ethjs's Issues

Tx `from` should default to `selectedAccount`.

Web3 defaults a tx with no from field to be the current selectedAddress, and this makes for some pretty obvious and clean web3.eth.sendTransaction calls.

I'd vote to loosen the enforcement of the from parameter to allow this to follow to the provider level.

doc bug: bignumber.js api png

https://github.com/ethjs/ethjs/blob/master/docs/user-guide.md has an image from bignumber.js but ethjs uses BN.js, different animal.

Getting error insufficient funds for gas * price + value

we find the pending transaction. After finding it, we want to swap for the same token.
SwapExactEthtoToken

this error changes from time to time as shown below why get these errors ?

Error code -32000 Message is changing

Insufficient balance for transaction
Gas fee too low for this transaction
Replacement underpriced

ethjs-abi and ethjs-query are out-of-date

The ethjs-abi and ethjs-query dependencies are out-of-date. Please upgrade and deploy a new version to npm.

Examples of things that are broken

ethjs-abi encodeSignature method does not exist yet.
ethjs-query does not handle promise rejections correctly and results in UnhandledPromiseRejectionWarning exceptions. See #21 as well.

Current workaround is to use the child libraries directly, but that defeats the purpose of having the parent ethjs library at all.

Is there any way to create a RLP encoded transaction with ethjs?

eth.contract method result not iteratable

should be able to write

  const [ resultBn ] = await uniswapv1Dai.getEthToTokenInputPrice(oneEth)

error

TypeError: (intermediate value) is not iterable

workaround

  const { 0: resultBn } = await uniswapv1Dai.getEthToTokenInputPrice(oneEth)

Error when calling contract function with address as argument

Issue Type

Description

When calling a Solidity function that takes only one argument, an address, I get the following error:

Uncaught (in promise) Error: [ethjs-query] while formatting inputs '[{"to":{"0":"0x409ba3dd291bb5d48d5b4404f5efa207441f6cba"},"data":"0x70a08231000000000000000000000000627306090abab3a6e1400e9345bc60c78a8bef57"},"latest"]' for method 'call' error: Error: [ethjs-format] hex string '[object Object]' must be an alphanumeric 42 utf8 byte hex (chars: a-fA-F) string, is 0 bytes

Full steps are below. Please let me know if you need any more information 😄

Steps to reproduce

The relevant function in my contract is from OpenZeppelin.

/**
* @dev Gets the balance of the specified address.
* @param _owner The address to query the the balance of.
* @return An uint256 representing the amount owned by the passed address.
*/
function balanceOf(address _owner) public view returns (uint256 balance) {
    return balances[_owner];
}

I create a contract with EthJS:

const contract = eth.contract(ABI.abi, ABI.bytecode).at(address);

This is successful and gives me a contract object that looks like:

Object
  Approval:()
  Mint:()
  MintFinished:()
  OwnershipTransferred:()
  Transfer:()
  abi:Array[21]
  address:Object
  allowance:()

With the contract initialised, I try to call the balanceOf method.

const balance = await coinContract.balanceOf(""0x627306090abab3a6e1400e9345bc60c78a8bef57"");

This is where it fails and throws the error 😢 ,

I just couldn't figure why between two run of my CI build system I had completely different npm install log result...

I finally figured out that ethjs has just been updated, and I don't know how you managed guys, but [email protected] is now a DEPENDENCY of EthJS!!! :D

Unhandled promise rejection on errors

Issue Type

Bug

Description

Produce unhandled promise rejection on each error in Node.js and Browser.

Steps to reproduce

Initialize eths:

const eth = new Eth(new Eth.HttpProvider('...url...'));

Call any method:

await eth.contract(abi, bytecode).new();

Versions

Node/NPM: 9.3
Browser: Chrome 63

ethjs-contract out of date

The ethjs-contract was upgraded to 0.2.x.

Example of things that are broken: eth.contract(...).new() returns undefined instead of a promise if no callback is given.

Current workaround is to use the child libraries directly.

Allow schema to be defined at runtime

Maybe this turns it into a very different module, but:

As a wallet developer who sometimes wants to add methods, but doesn't want to deal with PRs and npm publishes of schema, ethjs, and all their dependents, I'd rather just add a getSchema RPC method which allows my web3 context to define its own expanded set of available methods.

Would you merge a change like that?

eth.contract is not a function

const token = eth.contract(tokenABI).at('0x6e0E0e02377Bc1d90E8a7c21f12BA385C2C35f78');

TypeError: eth.contract is not a function

why does it say so , I even tried "C"ontract web3js

Include RPC error message somewhere in eth error object body.

MetaMask returns some useful errors! This would be a great thing to standardize around, error codes for the clients.

"User denied signature" is a very good example of a useful error to be aware of as a UI.

