What

Every API handler with its own storage now has a test setup and the same three tests:

Handler Test setup CI group
api-event-handler-aws-ddb already had one DDB
api-event-handler-aws-ddb-os new (dynalite + OpenSearch) DDB+OS
api-event-handler-standalone-sql new (the SQL presets: SQLite in memory, or PGlite) SQL, PGlite

The tests, per handler:

  • freshInstall.test.ts boots the handler on an empty database and checks that the GraphQL schema builds. aws-ddb already had this one.
  • installation.test.ts installs the system the way the admin installation wizard does. The system reports not installed, installSystem runs every app installer and succeeds, the system then reports installed, and a second install fails with SYSTEM_ALREADY_INSTALLED. On standalone-sql the install also creates a self-hosted admin user, and the test logs in as that user and reads it back with getCurrentUser. The AWS handlers install without an admin user because Cognito needs a real user pool.
  • rootStorageDecorators.test.ts checks that a decorator an extension registers per request reaches the ACO, audit logs and websockets storage that the handler registers in the root container. On DDB that storage is registered as factories. On SQL, ACO and audit logs are instances and websockets is a transient class, so the SQL test covers registration paths the DDB one doesn't.

standalone-sql boots the real Node server on a random port and talks to it over HTTP. The server arms timers on start (scheduler recovery, the periodic empty-trash-bin call), so the test fakes timers while the server starts, which keeps those timers from firing.

One source change

@webiny/project: AdminExtension and ApiExtension imported defineExtension through extensions/index.ts, which imports them back. Native ESM tolerates that cycle. Vitest's module runner doesn't, so loading @webiny/self-hosted-auth in a test failed with defineExtension is not a function. Both files now import from ~/defineExtension/index.js, like every other extension file.

Not covered

api-event-handler-core and api-event-handler-standalone are storage-agnostic bases. They can't boot or install without a storage variant, and the three handlers above exercise them.

Checks

  • All tests pass locally: aws-ddb on DDB (7 tests), aws-ddb-os against OpenSearch 3.3.2 in Docker, standalone-sql on SQLite and on PGlite.
  • With @webiny/di patched to take decorators only from the registering container (the 1.x rule), the aws-ddb-os and standalone-sql decorator tests fail with [false, false, false]. Swapping in di 1.1.0 no longer works for this check, since the code now uses inContainerScope().
  • yarn check:test:types passes for all three packages. It also flagged two stale dbTable options in the existing aws-ddb tests (the handler config dropped it in chore: remove dead createServerWebsockets + dbTable config #5404), which this PR removes.
  • Build, adio, format, lint and sync-dependencies are clean.

Summary by CodeRabbit

  • Reliability
    • Expanded checks for fresh setup, installation status, repeat-install handling, and administrator sign-in across API deployment options.
    • Added checks that storage extensions are applied consistently across supported storage types.
  • Compatibility
    • Updated project configuration to support validation across API and storage combinations.

No direct changes to end-user functionality are described in this release.

…it logs and websockets storage

These three storages are registered in the root container as factories, and
extensions register per request. On @webiny/di 1.x, decorators came only from
the container that held the registration, so an extension's decorator never
reached them. @webiny/di 2.0 collects decorators from the resolving container
for factory, instance and transient registrations, which fixes this without
any change to the storages.

The test sends a request through the real DDB handler with an extension that
decorates all three and checks every resolved storage is decorated. It fails
on @webiny/di 1.1.0 and passes on 2.0.

Project Extension Imports

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Other

Merge Risk: 🔵 Low · up to 0141f

This change adds integration tests for the API handler packages and makes a small import fix in project extensions. Production behavior is unaffected. A minor test-teardown race in the SQL server helper is still open and could occasionally delay test cleanup, so it is worth fixing but should not block the merge.

… handler

api-event-handler-aws-ddb-os and api-event-handler-standalone-sql get a
test setup (DDB+OS and SQL CI groups). All three handlers now have a
boot test, an installation test and the root storage decorator test.

@webiny/project: AdminExtension and ApiExtension imported
defineExtension through extensions/index.ts, which imports them back.
Native ESM tolerates the cycle, vitest's module runner does not, so the
standalone SQL handler could not be loaded in a test. They now import
from ~/defineExtension/index.js like the other extensions.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Stop accepting connections before closing existing connections.

If a connection arrives between closeAllConnections() and close(), the first call cannot close it. The close callback can then wait for that connection and delay test teardown. Start server.close() before calling server.closeAllConnections(), then await the close callback. Node documents this order to avoid the race. (nodejs.org)

House style in the new tests: casts in their own const, no nested call
arguments, one import per line, block comments for multi-line comments.

yarn check:test:types now passes for the three handlers. The storage
probe no longer casts to never (createDecorator rejected its arguments),
createServer passes extensions without spreading an unknown, and the
aws-ddb tests drop the dbTable option the handler config lost in #5404.
