no issue
- right now, we mount all API endpoints (v2, v3 and canary), alongside some
other routes, when Ghost is booting. This is wasteful because we don't
necessarily need any of the endpoints to get Ghost up and running
- even when Admin is used, it uses `canary` so `v2` and `v3` sit in memory
- the better approach here is to lazy load these endpoints, so they only
get mounted when needed
- this commit adds the `lazyUse` function into our Express lib,
which takes a mount path and a module function to execute down the
line. This gets passed to the wonderful `express-lazy-router` lib which
detects when we're calling an unmounted module and will mount it for
us
- from local testing, this speeds up boot time by about 18% and reduces
initial memory usage by about 6% 🚀
- This stops the mounting of the admin and frontend from being buried deep in express initialisation
- Instead it's explicit, which makes two things almost possible:
1. we can potentially boot the frontend or backend independently
2. we can pass services and settings loaded during boot into the frontend
- This needs more work, but we can start to group all the frontend code together
- Meanwhile we also need to rip apart the routing and url services to decouple the frontend from the backend fully
- BABY STEPS!
- Makes the logic for determining the admin and frontend vhost args independent and easier to test
- Moved the tests to specifically test the vhost utils & removed proxyquire as a dependency
- We want to breakdown the current parent app into the existing core/app.js and boot code, allowing us to decouple the backend and frontend further
- This is all part of the refactoring to separate server and frontend completely
