queryFilter with transactionHash

[pofulu]

Currently if we want to get the events which emited by specific transcation, we need to use queryFilter with blockHash, and filter with transactionHash again:

const tx = await contract.mint();
const receipt = await tx.wait();
const events = await contract.queryFilter(contract.filters.Mint(), receipt.blockHash);

for (const event of events.filter(e => e.transactionHash == receipt.transactionHash)) {
    const { boo, foo, tokenId, whatever } = event.args;
    // Do something
}

It would be more convenient if we could use queryFilter with transactionHash or even get events driectly from receipt , any ideas?

( I know we can get events by receipt.events, but it seem that we cannot make the type detection works with this way)

How are you having the type detection? If you are using typechain, you can just cast to the type:

import { MintEvent } from '../typechain/ContractName';

receipt.events as MintEvent[]

it help, but this doesn't work well if you are working with ERC-20 and Ethereum

other way, but I don't like also:

smartContract.once('Claim', (datat) => {
      console.log({data})
})

Filter with transactionHash is necessary, if multiple Mint event triggered in very close time, client may get others result.
