Web3 with Webpack Build not found without webpack-dev-server
With a Reactjs webpack project I am able to run webpack dev server and access my index.html with web3 picked up.
If I build the project and open the index.html in Chrome then web3 is not detected.
Everything works when running webpack-dev-server --mode development --open --hot
but with webpack --mode development then web3 is not injected
The purpose of my app is a tool to be run locally, it does not have to be served from anywhere public, also I don't see that I need to run a lite server to serve the content.
- web3: 1.0.0-beta.36
- webpack: 4.22.0
- webpack-cli: 3.1.2
webpack-dev-server: 3.1.8
import './index.css';
import IxoTimelockApp from './components/IxoTimelockApp';
import InstallMetaMask from './components/install-
metamask/install-metamask-component.jsx';
let regeneratorRuntime = require("regenerator-runtime");
class App extends Component {
state = {
web3Obj:null
}
componentDidUpdate(prevprops) {
if (prevprops != this.props){
this.setState({web3Obj: this.props.web3Obj})
}
}
componentDidMount(){
window.addEventListener('load', async () => {
// Modern dapp browsers...
if (window.ethereum) {
window.web3 = new Web3(ethereum);
try {
// Request account access if needed
await ethereum.enable();
this.setState({web3Obj: window.web3})
} catch (error) {
// User denied account access...
}
}
// Legacy dapp browsers...
else if (window.web3) {
window.web3 = new Web3(web3.currentProvider);
this.setState({web3Obj: window.web3})
}
// Non-dapp browsers...
else {
console.log('Non-Ethereum browser detected. You should consider trying MetaMask!');
}
});
}
render() {
if(this.state.web3Obj) {
return <TimelockApp/>
}else return <InstallMetaMask/>
}
}
export default App;
const wrapper = document.getElementById("root");
wrapper ? ReactDOM.render(<App />, wrapper) : false;
