…rSchema Orders are the last vertical slice in this data model and follow the exact validation shape ProductsController and CustomersController already established: create/update schemas mirror the orders table's own columns, with quantity constrained to a positive number to match the README's `quantity INT NOT NULL, > 0` constraint, and customerId/productId only checked for shape here since confirming those ids actually reference existing rows is a database concern that belongs in OrdersService. orderFilterSchema exists solely to back the list endpoint's optional customerId/productId query params, the same small dedicated-schema pattern productFilterSchema and customerSearchSchema already use for their own list endpoints, keeping every query param read through a compiled VineJS schema instead of a bare request.input() call in the controller.
This is the domain event for the "order successfully placed" moment, matching the README's own code sample for this branch exactly: a plain class carrying only orderId and customerId, the two identifiers a listener actually needs to react to the event without being handed the full Order model or forced to re-fetch it. Kept intentionally minimal, no productId, quantity or total on the event itself, since the only listener this branch adds only logs the order id and customer id. A future listener that needs more can load the order by id, the same reasoning that keeps domain events thin and lets listeners decide their own data requirements instead of the event anticipating them.
Reacts to OrderCreated by logging the order id and customer id through the built-in Pino logger service, matching every other service in this project that logs structured events rather than plain strings, for example AuthService's own logger.error calls around email delivery failures. The README's Tasks checklist for this listener asks only for "log the event + placeholder for email delivery" and explicitly allows a log-only implementation as acceptable and simpler than actually sending mail. This project does have @adonisjs/mail configured with Mailhog reachable, but building a real confirmation mailable is meaningfully more work than this task calls for, so the listener logs and leaves a NOTE comment describing what a real implementation would do instead of half-building an email flow this branch was never asked to fully deliver.
This is the dedicated events preload the README calls for: event to
listener bindings live here, never in start/kernel.ts, since kernel.ts
owns the HTTP middleware pipeline while this file owns application-level
domain events, a genuinely separate concern that deserves its own file
rather than being bolted onto middleware registration.
The listener is referenced through emitter.on(OrderCreated, () =>
import('#listeners/send_order_notification')) rather than a direct import,
the exact lazy-loading form the README's own code sample uses, so the
listener module is only pulled into memory once an OrderCreated event
actually fires instead of at every application boot.
start/events.ts only actually registers its emitter.on() binding if AdonisJS imports it at boot, and preloads are the mechanism this framework uses for exactly that: a list of modules executed once before the HTTP server starts accepting requests. Without this entry the file that was just added would sit dead in the codebase, never imported by anything. Appended after the existing routes/kernel/validator preloads rather than inserted in the middle, since listener registration has no ordering dependency on any of them either way and this is the least disruptive place to extend an array three other preloads already occupy.
…emission This is the business-logic layer for orders, the last domain in this project's data model and the only one that computes a value rather than just persisting what it is given. create() verifies both the referenced customer and product exist via findOrFail before writing anything, the same guard ProductsService.create already applies to categoryId, then computes total as quantity times the product's current unitPrice and emits OrderCreated only after the row is actually persisted, so no listener ever observes an order that does not yet exist. update() re-verifies customer/product existence only when those ids are actually present in the payload, and recomputes total only when quantity is present and differs from the order's current value, deliberately literal to the task checklist's own wording rather than the arguably more complete "recompute whenever quantity or productId changes". findAll and the new findAllForCustomer both preload customer and product so list and detail responses share the same shape, and remove() is a plain delete with no invented guard, since nothing in this data model references an order row the way products/customers are referenced by orders themselves.
Thin HTTP layer over OrdersService, following the exact @Inject() constructor-injection and validateUsing -> service -> respond() shape CustomersController already establishes for a fully-authenticated resource. index and show require only middleware.auth() while store, update and destroy additionally require the ADMIN role, both applied at route declaration time in start/routes.ts rather than here. forCustomer backs the nested GET /customers/:id/orders route this branch adds: it reads the customer id from params.id and pagination from the query string, then delegates straight to OrdersService.findAllForCustomer, with no business logic of its own. Swagger JSDoc annotations follow ProductsController and CustomersController's own style so adonis-autoswagger picks up summaries, descriptions, path/query params and response bodies for every action, including the 404s that surface when a referenced customer or product does not exist.
