Usage Outside of cra-universal

If you want to use this Babel preset in a project not built with cra-universal, you can install it with following steps.

First, install Babel.

Then create a file named .babelrc with following contents in the root folder of your project:

{
  "presets": ["cra-universal", "@babel/preset-env", "@babel/preset-react"],
  "plugins": [
    "dynamic-import-node",
    "@babel/plugin-proposal-object-rest-spread",
    "@babel/plugin-proposal-class-properties"
  ]
}

This preset uses the useBuiltIns option with transform-object-rest-spread, which assumes that Object.assign is available or polyfilled.
