* fix(jobs): survive Redis Cloud maintenance reconnects BullMQ duplicates ioredis connections without inheriting error listeners, so Redis Cloud maintenance (ECONNABORTED) crashed the API process. Attach error handlers on duplicates, harden reconnect options for failover, and add API process-level safety nets. Co-authored-by: Rotimi Best <rotimi-best@users.noreply.github.com> * refactor(jobs): address review feedback on Redis resilience fix - reconnectOnError returns 2 for READONLY/LOADING so the failed command is resent against the newly promoted primary after failover - export prepareRedisConnection and test the real implementation instead of a reimplemented copy; add a no-double-listener regression case - API uncaughtException now reports to Sentry and fails fast (flush + exit 1) so the orchestrator restarts cleanly instead of running in an undefined state Co-authored-by: Rotimi Best <rotimi-best@users.noreply.github.com> * fix(api): don't fail-fast on transient Redis errors in process guard End-to-end testing (restarting Redis to simulate Cloud maintenance) revealed node-redis surfaces reconnect failures as an uncaught AggregateError [ECONNREFUSED], which the fail-fast uncaughtException guard turned into a process exit. Classify transient Redis/socket errors (incl. AggregateError sub-errors) and log-and-continue for those; still fail fast on unknown errors. Co-authored-by: Rotimi Best <rotimi-best@users.noreply.github.com> * fix(api): address PR review on Redis process guards and logging - Fail fast on non-transient unhandledRejection (Greptile) - Filter Sentry OnUncaughtException/OnUnhandledRejection integrations to avoid double-capture; keep custom guards with transient Redis filtering - Make wrapDuplicate idempotent; throttle reconnect/error logs during maintenance - Drop READONLY/LOADING from node-redis transient classifier (command-level only) Co-authored-by: Rotimi Best <rotimi-best@users.noreply.github.com> * fix(api): rate-limit transient Redis warnings in process guards Reuse logTransientRedisEvent from core so maintenance bursts do not flood logs from uncaughtException/unhandledRejection handlers.

Getting Started
To get a local copy up and running, please follow these simple steps.
Prerequisites
Here is what you need to be able to run ClassroomIO.com
- Node.js (Version: >=20.19.3) — required
- pnpm (v10) — required; the package scripts call
pnpmdirectly, so npm/yarn are not substitutes - Docker — required; runs Postgres + Redis (no local install of those needed)
Project Structure
This repo is a monorepo that consists of these primary apps:
website: The landing page of ClassroomIO hosted hereapi: The api service that handles PDF, video processing, Emailing and Notifications.dashboard: The web application that runs the learning management system hosted here.docs: Official documentation of ClassroomIO hosted here
The repository also contains shared packages under packages/ (for example packages/db, packages/utils, and packages/ui).
Development
Local Setup
Before you start: make sure pnpm and Docker are installed (see Prerequisites). New to the project? Read
DEV_SETUP_NOTES.mdfirst — it's a full step-by-step walkthrough with a troubleshooting reference for the errors you're likely to hit.
-
Fork the repo, then clone it:
git clone https://github.com/classroomio/classroomio.git -
Go to project folder:
cd classroomio -
Set up Node (using
nvm):nvm useYou first might need to install the specific version and then use it:
nvm install && nvm useYou can install nvm from here.
-
Install dependencies:
pnpm i -
Set up your
.envfiles:Each app reads its own
.env. Inapps/api,apps/jobsandapps/dashboard, duplicate.env.exampleto.envand fill the values below (host ports). The secret values are placeholders — generate each one withopenssl rand -hex 32rather than copying the example text. The twoPRIVATE_SERVER_KEYvalues must match — they authenticate the dashboard's server-to-server calls to the API, so generate it once and paste the same value into both files.-
apps/api/.env:DATABASE_URL="postgresql://postgres:postgres@localhost:5432/classroomio" REDIS_URL="redis://localhost:6379" PUBLIC_SERVER_URL="http://localhost:3002" TRUSTED_ORIGINS="http://localhost:5173" # the dashboard dev origin BETTER_AUTH_SECRET="<generate-with-openssl-rand-hex-32>" PRIVATE_SERVER_KEY="<generate-with-openssl-rand-hex-32>" # generate once; use the SAME value in the dashboard DASHBOARD_ORIGIN="http://localhost:5173" # optional; used for invite/email links back to the dashboard -
apps/jobs/.env: The jobs service handles background tasks (emails, media processing, analytics rollups, etc.).Recommended setup (simplest):
cd apps/jobs ln -s ../../apps/api/.env .env -
apps/dashboard/.env:PUBLIC_SERVER_URL="http://localhost:3002" PRIVATE_SERVER_URL="http://localhost:3002" # used by the SSR auth proxy — required, or login returns "API upstream not configured" PRIVATE_SERVER_KEY="<generate-with-openssl-rand-hex-32>" # must match the API (paste the value generated above) PUBLIC_IS_SELFHOSTED=true -
Running the background workers? Also create
apps/jobs/.env(e.g.cp apps/api/.env apps/jobs/.env); it needsREDIS_URL. Thepackages/db/.envused by the DB scripts is set up in step 6. -
Optional for self-hosted Enterprise-only features (SSO, token-auth, no-tracking): set
LICENSE_KEYinapps/api/.env. -
Optional upload size limits: set matching
UPLOAD_MAX_*_MBvalues in bothapps/api/.envandapps/dashboard/.env(seeapps/api/.env.example). Defaults are 5 MB documents, 2 MB assignment files, 800 MB videos.
-
-
Start local infrastructure for API (Postgres + Redis) and seed the DB:
docker compose -f docker-compose.yaml up -d postgres redis cp packages/db/.env.example packages/db/.env # one-time (Windows: Copy-Item) pnpm --filter @cio/db db:setup:seed- Connect with
DATABASE_URL=postgresql://postgres:postgres@localhost:5432/classroomio - Connect with
REDIS_URL=redis://localhost:6379 db:setup:seedcreates the schema and seeds demo data once Postgres is up. The db scripts run with their own working directory, so they readDATABASE_URLfrompackages/db/.env(notapps/api/.env).
- Connect with
-
(Optional) Start MinIO locally for object storage (media/documents):
docker compose -f docker-compose.yaml --profile minio up -d minio minio-init- Console: http://localhost:9001 (user/pass default
minioadmin/minioadmin) - S3 endpoint: http://localhost:9000
- Buckets created by
minio-init:videos,documents,media - Add to
apps/api/.envwhen using MinIO locally:OBJECT_STORAGE_ENDPOINT=http://localhost:9000OBJECT_STORAGE_PUBLIC_ENDPOINT=http://localhost:9000OBJECT_STORAGE_ACCESS_KEY_ID=minioadminOBJECT_STORAGE_SECRET_ACCESS_KEY=minioadminOBJECT_STORAGE_FORCE_PATH_STYLE=trueOBJECT_STORAGE_MEDIA_PUBLIC_BASE_URL=http://localhost:9000/media
- Console: http://localhost:9001 (user/pass default
-
Run the local app services in separate terminals:
pnpm api:devpnpm dashboard:dev- If you see
Failed to resolve entry for package "@cio/...", the shared workspace packages haven't been built yet (theirdist/is missing). Build them once withpnpm build, then re-run the dev commands.
- If you see
-
Default local URLs:
api: http://localhost:3002dashboard: http://localhost:5173

