no issue - we're no longer making use of the websockets experiment so it's just bloat - this is the whole feature in a single commit in case we need to revive it at some point

// 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
