Run locally

In-memory KV (no AWS required):

TELEGRAM_BOT_TOKEN=… \
TELEGRAM_WEBHOOK_SECRET=local \
PORT=8080 \
MODULES= \
go run ./cmd/server

End-to-end smoke test against a Telegram dev bot needs ngrok (local) or a deployed Function URL. The dev bot is created manually; token injected via env vars only.

For DynamoDB integration tests:

make dynamodb-local      # docker run amazon/dynamodb-local on :8001
make test-dynamodb       # runs internal/storage tests against DDB Local

Test

make vet              # go vet
make test             # full unit suite (no emulator)
make test-dynamodb    # storage tests against DynamoDB Local (requires Docker)

Deploy

First-time onboarding: see docs/deploy-aws-free-tier-guide.md.

Steady-state operations: docs/deploy-aws.md.

After the initial setup, every push to main triggers .github/workflows/deploy.yml (GitHub Actions OIDC → SAM deploy). No long-lived AWS keys.
