SHOC Frontend (shoc-frontend-new)

Vite + React SPA for Sea Haven facility management (SHOC): work orders, vendor portal, uplifts, and related admin features. This is the selective rebuild of the legacy SHOC frontend — new code follows the IrisLoan.Admin conventions documented in docs/ARCHITECTURE_PLAN.md.

• GitHub: Sea-Haven-Industries/shoc-frontend-new
• Hosted at: https://dev.seahaven.com (dev environment; the only environment today)
• Backend API: https://api.dev.seahaven.com/api (called directly, cross-origin) — source: Sea-Haven-Industries/shoc-backend

Architecture

Static SPA hosting on AWS, provisioned by a CDK app local to this repo (infra/cdk/). CloudFront serves the built dist/ from a private S3 bucket; the SPA calls the backend directly over HTTPS at VITE_API_URL (no /api proxy at the CDN — the backend allows CORS).

Frontend stack: React 19, TypeScript, Vite, Tailwind CSS 4 + MUI, TanStack Query, React Router (via @generouted/react-router), React Hook Form + Zod, Ky HTTP client. Source layout: src/api/, src/domain/, src/app/ (see the architecture plan for the keep/discard migration matrix).

AWS Resources

Stack shoc-frontend-dev — CDK, account 396287094661, region us-east-1. Defined in infra/cdk/lib/frontend-stack.ts.

Resource	Name	Purpose
S3 bucket	seahaven-shoc-frontend-dev	Private origin (BLOCK_ALL, SSE, versioned; OAC-only reads)
CloudFront distribution	(stack output DistributionId)	HTTPS static hosting on dev.seahaven.com, ACM *.seahaven.com
CloudFront Function	SpaRewrite	Viewer-request rewrite of extensionless paths to /index.html (deep links)
IAM role	githubdeploy-shoc-frontend-new-dev	GitHub Actions OIDC deploy role, trust scoped to repo:Sea-Haven-Industries/shoc-frontend-new:ref:refs/heads/dev
Route 53 records	A/AAAA apex alias in zone dev.seahaven.com (Z07671212N75U4YLPWZR8)	Points the custom domain at CloudFront

No Lambdas, queues, or databases — this stack is static hosting only.

Configuration

Secrets

No Secrets Manager or SSM parameters. The one secret is a GitHub Actions repo secret:

Secret	Purpose
AWS_DEPLOY_ROLE_ARN	ARN of githubdeploy-shoc-frontend-new-dev, passed to the org reusable CD workflow

Environment variables (build-time, VITE_*)

Variable	Description	Dev value
VITE_API_URL	Ky API base prefix, baked into the build at vite build	/api (dev server) / https://api.dev.seahaven.com/api (production build)
VITE_API_TARGET	Dev-proxy target for /api (Vite dev server only)	http://localhost:5141

VITE_API_URL supplies the full API prefix — route paths in API_PATHS do not include /api. Absolute values must end with /api; vite.config.ts enforces this via config/api-url-contract.ts and fails the build otherwise. See .env.example, .env.development, and .env.production.

CDK context (domain, certificate ARN, hosted zone) lives in infra/cdk/cdk.json so CI runs cdk deploy with no flags.

Local Development

Requirements: Node.js ≥ 22.22.1 (CI/CD run Node 24), npm 11.16.0 (pinned via packageManager).

npm ci
cp .env.example .env   # then set VITE_API_URL=/api for local dev
npm run dev            # Vite dev server on port 3000, proxies /api → VITE_API_TARGET

The dev proxy expects the shoc-backend API at http://localhost:5141; override with VITE_API_TARGET (e.g. https://api.dev.seahaven.com to use the deployed dev API).

Command	Description
npm run dev	Start Vite dev server on port 3000
npm run build	Type-check (tsc -b) and production build to dist/
npm run preview	Preview the production build locally
npm test / npm run test:watch	Vitest unit tests (once / watch)
npm run test:e2e / npm run test:e2e:ui	Playwright e2e tests (headless / UI mode)
npm run lint / npm run lint:fix	ESLint (check / auto-fix)
npm run format / npm run format:check	Prettier (write / check)
npm run governance	Frontend governance checks (godfile + maintainability)
npm run verify	All gates: format + lint + build + test + governance

Husky + lint-staged run ESLint and Prettier on staged files at commit; commitlint enforces conventional commit messages. Run npx tsc --noEmit (or npm run build) before pushing to catch type errors early.

Contributing

• Branch from dev with a kebab-case description and a prefix matching the work: feature/, bug/, hotfix/, chore/, docs/, or refactor/ (e.g. feature/vendor-portal-filters, chore/sea-haven-branding).
• Commit messages follow Conventional Commits — commitlint rejects anything else at commit time.
• Open PRs against dev. Both dev and main are protected: every PR needs a green CI run and an approving review from a code owner (@Sea-Haven-Industries/internal-dev); new pushes dismiss stale approvals. Merged branches are deleted automatically.
• Promotion flow: feature/* → dev (auto-deployed and verified on dev.seahaven.com) → main (production promotion — no prod environment exists yet).

Deployment

CI/CD uses the org's reusable workflows (no stored AWS keys — OIDC only):

• CI (.github/workflows/ci.yaml) — on push and PRs to main/dev, calls Sea-Haven-Industries/.github → ci-typescript-frontend.yaml (Node 24): format check, lint, build, tests; and runs a repo-owned governance job that calls npm run verify so every gate (including the maintainability ratchets in scripts/governance-check.mjs) is guaranteed from this repository. Conventions and gates are documented under AGENTS.md, QUALITY_GATES.md, ARCHITECTURE_AND_CODE_QUALITY.md, and REVIEW_AND_PR_FRAMEWORK.md.
• CD (.github/workflows/deploy.yml) — on push to dev, calls Sea-Haven-Industries/.github → cd-cdk.yaml, which runs cdk deploy on infra/cdk (stack shoc-frontend-dev, us-east-1) and then scripts/deploy-web.sh: npm run build, aws s3 sync dist/ (hashed assets immutable, index.html never cached), CloudFront invalidation. Both run as the OIDC deploy role.

One-time provisioning (OIDC provider, CDK bootstrap, first local deploy, setting AWS_DEPLOY_ROLE_ARN) is documented in infra/cdk/README.md.

Manual deploy (emergency/reference only — needs credentials for the external-dev AWS account; the normal path is push to dev):

(cd infra/cdk && npx cdk deploy)
STACK_NAME=shoc-frontend-dev AWS_REGION=us-east-1 bash scripts/deploy-web.sh

Operations

• Verify: open https://dev.seahaven.com after a green Deploy run in the Actions tab; confirm a deep link (e.g. a work-orders route) loads directly and API calls succeed.
• Logs: deploy logs live in GitHub Actions (CI + Deploy workflows). There are no CloudWatch application logs — the stack is static hosting; runtime errors surface in the browser and on the backend API's side.
• Common failure modes:
  • Stale content after deploy — the CloudFront invalidation step failed or is still propagating; re-run the Deploy workflow or invalidate /* manually.
  • OIDC AssumeRole errors — the trust policy is scoped to pushes to dev on this repo; deploys from other branches/repos are rejected by design.
  • Broken API requests after a build — VITE_API_URL missing the /api suffix or carrying the wrong environment's host (it is baked in at build time).
  • CORS errors — the backend must allow the frontend origin; CloudFront does not proxy /api.
• CI and CD both fire on push to dev in parallel — a red-CI commit still deploys (matches the org's push-time-CD model; gating deploy on CI is known follow-up work).
