• Rollup Version: 1.31
• Operating System (or Browser): osx
• Node Version (if applicable): 12.10
• Link to reproduction (IMPORTANT, read below):
  [3.0-beta] Uncaught ReferenceError: require is not defined apollographql/apollo-client#6035

This is most probably due to this snippet of code in apollo-client:

export function requireReactLazily(): typeof import('react') {
  return React || (React = require('react'));
}

I am using plugin-commonjs/node-resolve.
Output format: esm

Expected Behavior

Rollup should bundle React along with apollo-client. And not fail during runtime.

Actual Behavior

App load fails with require is not defined error.
