Uncaught TypeError: soljson.cwrap is not a function #226

Open KaceyBolman opened 6 years ago

KaceyBolman commented 6 years ago

Hello. friends. I am trying to import solc js in react mobx project. But when use code "var solc = require('solc')", i am getting "Type error soljson.cwrap is not function". If anyone know the way to fix or has sample, Please teach me.

Hi, I got the same problem. node v10.4.1 npm v6.1.0 Created a react app from scratch (without using create-react-app script) App running. npm i -s solc

Then at first hit of var solc = require('solc') got the error

TypeError: soljson.cwrap is not a function
setupMethods webpack:///./node_modules/solc/wrapper.js?:9:21
<anonyme>webpack:///./node_modules/solc/index.js?:3:18

I'm running in a dev environment, using webpack-dev-server.

Hope you got enough informations.

KaceyBolman commented 6 years ago

node v6.11.2 npm v3.10.10 i tried to use solcjs my old react app for electron, mobx and webpack. But when added a line of var solc = require('solc'). Uncaught TypeError: soljson.cwrap is not a function at setupMethods (eval at (bundle.js:3650), :9:29) at eval (eval at (bundle.js:3644), :3:18)

xas commented 6 years ago

Seems related to #31 but not sure if same reasons.

CorentinPacaud commented 6 years ago

So, is it fixed ?

muhammadikramzafar commented 5 years ago

For the One Using Electron js . I had the same issue but resolved by moving var solc = require('solc') from client side to server side . As sloc does not work on client side . Hope this will resolve the issue

I have a solution, but it is a little complicated...

My environment is Node.v13.11.0, Create-React-App(ejected), Chrome. I encountered both this problem and the problem in issue #456.

When I directly use require('solc') in App.js, the chrome gives an error.

Uncaught RangeError: WebAssembly.Compile is disallowed on the main thread, if the buffer size is larger than 4KB. Use WebAssembly.compile, or compile on a worker thread.

Follow by the solution in ##456, I tried to use Web-Worker and Worker-Loader (React), to move the whole solc module into the worker thread.

The following two cases show the difference between a main thread import & worker thread import.

Case1:

index.html

    <script type="text/javascript" src="http://127.0.0.1:8080/static/soljson.js"></script>

App.js

console.log('main soljson', window.Module);

Output

Compare two output messages, we can find that the module required by main thread was somehow incompleted. I guess it is caused by some restriction (such as file size limit in main thread) in WebASM.

So, here is my solution:

Step1. Use Web-Worker to load soljson. The soljson module was store in object Module as mentioned in Readme.md.

importScripts('http://127.0.0.1:8080/static/soljson.js'); // Local copy of https://ethereum.github.io/solc-bin/bin/soljson-v0.6.6+commit.6c089d02.js
let soljson = Module;
console.log('worker soljson = ', soljson);

Step2. The solc object we use is defined as setupMethods(soljson), while setupMethods was defined in node_modules/solc/wrapper.js. We cannot just copy this file out, because this file require other packages. The only solution I came out is to create a new Webpack project to organize the mess relationship.

webpack.config.js

const path = require('path');

module.exports = {
    entry: './src/index.js',
    output: {
        filename: 'solc.bundle.js',
        path: path.resolve(__dirname, 'dist'),
        globalObject: "self",
    },
    externals: {
        fs: {
            root: 'fs',
        },
        module: {
            root: 'module',
        }
    }
};

src/index.js

import wrapper from 'solc/wrapper';
var solc = wrapper(Module);
try{
    global.solc = solc; // Note that the global object in WebWorker is not `window`
} catch (err) {
    console.log("[Webpack-bundle] err ", err);
}

The webpack generate file solc.bundle.js was copied to static asset directory, an we can finally get the solc out in worker thread.

importScripts('http://127.0.0.1:8080/static/soljson.js'); // Local copy of https://ethereum.github.io/solc-bin/bin/soljson-v0.6.6+commit.6c089d02.js
let soljson = Module;
console.log('worker soljson = ', soljson);
importScripts('http://127.0.0.1:8080/static/solc.bundle.js');
console.log("solc = ", solc);
var input = {
    language: 'Solidity',
    sources: {
      'test.sol': {
        content: 'import "lib.sol"; contract C { function f() public { L.f(); } }'
      }
    },
    settings: {
      outputSelection: {
        '*': {
          '*': ['*']
        }
      }
    }
  };

  function findImports(path) {
    if (path === 'lib.sol')
      return {
        contents:
          'library L { function f() internal returns (uint) { return 7; } }'
      };
    else return { error: 'File not found' };
  }

  // New syntax (supported from 0.5.12, mandatory from 0.6.0)
  var output = JSON.parse(
    solc.compile(JSON.stringify(input), { import: findImports })
  );

  // `output` here contains the JSON output as specified in the documentation
  for (var contractName in output.contracts['test.sol']) {
    console.log(

BUMP.

This is preventing my inline browser ethereum toolset from working in chrome:

soljson-v0.6.9+commit.3e3065ac.js:1 failed to compile wasm module: RangeError: WebAssembly.Compile is disallowed on the main thread, if the buffer size is larger than 4KB. Use WebAssembly.compile, or compile on a worker thread. instantiateSync @ soljson-v0.6.9+commit.3e3065ac.js:1 createWasm @ soljson-v0.6.9+commit.3e3065ac.js:1 (anonymous) @ soljson-v0.6.9+commit.3e3065ac.js:1 soljson-v0.6.9+commit.3e3065ac.js:1 Uncaught RangeError: WebAssembly.Compile is disallowed on the main thread, if the buffer size is larger than 4KB. Use WebAssembly.compile, or compile on a worker thread. at instantiateSync (soljson-v0.6.9+commit.3e3065ac.js:1) at Object.createWasm [as asm] (soljson-v0.6.9+commit.3e3065ac.js:1) at soljson-v0.6.9+commit.3e3065ac.js:1

It appears that soljson-v0.6.9 is incorrectly loading webassembly on the main thread instead of a worker thread. I'm not even sure what that means, but it's breaking things for me downstream now.

If you are using react, you need to use web worker. You can use https://github.com/rexdavinci/browser-solidity-compiler to get this done. It comes with typescript support as well.
