cljs-web3's Issues

Cross-domain solution of web3.js request provider

I used nginx reverse proxy to deal with cross-domain problems， but web3.js request https://xxx.xxx/5b44529e903c4ebf9d60e4d01c965489 throw "Uncaught Error: Can't autodetect provider for "xxx.xxx/5b44529e903c4ebf9d60e4d01c965489""

The cross-domain configuration of nginx is as follows

location /5b44529e903c4ebf9d60e4d01c965489{

if ($request_method = 'OPTIONS') {
    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
    add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';

    add_header 'Access-Control-Max-Age' 1728000;
    add_header 'Content-Type' 'text/plain; charset=utf-8';
    add_header 'Content-Length' 0;
    return 204;
 }

    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';

import data from './abi'
import Web3 from 'web3';

        var contract = '';
        //web3 = new Web3("https://mainnet.infura.io  /v3/5b44529e903c4ebf9d60e4d01c965489");
        web3 = new Web3("www.xxx.xxx/5b44529e903c4ebf9d60e4d01c965489");
        contract = new web3.eth.Contract(data.abi, data.address);
        Vue.prototype.infuraContract = contract;
        Vue.prototype.infuraWeb3 = web3;
        //Web3 version "web3": "^1.0.0-beta.36"；
    }
}

Method: toWei was not found in object.

I'm new to web3 and clojure.
I don't know what I'm doing wrong.
First : is this lib still supported?

I have included in my project.clj:

[cljs-web3 "0.19.0-0-11"]

And in my views.clj:

(ns project.views
  (:require
   [re-frame.core :as re-frame]
   [multis.subs :as subs]
   [cljsjs.web3]
   [cljs-web3.core :as web3]
   [cljs-web3.eth :as web3-eth]
   ))

; activiate ethereum backend
(def enabled (js/ethereum.enable (fn [err res] (
  (.log js/console res)
))))

; get w3 instance
(def my-web3 (or (aget js/window "web3")
             (if goog.DEBUG
               (web3/web3)
               (web3/create-web3 "https://morden.infura.io/metamask"))))
(def w3 (new (aget js/window "Web3") (aget js/window "ethereum")))

(def amount (web3/to-wei 1 :ether))

I get an error:

Failed to load project/views.cljs Method: toWei was not found in object.

What am I doing wrong?

npm-deps support?

Hey Matus! hope you're doing well :)

Was just wondering if you have explored using :npm-deps instead of the cljsjs/web3 dependency? This would allow for dead code elimination of stuff inside the web3.js dependency and remove the need for externs to be updated whenever the API changes.

Navigating ClojureScript Fire Swamps has some slides at the end describing the process and benefits of native module processing.

"Cannot send value to non-payable constructor" even though the constructor is payable

First of all, congrats on the great work! Loving making dapps in ClojureScript so far thanks to your excellent libraries.

I'm attempting to create a contract while also sending it some ether. My event handler returns an effect like this:

   {:web3/call {:web3 web3
                :fns [{:fn web3-eth/contract-new
                       :args [abi
                              {:data bytecode
                               :arguments []
                               :gas 400000
                               :gasPrice "30000000000"
                               :value 1000000}]
                       :on-success [:contract-created]
                       :on-error [:contract-creation-error]}]}}

On Chrome, I get the following error:

However, my constructor is in fact payable, as can be seen in both the Solidity source and the compiled code:

// skipping non-relevant sections
{
"abi": [
    {
      "inputs": [],
      "payable": true,
      "stateMutability": "payable",
      "type": "constructor"
    }
  ]
}

Any idea why this might be happening?

Question: What do you use on the Server Side?

I want to use Clojure on the server-side to interact with ethereum. What do you use to do this? Do you use cljs-web3 with clojurescript on the server?

Support for web3.js 1.0?

Does this library support web3.js 1.0 ?

Function to obtain web3 instance injected by Mist / Metamask

Hey again :) I was looking through the core namespace and documentation and was just wondering if there's a built in way to obtain the web3 object injected by Metamask et al?

If there's not then maybe it's worth to add this? Not sure how easy this is to uniformly implement across Mist / Metamask /... but currently users need to extern js/window.web3 themselves which introduces some avoidable friction in using this library.
