Cloud Development Environment

Services overview

Main app (apps/web): Next.js 16 app (Turbopack). Runs on port 3000.
PostgreSQL 16: Primary database. Runs on port 5432 via docker-compose.dev.yml.
Redis 7 + serverless-redis-http: Caching/rate-limiting. Redis on port 6380, HTTP proxy on port 8079.

Starting services

Start Docker daemon if needed: sudo dockerd &>/dev/null &, then confirm with docker info (or sudo docker info if the client cannot reach the daemon yet).
Start databases from repo root: docker compose -f docker-compose.dev.yml up -d. If you get permission denied on /var/run/docker.sock, run the same command with sudo docker compose instead of making the socket world-writable.
Run Prisma migrations: cd apps/web && pnpm prisma:migrate:local (uses dotenv -e .env.local; do NOT use bare prisma migrate dev — it won't load .env.local).
Start dev server: pnpm dev from repo root.

Environment file

The app reads apps/web/.env.local. Required non-obvious env vars beyond .env.example defaults:

DEFAULT_LLMS (e.g. openai:gpt-5.4-mini) — app crashes at startup without this.
GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET — hard-required by env.ts validation. Use Google emulator credentials for local dev (see below).
UPSTASH_REDIS_TOKEN must be set to dev_token to match the SRH_TOKEN default in docker-compose.dev.yml.
MICROSOFT_WEBHOOK_CLIENT_STATE — required if MICROSOFT_CLIENT_ID is set.

Google emulator for local dev

Use the Google emulator instead of real OAuth credentials:

GOOGLE_CLIENT_ID=emulate-google-client.apps.googleusercontent.com
GOOGLE_CLIENT_SECRET=emulate-google-secret
GOOGLE_BASE_URL=http://localhost:4002

Start the emulator: docker compose -f docker-compose.dev.yml --profile google-emulator up -d.

Testing

pnpm test runs Vitest unit/integration tests (no DB or external services required).
pnpm lint runs Biome. Pre-existing lint warnings/errors in the repo are expected.
AI tests (pnpm test-ai) require a real LLM API key and are skipped by default.

Docker in this environment

The cloud VM is a Docker-in-Docker setup. Docker requires fuse-overlayfs storage driver and iptables-legacy. These are configured during initial setup. After snapshot restore, run sudo dockerd &>/dev/null & if Docker daemon is not running.

The VM may not have the Docker Compose v2 plugin pre-installed. If docker compose version fails, install it:

sudo mkdir -p /usr/local/lib/docker/cli-plugins
sudo curl -fsSL https://github.com/docker/compose/releases/download/v2.29.2/docker-compose-linux-x86_64 -o /usr/local/lib/docker/cli-plugins/docker-compose
sudo chmod +x /usr/local/lib/docker/cli-plugins/docker-compose

Onboarding flow

After a fresh login via the Google emulator, the app forces an onboarding wizard. Some onboarding buttons require JavaScript click() calls rather than standard browser clicks (React event delegation quirk in headless/automation contexts).
