First of the five domain-split PRs in docs/website/API_V2_PLAN.md § Phase 2. Pure
mechanical re-wiring: routes move between files, no handler, gate, validator or
annotation changes, and not one URL moves.
New src/router/v1/admin/index.js owns the two things the group shares — the
`noindex, isLoggedIn, staffOnly` gate and the mount table — and declares no routes
itself. The gate sits ahead of every mount so a capability router extracted in a
later PR cannot silently ship without it. Four capability routers mount at the
prefix they already owned inside the monolith:
account.router.js 6 routes -> /admin/account (self-service, no adminOnly)
users.router.js 15 routes -> /admin/users (adminOnly, router-level)
invites.router.js 3 routes -> /admin/invites (adminOnly, per-route)
authProviders.router.js 4 routes -> /admin/auth (adminOnly, per-route)
admin.routes.js keeps the other 82 (6+15+3+4+82 = the 110 inventoried admin
routes) and is mounted last at the group root; none of the four prefixes appears
in it, so nothing depends on mount ordering. It disappears when PR 5 lands.
Handlers still live in admin.controller.js and usersShard.controller.js — this
re-wires routes, not logic. `adminOnly` moves with the routes that use it, and
`usersRouter.use(adminOnly)` is exactly equivalent to the old
`adminRouter.use('/users', adminOnly)` now that the router is mounted at /users.
All three generated gates are zero-diff:
routes.manifest.json unchanged (200 public + 2 internal)
routes.guards.json unchanged — no route lost or gained a gate
swagger-output.json unchanged, byte-for-byte
The spec staying byte-identical depends on the path normalization landed in the
preceding commit; without it the four collection routes would have documented as
/api/v1/admin/{users,invites,account}/ with a trailing slash.
Server tests green (434/434).
