From Things nobody will tell you about React.js by Gianluca Guarini
The router decision was not as hard as deciding between mobx or redux because the React.js community seems to agree mainly on react-router. React-router is not officially maintained by facebook and the maintainers had the great idea of bumping 3 major versions in 5 months completely not backward compatible to each other so this means that all the tutorials and articles about how to use it didn’t keep up with the updates becoming useless if you are using the latest version of the library.
