new-ssp	Bootstrap a new self-service portal from this repo as a template — what to keep, strip, rename, and re-seed. Use when starting a new SSP for a different domain/register.

New SSP from this template

The template's value is the enforced architecture (layer fences, token gate, a11y gate, API-drift gate) and the shared building blocks — not the BIG-register business content. Keep the machinery, replace the domain.

Run the script

Clone this repo, npm ci, then mechanise the mechanical parts (WP-45):

node scripts/create-frontend.mjs --name Kvk --context inschrijving

--name (PascalCase) replaces BigRegister.* everywhere; --context (lowercase Dutch ubiquitous term) is passed straight to gen:context (plop context, WP-44) to seed the new portal's first real context. Add --dry-run to preview file operations first, --keep <context> to leave one business context in place temporarily as a worked example, and --skip-backend if no .NET SDK is available yet (skips gen:api).

It strips the four business contexts and their wiring, renames the backend, re-runs gen:api, and seeds the first context — then prints a checklist for what it deliberately doesn't script: backend business rules and real branding can't be generated from nothing. Work through that checklist, keeping the GREEN gate below passing at every step.

Keep as-is

• src/app/shared/ — kernel (fp.ts), application (remote-data, store, submit), ui atoms/molecules, layout templates, upload subtree — except shared/ui/debug-state/, which the script deletes (see below).
• Tooling: eslint.config.mjs, .dependency-cruiser.js (edited by the script, not hand-stripped — see below), scripts/check-tokens.sh, .github/workflows/ci.yml, nswag.json, .storybook/, proxy.conf.json, .npmrc (legacy-peer-deps — and never npm audit fix --force, it downgrades Angular).
• src/app/auth/ (fake auth shell) and src/app/shared/infrastructure/scenario.interceptor.ts (dev-only).
• docs/reference/architecture/ ADRs 0001–0003 — the decisions still apply; amend, don't delete.
• CLAUDE.md, docs/reference/architecture/ARCHITECTURE.md, docs/reference/fp-tea-atomic-design.md — update names/examples as contexts change.
• .claude/skills/ — these recipes are the point of the template.
• src/app/beheer/ — its frontend is genuinely generic (data-driven off a StamdataTable/ AuditEntry shape, nothing BIG-specific). Its backend Stamdata catalog is not — see below.

Strip / replace — what the script does

• Business contexts registratie/, herregistratie/, brief/, showcase/: deleted (or one kept temporarily via --keep as the worked example while building the first real context — new-context + new-feature skills; if kept, update the worked-example paths in those skills to the new flagship context once you drop it for real).
• app.routes.ts route blocks and tsconfig.json aliases for removed contexts, and their CONTEXT_ALLOWED entry in .dependency-cruiser.js — boundary rules moved there in WP-38 and are no longer in eslint.config.mjs (which only keeps no-explicit-any + a11y template rules). Route stripping matches on the import alias a route uses, not its own path segment — beheer/zaken imports @registratie/ui/admin-cases.page and gets dropped along with registratie even though its own path doesn't say so.
• src/app/shared/ui/debug-state/ (the dev ⚙ state panel): imports @registratie/application/big-profile.store directly and is the one path .dependency-cruiser.js's shared-no-features rule exempts — there's no generic way to re-target it at an arbitrary new context, so it's deleted alongside registratie, along with its three wiring lines in shell.component.ts (import, imports: entry, template tag).
• The dashboard route is not deleted even though it currently imports @overzicht/ui/overzicht.page — too much else hardcodes /dashboard (login's post-auth redirect, authGuard's fallback, header nav/logo, breadcrumb trail, several stories/specs). The script rewrites its loadComponent to point at the freshly scaffolded --context page instead (a TODO(create-frontend) stopgap landing page, not a real overview).
• scripts/gen-snippets.mjs (showcase-only) + its package.json script entry + its CI/ ci-local.sh "showcase snippets drift" steps: deleted alongside showcase/ — they run unconditionally, so leaving them breaks npm run ci immediately once showcase/ is gone.
• Backend: keep the skeleton (Program.cs minimal-API style, ProblemDetails 422, X-Correlation-Id audit line, /api/v1 versioning, Contracts//Domain//Data/ split, test project, and the generic Stamdata/StamdataFile.cs+StamdataTable.cs reflection-driven /stamdata endpoint machinery, ADR-0004) — replace Data/SeedData.cs, Domain/* rules, Contracts/* DTOs, and the three concrete Stamdata catalog entries (Beroep/Opleiding/Specialisme/ProfessionMapping + their JSON) with the new register's. The script renames the solution/projects from BigRegister.* (and updates package.json's gen:api, ci.yml's paths, docker-compose.yml) — it does not rewrite business content; that's the printed checklist.
• Regenerate the seam: npm run gen:api (commits backend/swagger.json + src/app/shared/infrastructure/api-client.ts) — only reflects a new shape once the backend content above is actually rewritten.
• Branding: the script swaps src/index.html's stylesheet <link> + <title> to a placeholder path and creates an empty public/<name>-huisstijl/ — it cannot generate a real house style. Vendor your CSS there, then re-point the --rhc-* bridge in src/styles.scss (ADR-0003 pattern: bridge, don't rewrite tokens), then npm run check:tokens.
• docs/project/archive/backlog/ WPs, PRDs, and memory-specific docs — new portal, new backlog (keep docs/project/archive/backlog/README.md's WP process/template if you like the workflow). docs/reference/scaffolding.md also names BigRegister.Api in prose — update by hand.
• e2e/*.spec.ts (smoke.spec.ts, brief-v2.spec.ts, error-state.spec.ts): full BIG-register user-flow tests (BSN login → registration wizard → submission assertions). Not touched by the script (they don't block npm run ci — the e2e job runs separately) but are 100% stale business content; rewrite once you have real flows to test.

Verify — the GREEN gate must pass at every step

npm run lint && npm run check:tokens && npm test && npm run build
npm run build-storybook && npm run test-storybook:ci
cd backend && dotnet test && cd ..
npm run gen:api && git diff --exit-code backend/swagger.json src/app/shared/infrastructure/api-client.ts

Or just npm run ci for the non-storybook subset. Strip incrementally and keep this green — the fences are only worth having if they never go red.
