Let's take the example of the SimpleStorage
contract that comes with the truffle box drizzle-box
How can we listen to the event StorageSet
and console.log
it to the JS console?
import SimpleStorage from './../build/contracts/SimpleStorage.json'
const drizzleOptions = {
web3: {
block: false,
fallback: {
type: 'ws',
url: 'ws://127.0.0.1:8545'
}
},
contracts: [
SimpleStorage
],
events: {
SimpleStorage: ['StorageSet'],
},
polls: {
accounts: 1500
}
}
export default drizzleOptions

I guess you use Metamask, so the problem might be the following: "The current provider doesn't support subscriptions: MetamaskInpageProvider".
I don't either see this error message, since drizzle doesn't print it. You can have a look here. On this way, you should be able to test that event subscription thing on your own/manually. Something like that:
Here you can find the documentation for web3 events.
Optionally, you could check for events in the transaction receipt.