Can't store string at smart contract

When I pass string to the smartcontract method, it says :

Error: [ethjs-abi] invalid hex or buffer, must be a prefixed alphanumeric even length hex string
    at hexOrBuffer (index.js:41)
    at Object.encodeFixedBytes [as encode] (index.js:144)

Cannot call transfer method of smart contract

Issue Type

It's a bug and I am not sure how to fix it.

Description

I am using ethjs in a react project to interact with a smart contract.

What I do so far:

Accessing the address that the user is currently logged in with in meta mask ✅

window.web3.eth.getAccounts(function(err,accounts) {
	resolve(accounts[0]);
});

Reading values from the Smart Contract such as the Symbol, Currency Name, Balance for Address ✅

const OASContract = eth.contract(abi).at('0x559623d3660bbae4ee3c90c6ad600d54a520b792');

OASContract.symbol().then(function(result) {
	resolve(result["0"])
});

OASContract.balanceOf(address).then(function(result) {
	resolve(result.balance)
});

OASContract.name().then(function(result) {
	resolve(result["0"])
});

This all works. But now I want to call the transfer method of the SC and this is where I get lost.

Steps to reproduce

OASContract.transferFrom(_from, _to, amount, {from: _from, gas:55000})

Now, this does not work. I get some weird messages in the console:

XML Parsing Error: no root element found
Location: https://ropsten.infura.io/C2D8VJd9N6XXXXXXXXX
Line Number 1, Column 1:

Code example is from user guide

const Eth = require('ethjs');
const eth = new Eth(new Eth.HttpProvider('http://localhost:8545'));

const filter = new eth.filter.PendingTransactionFilter()
.new()
.then((result) => {
  // result <BigNumber ...> filterId
})
.catch((error) => {
  // result null
});

const watcher = filter.watch((error, result) => {
  // result null ['0xfd234829...', '0xsf2030d1...']
});
watcher.stopWatching(cb);

filter.uninstall()
.then((result) => {
  // result true
})
.catch((error) => {
  // result null
});

How do you add an account?

Issue Type

Bug (https://github.com/ethjs/ethjs/blob/master/.github/CONTRIBUTING.md#bug-reports)
Feature

Description

Add some documentation on how to add a private key or HD wallet to eth instance.

Steps to reproduce

There doesn't seem to be any sort of accounts or wallet available on the eth object. The docs only mention going to look at the other packages like ethjs-accounts, then going there doesn't show how it interacts with ethjs. All documentation just leaves out any mention of how to add an account.

Update getTransactionSuccess to decode logs

Update getTransactionSuccess method to optionally decode logs

Issue Type

Description

The getTransactionSuccess method is helpful, but I'd like it to be able to decode returned logs as well. The method could either take as argument an ABI or could be added as a method to a contract instance (i.e. contractInstance.getTransactionSuccess("<txHash>")).

I've found myself creating a log decoder (i.e. const decoder = Eth.abi.logDecoder(<ABI>)) and running logs returned via getTransactionSuccess through that decoder, and it would be nice to have the method do that for me.

Not Working for me

Add to bower

ethjs is currently in NPM

It would be great if it was in bower also.

[Feature] Static or CDN version.

Started working with ethjs recently and one of the pain points was including it for online examples,
( had to use the one from one of the sample files) and couldn't make one with browserify. It also feels like this should be included front and center since your landing page states "Only 103 kB minified!"

Thanks

Love love love this API, so much nicer to work with than web3.js.

Unable to write tests for events when using Solidity Events

The convention when writing Solidity Smart Contracts is to capitalize events (http://solidity.readthedocs.io/en/develop/structure-of-a-contract.html#events) aka

contract SimpleAuction {
    event HighestBidIncreased(address bidder, uint amount); // Event

    function bid() payable {
        // ...
        HighestBidIncreased(msg.sender, msg.value); // Triggering event
    }
}

Such a contract will generate a javascript function that will appear as

SimpleAuction.HighestBidIncreased

But if you try to use the ABI when writing tests for ethjs, you will anger ESLint with the error:

A function with a name starting with an uppercase letter should only be used as a constructor  ne
w-cap

The workaround is to write solidity contracts with events starting with a lower case character, which isn't ideal if there are linting constraints introduced in Solidity which force uppercase event names.

Getting error when decoding event with indexed fields.

Hi! I'm using Ganache 1.0.1 and ethjs 0.4.0.
Here how i use watcher:

this.FightFinished = Contracts.zoneContract.FightFinished(
  { toBlock: 'latest', player: Client.activeAccount }
)
this.FightFinished.new()
this.FightFinished.watch(r => {  
})

I believe this was outlined at https://github.com/ethjs/ethjs-abi/issues/15
But no response at all, i'll try get response here instead.
