Did anyone find any progress in this? Just want to listen to pending changes in some way.

SilentCicero commented 6 years ago

Hi, can you post your code or at least some, it may just be the way your using the module. If not there are alternatives.

Just a heads up I will be putting up bounties on a ton of stuff for ethjs fixes. If there is a problem we can get it patched shortly.

Just trying those simple alternatives like in https://jsfiddle.net/karvex/fantokn4/ . Neither of them seems to react to a pending transactions. I tried with testrpc and a private geth node.

  1. Start geth node or testrpc
  2. Start web application.
  3. Open web browser. Use correct network with Metamask.
  4. Close browser.
  5. Open web browser.
  6. Write password on MetaMask
  7. Change to correct account.
  8. Make a transaction on web application with Metamask.
  9. Nothing happens to Filter Events. https://jsfiddle.net/karvex/fantokn4/

Can you specify what provider you are using? is it infura?

I'm using Metamask and they are using infura.

What alternatives is there anyways regarding getting pending transactions?

karvex commented 6 years ago

Is the workaround to use web3.js and eth.js in parallell? Like doing everything in eth.js, but only pending transactions with web3.js?

SilentCicero commented 6 years ago

Hi, I definitely think it should be doable in just ethjs. The problem is maybe to do with how I'm handling contract events.

I wrote a small module that I believe contains most of what people actually want for their dapp including what you are after.

Checkout ethjs-extras.

It's a little radical, and up on npm. You can define contract interfaces in solidity abi format. And can listen for new events by just using contract.onEvent(callback).

I would check it out. It's even lighter than all of ethjs ;)

onEvent sounds good, but how does it solve listening to pending transactions?
