refs https://github.com/TryGhost/Team/issues/1083 The Offers service is going to need access to the StripeAPIService too, so we need to move it out of the @tryghost/members-api module and make it accessible to both.

// The Ghost Boot Sequence
|
|
// -----------------------
|
|
// - This is intentionally one big file at the moment, so that we don't have to follow boot logic all over the place
|
|
// - This file is FULL of debug statements so we can see timings for the various steps because the boot needs to be as fast as possible
|
|
// - As we manage to break the codebase down into distinct components for e.g. the frontend, their boot logic can be offloaded to them
|
|
// - app.js is separate as the first example of each component having it's own app.js file colocated with it, instead of inside of server/web
|
|
//
|
|
// IMPORTANT:
|
|
// ----------
|
|
// The only global requires here should be overrides + debug so we can monitor timings with DEBUG = ghost: boot * node ghost
