@aws-sdk/client-ecr and @aws-sdk/client-s3 each pull in dozens of
@smithy/* and middleware-* transitive packages but only fire when an
operator configures an ECR registry or cloud backup respectively. Move
both to optionalDependencies so the package classification matches
their runtime role and operators who never use either feature can run
`npm ci --omit=optional` for a ~150 MB-slimmer image.
The default Dockerfile install (`npm ci --omit=dev`) keeps shipping
the SDKs, so default installs are unchanged. The dynamic imports in
CloudBackupService.loadS3Sdk and RegistryService.fetchEcrToken now
catch a missing-module failure and throw a wrapped Error whose
message names the recovery path (`reinstall without --omit=optional`)
and whose cause propagates the original module-not-found error for
debugging.
Bumps tsconfig.json's target and lib to ES2022 so `new Error(msg,
{ cause })` is typed; Node 25 already supports this at runtime.
@aws-sdk/client-s3 pulls in dozens of @smithy/* and middleware-*
transitive packages. Cloud backup is a Skipper+ opt-in feature and
the bulk of installs never configure it, but the eager top-level
import meant every cold start parsed the whole SDK regardless.
Wrap the import in a load-and-cache helper, make buildS3Client
async, and have it return both the S3Client and the SDK namespace
so each caller constructs commands from the same lazily-loaded
module. The pattern matches the existing dynamic import of
@aws-sdk/client-ecr in RegistryService and the lazy-loaded
composerize and isomorphic-git in PR #819.
Tests use vi.mock('@aws-sdk/client-s3', ...) returning named
exports, which works the same way for dynamic imports as it did
for the static ones.
* feat(cloud-backup): mirror fleet snapshots to S3-compatible storage
Add an Admiral-tier Cloud Backup feature that replicates every fleet
snapshot to off-site storage, with two provider modes that share the
same `@aws-sdk/client-s3` code path:
- Sencho Cloud Backup: zero-config, 500 MB allowance backed by
Cloudflare R2, provisioned via the sencho.io worker against the
user's Lemon Squeezy license.
- Custom S3 (BYOB): any S3-compatible bucket (AWS, MinIO, Backblaze
B2, Wasabi, R2 with own keys), with credentials encrypted via
`CryptoService` before storage.
API-triggered snapshots upload fire-and-forget so the UI returns
immediately; scheduled snapshots block on the upload so the task's
success/failure reflects cloud durability. Object keys include the
instance_id segment to prevent collisions when the same Admiral
license is activated on multiple Sencho instances.
* fix(cloud-backup): drop ES2022-only Error cause arg breaking ES2020 build
The backend tsconfig pins lib to ES2020. The two-argument
`Error(message, { cause })` form requires ES2022, so tsc rejected it
with TS2554. Revert to single-argument throw to match the
convention used elsewhere in the backend services.
