Get the vote contract string in this case 0x4610b7b59920b760d1164406a6f13f09043b6af3 and replace the contract variable in the event.js file this string will change evrytime you do a truffle deploy.

Go one directory up and run the index.js file to get node running

$ node event.js

If no errors show up you can do GET and POST requests to cast and retrieve votes. There are only two candidates

GET Vote count for candidate 1

$ curl -X GET http://localhost:8080/count/1

"0"

To cast vote you'll need the address of an account on the ganche network.

$ curl -X GET http://localhost:8080/count/1

"1"

Once the address of an account has been used to vote it cannot be used again. When we try to add property

$ curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d "candidate=2&account=0x25660625C2919b6998c5dD7300ACE7a03db89855" http://localhost:8080/vote 

"Property has been transferred"
