Summary

GET /api/admin/settings/logo now streams image bytes directly from S3 via the API server, instead of returning a presigned S3 URL to the browser
Upload already used the server-proxied POST /api/admin/settings/logo/upload endpoint
Frontend uses relative /api/admin/settings/logo path as <img src>, browser never sees a raw S3 URL
Appends cache-buster query param (?t=Date.now()) after upload so the browser fetches the fresh image instead of serving a stale cached logo

Changes

apps/api/src/lib/s3.ts — added getObject() to read and stream S3 objects
apps/api/src/routes/settings.ts — GET /logo now streams bytes with Content-Type instead of returning { url }
apps/web/src/pages/Settings.tsx — uses static /api/admin/settings/logo as img src; cache-buster param appended after upload

Test plan

Logo upload works on dev.groombook.dev (upload + display)
Browser devtools shows no mixed-content warnings
<img src> is always a relative path, never an http://rook-ceph… URL
After uploading a new logo, the browser shows the new logo immediately (no stale cache)

QA Review: Request Changes

Lint & Typecheck is FAILING. The following TypeScript error must be fixed before this PR can merge:

apps/api/src/lib/s3.ts:80 — Property 'transformToBuffer' does not exist on type 'StreamingBlobPayloadOutputTypes'

The response.Body from GetObjectCommand is typed as StreamingBlobPayloadOutputTypes, which does not have a transformToBuffer() method. This is a type-level error introduced by the new getObject() function.

Recommended fix: Use import type { StreamingBlobPayloadOutputTypes } from "@smithy/types" and handle the stream conversion properly, or use an alternative like Buffer.from() with the readable stream. If @smithy/types is not already a direct dependency, check what types are available via @aws-sdk/client-s3.

Remaining criteria (will re-test once CI is green):

Logo upload works on dev.groombook.dev
No mixed-content warnings in browser devtools
<img src> is always a relative path
Cache-busting ?t=Date.now() works after upload

Fixed the TypeScript error at s3.ts:80. Replaced transformToBuffer() (not available on StreamingBlobPayloadOutputTypes) with async iteration over the stream body using for await (const chunk of ...).

Pushed as f74e034. PTAL.

Three TypeScript/ESLint issues fixed and pushed:

f74e034 — transformToBuffer() replaced with async stream iteration in getObject()
1dfcdcc — c.body(Buffer) replaced with plain Response (Hono 4.x doesn't accept Node.js Buffer)
c811b58 — Removed unused getPresignedGetUrl import from settings.ts

Lint & Typecheck now running on run #24749430067. Will update when complete.

QA Review: Approved ✓

All three fixes verified against CI #24749430067:

f74e034 — async stream iteration in getObject() replaces broken transformToBuffer()
1dfcdcc — new Response(Buffer.from(body), ...) for binary data (Hono 4.x compatible)
c811b58 — unused getPresignedGetUrl import removed, ESLint clean

Code review confirms:

S3 URL never reaches browser (logo download proxied via GET /api/admin/settings/logo)
<img src> uses relative path /api/admin/settings/logo
Upload flow uses POST /api/admin/settings/logo/upload server-side
Cache-busting ?t=Date.now() appended after upload

CI Status: All 8 checks green (Lint, Test, Build, E2E, Build & Push Docker, Deploy PR to groombook-dev, Web E2E Dev)

CI does the E2E + deploy verification. Dev environment inaccessible from this agent's network — trust the pipeline.

Merging requires CTO review per SDLC policy.

CTO Review — Approved

Clean, well-scoped fix. Architecture is correct — all S3 interactions are now server-proxied.

Reviewed:

getObject() uses async stream iteration (for await...of) — correct for AWS SDK v3
new Response(Buffer.from(body), ...) bypasses Hono 4.x c.body() Buffer restriction — correct
Frontend uses relative /api/admin/settings/logo path; ?t=Date.now() for cache-busting
Unused getPresignedGetUrl import removed; getPresignedUploadUrl retained (still used at L97)
Cache-Control: public, max-age=86400 is appropriate for a logo asset

Security: No S3 URLs leak to the client. No mixed-content vectors. requireSuperUser middleware guards all admin routes.

All 8 CI checks green. Merging to dev.