Optional: run other apps:
- website:
pnpm website:dev - docs:
pnpm dev --filter=@cio/docs
-

Enabling the AI Course Assistant
The in-course AI chat (course authoring, plan generation, lesson edits) is disabled by default. Enable it by setting at least one provider API key in apps/api/.env (or the root .env for the Docker stack):
# Pick one or more — the dashboard model picker exposes Gemini 2.5 Flash and GPT-4o.
OPENAI_API_KEY=sk-... # enables GPT-4o
GOOGLE_API_KEY=AIza... # enables Gemini 2.5 Flash (default model in the picker)
ANTHROPIC_API_KEY=sk-ant-... # supported in code; not currently in the picker UI
Notes:
- The
GET /agent/statusendpoint flips toenabled: trueas soon as any of those keys is set, which is what the dashboard checks before showing the AI button on a course. - Each chat request sends the user-selected
model(persisted inlocalStorageasclassroomio-ai-chat-model). The API resolves the provider for that model (packages/utils/src/agent-models) and returns 503AI_NOT_CONFIGUREDif that provider's key is missing. - Optional Tinybird observability: set
TINYBIRD_TOKEN(and optionallyTINYBIRD_BASE_URL) inapps/api/.env. Events are silently skipped when the token is absent. - More detail on architecture, tools, and routes lives in
prd/ai-course-assistant [DONE]/README.md.
Docker Compose (Full Stack)
cp .env.example .env # copy env template, edit for your domain
./run-docker-full-stack.sh
The script reads root .env via docker compose --env-file .env and auto-generates a secure PRIVATE_SERVER_KEY (and BETTER_AUTH_SECRET) when missing.
See .env.example for the full list of environment variables with required/optional grouping, and docker/docs/SELF_HOST.md for the complete Docker self-hosting guide. To raise upload caps (documents, videos, assignment files), set the UPLOAD_MAX_*_MB vars in .env — see the docs.
Publishing
When cutting releases for hosted assets or the npm MCP package, run:
- Storybook —
pnpm --filter @cio/storybook storybook:publish - Course widget embed —
pnpm --filter @cio/embeds embeds:publish - Question type picker —
pnpm --filter @cio/embeds embeds:publish(same script builds and uploads both embeds) - MCP (
@classroomio/mcp) — bump the version inpackages/mcp/package.json, thenpnpm mcp:buildandpnpm --filter @classroomio/mcp publish
