What is react-error-overlay-razzle-bug?

This is a bug report repository documenting a problem with how React displays error messages in development mode when using a tool called Razzle. When you're building a React application, the framework includes a helpful feature called "error overlay", a visual popup that appears in your browser whenever your code crashes. Instead of just seeing a blank screen or cryptic browser console errors, this overlay shows you exactly what went wrong and where in your code the problem occurred. It's one of React's most useful developer tools. The issue documented here is that this error overlay stops working when you're using Razzle, a framework that simplifies setting up and running React projects. The person who created this repo discovered that even when their code has a runtime error, the overlay doesn't appear. To reproduce the problem, you clone the repository, start the development server, navigate to the local website, and look for the error notification, but it doesn't show up, which makes debugging much harder. This is primarily useful for React developers who work with Razzle and encounter this specific bug. If you're in that situation, you'd want to look at this repo to understand what's happening and potentially find a workaround or fix. The three-star count suggests it's a niche issue that hasn't become widely documented yet, so this serves as a reference point for anyone hitting the same problem. The README doesn't include much detail about the root cause or proposed solutions, it's mainly a minimal reproduction case. That actually makes it quite useful: anyone experiencing the same problem can follow the exact steps to confirm they have the same issue, which is often the first step in getting a bug fixed.
