Skriptoteket Local Devops

Local development (canonical)

Hard rules

• Do not run docker compose up in this repo unless the user explicitly requests it.
• Run the backend via pdm run dev (host uvicorn), not via Compose.

PDM script map (most used)

• Backend:
  • pdm run dev / pdm run dev-logs (logs to .artifacts/dev-backend.log)
  • pdm run dev-local (backend + SPA with log piping)
  • pdm run kill-dev (kills host uvicorn; only when requested)
• Frontend (SPA):
  • pdm run fe-install
  • pdm run fe-dev / pdm run fe-dev-logs (logs to .artifacts/dev-frontend.log)
  • pdm run fe-build
• Quality gates:
  • pdm run format / pdm run lint / pdm run typecheck / pdm run test
  • pdm run docs-validate

Quick start checklist (backend)

1. Ensure .env exists (copy from .env.example).
2. Ensure tool artifacts directory exists and is configured:
   • Set ARTIFACTS_ROOT=/tmp/skriptoteket/artifacts in .env
   • Run mkdir -p /tmp/skriptoteket/artifacts
3. Install Python deps:
   • pdm install -G monorepo-tools
   • If you need browser tooling locally: pdm install -G monorepo-tools -G dev
4. Run backend:
   • pdm run dev

Quick start checklist (frontend SPA)

• Install deps: pdm run fe-install
• Run SPA dev server: pdm run fe-dev
• When debugging API calls, check backend logs from the pdm run dev terminal (Vite proxies to 127.0.0.1:8000).

Docker / containers (only when requested)

• DB-only dev:
  • docker compose up -d db
  • pdm run db-upgrade
• Full dev containers (long-running; don’t stop unless asked):
  • pdm run dev-start / pdm run dev-stop
  • Logs: pdm run dev-containers-logs
• Destructive resets (explicit approval required):
  • pdm run dev-db-reset

Verification (local)

• Health: curl -sSf http://127.0.0.1:8000/healthz >/dev/null
• Tokenizer availability (Devstral/Tekken): pdm run pytest -q tests/unit/infrastructure/llm/test_token_counter_resolver.py

Logging + correlation (local)

• Configure via .env:
  • LOG_FORMAT=json|console (default: json)
  • LOG_LEVEL=INFO|DEBUG|...
  • SERVICE_NAME / ENVIRONMENT (defaults: skriptoteket / development)
• For greppable backend logs: pdm run dev-logs (writes .artifacts/dev-backend.log)
• Verify correlation end-to-end (access logs + app logs):
  • curl -s -D - -o /dev/null -H 'X-Correlation-ID: <uuid>' http://127.0.0.1:8000/healthz
  • rg '<uuid>' .artifacts/dev-backend.log (expects a uvicorn.access JSON line with correlation_id)
• Note: in our pinned Uvicorn (0.40.0), uvicorn.access is emitted on http.response.start (headers sent), so SSE/streaming logs appear when the stream begins.
• If running the backend via container (only when requested), use: docker logs -f skriptoteket_web | rg '<uuid>'

PDM groups/extras (avoid rebuild surprises)

Mental model

• [project].dependencies is always installed (prod + local).
• [dependency-groups] is for dev-only groups (lint/test/dev tooling). These are selected with pdm install -G <group> (and are incompatible with --prod).
• [project.optional-dependencies] is for extras (runtime feature toggles). These are selected with pdm install --prod -G <extra> in production-like installs.

Known pitfall

• pdm install --prod -G <dependency-group> fails with: --prod is not allowed with dev groups.
  • Fix by moving that group to [project.optional-dependencies] if it must be selectable in prod builds, or by removing --prod if it’s dev-only.
