💥 Breaking changes (for pre-existing apps)
@babel/polyfilldoesn't make it possible to provide a smooth migration path fromcore-js@2tocore-js@3: for this reason, it was decided to deprecate@babel/polyfillin favor of separate inclusion of required parts ofcore-jsandregenerator-runtime. #2031
In each of your
/packs/*.jsfiles, change this:import "@babel/polyfill";to this:
import "core-js/stable"; import "regenerator-runtime/runtime";Don't forget install those dependencies directly!
yarn add --save core-js regenerator-runtime
