- This new HTMLErrorRenderer is borrowed heavily from finalHandler
- This is the module that express uses to render errors if there is no custom errorhandler
- It just renders a really simple html page wrapping err.stack in a <pre>
- This results in a nicely formatted, but unstyled error page
- I also updated BasicErrorRenderer to use the same res.statusCode + err.stack pattern rather than err.message
Note: This error renderer is _only_ used for renderering errors on the `/ghost/` route
- In almost all cases, errors here are rendered by Ember
- The only error that can be rendered here is a missing template error see: 2af9e2e12
