[Solved]-React-Loadable SSR with Webpack 4 and Babel 7-Reactjs

I had the exact same problem today. After adding dynamic-import-node to the plugins of my .babelrc the server worked, but webpack wasn't creating the chunks. I then removed it again from my .babelrc and moved it to my server script with @babel/register. My server script now looks like this:

require( "@babel/register" )({
    presets: ["@babel/preset-env", "@babel/preset-react"],
    plugins: ["dynamic-import-node"]
});
require( "./src/server" );

I hope this helps ;)
