"I've heard from several people that they've consolidated their companies tool dependencies into a single package and this worked really well for them." - @dan_abramov
My team did this year ago. 100+ packages, build, lint, test config in 1 package!👍

We branded it "Fusion". Fusion is an opinionated way to do React dev at our company. It's a fork of create-react-app with many tweaks and enhancements. We regularly pull in changes from create-react-app to stay in sync.
We've added:
- Mock APIs
- Reusable component library
- Enhanced testing config for Cypress
- Custom linting rules that enforce our standards
- Sass support with theming
create-react-app is 🔥, but lots of ways to enhance it for your own needs.
