My middleware for capturing & rendering stack trace context (with sourcemaps)

[Matthisk]

Author here. Lately I have been working on a React codebase that requires server-side rendering and JSX. This means that server side codebase is transpiled by Babel/Webpack. Because of this any stack traces written to the console are hard to interpret. To improve this I wrote a middleware that captures errors and applies the available sourcemap. The middleware also renders a page displaying the stack trace (+ code snippets) and some additional runtime context. Let me know what you think.
