Hi @dattnguyen82, thanks for share the repo. I have seen your medium's post and I tested your repo and it worked well with my own contract address. However, when i tried to put in practice your implementation with my own code, the event does not emit. So, i do not see how do you trigger your event?

I appreciate your response.

This is my solidity implementation:

pragma solidity ^0.4.23;

contract SimpleStorage {
uint v1;
uint v2;

constructor() public {
v1 = 0;
v2 = 0;
}
event simpleEvent(uint x, uint y);

function set(uint x, uint y) public {
v1 = x;
v2 = y;
}

function () public {
require (v1 < v2);
emit simpleEvent(v1, v2);
}
}

This is my web3js method to call the contract:

instance.methods
.set(1, 6)
.send({ from: "0xE8d5487CaEbFB3F3e93304161cAd0d5d3078B033" });

var event = instance.events
.simpleEvent()
.on("data", function(event) {
let simpleEvent = event.returnValues;
// Podemos acceder a los 3 objetos de este evento mediante el objeto event.returnValues:
console.log("A new zombie was born!", simpleEvent.x, simpleEvent.y);
})
.on("error", console.error);
};
