Ghost/core/server/web/api/middleware/version-match.js
Hannah Wolfe 829e8ed010 Expanded requires of lib/common i18n and events
- Having these as destructured from the same package is hindering refactoring now
- Events should really only ever be used server-side
- i18n should be a shared module for now so it can be used everywhere until we figure out something better
- Having them seperate also allows us to lint them properly
