- 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
- Reduced our maintenance middleware code down to the bare minimum!
- We have an old maintenance middleware in place to handle when a site is forcibly put into maintenance mode, or the urlService hasn't finished booting
- This maintenance middleware was mounted on every sub app, instead of globally for reasons I no longer remember
- Recently, we introduced a new, static version of maintenence middleware to show during the boot process so we can get the server started earlier & not drop requests
- This version has its own HTML template and doesn't depend on any of Ghost's error rendering code
- To simplify and help with decoupling, this commit merges the two middleware, so that the new independent & static middleware renders its template for any one of the 3 possible maintenance modes
- It only needs to exist in the top level app 🙌
TODO: move the maintenance middleware to its own file/package so it's not part of the app.js as that is weird
- This is a minor bugbare, but it will affect some configuration I'm about to do for c8
- I've been wanting to do it for ages, middleware is plural all on it's own so it's an odd affectation in our codebase
- This also only exists in 2 places, everywhere else we use "middleware"
- Sadly it did result in a lot of churn as I did a full find and replace, but consistency is king!
