npm run serve fails, npm start works w/o any problems

[nephix]

Hi,

I've been running my app with npm start and don't get any error in my command line as well as browser console. When I run npm run serve I get a Hash history needs a DOM error:

$ npm run serve

[email protected] serve /Users/nephix/Development/preact/Aye/repository/AyePWA
preact build && preact serve

My dependencies are:

"dependencies": {
  "preact": "^8.1.0",
  "preact-compat": "^3.16.0",
  "preact-redux": "^2.0.2",
  "react-dom": "^15.6.1",
  "react-motion-drawer": "^2.1.5",
  "react-router-dom": "^4.1.1",
  "redux": "^3.7.1"
}

I'm using HashRouter from react-router-dom in my App Component:

import { h, Component } from 'preact';
import { HashRouter, Route } from 'react-router-dom';
import Order from '../routes/order';
import Login from '../routes/login';
import OrderLocation from '../routes/order_location';
import Item from '../routes/item';

export default class App extends Component {
	render() {
		return (
                <div id="app">
                  <HashRouter>
                    <div>
                      <main>
                        <Route exact path="/" component={Order} />
                        <Route path="/order/location" component={OrderLocation} />
                        <Route path="/login" component={Login} />
                        <Route path="/item/:index" component={Item} />
                      </main>
                    </div>
                  </HashRouter>
                </div>	
		);
	}
}

(simplified version)

I'm posting this in preact-cli because the error seems to come during the production build process, while the development build process works fine. I'm not sure exactly what the error is. Has anybody encountered a similar problem and knows a workaround? Thanks guys

Hi. This is a prerender issue, you can see a workaround here #178 .

[thangngoc89]

Please discuss this over #178.
