Does server-side rendering with react-loadable work with Webpack 4 and Babel 7? I've been unable to get it working successfully while following the instructions.
After following just the client-side steps, Webpack correctly outputs separate chunks for each loadable component and this is reflected when I load the page in the browser (ie: the chunks are lazy-loaded).
After following all the SSR steps, however, the server throws the following error:
Error: Not supported

My routes/index.js file:
import React from 'react';
import Loadable from 'react-loadable';
import Loading from '../components/Loading';
export default [
{
path: '/',
component: Loadable({
loader: () => import('./controllers/IndexController'),
loading: Loading,
}),
exact: true,
},
{
path: '/home',
component: Loadable({
loader: () => import('./controllers/HomeController'),
loading: Loading,
}),
exact: true,
},
...
];
This issue on SO is possibly related to the server error I'm seeing above, but provided even less info.
My .babelrc is already using @babel/plugin-syntax-dynamic-import, but I tried adding babel-plugin-dynamic-import-node. This fixes the server issue but Webpack then no longer builds the chunks.
I've been unable to find a definitive example to get this working. There is conflicting info out there about proper setup. For example, the react-loadable README says to use the included react-loadable/babel plugin, while this post by the lib author says to use babel-plugin-import-inspector. This PR seemed to be attempting to address Webpack 4 issues but was closed, and the forked lib appeared to have issues as well.
I am using:
Babel 7
Node 10.4
React 16.5
React-Loadable 5.5
Webpack 4
