反应代码拆分不起作用

Question

After reading this post , I tried to use react-code-splitting to splite my JavaScript bundle.

Webpack Version: 3.10.10

PageRouter.js

import Async from "react-code-splitting";
import React from "react";
// import Home from "pages/home/Home";
// ...

const Home = () => <Async load={import("pages/home/Home")} />

export default class PageRouter extends React.Component {
    render() {
        return(
            <Router history={browserHistory}>
                <Route exact path="/" component={Home} />
            </Router>
        );
    }
}

Webpack Dev Server Error

It seems like just a syntax problem?

export default class PageRouter extends React.Component {
    render() {
             ^
        return (...);
    }
}
webpack: Failed to compile.

I can't really tell what the root issue is but, I suspect that perhaps you are missing some babel plugins. Check out Paragons . It uses React Loadable. You can cross check the webpack config and examine the usage:

Start from:

export const CodeSplitPageLoadable = createLoadable('./demo/components/CodeSplitPage')

in routes.js .
