Looks like this is an alternative to #4. |
|
Note to self, write test to check what happens if we have no error handling middleware. |

@tomdale Updated test cases to include testing error propagation when there is no custom error handling middleware. Can you double check the cases for accuracy? I'm happy to add any more that you can think of as well. |

Should we res.status here instead, so that middleware can alter the response, instead of being forced to deal with sendStatus

@danmcclain @tomdale Look it over one more time? |

| if (error.name !== "UnrecognizedURLError") { | ||
| res.status(500); |

Do we even need to do this? Or would the default handler do this?

I think we should set 500 because that accurately reflects the state of the request when it leaves the FastBoot middleware.
If post-FastBoot middleware wants to change the status code and attempt recovery it can. But that doesn't change the fact that our middleware resulted in an internal server error (i.e., a 500).

@arjansingh That rationale sounds reasonable to me.

Thanks @arjansingh 👏 |
