Create React App is by default zero configuration and we do our best not to make it possible to break it. For example you cannot access the configurations of Webpack for this reason. We do allow some configuration through environment variables[0] but try to minimize amount of those too (and some of them will probably get removed in future version too). The public API is around 4 commands (start, build, test, eject).

This makes it possible to make big changes underneath the package in even minor versions (eg. updating major version of Webpack) without breaking existing CRA-powered apps. You can see migration guides for every single version in the Changelog, usually consisting running a single command[1]. This was also true for the major update from 1.x to 2.x [2]

That said, it does take some effort to understand the benefits and limitations of CRA. How could we improve on that one?