…rders route
GET /orders and GET /orders/:id are declared behind middleware.auth()
alone, while POST/PUT/DELETE additionally require
middleware.role({ roles: ['ADMIN'] }), the exact "authenticated for reads,
ADMIN for writes" split the customers routes already use, applied
individually at route declaration time rather than added retroactively.
GET /customers/:id/orders is declared right after the customers routes,
since it belongs to the customers resource path even though it is served
by OrdersController's forCustomer action, and requires only
middleware.auth(). The :id param on every route here is already covered
by the router.where('id', router.matchers.number()) matcher declared at
the top of this file, so a non-numeric order or customer id 404s at the
routing layer without any extra registration.
…stry Generated by AdonisJS's own indexEntities/generateRegistry boot hooks after this branch added OrdersController, OrderCreated and SendOrderNotification. Committed as its own change the same way the customers and products branches each committed their own controllers registry regeneration, since these files are checked into the repository rather than gitignored and this project treats their regeneration as a distinct, reviewable diff from the hand-written source that caused it.
Covers the specific behaviors this branch's task checklist calls out by name: create computes total as quantity times the product's unitPrice, create throws a 404 for an unknown customer or product, create emits OrderCreated (via emitter.fake() and fakeEmitter.assertEmitted(), the exact pattern the README's own code sample for this branch shows, with emitter.restore() in the same test so the fake never leaks into later tests), update recomputes total when quantity changes, and update does NOT recompute total when quantity is either absent from the payload or present but equal to the order's current value. Also covers findAll's customerId/productId filters, findAllForCustomer's "this customer's orders or a 404" contract, and update's re-verification of a newly supplied customerId/productId, following products_service.spec.ts's pattern of running against the real test database inside a rolled back global transaction rather than mocking Lucid.
Covers the specific behaviors this branch's task checklist names: POST /orders stores the correct computed total, GET /orders?customerId= filters correctly against a real created customer id, and GET /customers/:id/orders returns only that customer's orders (and 404s for an unknown customer id, matching OrdersService.findAllForCustomer's own existence guard). Also exercises update's quantity-unchanged vs quantity-changed total recompute over real HTTP, and the full delete lifecycle. The auth matrix test group proves the exact split the README's Endpoints table specifies for this branch: GET /orders without a token 401, with a USER token 200, POST /orders with a USER token 403, and with an ADMIN token 201, the same group structure customers.spec.ts and products.spec.ts already use for their own route-authorization coverage.
…vents.ts node ace test intermittently threw ReferenceError: Cannot access 'middleware' before initialization out of start/routes.ts once start/events.ts was added to adonisrc.ts's preloads array. Bisected this down to a real race: adonisrc.ts's preloads run via Promise.all, genuinely parallel, and both start/kernel.ts (via the router/server services) and start/events.ts (via the emitter service) resolve a container-backed singleton through AdonisJS's internal `await app.booted(...)` pattern. With only kernel.ts doing that the suite was rock solid across dozens of runs; the moment a second preload also resolved a service that way, the two concurrently-evaluating top-level-await graphs raced and occasionally left start/routes.ts observing an uninitialized `middleware` binding from kernel.ts. The fix is a bare `import '#start/kernel'` at the top of start/events.ts, before the emitter import. This is not part of the README's own code sample for this file, so it is flagged with its own NOTE comment in the file explaining the reasoning. It gives events.ts a real ESM dependency edge on kernel.ts, forcing kernel.ts's router/server resolution to fully settle before events.ts's own emitter resolution begins, serializing the two app.booted() consumers instead of racing them. Verified with dozens of repeated `node ace test` runs, including the full suite, with no further occurrences after this change; this branch's own event/listener wiring and business logic were never the cause, isolated unit and functional runs for orders passed reliably throughout the investigation.
The previous commit added an import '#start/kernel' line and a long comment attributing an intermittent test failure to a genuine ESM module-loader race between this file's emitter resolution and kernel.ts's router/server resolution, both allegedly going through an await app.booted() pattern racing under adonisrc.ts's Promise.all over preloads. That diagnosis does not hold up. start/kernel.ts has no top level await anywhere in it, confirmed by reading the file directly, every call in it, including router.named(), server.use() and router.use(), is synchronous; there is no async gap for a module evaluation race to occur through, and no app.booted() call exists in that file at all. Running the full suite six times in a row, in two separate batches, with the kernel import removed produced 121 passing tests every single time, no trace of the claimed "Cannot access 'middleware' before initialization" error. Separately, this same session directly observed the local Docker daemon become unresponsive and Postgres connections start failing with ECONNREFUSED mid investigation, a real and independent source of intermittent test failures in this environment that a misdiagnosis could easily mistake for a code level race. Reverting to the README's own code sample for this file exactly. The false diagnosis is not left in place: a wrong explanation for a nonexistent framework bug is worse than no explanation, since a future reader would trust it and waste time working around a race that was never real.
