Resolves several install pain points reported by users (#108, #120) and
removes the obligatory upstream-clone step that confused contributors and
slowed down every Docker build.
Install fixes:
- nginx: server_name → catch-all default_server, drop Debian's stock site
so reverse-proxied users no longer get the "Welcome to nginx" page.
- entrypoint: auto-generate SECRET_KEY at first boot, persisted under
data/.secret_key. backend/.env is now optional in docker-compose.yml.
- backend: add greenlet>=3.0.0 (SQLAlchemy async dep that was missing on
some Python builds — caused uvicorn startup failures on WSL).
Wokwi libs come from npm:
- @wokwi/elements 1.9.2, avr8js 0.21.0, rp2040js 1.3.2 are pinned in
frontend/package.json. Vite aliases removed.
- Dockerfile.standalone no longer clones avr8js / rp2040js / wokwi-elements
/ wokwi-boards. Frontend stage is just COPY + npm install + build:docker.
- Board SVGs vendored under frontend/public/boards/ (10 deduped against
existing files, 2 truly new). third-party/wokwi-* clones become reference-
only credits — generate-component-metadata.ts skips gracefully when absent.
Production config split out:
- docker-compose.prod.yml, deploy/nginx.prod.conf, nginx-host-velxio*.conf,
update-third-party.bat removed. Production deployment lives in its own
repo: https://github.com/velxio/velxio-prod (host nginx + HTTPS + backups
+ pinned upstream commit).
Verified locally: 1161 frontend tests pass, build:docker completes clean.

The directory grew well beyond Wokwi-only contents: it now hosts
lcgamboa's QEMU fork (qemu-lcgamboa), Espressif's esp32-camera, the
ngspice WASM build, fritzing-parts, picowi, an alternative QEMU
(qemu-esp32), the 100_Days_100_IoT_Projects examples repo, and
Wokwi's own avr8js/rp2040js/wokwi-elements/wokwi-features/wokwi-boards.
"wokwi-libs" was misleading — half the contents have nothing to do
with Wokwi. "third-party/" is the standard convention for vendored
external dependencies.
Mechanical changes:
Path rename:
wokwi-libs/ → third-party/
update-wokwi-libs.bat → update-third-party.bat
docs/WOKWI_LIBS.md → docs/THIRD_PARTY.md
Submodule reconfiguration:
.gitmodules — 4 path= and section names updated
.git/modules/wokwi-libs/ → .git/modules/third-party/
each submodule's .git file rewired to ../../.git/modules/third-party/<name>
Reference updates (~80 files): vite.config.ts aliases, Dockerfile
COPY paths, GH Actions workflow steps, build_qemu_*.sh, all
docs/* and test/*/autosearch/* entries that mention the path,
package-lock.json file: dependencies, .gitignore patterns,
sitemap.xml + index.html SEO blurbs, scripts/generate-component-*,
.dockerignore, .idea/vcs.xml. Bulk replaced both `wokwi-libs/`
(path) and bare `wokwi-libs` (textual mentions in docs/comments).
Verified:
- npx tsc -b --noEmit produces no new errors related to these paths
- vite.config.ts aliases now point at ../third-party/avr8js etc.
- All 4 git submodules (avr8js, rp2040js, wokwi-elements,
wokwi-features) are linked under third-party/ with their
worktrees re-populated and config files referencing the new path
- `grep -r wokwi-libs` returns zero hits outside node_modules,
.vite, frontend/dist, third-party/ (upstream submodule contents),
*.pyc caches, and *.dll.pre-camera rollback binaries

Track per-user, per-project, and per-board usage to inform pricing tier
decisions. Adds an admin dashboard with KPIs (DAU/WAU/MAU, totals,
success rate), time-series charts for compiles/runs, board family +
FQBN breakdowns, "board diversity" pie chart (key freemium signal),
top users/projects, and per-country breakdown via Cloudflare's
CF-IPCountry header. Admin can now also view private projects.
Backend:
- New UsageEvent table (append-only event log with user_id, project_id,
event_type, board_fqbn/family, country, error_kind, duration_ms)
- Aggregate counters on User (total_compiles/runs/errors, last_active,
signup_country, last_country) and Project (compile/run/update counts,
last_compiled/run timestamps) kept in sync by MetricsService for O(1)
dashboard reads
- 10 admin endpoints under /api/admin/metrics/{overview, timeseries,
boards, board-diversity, top-users, top-projects, countries,
users/{id}, projects/{id}}
- POST /api/metrics/run for client-side run telemetry
- Country detection via cf-ipcountry header (no DB / no API calls)
- Auto-migrations in lifespan for legacy DBs
Frontend:
- recharts-powered Dashboard tab with KPI cards and 4 charts
- New Boards tab with per-family + per-FQBN breakdown
- Country column with flag emoji on Users tab
- Top countries card on Dashboard
- compileCode now forwards project_id; Run button reports via WS
