Cannot find module 'browserslist-config-single-spa'

This error comes up when building webpack apps that include single-spa-react. It's thrown from babel-loader. It was introduced in 4.5.0 - 4.4.0 works fine. I think that to fix it browserslist-config-single-spa should be moved from devDependencies to dependencies.

ERROR in ./node_modules/single-spa-react/lib/esm/single-spa-react.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: Cannot find module 'browserslist-config-single-spa'

I fixed it by setting a rule to load single-spa-react with ignorebrowserslistconfig option in babel-loader config. So it occurs when loading node_modules with babel-loader for transpilation. I remember it was the default config in create-react-app so it may be worth to fix it here as well.

Thanks for reporting this, I've created #137 to fix this.
