React Hot Loader 3 is on the horizon, and you can try it today (boilerplate branch, upgrade example). It fixes some long-standing issues with both React Hot Loader and React Transform, and is intended as a replacement for both. The docs are not there yet, but they will be added before the final release. For now, this commit is a good reference. This is highly experimental tech. If you’re enthusiastic about hot reloading, by all means, give it a try, but don’t bet your project on it. Either of the technologies it relies upon may change drastically or get deprecated any day. You’ve been warned 😉 .
