feat(portal-shell): wire spa-side opentelemetry tracing (#72)
## Summary Phase 2 of ADR-0012 — closes the loop SPA → BFF → DB. After this PR, a single user action (initial page load, click, form submit) produces one trace whose root span is owned by the SPA and whose child spans cover the BFF request, Postgres queries through Prisma, and (eventually) Redis / downstream-API hops. ## What lands **Browser-side OTel libs** (production deps): - `@opentelemetry/sdk-trace-web` — browser tracer + provider - `@opentelemetry/exporter-trace-otlp-http` — OTLP/HTTP+JSON exporter - `@opentelemetry/instrumentation` — auto-instrumentation runtime - `@opentelemetry/instrumentation-fetch` — `fetch` + W3C `traceparent` propagation - `@opentelemetry/instrumentation-document-load` — initial-paint timings - `@opentelemetry/instrumentation-user-interaction` — click / keypress / submit No `@opentelemetry/context-zone`: the workspace is zoneless per ADR-0004; the default `StackContextManager` covers the auto-instrumented paths. Custom spans across `await` will need explicit `context.with(...)` plumbing — fine, encountered as code lands. **Code**: - [`apps/portal-shell/src/observability/tracing.ts`](apps/portal-shell/src/observability/tracing.ts) — `WebTracerProvider` bootstrap. Documents the load-order constraint inline (same pattern as the BFF: must be the very first import of `main.ts`, otherwise auto-instrumentations miss everything imported above). - `apps/portal-shell/src/main.ts` now imports the tracing module as line 1. **CORS plumbing** for end-to-end trace propagation: - BFF (`apps/portal-bff/src/main.ts`) calls `enableCors` with a minimal dev allowlist (`http://localhost:4200`) and explicit permission for the W3C `traceparent` / `tracestate` headers. The full security-grade CORS (per-environment allowlists, helmet, cookie-session, CSRF) belongs to the future phase-2 security ADR — this PR adds the strict minimum for the SPA→BFF trace context to survive cross-origin pre-flight. - OTel Collector (`infra/local/otel-collector.yaml`) gains a `cors` block on its OTLP/HTTP receiver so the browser's own OTLP POST clears its pre-flight. **ADR-0012 §Confirmation** rewritten: a new "Wired in the SPA foundation PR (phase 2)" block enumerates what landed here; the carry-over "Wired as features land" list drops the SPA-side SDK item and adds a follow-up note about the security-grade CORS. ## Verification ```bash pnpm exec nx run-many -t lint test build # 8 projects green pnpm audit # 0 vulns ./infra/local/dev.sh up observability # bring up Collector + Jaeger ./infra/local/dev.sh # (separately, BFF stack — your choice) pnpm nx serve portal-bff # localhost:3000 pnpm nx serve portal-shell # localhost:4200 ``` Open http://localhost:4200 → a `document_load` trace appears in http://localhost:16686 with `service.name=portal-shell`. From DevTools, run `fetch('http://localhost:3000/api/health').then(r => r.json())` → a fetch span appears with a child BFF span on the same trace. ## Test plan - [ ] CI green on this PR. - [ ] After local up, `document_load` span visible in Jaeger UI for the SPA. - [ ] Cross-origin fetch from SPA carries `traceparent` (visible in Network tab) and produces a single end-to-end trace SPA → BFF in Jaeger. - [ ] DevTools console shows no CORS warnings about `traceparent`, `tracestate`, or the `localhost:4318/v1/traces` POST. --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #72 |

chore: generate portal-shell and portal-bff apps per ADR-0004 / ADR-0005
Add the @nx/angular, @nx/nest, @nx/vite, @nx/eslint plugins, then generate the two apps. Adjust the empty-template tsconfig.base.json to be Angular-compatible (drop project references and customConditions that the empty-template defaults to but Angular doesn't support; keep the strict-TS extensions from ADR-0004). apps/portal-shell (Angular 21): - standalone APIs, routing, SCSS, esbuild - vitest-angular as unitTestRunner, playwright for e2e - strict mode - tags scope:portal-shell, type:app - app.config.ts wired with provideZonelessChangeDetection() per ADR-0004 (Angular 21 + Nx 22 generates without zone.js by default) apps/portal-bff (NestJS 11): - Express adapter (default per ADR-0005) - Jest as unitTestRunner - tags scope:portal-bff, type:app - main.ts wired with a global ValidationPipe configured whitelist + forbidNonWhitelisted + transform per ADR-0005 - Phase-2 security additions (helmet, CORS, sessions, CSRF, rate limit, auth guards, error filter) deferred to their respective ADRs - placeholder comment in main.ts Workspace dependencies: class-validator + class-transformer added (required by NestJS ValidationPipe at runtime). Nx-generated .gitignore additions (.angular, __screenshots__) merged into ours. .vscode/extensions.json and launch.json added by Nx are kept (do not override our existing settings.json). |
