I know it s pretty late  but for future people stumbling upon this issue  if you want to have access to the webpack config of CRA  there s no other way except you have to run     npm run eject   However  with ejection  you ll strip away yourself from CRA pipeline of updates  therefore from the point of ejection  you have to maintain it yourself   I have come across this issue many times  and therefore I ve created a template for react apps which have most of the same config as CRA  but also additional perks  like styled-components  jest unit test  Travis ci for deployments  prettier  ESLint  etc     to make the maintenance easier  Check out the repo
