🎨 configurable logging with bunyan (#7431) - 🛠 add bunyan and prettyjson, remove morgan - ✨ add logging module - GhostLogger class that handles setup of bunyan - PrettyStream for stdout - ✨ config for logging - @TODO: testing level fatal? - ✨ log each request via GhostLogger (express middleware) - @TODO: add errors to output - 🔥 remove errors.updateActiveTheme - we can read the value from config - 🔥 remove 15 helper functions in core/server/errors/index.js - all these functions get replaced by modules: 1. logging 2. error middleware handling for html/json 3. error creation (which will be part of PR #7477) - ✨ add express error handler for html/json - one true error handler for express responses - contains still some TODO's, but they are not high priority for first implementation/integration - this middleware only takes responsibility of either rendering html responses or return json error responses - 🎨 use new express error handler in middleware/index - 404 and 500 handling - 🎨 return error instead of error message in permissions/index.js - the rule for error handling should be: if you call a unit, this unit should return a custom Ghost error - 🎨 wrap serve static module - rule: if you call a module/unit, you should always wrap this error - it's always the same rule - so the caller never has to worry about what comes back - it's always a clear error instance - in this case: we return our notfounderror if serve static does not find the resource - this avoid having checks everywhere - 🎨 replace usages of errors/index.js functions and adapt tests - use logging.error, logging.warn - make tests green - remove some usages of logging and throwing api errors -> because when a request is involved, logging happens automatically - 🐛 return errorDetails to Ghost-Admin - errorDetails is used for Theme error handling - 🎨 use 500er error for theme is missing error in theme-handler - 🎨 extend file rotation to 1w
