# Demo script
|
|
|
|
A running log of demoable outcomes, one section per slice. Each entry is a short,
|
|
copy-pasteable walkthrough against a local `make up` stack.

## S-07 — BFF: the portals' single backend
|
|
|
|
**Outcome:** the BFF validates Keycloak `digid` tokens on the self-service submit (forwarding the
|
|
bsn to the domain) and serves the openbaar register anonymously with only public-safe fields — the
|
|
front door the portals (S-08/S-09) will talk to.
|
|
|
|
**The path:** portal → BFF `POST /self-service/registrations` (token-gated) → domain; and
|
|
BFF `GET /openbaar/register` (anonymous) → projection-api. See ADR-0010.
|
|
|
|
```bash
|
|
# 1. Bring the full stack up.
|
|
make up
|
|
|
|
# 2. Drive the BFF end-to-end (401 without a token, 202 with a real digid token, anonymous openbaar).
|
|
make verify-bff # → "OK — BFF: 401 without token, 202 with a digid token, anonymous ..."
|
|
|
|
# 3. Try it by hand (BFF on host port 8080).
|
|
# a) A digid access token for the mock user jan-burger (bsn 123456782):
|
|
tok=$(curl -s -X POST http://localhost:8180/realms/digid/protocol/openid-connect/token \
|
|
-d grant_type=password -d client_id=big-portal -d username=jan-burger -d password=test123 \
|
|
| python3 -c "import sys,json;print(json.load(sys.stdin)['access_token'])")
|
|
|
|
# b) Submit — without the token it is 401; with it, 202:
|
|
curl -s -o /dev/null -w "no token -> %{http_code}\n" -X POST http://localhost:8080/self-service/registrations
|
|
curl -s -o /dev/null -w "with token-> %{http_code}\n" -X POST http://localhost:8080/self-service/registrations \
|
|
-H "Authorization: Bearer $tok"
|
|
|
|
# c) The openbaar register is anonymous and exposes only id + status (never the bsn):
|
|
curl -fsS http://localhost:8080/openbaar/register | jq
|
|
```
|
|
|
|
> The self-service token is validated against Keycloak's `digid` realm; the openbaar lookup needs no
|
|
> token (S-09). The generated contract lives at `services/bff/openapi.json` — S-08's client is built
|
|
> from it.

## S-05 — BIG Domain Service: submit a registration
|
|
|
|
**Outcome:** submitting a registration starts a Flowable process; the external-task worker
|
|
opens a zaak via the ACL and records it on the aggregate — the upstream half of the skeleton
|
|
that produces the zaak S-06 then projects.
|
|
|
|
**The path:** domain `POST /registrations` → Flowable `registratie` process → `OpenZaakAanmaken`
|
|
worker → ACL → OpenZaak; `GET /registrations/{id}` shows the opened zaak (ADR-0009).
|
|
|
|
```bash
|
|
# 1. Bring the full stack up (seeds config, builds our services, waits for health).
|
|
make up
|
|
|
|
# 2. Drive the full path end-to-end. This also seeds a published BIG zaaktype and points the
|
|
# ACL at it (the zaak's zaaktype URL is server-assigned, so it isn't known at bring-up).
|
|
make verify-domain # → "OK — the domain opened a zaak and recorded it on the registration"
|
|
|
|
# 3. Submit one yourself (domain on host port 8130). Returns 202 + a Location to read back.
|
|
loc=$(curl -fsS -D - -o /dev/null -X POST http://localhost:8130/registrations \
|
|
-H 'Content-Type: application/json' -d '{"bsn":"123456782"}' | sed -n 's/\r$//; s/^[Ll]ocation: //p')
|
|
|
|
# 4. The worker opens the zaak off the request path (eventual consistency, ADR-0009); poll
|
|
# until zaakUrl is filled. (Step 2 must have run first, so the ACL knows the zaaktype.)
|
|
curl -fsS "http://localhost:8130$loc" | jq
|
|
# → { "registrationId": "...", "status": "Ingediend", "zaakUrl": "http://.../zaken/api/v1/zaken/<uuid>" }
|
|
```
|
|
|
|
> Registration state is in-memory for this slice (ADR-0009); the rebuildable read model is the
|
|
> projection (S-06), fed by the very zaak this flow opens.

## S-06 — Event Subscriber + read projection
|
|
|
|
**Outcome:** a zaak created in OpenZaak flows through NRC to the Event Subscriber, which
|
|
projects it into a rebuildable read projection the projection-api serves.
|
|
|
|
**The path:** OpenZaak → (notification) NRC → (abonnement callback) Event Subscriber →
|
|
`register_projection` → projection-api `GET /register`.
|
|
|
|
```bash
|
|
# 1. Bring the full stack up (seeds config, builds our services, waits for health).
|
|
make up
|
|
|
|
# 2. Register the Event Subscriber's abonnement and create a zaak, then read it back.
|
|
# (The verify-projection check does exactly this end-to-end and asserts the result.)
|
|
make verify-projection # → "OK — projection-api serves zaak <uuid> with status INGEDIEND"
|
|
|
|
# 3. Observe the projection directly via the read API (host port 8120).
|
|
curl -fsS http://localhost:8120/register | jq
|
|
# → [ { "id": "<zaak-uuid>", "status": "INGEDIEND", "bsn": null, "naamPlaceholder": null } ]
|
|
|
|
# 4. Idempotency + rebuild: replays don't duplicate; a rebuild repopulates from the
|
|
# notification log (no OpenZaak access needed — ADR-0008).
|
|
curl -fsS -X POST http://localhost:8110/admin/rebuild # Event Subscriber, host port 8110
|
|
curl -fsS http://localhost:8120/register | jq 'length' # → unchanged
|
|
```
|
|
|
|
> `bsn` / `naam_placeholder` are deferred (ADR-0008) — the notification doesn't carry them and
|
|
> the subscriber may not read OpenZaak directly (§8.1). They surface in a later slice.
