In the project, we have created a foler as functions, where there is a file as makeid.js, which has the following code.

module.exports = function (length) {
  var result = "";
  var characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
  var charactersLength = characters.length;
  for (var i = 0; i < length; i++) {
    result += characters.charAt(Math.floor(Math.random() * charactersLength));
  }
  return result;
};

This program generates Random id's that can be used as poll id or redirectKey for each of the polls.

Enjoy your powerful application
