Truffle WebPack problem

Question

I'm trying to use webpack in a truffle project. I follow this guide https://github.com/ConsenSys/truffle/wiki/Using-Truffle-and-Webpack-(beta).

At point 8 in my app.js I add this line:

var TestRPC = require("ethereumjs-testrpc");
  if (typeof web3 !== 'undefined') {
  web3 = new Web3(web3.currentProvider);
} else {
 web3 = new Web3(new web3.setProvider(TestRPC.provider()));
}

Unfortunately when i require ethereumjs-testrpc the Chrome console output: Uncaught Error: Cannot find module "fs".

I try to add in my webpack config: node: { console: true, fs: 'empty', net: 'empty', tls: 'empty' }

with no success.

Tks for help.

Answer 1

As far as My understanding goes ,ethereumjs-testrpc is a node module and the way you want to test your code is through node.js. And I believe, You are trying execute the javascript which meant to be running in the node.js environment, which is why you mentioned chrome browser. fs module means file system module which is generally used in node.js environments to access the file system.Some modules like fs in node are not compatible with chrome ( browsers), they are meant to be running in servers ( node.js)

Not from Consensys Truffle but a good boilerplate for truffle + webpack. https://github.com/niran/dapp-boilerplate