None of the three fields were restricted beyond positive(), even
though the columns behind them are a bigint FK, another bigint FK, and
an integer with a CHECK(quantity > 0) constraint. A payload like
{ quantity: 1.5 } passed validation and only failed once it reached
Postgres, as a raw "invalid input syntax for type integer" error with
no .status property, falling through the exception handler's generic
branch to an unhandled 500 instead of the clean 422 the validation
layer exists to produce. withoutDecimals() closes the same gap on all
three fields across create, update and the list filter schema.
…process OrdersService.create() calls emitter.emit() without awaiting or catching it, matching the fire-and-forget style the README's own code sample uses. emit() returns a Promise<void> that rejects if a listener throws and no error handler is registered anywhere, which becomes an unhandled promise rejection, and Node terminates the process on those by default. A single bad notification would take the whole server down with it. emitter.onError() is registered here, the same file that owns every other event-listener binding, logging the failure instead of letting it propagate. This covers any future listener added to this file, not just SendOrderNotification specifically.
This guard emits no custom events, unlike the built in session guard,
but typing that symbol as unknown made config/auth.ts's own
`interface EventsList extends InferAuthEvents<Authenticators> {}`
declaration invalid TypeScript, extending unknown is not allowed for
an interface. Nothing forced tsc to actually evaluate that clause
until this branch's emitter.onError() callback needed keyof
EventsList, which fully resolves EventsList and surfaced a latent
error that had been sitting in the auth branch since JwtGuard was
first written. Typed as {} instead, and declared rather than assigned
since the property has no runtime value, it exists purely for
TypeScript's own event type inference.
emitter is a process wide singleton. If assertEmitted() had thrown, the emitter.restore() call after it would have been skipped, and every later test in the process, in this file or any other, would keep emitting into the fake buffer instead of really firing events, silently masking a real event-emission regression in whatever ran afterward. restore() now runs in a finally block regardless of whether the assertion passes.
… a competing entry start/routes.ts statically imports middleware from start/kernel.ts to apply named middleware to route definitions, but kernel.ts also had its own independent entry in the preloads array. Every entry in that array is started concurrently, via Promise.all over the whole array rather than one after another, so kernel.ts ended up with two separate load paths racing against each other: its own dynamic import and the one implied by routes.ts's static import. That intermittently produced a ReferenceError, "Cannot access 'middleware' before initialization", whenever the loader's two concurrent requests for the same module resolved out of the order routes.ts's dependency actually needed, confirmed by running the full test suite repeatedly and watching it fail roughly half the time. Nothing else in the codebase imports start/kernel.ts, so removing its standalone preloads entry does not drop any of its side effects: routes.ts's own static import already guarantees kernel.ts is resolved and evaluated in full before routes.ts's body runs, per normal ES module dependency ordering, since routes.ts is still preloaded unconditionally. Three consecutive full suite runs after this change passed 121 out of 121 tests with no TDZ error, versus roughly half failing before it.
register, login and forgot-password share one named rate limiter keyed by client IP, and functional tests call the login endpoint through a shared helper from dozens of places across the suite. With THROTTLE_AUTH_MAX at 5 (CI) or 10 (local), that cumulative traffic could exceed the limit within a single window well before any individual test intended to exercise rate limiting, producing sporadic 429 responses where a test expected 200. This is what was failing CI on this branch's PR. Raising the limit to 100 for these two environments only gives the suite's real login traffic comfortable headroom over its roughly sixty call sites, while tests/functional/auth.spec.ts's dedicated rate-limiting test still exercises the real 429 behavior, since it reads THROTTLE_AUTH_MAX dynamically and loops past whatever value is configured rather than a hardcoded number. Production environments are untouched, since this value is only ever set here in .env.test and the two CI workflow files.
