This is a fork of Create React App, intended for use at our company Code Yellow B.V.

The main differences with Create React App are;

• No CSS Autoprefixer, we only support modern browsers
• Uses cache-loader to cache Babel output
• Doesn't use source maps by default
• Support for PUBLIC_URL env variable in dev
• Allows module resolving from src/ (e.g. import 'components/foo' works everywhere)
• Uses Babel Minify instead of UglifyJs for minifying
• Basic Electron compatibility via env variable
• Allows custom dotenv file location (in our build system .env cannot live in the repository root)
• Includes env variables in frontend build with prefix CY_FRONTEND_* instead of REACT_APP_*
• It is allowed to use a custom .eslintrc file (CRA will ignore .eslintrc files by default)
• Babel preset:
  • Less transpiling (we don't have to support many browsers), but still possible to enable a little bit more transpiling via an env variable
  • Uses styled-components babel plugin
  • Uses decorator babel plugin

Getting Started
