ReferenceError: regeneratorRuntime is not defined about query HOT 8 CLOSED

I'll double check the babel implementation, but it should be including all of that in the build.

from query.

Double checked and this should be fine as is. This is likely because you are compiling to a target that needs babel-polyfill.

I'm having the same issue. Here is my browserlistrc. Any suggestions on how to get this working?

here is my babel config

module.exports = function(api) {
  api.cache(true)

  const presets = [
    ['@babel/preset-env', { useBuiltIns: 'entry', corejs: 3 }],
    ['@babel/preset-react']
  ]

  const plugins = ['react-hot-loader/babel', 'babel-plugin-styled-components']

  return { presets, plugins }
}

relevant webpack section

  {
        test: /.(js|jsx)$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader'
        }
      },

from query.

My build is a webpack build using babel-loader with the preset used in CRA with Typescript enabled

Unfortunately it's a closed source app, but I'll take a stab at making a reproducible test case, I'll start with the example in this repo

Okay I think I see what the problem is. So I'm not using CRA but my own webpack.config.ts that is inspired by CRA but I don't have the react-app-polyfill stuff. I already have a polyfill.ts so I should be able to add the babel ones there

This comes everytime in nextjs projects. Heres the link to sandbox https://codesandbox.io/s/nifty-saha-s2k7d . Tried in local also same result.
