I wrote a very simple smart contract which emits an event everytime I call one of its functions:

pragma solidity ^0.8.0;

contract MyContract {

    event Score(
        uint date,
        string player,
        string team

    function goalScored(string memory _player, string memory _team) external {
        emit Score(block.timestamp, _player, _team);

Then I deploy the contract using truffle migrate. Finally I interact with the contract within the truffle console. To do so I therefore load the contract by using the following lines of code:

MyContract.deployed().then(function(i) { contract=i;})

Basically everytime Messi scores against a team a I launch the function to emit an Score event.

Here is my question: how can I visualize the list of all events within the truffle console?

What I tried: I ran the goalScored() function 4 times with different inputs and then I tried to used the following command:


But all I got was this:

EventEmitter {
  _events: [Object: null prototype] {},
  _eventsCount: 0,
  _maxListeners: undefined,
  [Symbol(kCapture)]: false
truffle(development)> Uncaught [Error: The current provider doesn't support subscriptions: HttpProvider] {
  domainEmitter: EventEmitter {
    _events: [Object: null prototype] {},
    _eventsCount: 0,
    _maxListeners: undefined,
    [Symbol(kCapture)]: false
  domainThrown: false

Would you be able to suggest a smart and elegant way to achieve my goal?

from truffle develop you could try something like

let c = await MyContract.deployed()
await c.goalScored('a','b')
let events = await c.getPastEvents('Score',{ fromBlock:0, toBlock:'latest'})

furthermore, if you need ALL events, you could use

c.getPastEvents('allEvents',{ fromBlock:0, toBlock:'latest'})

full truffle develop input:

let c = await Messi.deployed()
await c.goalScored('first','inter')
await c.getPastEvents('allEvents',{fromBlock:0})

example output:

  • Thanks for the answer! I just run your code but I get an empty list for some reason.... do you know what the issue could be? Sep 30, 2021 at 15:30
  • Hi, I tried inside truffle console; allow me some time and I'll update the answer with the whole list of commands (it's already the one above though..)

  • @FedericoGentile a note; I replicated your situation if you deploy with c.deployed() without the migration. I don't know why it behaves this way