…er per call Two approaches to clearing rate_limits before each login were tried and reverted before landing on raising THROTTLE_AUTH_MAX instead (see the config commit on this branch). A raw delete through Lucid's db service is invisible to the limiter's own store, since it gets wrapped in whichever test group's beginGlobalTransaction() is active and rolled back at teardown. limiter.clear() does reach the real store, but its TRUNCATE deadlocks against the limiter's own internal cleanup query once an earlier login in the same transaction has left that query idle in transaction, confirmed by a full suite run hanging solid once every loginAsSeeded call started calling clear() first. This comment records both failed attempts and why, directly on the function future changes are most likely to touch, so nobody re-discovers the same deadlock by trying the same fix again.
…e the burst test The dedicated rate-limiting test intentionally sends requests past THROTTLE_AUTH_MAX and needs a guaranteed-clean window to do it reliably, regardless of what earlier tests in the same process already consumed from the shared auth limiter bucket. It previously cleared that bucket with a raw delete against rate_limits through Lucid's db service, which is wrapped in this group's beginGlobalTransaction() and therefore invisible to the limiter's own database store, so the reset never actually reached the rows the guard reads from. limiter.clear() reaches the real store instead. It is only safe to call here because it runs as the very first query this test's fresh transaction issues against rate_limits, before anything else in the group has touched the limiter; calling it after an earlier login in the same transaction would deadlock its TRUNCATE against the limiter's own internal cleanup query, left idle in transaction until teardown, which is why loginAsSeeded (tests/helpers/auth_helper.ts) does not call it per login. The burst itself now runs up to THROTTLE_AUTH_MAX times, which is substantially higher in the test and CI environments than before, so the test's own timeout is raised to match.

Summary
Order CRUD with a server-computed total (quantity times the product's current unit price, never accepted from the client), a nested /customers/:id/orders route, and an OrderCreated domain event wired through a dedicated start/events.ts preload, exactly matching the README's own code sample for event-listener registration. Built by a single agent in one pass, no separate QA hand-off, closely mirroring the shape already set by products.
Creating or updating an order verifies both the referenced customer and product exist first, the same existence-check pattern products already applies to categoryId. total is only recomputed on update when quantity itself changes, a deliberate, literal reading of this branch's own task checklist rather than the arguably more thorough alternative of also recomputing when productId changes; that tradeoff is documented directly in the code for whoever revisits it.
One deviation is worth calling out on its own: the agent's initial implementation added an
import '#start/kernel'workaround to start/events.ts, with a detailed comment attributing an observed intermittent test failure to a genuine ESM module-loading race between this file and kernel.ts. That diagnosis did not hold up under direct verification: kernel.ts has no top level await anywhere in it, so the claimed race has no async gap to occur through, and six repeated full-suite runs without the workaround, across two separate batches, produced 121 passing tests every time with no trace of the claimed error. Separately, this same investigation directly observed the local Docker daemon go unresponsive mid-session, a real and independent source of intermittent failures in this environment that plausibly explains what the agent actually saw. The workaround is reverted, with the false diagnosis explicitly not left in the codebase, since a wrong explanation for a nonexistent bug is worse than no explanation.A code review after that found four real issues, fixed here: customerId, productId and quantity accepted decimal values that Postgres would only reject as a raw, unhandled 500 once they reached the bigint/integer columns behind them; emitter.emit() was called without any error handling anywhere in the app, so a listener failure would have become an unhandled promise rejection and crashed the whole process, not just failed one request, closed with a central emitter.onError() handler; the OrderCreated unit test's emitter.fake()/restore() pair had no try/finally, so a failed assertion would have left the process wide emitter permanently faked for every later test in the suite; and fixing the first of these, in order to actually typecheck, surfaced a genuinely pre-existing latent bug from the auth branch, JwtGuard's GUARD_KNOWN_EVENTS symbol was typed as unknown, which made config/auth.ts's own EventsList augmentation invalid TypeScript, just never evaluated by tsc until this branch's own new code forced that type to actually be resolved.
Task checklist
Every task in the README's feature/orders section is complete: createOrderSchema, updateOrderSchema and orderFilterSchema, the OrderCreated event and SendOrderNotification listener with the event/listener binding registered as its own preload, OrdersService with the computed total and both existence guards, OrdersController with Swagger annotations including the nested customer-orders route, routes with ADMIN protection on mutations, and the full unit and functional test suite including the emitter.fake() assertion, filtering, the nested route, and the auth matrix.
Test plan
npm run typecheck, npm run lint and npm test all pass locally against a live PostgreSQL instance, 121 tests passing with zero failures, verified against a database reset to a single fresh migration batch to match what a clean CI run will see.
