Rotimi BestandRotimi Best fa060f5f6d feat(notifications): email notification preferences (#747)
* feat(notifications): add email notification preferences

Implement the email notification preferences PRD with org-level defaults
and personal opt-outs enforced at the email enqueue chokepoint.

- Add toggle map, profile.settings jsonb, and shouldSendEmail resolver
- Extend profile and organization update APIs with emailNotifications
- Pass preference context through all toggleable email send call sites
- Add Settings > Notifications page with personal and org admin sections

* feat(notifications): group email toggles into course, cohort, and enrollment sections

Organize personal and org notification settings into scannable sections
so users can find course- or cohort-related emails quickly.

* fix(notifications): use Exercise instead of Quiz in toggle copy

* fix(notifications): only mark certification email sent when enqueued

Skip setMemberCertificationEmailSent when notification preferences or
missing Redis prevent the completion email from being queued, so the
email can still send if preferences change later.

* fix(notifications): address PR review feedback

- Add EmailPreferenceLookupCache to avoid N+1 settings lookups in batch
  processors and multi-recipient email enqueue paths
- Replace $effect store hydration in notifications settings with onMount
  and explicit sync after save
- Remove thin api email-preferences re-export; import from db queries
- Hide tutor-only personal toggles (newStudent, newSubmission) for students

* fix(notifications): hydrate toggles after store load and add profile settings migration

- One-time store hydration via onMount plus guarded effect when profile/org
  load after mount, without clobbering in-progress edits
- Add drizzle migration for profile.settings jsonb column

ClassroomIO Backend

Supported Features

  1. Certificate download for students.
  2. Uploading videos to cloudflare (for storage) and Muse.ai (for transcription)

Running locally with video upload + playback

Lesson videos run through an HLS pipeline on Cloud. The browser encodes a 360/720/1080 ABR ladder with Mediabunny, uploads segments to R2 via presigned PUTs, and the player loads /hls/{assetId}/master.m3u8 from the API.

How /hls/* resolves depends on the environment:

URL the browser hits Who serves the bytes
Cloud production https://<tenant-host>/hls/... Cloudflare Worker (apps/tenant-router) — intercepts the path and streams directly from an R2 binding. Render is never in the bytestream.
Local dev / self-hosted ${PUBLIC_SERVER_URL}/hls/... (direct to API) Hono streaming route on the API — session-auth, then getS3Client().send(GetObjectCommand).

Self-hosted (PUBLIC_IS_SELFHOSTED=true) skips HLS entirely and falls back to raw-MP4 upload — no R2-specific code path. Everything below is for Cloud-style local development.

Required env

apps/api/.env:

# Object storage — Cloudflare R2 OR an S3-compatible local backend (MinIO, etc.)
CLOUDFLARE_ACCOUNT_ID=…
CLOUDFLARE_ACCESS_KEY=…
CLOUDFLARE_SECRET_ACCESS_KEY=…
# (or OBJECT_STORAGE_ENDPOINT / OBJECT_STORAGE_ACCESS_KEY_ID / OBJECT_STORAGE_SECRET_ACCESS_KEY)

# Optional — only needed if you want extract-audio → Whisper transcripts
OPENAI_API_KEY=…

# Optional — Redis enables the BullMQ media job pipeline. Without it the
# asset row is still created, but no transcription/thumbnail jobs run.
REDIS_URL=redis://localhost:6379

# Only required when you want to exercise the production cookie-mint path
# (`POST /organization/assets/:assetId/hls/cookie`). Locally the Hono /hls/*
# route uses session auth, so most of the time you can leave this unset.
# Same value must also be set as a Cloudflare secret on tenant-router for prod.
HLS_SIGNING_SECRET=…

apps/dashboard/.env:

# Already required by the existing API client — used as the HLS base URL too.
PUBLIC_SERVER_URL=http://localhost:3000

Run

pnpm --filter @cio/api dev
pnpm --filter @cio/dashboard dev
# (optional) pnpm --filter @cio/jobs dev  # for transcription + thumbnail jobs

Drop a video into a lesson; the dashboard encodes locally, you'll see segments arrive under videos/{assetId}/hls/… in R2 and an assets row with hls_manifest_key populated. Playback flows directly browser → API → R2 — no wrangler dev needed locally.

Production setup (one-time)

For Cloud deployment, generate the HMAC signing key the Worker uses to verify playback cookies and set it on both sides:

node -e "console.log(require('crypto').randomBytes(48).toString('base64url'))"
# On Render (apps/api service env):
HLS_SIGNING_SECRET=<paste>

# On Cloudflare (apps/tenant-router):
pnpm --filter @cio/tenant-router exec wrangler secret put HLS_SIGNING_SECRET
# paste the same value when prompted
